Two Techniques, Every Grill
Every grilling technique comes down to two fundamental methods: direct heat (food placed directly over the fire) and indirect heat (food placed away from the fire with the lid closed). Mastering when to use each — and how to combine them — is the single most important skill that separates beginners from confident grillers.
Direct heat is what most people picture when they think of grilling — burgers sizzling over flames, steaks developing a deep brown crust. Indirect heat is closer to oven roasting — slower, gentler cooking with the lid acting as an oven dome. Both methods work on any grill type, regardless of fuel source.
Direct Heat: Fast and High
Direct heat means placing food directly over the heat source — coals, gas burners, or the firepot. Temperatures at the grate surface typically range from 400°F to 700°F+ depending on your grill and fuel type.
Use direct heat for: Burgers, steaks, chops, boneless chicken breasts, fish fillets, shrimp, vegetables, and anything that cooks in 20 minutes or less. These foods are thin or small enough that the exterior develops a proper sear before the interior overcooks.
How it works: The intense radiant heat from below creates Maillard reaction browning — the complex chemical reaction responsible for the flavor and color of seared meat. Direct heat also causes fat to drip onto the heat source, creating small flare-ups that contribute additional flavor.
Key technique: Don't move food constantly. Place it on the grate and leave it alone for 3–4 minutes to develop a proper sear. Then flip once. Constant flipping prevents browning and extends cook time.
Indirect Heat: Low and Slow
Indirect heat means placing food away from the heat source with the grill lid closed. The lid traps heat and creates convection currents that cook food from all sides, similar to an oven. Temperatures typically range from 225°F to 375°F.
Use indirect heat for: Whole chickens, bone-in roasts, ribs, pork shoulder, brisket, thick-cut pork chops, beer-can chicken, and anything that needs more than 20 minutes to cook through. These foods would burn on the outside before the interior reaches the target temperature over direct heat.
How it works: With no direct flame beneath the food, cooking happens through convection (hot air circulating around the food) rather than radiation (direct heat from below). This allows large, thick items to cook evenly without the exterior charring.
Key technique: Keep the lid closed as much as possible. Every lid lift drops the temperature by 25–50°F and adds time to your cook. Resist the urge to peek — use a thermometer to monitor progress without opening the grill.
The Two-Zone Setup: Best of Both
The most versatile grilling configuration combines both methods simultaneously using a two-zone setup. This gives you a hot direct-heat zone for searing and a cooler indirect zone for finishing or resting food.
On a Charcoal Grill
Bank all your lit charcoal on one half of the charcoal grate, leaving the other half empty. The coal side is your direct zone (for searing). The empty side is your indirect zone (for finishing thick cuts or holding finished food at temperature).
On a Gas Grill
Light the burners on one side of the grill and leave the other side off. The lit side is your direct zone. The unlit side is your indirect zone. For a three-burner grill, you can light the two outer burners and leave the center off for a centered indirect zone.
On a Pellet Grill
Pellet grills inherently cook with indirect heat since the firepot is below a heat deflector. For direct heat searing, use models with a flame broiler slide (like Pit Boss) that opens a gap directly over the firepot, or use a separate searing accessory like the Camp Chef SideKick.
The reverse sear — the two-zone masterclass: Start thick steaks on the indirect side at 225–250°F until the internal temperature reaches 10–15°F below your target. Then move them to the hot direct side for 1–2 minutes per side to develop a sear. This produces the most evenly cooked steaks with a perfect edge-to-edge medium-rare interior and a crusty, brown exterior.

| Food | Method | Temp Range | Approx Time |
|---|---|---|---|
| Burgers (3/4" thick) | Direct | 400–450°F | 4–5 min per side |
| Steaks (1" thick) | Direct (or reverse sear) | 450–700°F sear | 3–4 min per side |
| Boneless chicken breast | Direct then indirect | 400°F direct, 350°F indirect | 6–8 min total |
| Bone-in chicken thighs | Indirect then direct | 350°F indirect, finish direct | 25–35 min |
| Whole chicken | Indirect | 325–375°F | 1–1.5 hours |
| Pork ribs (baby back) | Indirect | 225–275°F | 4–5 hours |
| Pork shoulder | Indirect | 225–250°F | 12–16 hours |
| Brisket | Indirect | 225–275°F | 12–18 hours |
| Vegetables | Direct | 400–500°F | 5–12 min |
Frequently Asked Questions
Can I smoke on a gas grill using indirect heat?
You can achieve light smoke flavor using a smoker box filled with wood chips on the lit side while cooking food on the unlit side. Gas grills lack the insulation and smoke circulation of dedicated smokers, so the smoke flavor will be milder, but it's a viable technique for adding smokiness to ribs, chicken, and roasts.
How do I know if food needs direct or indirect heat?
The general rule is thickness and cook time. If it cooks in under 20 minutes and is less than 1.5 inches thick, use direct heat. If it needs more than 20 minutes or is thicker than 1.5 inches, use indirect heat. Very thick items benefit from starting indirect and finishing with a direct-heat sear.
