What is a pellet grill?

Pellet grills are electric outdoor grills that are fueled by hardwood pellets. The capsule-sized pellets serve as both fuel for cooking food and a flavor enhancer that adds the taste of wood smoke. Incredibly versatile, pellet grills can smoke, grill, roast, bake, and braise. Thanks to a digital control board, they are easy-to-use and automatically maintain the desired cooking temperature for hours on end.

Why cook with a pellet grill?

The combination of versatility, flavor and set-it and forget-it technology make pellet grills who want the flavor of a charcoal grill and the ease and accuracy of a kitchen oven. They can smoke, grill, bake, roast, and braise at the touch of a button, infusing food with real wood smoke flavor. Better yet, pellet grills are easy-to-use and automatically maintain their temperature, so you can just set the temperature and walk away.

What can you cook on a pellet grill?

Because pellet grills combine the abilities of a grill, smoker, and kitchen oven, there’s no limit to what you can cook. You can grill burgers, hot dogs, chicken, seafood and vegetables; smoke authentic BBQ like ribs and brisket; slow-roast a turkey, tenderloin, or prime rib; braise short ribs; you can even bake pizza, bread pudding and blueberry pie.

How do pellet grills work?

Pellet grills rely on advanced digital technology working in concert with several mechanical parts. The grill is lit and the cooking temperature is programmed using a digital control board. It uses an algorithm to calculate how many pellets are needed to reach the desired temperature and how often those pellets need to be fed to the fire in order to maintain the temperature. A rotating auger then automatically feeds the pellets from the hopper to the fire, where a fan stokes the flames and distributes heat and smoke throughout the grill. To help maintain an even temperature throughout the entire grill and prevent flare-ups, a diffuser plate sits between the fire pot and grill grate. While the food cooks, the pellet grill continues to drop the perfect amount of pellets needed to maintain the desired temperature.

How do you use a pellet grill?

Pellet grills are incredibly easy-to-use. Just load your favorite pellets into the hopper, program the desired temperature on the controller and put your food on. That’s it. The pellet grill automatically maintains its temperature for as long as there are pellets to burn.

Do pellet grills need electricity?

Yes. Pellet grills are electric and require a standard 110v outlet to power the digital control board, auger, and fan.

Are pellet smokers the same as pellet grills?

Yes. Pellet grills go by many different names: pellet smokers, wood pellet grills, electric pellet smokers, electric smoker grills, and wood fired grills, just to name a few. They all refer to the same thing: a versatile electric outdoor cooker that’s fueled by hardwood pellets.

What is a Traeger®?

Traeger makes the most well known brand of pellet grills. Joe Traeger invented the pellet grill in 1985 and gave his name to it. Because of a patent, it was also the only pellet grill available for years. Since the patent expired, many different pellet grill brands on the market with more becoming available every year.

Is a pellet grill the same as an electric smoker?

No. Although both use electricity, they are different. Electric smokers cook food using a heating element and use wood chips or wood chunks to add smoke. They also tend to have a limited temperature range compared to pellet grills, making them good for smoking and slow-roasting at low temperatures, but not grilling, searing, or anything that requires higher temperatures.

What are wood pellets made from?

Often called smoker pellets or bbq pellets, the food-grade wood pellets that fuel a pellet grill are produced from 100% hardwood. Made of compressed sawdust sourced from lumber yard, sawmills, and trimmed treetops and limbs, the food grade pellets are all-natural and contain no fillers, although some pellets use vegetable oil as a lubricant.

Can I use heating pellets with my pellet grill?

Never use heating pellets to fuel a pellet grill. Heating pellets may contain impurities such as bark and leaves or could be sourced from softwoods like pine, which may be unhealthy to ingest and can leave food with an off taste. Those impurities may also cause the pellets to burn less cleanly, potentially causing problems with your pellet grill’s performance.

Where should I store my pellets?

Pellets should be stored in a dry place that’s safe from moisture and humidity. Excessive moisture can make the pellets difficult to light or cause the pellets to swell, which can cause jams in the grill. Many people use a covered 5 gallon bucket for storing their wood pellets.

Can I leave pellets in the hopper when I’m not cooking?

Yes, it’s okay to leave pellets in the hopper for a limited time after you’re done cooking. However, if you’re not going to be cooking on your pellet grill for several days, you may want to empty the hopper so that they don’t absorb any moisture from the air.

Can I cook on a pellet grill without using pellets?

No, the pellets are more than just a flavor enhancer, they also provide the heat for cooking food.

Does it matter what brand of pellets I use?

More important than the brand is the quality of the pellets. Many pellet grill makers state that you have to use their pellets on their grill (some even say you’ll void your warranty if you use another brand). This is their way of ensuring only use quality pellets (and selling some pellets in the process). However, any high-quality food-grade pellet will work with any pellet grill.

That being said, many cut-rate pellet brands don’t de-bark their wood, creating inconsistency in the pellets. That can prevent the pellets from burning cleanly, resulting in excessive ash that may interfere with airflow and cause temperature fluctuations. In fact, often when people are having trouble with their pellet grill, cheap pellets are the culprit. How do you know which pellets are okay? Be wary of any pellets with a price that seems too good to be true. A 20 pound bag should cost in the neighborhood of $16 - $23. If you see a bag priced significantly less, be skeptical of the quality.

How long does a bag of pellets last?

On average, a pound of pellets lasts between an hour and and an hour-and-a-half when smoking at 250°F in ideal conditions (75°F, no wind). When you increase the cooking temperature, the pellets burn more quickly. In cold weather, you’ll also burn pellets at a faster rate as the grill tries to maintain the desired temperature.

How many pounds of pellets does a pellet grill hopper hold?

It depends on the pellet grill. The average hopper holds about 18 pounds of pellets, allowing you to smoke for 18-24 hours continuously without having to add pellets.

Where can I buy smoker pellets?

You can find a huge variety of wood pellets in all kinds of flavors online. Now that pellet grills are becoming more popular, you should also be able to find them in many big box stores, although there won’t be as many brands or varieties to choose from.

What wood flavors do smoker pellets come in?

Wood pellets come in almost every imaginable hardwood variety. The most popular wood flavors are hickory, apple, cherry, pecan, oak, maple, mesquite and peach. You can pair flavors with specific foods to create a complimentary taste profile or mix them together to create layers of flavor.

I just bought a pellet grill. What pellet flavors should I get?

The two most popular flavors are hickory and apple. Between the two, you can cook anything. Hickory goes great with poultry and pork, but also has a strong enough flavor to stand up to red meat. Likewise, apple can be used with poultry and pork, but has a sweet and mild profile that pairs well with lighter fare like seafood and vegetables.

Are flavored pellets 100% of the flavor of the wood indicated on the bag?

Sometimes. However, often it’s a blend of woods. Many wood pellet makers start with a base of oak or alder that has a neutral flavor and provides a consistent burn then add the flavored wood for the desired taste.(Alternatively, some brands use essential oils from the flavored woods.) Because every type of wood burns differently—at different rates and temperatures—using a blend based on oak or alder offers a consistent burn and provide predictable heat output and burn rates. That way, whether you’re cooking with cherry or hickory, you can count on a pound of pellets to cook at roughly the same temperature and for the same length of time.

Do pellets produce the same smoke flavor as wood chips or wood chunks?

Because they burn so cleanly, pellet grills produce a cleaner, milder flavor than a traditional offset, which adds smoke flavor through both charcoal and wood chunks. Whether that’s a good or bad thing depends on your preference. Many people who don’t like a heavy smoke on their food prefer the lighter flavor produced by pellet grills. On the other hand, it might be a little light for those accustomed to the more aggressive smoke flavor produced by a traditional smoker.

How can I add more smoke on a pellet grill?

Cooking at a lower temperature produces more smoke, but some people also use an A-Maze-N Tube with their pellet grill to infuse their food with additional smoke.

What’s a P Setting?

Some pellet grills, such as Traeger Grills, have an adjustable knob called the P Setting. The P stands for Pause and it represents the delay between when the grill feeds pellets to the fire. The grill comes with a standard factory P Setting. By adjusting the P Setting, you can increase the pause, which allows the pellets to smolder longer and produce more smoke. However, since you’re also adjusting the pellet feed, adjusting the P Setting can come at the expense of temperature control.

Do I have to use pellets on a pellet grill or can I use a wood chips or chunks instead?

Only use food-grade wood pellets on your pellet grill. Never place wood chips or chunks on or around the fire pot. The fire could grow out of control, producing excessive heat that may damage vital electronics on the grill.

Can you cook food over an open flame on a pellet grill?

Pellet grills are primarily indirect cookers that use convection to cook food rather than the heat of a direct flame. A deflector plate sits between the fire pot and cooking grate to help keep temperatures consistent throughout the girl while also cutting down on hot spots and eliminating flare ups. Some pellet grills do have a direct grilling option, which allows you to grill over an open flame through an opening in the deflector plate.

Can you sear on a pellet grill?

You can sear on some pellet grills, but they are the minority. It’s generally accepted you need cook at a minimum of 500°F in order to sear. Because most pellet grills are primarily indirect cookers that top out at 400-425°F, they are not particularly good for searing. However, there are some pellet grills that can reach 500-700°F, as well as some that offer direct grilling options that allow you to sear meat over an open flame.

Can you cold smoke on a pellet grill?

No. Cold smoking is done at very low temperatures, usually between 70-80°F, but most pellet grills don’t go below 180°F. That limitation makes it fairly difficult to cold smoke on a standard pellet grill. However, some brands like Traeger and Louisiana Grills offer optional accessories that make it possible, and the Fast Eddy’s PG500 has a warming drawer that can be setup for cold smoking.

What is the controller?

The digital controller is the brains of the pellet grill. It’s the computer and uses a chip, sensors, circuits, and an algorithm to regulate the pellet grill’s temperature and make sure it accurately maintains the temperature programmed into the control board. The controller is probably the single most important part of your pellet grill, and how good the controller is usually determines how well the pellet grill performs.

Are all pellet grill controllers the same?

While all controllers are digital and utilize algorithms, they aren’t all the same. Some are more sophisticated than others, allowing for better temperature control. Some have knobs, while others have one-touch buttons. Some allow you to set temperatures in 25°F increments, while others can be programmed in 5°F increments. Controllers also differ in how well they maintain that temperature.

A standard digital controller feeds a predetermined amount of pellets to the fire in order to achieve the desired temperature. No matter what the grill’s internal temperature reads it will keep feeding that same amount of pellets. They can maintain a temperature within +/- 25°F. Most of the pellet grills on the market, particularly entry-level models, feature this type of controller.

A variation on the standard controller utilizes limits to tighten the temperature as needed. When the grill goes too far above or below the set temperature, reaching a predetermined limit, the grill will modify its auger cycle slightly to increase or decrease the amount of pellets fed to the fire. This is similar to how a typical kitchen oven works. These controllers can maintain about +/-15°F.

Finally, a PID (Proportional–Integral–Derivative) controller uses a more sophisticated algorithm and a feedback loop to precisely maintain its temperature. A PID controller constantly checks the grill temperature, compares it to the set temperature, and adjusts the pellet feed as necessary, allowing it to maintain a desired temperature within a few degrees.

I have an older pellet grill, can I upgrade the controller?

Very often you can upgrade the controller on an older pellet with an updated controller from the same brand. For instance, you can update an old Traeger 3 position (low-medium-high) controller with a newer Digital Elite or Pro Series controller. However, with some brands, new controllers may only work with specific models or models made after a certain year, so be sure to look for any exceptions or exclusions.

Can you update an old Traeger?

Yes, there are several ways to update older Traeger models. Traeger’s new controllers can be retrofitted to older models. You can also upgrade to a stainless steel fire pot, heat diffuser, and drip pan, which last longer and resist corrosion. Traeger also offers the option to upgrade the cooking and hopper lids to stainless steel.

Can I use a controller from one pellet grill maker on a pellet grill from a different brand?

It’s not recommended. Controllers aren’t universal. Even if the controller works on another grill, it may not perform as expected. Controllers are precisely tuned for a particular pellet grill, taking into account grill size, shape, and airflow, as well as the design of the fan and fire pot. These factors are not consistent from brand to brand, making it unlikely that a digital controller designed for one grill will perform nearly as well on an altogether different pellet grill.

Can you use a pellet grill in cold weather?

Yes. However, some pellet grills perform better in cold weather than others. Most pellet grills that use a standard non-PID controller have been tuned for ideal conditions. That means when a manufacturer claims their grill can maintain that +/- 20°F, they are referring to a 75°F day with no wind or precipitation. If it’s windy or cold, these grills tend to lose their ability to maintain that temperature range.

Because a PID controller constantly measures its temperature and adjusts its pellet feed to meet the desired temperature, it maintains its temperature just as well in cold weather as under perfect conditions.

Do you need to use an insulation blanket on a pellet grill in cold weather?

Because they are designed for optimum performance in perfect conditions, brands like Traeger recommend using an insulation blanket when temperatures drop below 35°F.

What is the best pellet grill?

While people always want a black and white answer, the truth is that the best pellet grill is the one that best fits your needs. Depending on budget, location, family size, and usage, that answer can change from person to person. Read more about how to choose the best pellet grill for you.

Are stainless steel pellet grills better?

Stainless steel pellet grills are more durable and will resist rust and corrosion better than a painted steel pellet grill.

Are heavier pellet grills made from thicker steel better?

While traditional offset smokers rely on beefy construction to hold and maintain their heat, pellet grills rely on their digital controller. A really good controller can accurately maintain the temperature on just about any pellet grill, regardless of its construction. So, if you’re looking at a heavy-duty pellet grill, you may be paying for extra steel you don’t actually need.

That being said, a well-constructed pellet may be more durable and prove to be more fuel efficient in cold weather.

Do pellet grills need to be seasoned?

No. Always follow the manufacturer’s guidelines, but a pellet grill shouldn’t need to be seasoned. Seasoning a grill or smoker is way to coat and protect parts that are vulnerable to rust, such as cast iron grates. However, most pellet grills are made from powder-coated steel or stainless steel, eliminating the need for seasoning. Some pellet grills often include instructions to run the grill cook at around 350°F for an hour or so, but this is just to burn off any manufacturing oil, not to season it.

Can I install a pellet grill into a counter top or island as part of an outdoor kitchen?

There are some built-in pellet grills available, notably by Memphis Grills. People will sometimes attempt to turn their stand-alone pellet grill into a built-in. However, it’s not recommended and may void your warranty. Installing a pellet grill into a counter top can alter airflow and the amount of heat it retains, affecting performance and potentially damaging the grill. Before undertaking any DIY project, always check with the manufacturer.

Do all pellet grills have inputs for connecting a meat probe?

Some, but not all, pellet grill controllers have inputs for meat probes, allowing you to monitor the internal temperature of your food on the LCD display. Of those that do have inputs, some include the probes with purchase, while others offer them as an optional accessory.

What are programmable meat probes?

In addition to monitoring your food’s internal temperature, programmable meat probes allow you to program the finishing temperature into the controller. When meat is done, the controller automatically lowers the grill’s temperature to keep food warm without overcooking it. However, not all meat probes are programmable. Programmable meat probes are generally found on more advanced pellet grills.

Are there WiFi pellet grills?

There are a few brands that make WiFi pellet grills (e.g. Memphis Grills and the Traeger Timberline). Some pellet grills with WiFi capability allow you to connect directly to your grill—in essence, the pellet grill becomes the network, giving you control within a limited range. Better WiFi pellet grills allow you to connect your grill to home your network, giving you the ability to control your grill via a cloud-based app or web page anywhere you have internet access.

Are there portable pellet grills for tailgating? What about extra large pellet grills?

Pellet grills come in every size, including portable pellet grills that are compact enough to be taken camping, tailgating, or just about anywhere, as well as extra large pellet grills that can be used for catering or a small business.

Do portable pellet grills need to be plugged in?

All pellet grills need electricity and so require a power source. There are, however, adapters that allow you to connect to your car battery or a portable 12v battery, allowing you the freedom to take use your pellet grill even when a standard outlet isn’t available.

How do you clean a pellet grill?

Like all grills, you should clean your pellet grill regularly, including removing any food and debris from the grates and diffuser plates. However, you should also clean any ash from your fire pot regularly. Ash buildup can affect the pellet grill’s airflow, as well as its ability to ignite the pellets and maintain a consistent temperature.

Do I need a cover for my pellet grill?

It’s also a good idea to invest in a grill cover to protect your pellet grill from the elements and keep it looking and cooking like new.

How much do pellet grills cost?

Pellet grills are available at a wide range of prices, from inexpensive bargain-priced models that cost as little as $399 to premium high-end models that cost $5,000 or more. In general, though, a medium-sized pellet grill of decent quality starts at around $699. If you're willing to go smaller, you can get a quality pellet grill for under $500. If you want more cooking space, expect to pay more money. As you add features PID temperature control, a direct grilling option, meat probes, WiFi, and stainless steel construction, the price tag goes up.

Are pellet grill prices comparable to gas grill prices?

No. On average, pellet grills cost more than gas grills because of the digital control board and automation, which require more technology and engineering. The difference in pricing often affects the perceptions and expectations of shoppers. While $400 might get you a high-quality gas grill with a generous cooking area, that same amount will likely only get you a small pellet grill or a cheap pellet grill that’s likely to break down in a year or two.
