Quick Answer: Buy a gas grill if you mostly cook quick weeknight meals — burgers, chicken, steaks — and want to light up and be eating in under 30 minutes; propane burners hit 500°F+ in 10-15 minutes with no prep beyond turning a knob. Buy a pellet grill if you want real wood-smoked barbecue — brisket, ribs, pulled pork — and are willing to trade speed for a PID controller that holds a set temperature for 12+ hours unattended. Gas wins on speed and searing heat (600°F+ vs a pellet grill’s ~450-500°F ceiling); pellet wins on flavor and hands-off convenience for long cooks. Most serious backyard cooks who can afford it eventually own both.
Pellet grills and gas grills solve two different problems, even though they look similar in a backyard photo. One is built to smoke for hours without you touching it. The other is built to get dinner on the table fast. Here’s the honest 2026 comparison, including where each one loses.
Pellet grill vs gas grill at a glance
| Factor | Pellet grill | Gas grill |
|---|---|---|
| Time to cooking temp | ~10-20 min | ~10-15 min |
| Max temperature | ~450-500°F (sear models higher) | ~600°F+ on most burners |
| Smoke flavor | Real hardwood smoke, all cook long | None from the fuel; only from drippings |
| Temperature control | Set a number, PID holds it (~5°F on good models) | Manual knob, direct heat under grates |
| Fuel cost | 1-3 lb/hr from a $15-25 20 lb bag | $15-20 per 20 lb propane tank |
| Needs power | Yes — auger, fan, controller | No (aside from optional accessories) |
| Entry price | ~$300-500 | ~$200-400 for a decent 3-4 burner |
| Best at | Low-and-slow, overnight, hands-off cooks | Weeknight speed, searing, quick dinners |
Speed: gas wins, and it isn’t close
A gas grill is built for Tuesday night. Turn a knob, wait 10-15 minutes for the burners to reach temperature, and start cooking. A batch of burgers or bone-in chicken thighs is on the table in well under 30 minutes total, and cleanup is a quick scrape of the grates.
A pellet grill takes a similar 10-20 minutes to reach temperature, but that’s where the similarity ends. The entire design exists to run long — a 14-pound brisket at 225°F takes 14-21 hours — so using one for a 20-minute weeknight dinner works, but it’s overkill: you’re running an auger, igniter and fan to cook something a gas grill handles just as well in the same time.
The weeknight pick: a 3-4 burner gas grill
- Lights instantly, no pellets or ash to manage.
- Reaches searing heat in 10-15 minutes.
- A capable 3-4 burner model runs roughly $200-400.

Flavor: pellet wins decisively
This is the entire reason to own a pellet grill. Compressed hardwood pellets burn and produce genuine wood smoke throughout the cook, so a brisket, rack of ribs or pork butt picks up real smoke ring and bark over hours on the grill.
Propane and natural gas are flavorless fuels. Any smokiness on a gas grill comes from fat and juices dripping onto the flame or a heat shield, which is a fraction of what a true smoker delivers. You can add a smoker box with wood chips to a gas grill, but it’s a workaround, not the same result as hours of continuous hardwood combustion. For a seared steak or a quickly grilled chicken breast, most people can’t taste a difference between the two fuels — the gap only shows up on long cooks.
Searing heat: gas usually wins
Gas grill burners commonly reach 600°F or hotter, which is proper steakhouse-crust territory. Most pellet grills top out around 450-500°F, which browns food well but doesn’t sear the way high, direct heat does.
Some pellet grills close the gap. Pit Boss builds a sliding flame-broiler plate into most of its lineup so food can sit over direct flame, and accessory sear grates help too — GrillGrate’s own claim for its Sear Station is “typically +100°F or more” above the surrounding grate. Neither fully replicates a dedicated gas grill’s burner output. If a hard sear on thick steaks is a weekly habit, a gas grill (or a charcoal kettle, per our pellet grill vs charcoal comparison) still does it better and faster.
Cost: gas is cheaper up front, pellet cost depends on cook length
A decent 3-4 burner gas grill runs about $200-400. A capable pellet grill starts higher — the Z Grills 700D4E runs roughly $450-550, and Traeger’s base Woodridge lists at $899 — though budget pellet models can be found nearer $300.
Fuel costs split by cook type. A 20 lb propane tank costs about $15-20 to refill and covers roughly 18-20 hours of grilling time at moderate heat, but burners running wide open for a hot sear session draw fuel fast. A pellet grill burns 1-3 pounds of pellets per hour, so a $15-25 twenty-pound bag covers a full overnight brisket smoke. For a quick burger night, propane is cheaper; for a 12+ hour smoke, pellets usually work out cheaper per hour of run time.
| Cook | Pellet grill | Gas grill | Cheaper |
|---|---|---|---|
| 30-min burger night | ~1-2 lb pellets, plus power | A few dollars of propane | Gas |
| 1-hour whole chicken | ~2-4 lb pellets | ~$1-2 of propane | Gas |
| 15-hour brisket | ~15-20 lb (≈one $15-25 bag) | Most gas grills aren't built for this cook | Pellet (by default) |
Convenience and maintenance
A pellet grill needs electricity for its auger, igniter, fan and controller, so it’s tied to an outlet or an inverter/generator. A gas grill needs nothing but a propane tank or a natural gas line, making it the simpler option for a patio with no nearby power.
Maintenance runs the other direction on ash and residue. A gas grill just needs the grates scraped and the burners checked occasionally. A pellet grill produces wood ash that has to be cleaned from the fire pot, and Traeger’s own official guidance calls for a deep clean every 2-3 cooks (about 20-24 cook-hours) to keep the auger and igniter running reliably.
Who actually buys which
Gas grills remain the default backyard cooker for most U.S. households — fast, simple, and inexpensive to run. Pellet grills are the smaller but fast-growing category: according to the Hearth, Patio & Barbecue Association, pellet-grill ownership roughly tripled from 3% to 9% of U.S. households in two years (Rockbridge research, September 2021), while about 70% of U.S. households own some kind of grill or smoker overall. That growth pattern — most buyers adding a pellet grill rather than replacing a gas grill — is the strongest signal that the two fill different roles rather than compete directly.
The bottom line
Buy a gas grill if speed and simplicity matter most: dinner in under 30 minutes, no pellets to store, no ash to clean, and a lower entry price. Buy a pellet grill if you want real smoked barbecue and are willing to plan around longer cook times: a PID controller that holds temperature for 12+ hours, genuine wood-smoke flavor, and a warranty that now runs a decade on Traeger’s main lines.
