Mastering Indirect Grilling for Large Roasts
Large roasts, such as whole tenderloins or bone-in rib roasts, are prone to burning on the outside before the center is cooked through. By moving the fire to the perimeter and the meat to the center, you control the pace of the cook, ensuring a uniform roast from edge to center.
Control the airflow to manage the temperature.
The secret to a successful roast is maintaining a steady, low-to-medium heat. Keep your grill lid closed as much as possible to prevent heat loss.

What goes in.
- 5-6 lbBeef rib roast or pork loin
- 2 tbspKosher salt
- 1 tbspCoarse black pepper
- 3 clovesGarlic, minced
- 2 tbspNeutral oil with high smoke point
Creating the Cold Zone
Position your coals on one side of the grill grate or ignite only the outer burners of your gas grill. The goal is a steady ambient temperature between 325°F and 350°F in the unlit area.
The method.
Prepare the meat
Bring your roast to room temperature for 45 minutes before cooking. Pat the exterior completely dry with paper towels to ensure a brown crust.
Set up the grill
If using charcoal, bank lit coals to one side. If using gas, turn off the burners directly under where the roast will sit. Place a drip pan under the unlit grate to catch fat.
Position the roast
Place the roast in the center of the cool zone. Insert your thermometer probe into the thickest part of the meat, avoiding the bone.
Maintain heat
Close the lid. Monitor the grill thermometer; adjust vents or burner dials to maintain 325°F. Do not lift the lid for the first hour.
Check for doneness
Once the internal temperature is 10-15 degrees below your target, start checking every 10 minutes. Remove the roast when it hits the final target temperature.
Rest the meat
Transfer the roast to a cutting board and tent loosely with foil for 20 minutes before carving.
Other turns to take.
Wood-Infused Roast
Add 2-3 soaked hickory or oak wood chunks to the coals once the roast is on the grill for a subtle smoke character.
When it doesn't go to plan.
Always place a foil drip pan underneath the roast to prevent flare-ups from dripping fat.
Use a digital probe thermometer that stays in the meat; opening the lid to check temp ruins the ambient heat environment.
If the exterior is browning too quickly, move the roast further away from the heat source.
The ones that keep coming up.
Do I need to flip the roast during cooking?
No. Because the heat is circulating evenly around the meat, flipping is unnecessary and only causes heat loss.
How do I know if the grill is at the right temperature?
Trust the lid thermometer, but keep a secondary thermometer at grate level for accuracy.
