7 Steps to Cook the Perfect Tomahawk Steak on a Gas Grill
To cook the perfect tomahawk steak on your gas grill, start by choosing a thick, well-marbled cut. This ensures the steak stays juicy and flavorful throughout the grilling process. Let it come to room temperature before seasoning it generously with salt and your favorite spices.
Next, set your gas grill for two-zone cooking—high heat on one side for searing and low heat on the other for roasting. Sear each side of the steak for a few minutes until you get that beautiful crust.
Then, move the steak to the cooler side of the grill to finish cooking indirectly until it’s almost done.
Finally, don’t forget to rest the steak before serving. This step locks in all those delicious juices, making every bite tender and tasty. Follow these simple steps closely, and you’ll reveal the secrets to a flawless tomahawk steak grilled to perfection.
Key Takeaways
- Select a 2-inch thick, well-marbled, prime-grade tomahawk steak with a clean, intact bone for best flavor and even cooking. This cut really shines when it’s thick and juicy.
- Bring the steak to room temperature and dry brine it with coarse salt for 2 hours. After that, season it evenly with salt, pepper, and garlic powder to kick up the flavor.
- Preheat your grill on high to 500°F for searing. Then, set up a two-zone fire, leaving one side on low heat for indirect cooking.
- Sear the steak over high heat for 3-4 minutes per side with the lid open. Once seared, move it to the indirect heat side and close the lid until the internal temperature hits 115-120°F.
- Let the steak rest, covered loosely with foil, for 10-15 minutes before slicing. This step helps the juices redistribute, making it tender and flavorful every time.
Selecting the Right Tomahawk Steak

When selecting the right tomahawk steak, focus on a cut that’s at least 2 inches thick with bright red color and abundant white marbling. The marbling should be consistent throughout the steak, as this fat distribution is key for juiciness and flavor.
Choose a steak graded choice or prime to ensure tenderness and quality. Don’t forget to verify that the bone is intact and clean; this not only improves presentation but also helps you handle the steak easily during cooking.
Selecting a tomahawk steak with these characteristics sets you up for a delicious, evenly cooked meal. By paying attention to thickness, color, marbling, and grade, you’ll guarantee a superior steak that’s ready to impress on the grill.
Preparing and Seasoning the Steak

After choosing the perfect tomahawk steak, the next step is to prepare and season it properly to bring out its full flavor. First, remove the steak from the refrigerator at least 60-90 minutes before cooking to let it reach room temperature. This helps ensure even cooking throughout.
Pat the steak dry, then dry brine it by generously seasoning all sides with coarse salt. Let it rest on a cooling rack for 2 hours. This step really enhances the flavor and helps the meat retain moisture.
Next, apply a simple seasoning blend—salt, freshly ground black pepper, and garlic powder—or your favorite steak rub if you want extra taste. Before grilling, make sure the steak is evenly coated with seasoning and free of any excess moisture.
Finally, let it rest after seasoning. This allows the salt to penetrate the meat, improving tenderness and flavor during cooking.
Setting Up Your Gas Grill for Two-Zone Cooking

To set up your gas grill for two-zone cooking, start by preheating it on high for 10-15 minutes. This gets the grates hot enough for searing, which is key.
Next, turn on only one or two burners to create an indirect heat zone around 225-275°F. Leave the other burners off or on low to maintain a direct high heat area.
This setup lets you control the cooking process perfectly. You can move your tomahawk steak between zones as needed to get the best results.
Burner Configuration Tips
Although it might seem simple, setting up your gas grill for two-zone cooking is essential to mastering the perfect tomahawk steak. Start by using a gas grill with at least two burners.
Preheat all burners fully to get an accurate grill temperature, then turn one side off or down to low for indirect heat. This burner setup allows you to sear the steak over high heat before moving it to the cooler zone to finish cooking gently.
Keep the high-heat burner between 400-500°F during searing for ideal crust formation. Position your steak with the bone facing the heat source to ensure even heat distribution.
Use a reliable thermometer to monitor grill temperature and adjust burners as needed for consistent results. It’s a simple trick that really makes a difference!
Heat Zone Arrangement
When you set up your gas grill for two-zone cooking, you create a precise environment that lets you sear your tomahawk steak over direct high heat and then finish it gently on indirect low heat. Start your grill setup by turning on one or two burners to establish a high-heat zone for searing.
Leave the other burners off to form the indirect cooking zone, where the temperature should stay between 225-275°F. Use your grill’s lid thermometers and adjust burner controls to maintain this low heat area.
Position your steak with the bone facing the heat source to avoid overcooking the cap. This heat zone arrangement guarantees you get a perfect sear while allowing the steak to cook evenly through indirect cooking.
Preheating Best Practices
Since achieving the perfect sear depends on high heat, you should preheat your gas grill on high for at least 15 minutes until the grates reach around 500°F. This guarantees the hot zone is ready for a great sear.
To set up a two-zone cooking environment, turn one burner to maximum heat and keep the others off or low. Close the lid during preheating to maintain a consistent high temperature. Use a grill thermometer to confirm the hot zone hits about 500°F.
After that, adjust the burners to maintain roughly 225°F on the cooler side for even cooking.
- Preheat on high for 15 minutes to reach ideal searing temperature
- Create a hot zone and an indirect cooler zone for two-zone cooking
- Use a thermometer to verify and maintain proper temperatures throughout
Searing the Tomahawk Steak Over High Heat
To develop a rich, caramelized crust on your tomahawk steak, you’ll want to sear it over the highest heat your gas grill can reach, usually around 500°F or more. Preheat your grill thoroughly to guarantee the grates are scorching hot.
Place the steak directly over this high heat zone, keeping the bone away from the flames to avoid overcooking the marrow. Keep the grill lid open to maintain maximum surface temperature.
Flip the steak every 30 to 60 seconds using tongs—never puncture the meat—to build an even crust and prevent burning. Aim for about 3 to 4 minutes searing per side.
Frequent repositioning guarantees consistent contact with the grill grates, giving you those perfect, flavorful grill marks and a beautifully seared exterior.
Roasting the Steak Using Indirect Heat
Although the initial sear locks in flavor, you’ll want to finish cooking your tomahawk steak using indirect heat. This guarantees it cooks evenly without burning.
Set your gas grill to indirect heat by turning on one burner and leaving the others off, aiming for 225-275°F. Place the steak on the cooler side with the bone facing away from direct heat.
Keep the grill lid closed to maintain consistent temperature and moisture.
To roast your steak properly:
- Use the indirect heat zone for slow, even cooking
- Keep the grill lid closed to retain heat and moisture
- Monitor the internal temperature, aiming for about 115-120°F before the final sear
This method ensures your steak cooks through gently and evenly.
Monitoring Internal Temperature for Perfect Doneness
When cooking your tomahawk steak, you’ll want to keep a close eye on its internal temperature to achieve the perfect doneness. Use a reliable probe or instant-read thermometer—not the grill’s built-in gauge—to check the internal temperature regularly.
Remove your steak about 5°F below your target doneness to allow for carryover cooking. Here’s a quick guide:
| Doneness | Internal Temperature (°F) | Action |
|---|---|---|
| Rare | 120 | Remove at 115°F |
| Medium-Rare | 130 | Remove at 125°F |
| Medium | 140 | Remove at 135°F |
| Medium-Well | 150 | Remove at 145°F |
Monitoring temperature precisely ensures your steak cooks exactly how you like it. It’s the best way to get that perfect cook every time.
Resting and Serving Your Tomahawk Steak
Pull your tomahawk steak off the grill once it reaches the right temperature, but don’t rush to slice it just yet. You need to let it rest for 10-15 minutes to allow the juices to redistribute and the internal temperature to stabilize. This step is vital for a juicy, tender steak.
To rest and serve your steak perfectly: cover it loosely with foil to retain heat without trapping moisture. Avoid slicing too early to prevent juice loss, especially with thick cuts.
Serve slices immediately after resting to enjoy maximum flavor and moisture. Trust me, waiting those extra minutes makes all the difference!
