To grill barbecue a gas grill, set up two heat zones, keep the lid closed, and cook at a steady 225°F to 275°F for low-and-slow meats, or use direct heat only for quick items. A gas grill can make real barbecue-style food, but you need indirect heat, wood smoke and patience to get close to a offset smoker or pellet grill.

Why a Gas Grill Can Do Barbecue at All

Barbecue is really about three things: low temperature, long cook times and smoke. A gas grill delivers heat from burners below the cooking grates, which makes it easy to hold a steady temperature. Many owners find that the main limit is not the heat but the smoke. Gas produces less smoke than wood or charcoal, so you have to add it on purpose.

Brisket, pork shoulder, ribs and chicken thighs all work well on a gas grill when you control the heat. Long cooks of four to ten hours are realistic, provided you have enough propane and a thermometer you trust.

The Factors That Make or Break Gas Grill Barbecue

Indirect heat setup. Light only the outside burners and place the meat over the unlit center. This keeps fat from dripping onto open flame, which causes flare-ups and bitter smoke. Some grills have a third burner that makes this easier, and Features and Benefits of a Three-Burner Gas Grill explains how that layout helps.

Temperature control. Built-in lid thermometers often read 25°F to 50°F off from the cooking grate. Place a separate probe thermometer at grate level to see the real temperature. Adjust the burner knobs in small increments and wait several minutes between changes.

Smoke source. Use wood chips in a smoker box or a foil pouch with holes poked in it. Hickory, oak and cherry are common choices for beef and pork. Soak chips only if your manufacturer recommends it, because many pitmasters prefer dry chips for cleaner smoke.

Fuel and airflow. Keep at least a quarter tank of propane for long cooks, or hook up a larger tank. Make sure the vents on the lid and the bottom are not blocked, since airflow affects both temperature and smoke flavor. If you are choosing a model for this kind of cooking, Gas Grill Buying Guide: Features, Fuel, and Performance covers the features that matter most.

Grate condition. Dirty grates hold old residue that tastes bitter at low heat. Scrape them before and after each cook. Problems with worn grates are covered in Weber Gas Grill Grate Problems: Causes and Fixes.

How to Grill Barbecue on a Gas Grill, Step by Step

  1. Trim meat and apply your rub at least an hour before cooking, or overnight for brisket and pork shoulder.
  2. Preheat the grill with the outside burners on high for 15 minutes, then lower to your target temperature, usually 225°F to 275°F.
  3. Place a foil pan of water on the unlit section if you want more moisture, which also helps stabilize the temperature.
  4. Add wood chips to the smoker box or foil pouch once smoke starts to thin, and place it over a lit burner.
  5. Set the meat over the unlit center, fat side up for brisket, and close the lid.
  6. Check the internal temperature with a probe. Pull pork shoulder around 195°F to 203°F and brisket around 198°F to 205°F, or when a probe slides in like soft butter.
  7. Rest large cuts wrapped in towels in a cooler for at least an hour before slicing.

Common Mistakes and What to Do About Them

Most problems come from opening the lid too often, which drops the temperature and stalls the cook. Another common issue is cooking directly over the burners, which chars the outside before the inside is done. If your food tastes like nothing but gas, you probably need more wood or a longer smoke at the start. Pitmasters also recommend letting the grill run at full temperature for a while before adding meat, so the grates and wood settle in.

What We’d Use

A grill with three or more burners and a built-in thermometer gives you the most room to set up two zones and hold low heat. Top 6 Propane Gas Barbecue Grill Picks for Backyard Cooks in 2026 lists several options worth comparing.

  • Weber Genesis 2 Gas Grill, a three-burner model many owners use for indirect cooking. View on Amazon
  • Weber Smoker Box with a stainless steel lid, which holds wood chips for steady smoke. View on Amazon
  • Digital probe thermometer with a wired grate probe, for checking real cooking temperature. View on Amazon

What temperature should I use for barbecue on a gas grill?

Most barbecue is cooked between 225°F and 275°F. Lower temperatures take longer but give more tender results for brisket and pork shoulder.

Can I use wood chips on a gas grill?

Yes. Place chips in a smoker box or foil pouch over a lit burner. Dry chips burn cleaner than soaked ones, though some owners prefer soaking.

Do I need a separate smoker box?

Not always. A foil pouch with holes poked in it works, but a dedicated box is easier to reuse and refill during a long cook.

How long does brisket take on a gas grill?

Expect eight to twelve hours for a whole packer brisket at around 250°F, depending on size and how well the grill holds heat.

Is it safe to cook low and slow on a gas grill?

Yes, when the grill is in good working order and you keep vents clear. Check hoses and connections for leaks before cooking, and consult the manufacturer’s manual for safe operating guidance.
