Choosing The Right Tomahawk Steak
Choosing the right tomahawk steak is the foundation for a memorable grilling experience. This cut is impressive on its own, but the quality and size you select can make all the difference in flavor and cooking time. Before you fire up your gas grill, take a moment to focus on the details that matter most.
Selecting Quality Meat
Look for a tomahawk steak with rich marbling. The fat running through the meat melts during cooking, making each bite juicy and flavorful. Choose steaks with a bright red color and firm texture to ensure freshness.
Don’t hesitate to ask your butcher where the beef comes from. Grass-fed or grain-fed options can affect taste and tenderness. Have you ever noticed how some steaks just taste better? Quality meat is the reason why.
Thickness And Weight Considerations
Thickness plays a huge role in how long you’ll grill your tomahawk steak. Most tomahawks range between 1.5 to 2 inches thick, but thicker cuts need more time on the grill. A steak that’s too thin can cook too fast and dry out.
The weight also matters—tomahawks typically weigh between 30 to 45 ounces. Heavier steaks require patience and careful temperature control to cook evenly. Have you thought about how your grill’s heat zones will handle a large, thick cut?
Preparing The Steak
Getting your tomahawk steak ready before it hits the grill is crucial for a perfect cook. The way you prepare the steak affects both flavor and texture. Small steps here can make a big difference on your gas grill.
Seasoning Techniques
Start with a simple seasoning approach. Salt is your best friend; it enhances the natural flavors and helps create a beautiful crust. Use kosher salt or sea salt and sprinkle it evenly on both sides.
Adding freshly ground black pepper is a classic choice. You can also experiment with garlic powder, smoked paprika, or dried herbs for extra depth. Avoid over-seasoning—let the meat shine through.
Some chefs like to season the steak a few hours ahead and let it rest uncovered in the fridge. This dry brining method draws out moisture and then reabsorbs it, intensifying flavor and improving the crust.
Bringing To Room Temperature
Take your steak out of the fridge at least 30 to 60 minutes before grilling. Cold meat cooks unevenly and can toughen the texture. Letting it reach room temperature ensures more consistent cooking.
During this time, cover the steak loosely with a clean cloth or plate to keep it clean. This simple pause lets the meat relax, so when you place it on your gas grill, it cooks evenly from edge to center.
Have you noticed how your steaks sometimes come out too rare inside or burnt outside? This step helps avoid that problem. It’s a small adjustment that guarantees a better grilling result every time.
Setting Up Your Gas Grill
Setting up your gas grill correctly is key for cooking a perfect tomahawk steak. It ensures even cooking and the right sear. Proper grill setup helps you manage heat and control cooking times easily.
Creating Heat Zones
Divide your grill into two heat zones: direct and indirect. The direct zone is where the flames are strong. It is perfect for searing the steak. The indirect zone has little or no heat. Use this area to cook the steak slowly after searing.
To create heat zones:
- Turn on one or two burners for high heat.
- Leave the other burners off or low for indirect heat.
- Place the steak on the hot side first for searing.
- Move it to the cooler side to finish cooking.
Preheating Tips
Preheat your gas grill for 10 to 15 minutes before cooking. This warms the grill grates and ensures steady heat. Close the lid while preheating to trap heat inside.
Check the temperature using a grill thermometer. Aim for about 450°F (232°C) in the direct heat zone for searing. Preheating also helps prevent the steak from sticking to the grill.

Grilling Times For Tomahawk Steak
Grilling a Tomahawk steak on a gas grill requires precise timing to get the perfect doneness. The thickness of the steak and the heat of your grill both play crucial roles. Knowing the right grilling times helps you serve a steak that’s juicy and cooked just the way you like it.
Rare To Medium-rare Cooking Times
For a rare to medium-rare Tomahawk steak, aim for about 4 to 5 minutes per side on high heat. This usually means grilling at around 450°F to 500°F. After searing, let the steak rest for 5 to 10 minutes to let the juices redistribute.
If your steak is very thick, use a two-zone cooking method: sear first over direct heat, then move it to indirect heat to finish. The internal temperature should be between 120°F and 130°F for rare, and 130°F to 135°F for medium-rare. Using a meat thermometer is the best way to ensure accuracy.
Medium To Well-done Cooking Times
Cooking your Tomahawk to medium or well-done takes longer—typically 6 to 7 minutes per side for medium and up to 10 minutes or more for well-done. Keep the grill heat moderate, around 350°F to 400°F, to avoid burning the outside while ensuring the inside cooks fully.
After searing, move the steak to indirect heat and close the grill lid to cook through evenly. Check the internal temperature regularly: 140°F to 145°F for medium, 150°F to 160°F for well-done. Patience here pays off; rushing can lead to a tough, dry steak.
Grilling Techniques
Grilling a tomahawk steak on a gas grill demands skill and patience. The right techniques make all the difference. Let's explore effective ways to ensure a deliciously cooked steak.
Searing The Steak
Searing locks in the steak's juices. Start by preheating the grill to high heat. Place the tomahawk steak on the grill's hottest section. Grill each side for about 3 to 4 minutes. This creates a perfect crust.
Indirect Cooking Method
After searing, switch to indirect heat. Move the steak to a cooler part of the grill. Close the lid and let it cook slowly. Maintain a temperature of 250°F to 300°F.
Cook until the internal temperature reaches your desired level. For medium-rare, aim for 130°F. Use a meat thermometer for accuracy. This method ensures even cooking throughout.
Using A Meat Thermometer
Using a meat thermometer is the best way to cook a tomahawk steak perfectly. This tool shows the steak's exact temperature inside. It helps avoid guessing and ensures the steak cooks just right.
Checking Internal Temperatures
Insert the thermometer into the thickest part of the steak. Avoid touching the bone, as it gives a false reading. The ideal temperatures for tomahawk steak are:
- Rare: 120-125°F (49-52°C)
- Medium rare: 130-135°F (54-57°C)
- Medium: 140-145°F (60-63°C)
- Medium well: 150-155°F (65-68°C)
- Well done: 160°F+ (71°C+)
Check the temperature often for the best results. This practice ensures the steak is cooked to your taste.
Avoiding Overcooking
Remove the steak from the grill a few degrees before your target temperature. The steak continues to cook while resting. This carryover heat prevents overcooking.
Rest the steak for 5 to 10 minutes. This step locks in juices and improves flavor. Using a meat thermometer helps you catch the perfect moment to take the steak off the grill.
Resting And Serving
After grilling your tomahawk steak to perfection, resting and serving become the final, crucial steps. These moments allow the juices to redistribute, ensuring every bite bursts with flavor. How you rest and carve the steak can make all the difference between a good meal and a memorable one.
Importance Of Resting
Resting your tomahawk steak for about 10 to 15 minutes after grilling is essential. This pause lets the meat fibers relax and the juices settle back inside, preventing them from spilling out when you cut. If you slice too soon, you risk losing the rich, flavorful juices that make a steak so satisfying.
During resting, loosely cover the steak with foil to keep it warm without trapping steam. Have you ever noticed how a steak tastes different right off the grill compared to after a few minutes of rest? That difference is the magic of proper resting.
Carving Tips
Carving a tomahawk steak might feel intimidating due to its size and bone, but a few simple tips make it easier. Start by slicing against the grain; this breaks up muscle fibers and results in tender, easy-to-chew pieces. Use a sharp knife for clean cuts that preserve the steak’s juicy texture.
- Remove the bone carefully by cutting along its edge if you prefer boneless slices.
- Slice the steak into ½-inch thick pieces to balance tenderness and portion size.
- Serve slices on a warm plate to maintain the steak's temperature.
Imagine the difference between a rough, uneven cut and one where each slice is perfectly tender and juicy. Which would you rather serve your guests? Paying attention to these carving details elevates your grilling experience and impresses everyone at the table.

Common Mistakes To Avoid
Cooking a tomahawk steak too long can make it dry and tough. Avoid using very high heat, which burns the outside before the inside cooks. Checking the steak’s temperature often helps prevent overcooking.
Cooking a tomahawk steak on a gas grill can be a culinary adventure, but it's easy to make mistakes that can ruin your meal. While achieving that perfect sear and juicy interior might seem straightforward, certain missteps can easily lead to disappointment. Let's explore some common mistakes to avoid for a perfectly grilled tomahawk steak.
Grilling Too Fast
Patience is key when grilling a tomahawk steak. One common mistake is cranking up the heat too high and rushing the grilling process. While a high temperature is essential for searing, cooking the steak too fast can result in a burnt exterior and an undercooked interior. Instead, use a two-zone grilling method. Start with high heat to sear the steak for a few minutes on each side, then move it to a cooler part of the grill to finish cooking evenly. This method ensures that the steak cooks at a consistent pace, allowing the juices to distribute properly.
Skipping The Resting Period
You're hungry, and the steak looks delicious right off the grill. But cutting into it immediately is a mistake you'll want to avoid. Skipping the resting period can cause the juices to spill out, leaving your steak dry and less flavorful. Allow your tomahawk steak to rest for at least 10-15 minutes after grilling. This resting period lets the juices redistribute throughout the meat, ensuring every bite is tender and succulent. As tempting as it might be to dive right in, a little patience goes a long way in enhancing the flavor and texture of your steak. Have you ever found yourself cutting into a steak too soon? Next time, try the resting period and notice the difference it makes in your dining experience.
