The Quick Take
Direct heat means cooking food directly over the fire at temperatures between 500°F and 1,000°F to sear meat and lock in flavor. Indirect heat means cooking adjacent to the fire at temperatures between 250°F and 400°F, allowing thicker cuts of meat to cook all the way through gently. For the best results, use a two-zone setup: sear your food first over the roaring fire, then slide it over to the indirect zone until it reaches your target internal temperature.

Setting Up Your Heat Zones
Setting up a two-zone fire is usually a hassle of piling charcoal on one side of a standard grill and leaving the other side empty. But when you are cooking on an Arteflame grill, direct and indirect heat zones happen naturally by design. You build a wood or charcoal fire right in the center. The removable center grill grate hits temperatures over 1,000°F, giving you the ultimate direct heat source for a steakhouse-quality sear.
Meanwhile, the flat solid-steel cooktop that surrounds the center grate absorbs that heat and disperses it outward. The inner edge of the cooktop stays piping hot for aggressive roasting, while the outer edge remains much cooler for indirect, gentle cooking. You don't need to fiddle with dials, move coals around, or worry about flare-ups since the grease drains inward into the fire. You simply slide your food closer to or further from the center.
Whether you are using an Arteflame or setting up a traditional grill, the goal is always the same: control the fire, don't let the fire control you. You need a designated hot zone for creating that beautiful brown crust and a designated safe zone where food can coast to the perfect internal temperature.
Step-by-Step Instructions
- Prep the grill. Pour a little vegetable oil on three paper napkins, place them in the center of your grill, stack firewood over the napkins, and light the paper.
- Establish the fire. Let the wood burn for about 20 minutes to create a hot coal bed in the center and thoroughly heat the surrounding solid-steel cooktop.
- Sear over direct heat. Place your meat directly over the center fire grate. Sear for 2 to 3 minutes per side to develop a rich, flavorful crust.
- Move to indirect heat. Once the crust is formed, slide the food off the center grate and onto the cooler outer edge of the flat steel cooktop.
- Monitor internal temperature. Let the food cook gently in the indirect zone until a meat thermometer confirms it has reached your desired doneness.
- Clean up easily. While the cooktop is still warm, scrape any food residue directly into the center fire, then wipe the steel with a cloth and a thin coat of oil.
Pro Tip: Always oil your food lightly before placing it on the grill, rather than trying to oil a blazing hot grate. This prevents sticking and ensures an even, edge-to-edge crust during the direct heat phase.
Common Mistakes to Avoid
- Cooking everything over the roaring flames. Unless you are trying to forge a sword, chicken thighs do not need 1,000°F heat for twenty minutes. Sear them quickly, then move them to the outer edge to finish.
- Playing the guessing game with doneness. Poking a steak and comparing it to the squishiness of your thumb is a great way to serve medium-rare poultry. Invest in a high-quality, fast-reading thermometer from ThermoWorks to know exactly when your meat is ready to pull from the indirect heat.
- Applying sweet BBQ sauces too early. Sugar burns into a bitter, black mess over direct heat. Wait until your meat is resting safely in the indirect heat zone before brushing on your favorite Kinder's BBQ sauce.
- Flipping your food like it owes you money. Put the meat down over the direct heat and leave it alone so a crust can form. Grab a pair of sturdy OXO grilling tongs and only flip once the meat releases naturally from the steel.
Make It Your Own
Once you understand how to manipulate direct vs indirect heat, the entire culinary world opens up. You can start playing with techniques that combine the two zones for incredible results. Here are a few ways to level up your two-zone game:
- The Reverse Sear: Cook a thick steak on the cooler, indirect edge until it hits 115°F, then move it to the roaring center grate for a final, blistering sear.
- The Sizzle and Slide: Sear burgers over the direct fire, then slide them to the indirect zone to melt the cheese slowly without burning the bottom bun.
- Vegetable Zoning: Blister bell peppers over the open flames, while gently caramelizing onions in their own juices on the cooler outer rim.
Frequently Asked Questions
Can you use indirect heat without a lid?
Yes, you can absolutely use indirect heat without a lid. On an open-fire grill with a flat steel cooktop, the conductive heat from the steel gently cooks the food from the bottom up, while the ambient heat of the fire radiates outward. Just flip the food occasionally for an even cook.
How long should I sear meat over direct heat?
You should sear meat over direct heat for about 2 to 3 minutes per side. This is enough time to develop a rich, brown crust at temperatures over 600°F without overcooking the interior of the food.
What foods should only be cooked on indirect heat?
Large, tough, or highly fatty cuts of meat like whole chickens, briskets, and thick pork roasts should be cooked primarily on indirect heat. Cooking them directly over a roaring fire will burn the exterior to a crisp long before the inside reaches a safe and tender temperature.
Keep the Fire Going
Mastering direct and indirect heat is your official graduation from "guy who burns hot dogs" to true backyard pitmaster. You now hold the secret to steaks that are perfectly crusted on the outside and juicy on the inside, and you will never again have to scrape the charred remains of a chicken breast into the dog's bowl. (Don't worry, we won't tell anyone about last summer). The best part is that with a solid-steel cooktop and an open fire, setting up these heat zones is as natural as breathing. Just light the wood, find your hot spots, and let the grill do the heavy lifting. When dinner is done, your Arteflame easily converts into a fire pit so you can kick back and enjoy the evening.
