Two Zone Grilling: How to Set Up and Use Heat Zones
Two-zone grilling means setting up your grill with a hot, direct-heat zone on one side and a cooler, indirect zone on the other. The direct zone sears food; the indirect zone cooks it through with the lid closed. It is the single most useful technique to learn on a gas grill – it solves the most common grilling problem: food that is charred on the outside but raw in the middle.
What Two Zone Grilling Solves
Without heat zones, everything on the grill is over direct flame at the same temperature. This works for thin, fast-cooking foods – sausages, burgers, thin chicken breasts. For anything thicker, it creates a problem: the exterior chars before the interior reaches a safe temperature.
A two-zone setup solves this. Sear the exterior over direct heat to develop color and crust. Move to the indirect zone and close the lid – the food finishes cooking in an oven-like environment at a lower temperature, with no risk of burning the exterior.

How to Set Up Two Zones on a Gas Grill
On a 2-burner grill
- Turn the left burner to high (direct zone).
- Leave the right burner off (indirect zone).
- Preheat with the lid closed for 10-15 minutes before cooking.
The indirect zone on a 2-burner grill runs at approximately 275-325°F when the lid is closed with one burner on high. Adjust the direct burner to medium-high if you want a lower indirect temperature.
On a 3- or 4-burner grill
- Turn the left one or two burners to high (direct zone).
- Leave the right one or two burners off (indirect zone).
- Preheat with the lid closed for 10-15 minutes.
A 4-burner grill gives more flexibility: two burners on high create a larger direct zone; one burner on high and one on medium creates a graduated temperature transition between zones that is useful for more complex cooks.
On a charcoal grill (for reference)
- Push all the lit charcoal to one side of the grill (direct zone).
- Leave the other side empty (indirect zone).
- The indirect zone runs at approximately 225-300°F depending on the amount of charcoal used.
How to Use the Two Zones: The Technique
The zone technique follows a consistent pattern for most proteins:
- Preheat the grill fully with the lid closed – 10-15 minutes.
- Season and prepare the food. Pat proteins dry before placing on the grill.
- Place food on the direct zone first. Sear for 2-3 minutes per side until the exterior has developed color and grill marks. Do not move during searing – the food releases naturally when a crust forms.
- Move food to the indirect zone. Close the lid.
- Cook until the internal temperature reaches your target. Use a meat thermometer – do not rely on time alone.
- Optional: move back to direct heat for 1-2 minutes at the end to re-crisp the exterior if it has softened during the indirect phase.
The lid closed on the indirect zone is essential – it creates the convection heat that cooks the interior. Opening the lid on the indirect zone drops the temperature and significantly extends cook time.
Which Foods Use Two Zones?
| Food | Zone approach | Method |
|---|---|---|
| Thick steaks (1.5"+) | Both zones | Sear 2-3 min per side on direct, finish to temp on indirect |
| Bone-in chicken pieces | Both zones | Sear skin-side on direct for color, cook through on indirect (lid closed) 20-25 min |
| Burgers (standard) | Direct only | 4-5 min per side on direct – no need for indirect |
| Sausages | Direct only | Medium direct heat, turn frequently – indirect not needed |
| Whole chicken | Indirect mainly | Brief sear all over on direct, then indirect (lid closed) until 165°F – 60-75 min |
| Pork ribs | Indirect mainly | Indirect only, lid closed, 225°F zone for 2-3 hours. Optional: finish 2 min direct for caramelization. |
| Vegetables | Direct only | Direct medium-high, 4-6 min tossing – char and caramelization are the goal |
| Fish fillets | Direct only | Direct medium-high – quick cook, 3-4 min per side |
Temperature Management
The indirect zone temperature depends on the direct-zone burner setting and the lid position.
- Direct on HIGH, lid closed: indirect zone runs approximately 325-375°F – good for chicken pieces and thick chops.
- Direct on MEDIUM-HIGH, lid closed: indirect zone runs approximately 275-325°F – good for low-and-slow ribs and whole chicken.
- Direct on MEDIUM, lid closed: indirect zone runs approximately 225-275°F – useful for very slow cooks.
Check the indirect zone temperature with a thermometer placed at grate level on the indirect side. The lid thermometer reads the overall ambient temperature, not the grate temperature on the indirect side specifically.
Common Mistakes
- Opening the lid during indirect cooking – every opening loses 25-50°F and adds 10-15 minutes to the cook. Only open to check temperature.
- Not searing long enough before moving to indirect – the sear develops flavor and color. Move too early, and the food cooks through on the indirect zone without adequate crust development.
- Placing food directly over the gap between zones – food at the edge of the direct zone may get uneven heat. Place it clearly in the indirect zone, away from the direct burner.
- Not preheating the indirect zone – the indirect zone needs to be warm before food goes on. Preheat the whole grill for 10-15 minutes with the lid closed before starting.

Frequently Asked Questions
What is two-zone grilling?
Two-zone grilling means setting up the grill with a hot direct heat zone (lit burners) on one side and a cooler indirect zone (unlit burners) on the other. Sear food over direct heat to develop color and crust, then move it to the indirect zone to finish cooking through with the lid closed. It solves the common problem of food that is charred outside but raw inside.
How do you set up two zones on a gas grill?
Turn one or two burners on one side to high (direct zone) and leave the burners on the other side off (indirect zone). Preheat with the lid closed for 10-15 minutes before cooking. On a 2-burner grill: left burner high, right burner off. On a 4-burner grill: left two burners high, right two burners off.
What foods need two-zone grilling?
Any food that is too thick to cook through over direct heat without burning the exterior. Thick steaks (1.5"+), bone-in chicken pieces, whole chicken, and pork ribs all benefit from two-zone cooking. Thin foods – burgers, sausages, fish fillets, vegetables – generally cook well on direct heat alone.
How long does indirect grilling take?
It depends on the cut and the indirect zone temperature. Bone-in chicken pieces take 20-25 minutes on indirect at 325°F after searing. A whole chicken takes 60-75 minutes. Ribs take 2-3 hours at a lower indirect temperature (225-275°F). Always use a meat thermometer to verify doneness – time alone is not reliable.
Do you need to close the lid for indirect grilling?
Yes – the closed lid is what creates the convection heat environment that cooks the food in the indirect zone. Without the lid closed, there is no heat circulating around the food – it would just sit in a cooler area of the grill without cooking through. Keep the lid closed during the indirect phase, and open it only to check the internal temperature.
