What Are Pellet Grills?
A pellet grill, also known as a pellet smoker, is an outdoor cooker that combines the convenience of gas grilling with the flavor of wood smoking. It uses compressed hardwood pellets as fuel and relies on electricity to feed pellets into a fire pot, ignite them, and regulate temperature through a digital controller.
This hybrid system makes it possible to smoke, bake, grill, sear, roast, and even braise—all on one machine. The set-it-and-forget-it nature of pellet grills has made them especially popular among backyard BBQ fans, competition teams, and culinary hobbyists alike.
Pellet Grills vs Other Types of Cookers
| Grill Type | Fuel | Temp Control | Smoke Flavor | Ease of Use |
|---|---|---|---|---|
| Pellet Grill | Wood Pellets + Electricity | Automated (Digital) | Moderate to Strong | Very Easy |
| Gas Grill | Propane/Natural Gas | Manual Knobs | Very Low | Easy |
| Charcoal Grill | Charcoal | Manual (Vents) | Strong | Medium |
| Offset Smoker | Wood or Charcoal | Manual (Fire Management) | Very Strong | Difficult |
Pellet grills strike a balance between flavor and convenience. You get real smoke flavor with digital precision—no need to babysit a firebox all day.
Main Components of a Pellet Grill
To understand how pellet grills work, it helps to know the basic parts:
- Hopper: Holds the wood pellets (usually 10–30 lbs capacity)
- Auger: A motorized corkscrew that moves pellets from hopper to fire pot
- Fire Pot: Where pellets are ignited and burned for heat and smoke
- Igniter Rod: Electrically heats up to ignite pellets
- Combustion Fan: Circulates air to maintain fire and distribute heat evenly
- Drip Tray: Catches grease and blocks direct flame
- Controller: The “brain” that adjusts pellet feed and fan speed to maintain temperature
High-end pellet grills like the BARQ 2400 and 3600 also feature WiFi controllers, downdraft exhaust systems, and insulated fireboxes for pro-grade results.
How Pellet Grills Work: Step-by-Step
Here’s how a pellet grill functions from startup to shutdown:
- Fill the Hopper: Add food-grade wood pellets (like oak, hickory, or cherry).
- Power On: Plug in the grill and turn it on via the controller.
- Preheat: The igniter rod heats the pellets in the fire pot until they ignite.
- Pellet Feeding: The auger automatically delivers more pellets based on the temperature setting.
- Fan Circulation: The fan keeps air moving for clean combustion and even heat distribution.
- Cook Time: Set your desired temp and let the controller manage the cook.
- Shutdown: Initiate the shutdown cycle to burn off excess pellets and cool the fire pot safely.
This automated cycle is what makes pellet grills so approachable—even for beginners who’ve never used a smoker before.
Pellet Grill Controller Types
Pellet grill performance is largely determined by the type of controller:
- 3-Position (Low/Med/High): Old-school, minimal precision
- Digital Dial: Basic digital temp control in 25°F increments
- P.I.D. Controller: Proportional Integral Derivative system offers ultra-stable temps and smoke control
- WiFi-Enabled: Monitor and control your grill from your phone, even while you’re inside watching the game
Brands like Green Mountain Grills offer PID WiFi controllers as standard—so you can check brisket temps without leaving your couch.
About the Pellets: The Fuel Behind the Flavor
Pellets are made from compressed sawdust, usually from hardwoods like oak, maple, cherry, and hickory. They burn cleanly and produce steady, flavorful smoke. Different wood types affect the flavor profile of your meat:
- Hickory: Bold, bacon-like flavor (great for ribs and brisket)
- Cherry: Mild and sweet (pairs well with pork and poultry)
- Oak: Balanced, neutral smoke (good all-purpose choice)
- Mesquite: Intense smoke (best for beef in small doses)

Common Misconceptions About Pellet Grills
- “They don’t create real smoke.” False—especially at low temps. You can get excellent smoke flavor at 180–225°F.
- “They’re just for beginners.” False. Many competition teams use pellet grills for precision cooking.
- “They can’t sear.” Also false. With a cast iron grate or sear plate, pellet grills can hit 500°F+.
FAQs About How Pellet Grills Work
Are pellet grills electric?
Yes. They use electricity to power the controller, auger, fan, and igniter—but the heat source is real wood.
Do I have to babysit the grill?
No. Once the temp is set, the grill runs itself. You only need to add pellets and monitor food temps.
How long does it take to cook on a pellet grill?
It depends on what you’re cooking. Brisket = 10–14 hours. Ribs = 5–6 hours. Chicken = 1–2 hours.
Can I grill with the lid open?
No. Pellet grills rely on closed-lid cooking to circulate heat and smoke properly.
Do I need special pellets?
Yes—use food-grade BBQ pellets only. Never use heating pellets, which can contain chemicals.
