Direct vs. Indirect Heat, and When to Use Each
Direct heat sears at 450 to 550 F, indirect heat cooks through at 300 to 375 F. Learn when to use each and stop burning the outside while the inside stays raw.
Charred outside and pink inside is one mistake with one cause. The food sat over the fire when it needed to sit beside it.
Direct and indirect describe where a piece of food sits relative to the flame (that is the entire concept). Learn to read which one a food wants and the burnt edges stop, the raw centers stop, and the flare-ups go with them.
This one idea fixes more grilling problems than any gadget you can buy, and it costs nothing except the five seconds it takes to look at what you are cooking.
What direct heat is
Direct heat is food cooking right over the flame or the coals, with the grate running 450 to 550 F and the food browning fast off the radiant heat coming up from below.
Use it on anything thin that cooks in under about 10 minutes. Steaks under an inch, burgers, hot dogs, shrimp, thin pork chops, and sliced vegetables all live here.
These foods want a hard sear and a short stay, and leaving them out there longer only dries them out while the crust you already built goes bitter.
The tell is speed. Cooks in a few minutes per side? Direct.
What indirect heat is
Indirect heat is food cooking beside the fire with the lid down. The grill turns into an oven, circulating hot air at a gentler 300 to 375 F, and the food cooks through without scorching.
Use it on anything thick or slow. Bone-in chicken pieces, whole chickens, roasts, thick 2-inch steaks, ribs, and pork shoulder all need real time to reach a safe internal temperature, and direct heat would burn the outside long before the center caught up.
The tell is time and thickness, so anything that needs 15 minutes or more, or measures thicker than about an inch, starts on the indirect side and stays there until the center is nearly where you want it.
The problem this actually fixes
Cooking everything over high direct heat is the number one beginner mistake (and the reason so much backyard chicken comes off black).
Bone-in chicken thighs have to reach 175 F inside, and that takes 30 to 40 minutes. Over open flame the skin goes black at 10 minutes with the inside still raw.
Flare-ups make it worse. Fat drips onto open flame, the fire jumps up, and the outside chars in seconds. On the indirect side no flame sits under the food at all, so a drip has nothing to ignite on.
So move the food off the flame. The center gets its time and the outside stays under control.
How to know which one to use
Two questions sort almost any food you are likely to put on a grill.
The first question is thickness. Under about 3/4 inch means direct, and anything thicker leans indirect (at least to start).
The second question is time, and under 10 minutes total means direct while anything longer starts indirect and finishes with a sear (that sear is the last 2 minutes, never the first 20).
| Food | Method | Target |
|---|---|---|
| Burgers, hot dogs | Direct | 450 F, 3 to 4 min per side |
| Thin steak (under 1 in) | Direct | 500 F, 2 to 3 min per side |
| Shrimp, sliced veg | Direct | 450 F, 2 to 4 min total |
| Bone-in chicken thighs | Indirect, then sear | 350 F to 175 F inside |
| Whole chicken | Indirect | 375 F, about 60 min, 165 F breast |
| Ribs, pork shoulder | Indirect | 250 F, several hours |
| Thick steak (1.5 in +) | Indirect, then sear | 275 F to 130 F, then hot sear |
The combo move most pros use
The best cooks rarely pick one method and ride it through the whole cook.
Sear and finish is the first pattern. Brown a thick steak or chop over direct heat for a minute a side, then slide it to the indirect side to reach its final temperature gently (crust and clean interior, in that order).
Roast and sear is the second. Cook chicken pieces on the indirect side until they are nearly done at 165 F, then move them over direct heat for 2 to 3 minutes to crisp the skin.
Same two zones with the order swapped, because chicken skin crisps best at the end of a cook and a bone-in thigh wants its sear last.
Bone-in chicken thighs, worked end to end
Build a two-zone fire with the cool side at 350 F. Six bone-in, skin-on thighs go on the indirect side (skin up, always), lid closed.
Cook 25 to 30 minutes with the lid down, until the thickest thigh reads 165 F on an instant-read.
Then move all six over direct heat, skin down, for 3 minutes to crisp and brown, pulling them at 175 F.
Skin crisp. Meat juicy. And nothing burnt, because the two zones did two different jobs at two different points in the cook.
Frequently asked questions
What is the difference between direct and indirect heat?
Direct heat is food cooking right over the fire at 450 to 550 F, for fast searing. Indirect heat is food cooking beside the fire with the lid down at 300 to 375 F, so it cooks through gently like an oven.
When should I use indirect heat?
Use indirect heat on anything thick or slow. Whole chickens, bone-in pieces, roasts, ribs, and thick steaks all belong there. Anything that needs 15 minutes or more should start on the indirect side.
Can I do direct and indirect on a gas grill?
Yes. Light the burners on one side and leave the others off. The lit side is your direct zone and the unlit side is your indirect zone, which is exactly what a two-zone fire is (no special equipment involved).
Why does my food keep catching fire on the grill?
Flare-ups happen when fat drips onto open flame under the food. Move the food to the indirect side. No flame sits beneath it there, so a drip has nothing to catch on and the flare-ups stop.
Do I need the lid down for indirect cooking?
Yes. Indirect heat runs on trapped hot air circulating around the food, so the lid stays down. Cooking with the lid open loses the oven effect entirely, and everything slows way down.
