Direct grilling puts food right over the fire. Use it for thin foods that cook in under about 20 minutes: burgers, thin steaks, chops, sausages, fish fillets and vegetables.
Indirect grilling puts food beside the fire with the lid closed, so the grill works like an oven: about 325–375°F for roasting, or 225–275°F for smoking. Use it for anything thicker than about 1.5 inches or on the bone: whole chicken, bone-in pieces, roasts, ribs and thick steaks. Many of those finish with a minute or two over direct heat for color.
Set up both zones on every cook, so you always have a hot side to brown and a cool side to escape to. Thin goes over the fire; thick goes beside it.
| Method | Heat | Lid | Best for | Typical time |
|---|---|---|---|---|
| Direct | Over the fire, medium to high | Open or closed | Thin, quick foods | Under about 20 minutes |
| Indirect | Beside the fire, low to medium | Closed | Thick or bone-in foods | 30 minutes to many hours |

What is the difference between direct and indirect heat?
Direct heat browns the surface; indirect heat cooks the center.
Over the fire, most of the heat hits food as radiant energy from the coals or burners. It drops off fast with distance, so the side facing the fire browns in minutes while the center lags behind.
Beside the fire with the lid closed, hot air circulates around the food and cooks it from every side. It's slower and gentler, so a whole chicken cooks through before the skin burns.
Browning needs a dry surface well above the boiling point of water. That's why food cooked only on the cool side stays pale until it gets a turn over the coals.
This is direct heat: right over the coals, the crust forms in minutes, so leave it alone until it releases.
When should you use direct heat?
Use it whenever the outside and inside will be done at the same time.
Thin foods cook through in the time it takes the surface to brown, so they never need the cool side. Preheat with the lid closed until the grate is fully hot; our guide on how long to preheat a grill gives times by fuel.
Use high heat for thin steaks and chops, and medium to medium-high for burgers, sausages, chicken breasts, fish and vegetables. Lay food down and leave it until it lets go of the grate, then flip once. If it tears, the grate was too cool or you moved it too soon; why food sticks to the grill covers each cause.
Keep the lid open for very thin foods you're watching closely, and closed for anything that needs a few extra minutes to cook through.
When should you use indirect heat?
Use it whenever the outside would burn before the center is done.
Thick cuts and anything on the bone need time for heat to reach the center. Over direct heat, bone-in chicken chars outside while staying raw at the joint; beside the fire, it cooks evenly and the skin renders.
Roasting heat on the cool side suits whole chicken, bone-in pieces and roasts. Smoking heat with wood added turns the cool side into a smoker for ribs, pork shoulder and brisket. Our guides on how to smoke chicken and how to smoke ribs walk through those cooks.
Keep the lid closed. Every time you open it, the hot air that does the cooking escapes and the cook stretches out.
Indirect heat in action: the shoulder smokes beside the fire while steaks sear directly over the coals.
Step-by-Step: Set Up a Two-Zone Fire
Five steps give you a hot side and a cool side on any grill with a lid.
Step 1 of 5Build the hot side
Target: all the heat on one side of the grill
On charcoal, pour a lit chimney of coals onto one half of the charcoal grate. On gas, plan to light only the burners on one side.
Step 2 of 5Leave the other side empty
Target: nothing burning under the cool side
Push every coal to one side so the cool side has none beneath it, or leave the burners under it off. Set a drip pan under the cool side for long or fatty cooks to catch drips and cut flare-ups.
Bank the coals tight against one wall so the cool side stays truly cool.
Step 3 of 5Preheat with the lid closed
Time: about 10–15 minutes
Close the lid and let the grates heat through. Scrape them clean once they're hot.
Step 4 of 5Set the top vent over the cool side
Target: charcoal grills only
Turn the lid so the top vent sits above the food. That pulls heat and smoke across the food instead of straight up from the coals.
Step 5 of 5Cook, then move the food
Done when: the thickest part hits its target temperature
Start thick foods on the cool side with the lid closed, then move them over the fire for the last few minutes to brown. Check doneness with an instant-read thermometer and our meat temperature chart.
How do you set up two zones on your grill?
Every grill with a lid can do it; only the layout changes.
| Grill | Direct zone | Indirect zone |
|---|---|---|
| Charcoal kettle | Coals banked on one side or held in an insert | The empty side, top vent above it |
| 2-burner gas | One burner on | Other burner off; the cool side runs warmer |
| 3-burner gas | One or two burners on one end | The burner at the far end off |
| 4+ burner gas | Outer burners on | Middle burners off |
| Kamado | Grate with no heat deflector | Heat deflector in place |
| Pellet grill | Flame broiler or sear plate, if fitted | The whole cooking chamber |
A 22-inch kettle has room for both zones, one reason it's our top charcoal pick in the Weber Original Kettle 22 review. A curved charcoal insert holds the coals in place on long cooks; it's built into the SnS MasterKettle.
On gas, a three-burner grill gives a clean split. When we tested the Weber Spirit E-325, the boosted Sear Zone ran 90–110°F hotter than the standard burners, so it doubles as a strong direct zone for the final sear.
On gas, keep the lid shut during indirect cooks or the cool side never gets hot enough.
Pellet grills cook indirectly by design, because a heat baffle sits between the firepot and the food. That's why most struggle to sear and why the Pit Boss Navigator 850 adds a slide-out flame broiler.
Should you sear first or last?
For thick cuts, sear last; for thin cuts and chicken pieces, either works.
Searing at the end gives thick steaks and roasts more even doneness from edge to edge. The surface also dries on the cool side, so it browns faster when it hits the fire. Our reverse sear method gives times and pull temperatures.
Searing first works fine for thinner cuts and bone-in chicken thighs. Brown them over the fire, then move them to the cool side to finish.
Thick cuts keep rising roughly 5–10°F while they rest, as heat moves from the hot outside to the center, so pull them a little below your target. For whole cuts of beef, pork and lamb, USDA's safe minimum is 145°F with a 3-minute rest; ground meat needs 160°F and poultry 165°F.
Why is your two-zone cook going wrong?
Most problems come from using the wrong zone or having no cool side.
Find your sign and change one thing on the next cook.
Burnt outside, raw inside
Sign
a charred crust over meat that's still pink at the bone.
Fix
- Move the food to the cool side and close the lid until it reaches temperature.
- Next time, start bone-in and thick foods on the cool side from the beginning.
Expect
an evenly cooked center, browned at the end over the fire.
Pale with no crust
Sign
food that's cooked through but gray or blond on the outside.
Fix
- Finish it over the hot side for 1–2 minutes per side.
- Pat the surface dry before it goes on the grill.
Expect
a browned crust without overcooking the center.
Flare-ups with nowhere to go
Sign
flames lick the food, leaving black soot patches.
Fix
- Move the food to the cool side until the flames die down.
- Never spread coals wall to wall or light every burner.
Expect
short flare-ups you control instead of chase.
Cool side too hot
Sign
food on the indirect side browns or burns on the bottom.
Fix
- Use fewer coals, or turn the lit burner down.
- Put a drip pan or a sheet of foil under the food as a shield.
Expect
gentle, even cooking with little browning until you move the food.
Watch out: lifting the lid to check can double an indirect cook. Use a leave-in probe so you can read the temperature with the lid shut.
Cold and wind pull heat out of the cool side first. On blustery days, shield the grill and add fuel or turn up the lit burners. For keeping a charcoal fire steady, see our charcoal grill temperature control guide.
Which grill is best for two-zone cooking?
Pick one wide enough that the cool side really stays cool.
Small grills make two zones hard, because the cool side sits only a few inches from the fire. A 22-inch kettle or a three-burner gas grill is about the minimum for a comfortable split.
- Charcoal on a budget: a 22-inch kettle with coals banked to one side.
- Gas: three or more burners, so one end can stay off.
- Smoke and sear on one fire: a kettle with a charcoal insert.
- Thick steaks most nights: follow how to grill the perfect steak for timing on each side.

Frequently Asked Questions
01What is the difference between direct and indirect grilling?
Direct grilling cooks food right over the fire; indirect grilling cooks it beside the fire with the lid closed. Direct heat browns the surface fast, so it suits thin foods done in under about 20 minutes. Indirect heat surrounds the food with hot air like an oven, at about 325–375°F for roasting or 225–275°F for smoking.
02When should you use indirect heat on a grill?
Use it whenever the outside would burn before the center is done. That means anything thicker than about 1.5 inches or on the bone: whole chicken, bone-in pieces, roasts, ribs and thick steaks. Keep the lid closed so the hot air does the cooking, then give the food a minute or two over direct heat at the end for color.
03Do I need a drip pan for indirect grilling?
On long or fatty cooks, yes. Set it under the cool side, beneath the food, to catch fat before it hits the coals or burners. That cuts flare-ups, keeps the grill cleaner and stops grease from pooling in the bottom. For quick indirect cooks like bone-in chicken pieces, a pan is optional but still makes cleanup easier.
04Can I cook indirect on a 2-burner gas grill?
Yes. Light one burner, put the food over the other and close the lid. The cool side sits close to the lit burner, so it runs warmer than on a bigger grill; turn the food once halfway so both sides cook evenly. A three-burner grill gives a cleaner split, with the far burner off.
05Do I flip food on indirect heat?
Rarely. The circulating air cooks food from every side, so flipping adds little and opening the lid lets the heat escape. Rotate it once if one side faces the fire and browns faster. Use a leave-in probe so you can track the temperature with the lid shut, then move the food over the fire to brown.
06Is direct or indirect heat better for steak?
Direct heat for steaks under about 1 inch, since the center finishes in the time the crust forms. Steaks 1.5 inches or thicker do better on indirect heat first, then a sear over the fire. Searing last gives more even doneness and a drier surface that browns faster. Pull thick cuts a little early, because they rise 5–10°F while resting.
07What is a three-zone fire?
A hot zone, a medium zone and an empty cool zone on one grill. On charcoal, the medium zone gets a thin layer of coals; on gas, a burner on low. It lets you sear, cook through and hold food at once. It needs at least a 22-inch kettle or a three-burner gas grill, because smaller grills leave too little space between zones.
08Does indirect heat reduce charring?
Yes. Charring compounds form more at high heat over long cook times and when fat drips onto flames. Cooking thick foods beside the fire keeps them away from both, and a drip pan under the cool side catches the fat. Finish with only a minute or two over direct heat for color instead of grilling thick cuts over the coals the whole time.
The Takeaway
Match the heat to the food's thickness: thin over the fire, thick beside it, and a quick sear to finish. Build two zones every time so you always have somewhere to move food.
Once the setup feels easy, put it to work on a smoked chicken or a reverse-seared steak.
