How Long Tomahawk Steak In Oven

If you’re planning a special meal, knowing how long tomahawk steak in oven is the key to success. This impressive cut can seem intimidating, but with the right timing, you can achieve perfect medium rare results every time. The process combines a reverse sear method for even cooking and a beautiful crust. We’ll walk you through each step, from prep to plating.

This guide gives you a clear, simple roadmap. You’ll learn exactly what to do and when to do it. Let’s get your steak ready for the oven.

For a perfect medium rare tomahawk steak, the oven time is typically 45 minutes to 1 hour and 15 minutes at a low temperature of 250°F (120°C). The exact time depends entirely on the steak’s starting temperature and thickness. The final target before searing is an internal temperature of 115-120°F (46-49°C). This slow roast gently cooks the meat edge-to-edge before you sear it.

Never cook a tomahawk by time alone. Always use a reliable meat thermometer. It’s the only way to guarantee your results. The low-and-slow oven phase is the first critical step in the reverse sear method.

What You’ll Need for the Perfect Tomahawk Steak

Gathering your tools and ingredients beforehand makes everything smoother. Here’s your checklist.

The Steak: A tomahawk ribeye, 2 to 2.5 inches thick (about 2.5-3 lbs). Look for good marbling.
Thermometer: An instant-read or leave-in probe thermometer is essential.
Seasonings: Coarse kosher salt, freshly ground black pepper, and optionally garlic powder.
Cooking Fat: A high-smoke-point oil like avocado or grapeseed oil for searing.
Herbs & Butter (Optional): Fresh rosemary, thyme, and unsalted butter for basting.
Equipment: A heavy oven-safe skillet (cast iron is best), a wire rack, and a baking sheet.

Step 1: Preparing Your Tomahawk Steak

Proper prep sets the foundation for flavor and texture. Start this process early.

Bring the Steak to Room Temperature

Take the steak out of the refrigerator at least 1 hour before cooking. Let it sit on the counter. This helps it cook more evenly in the oven. A cold steak straight from the fridge will take much longer and may cook unevenly.

Season Generously

Pat the steak completely dry with paper towels. Moisture is the enemy of a good crust. Season all sides heavily with coarse salt and pepper. Don’t be shy—the thick cut can handle it. The seasoning will penetrate the meat during the slow cook.

Step 2: The Reverse Sear Oven Method

The reverse sear is the best technique for a thick cut like a tomahawk. You cook it low and slow first, then sear it hot and fast at the end. This gives you a perfect edge-to-edge medium rare with a spectacular crust.

Preheat Your Oven: Set your oven to 250°F (120°C). Place a wire rack on a baking sheet.
Insert Thermometer: If using a leave-in probe, insert it into the thickest part of the steak, avoiding the bone.
Slow Roast: Place the steak on the wire rack and put it in the oven. Roast until the internal temperature reaches 115-120°F (46-49°C) for medium rare. This is the “how long tomahawk steak in oven” phase. Plan for 45-75 minutes.
Rest: Once it hits the target temp, remove the steak from the oven and let it rest on the rack for about 15 minutes. This allows the juices to redistribute.

Step 3: Searing for the Perfect Crust

After the oven phase, the steak will look gray and unappealing. That’s normal. The sear transforms it.

Heat Your Skillet: Place your cast iron skillet over high heat for 5 minutes. It needs to be extremely hot.
Add Oil: Add a thin layer of high-smoke-point oil to the skillet.
Sear the Steak: Carefully place the rested steak in the hot skillet. Sear for 60-90 seconds per side, including the edges, until a deep brown crust forms.
Baste (Optional): In the last minute, add butter, garlic, and herbs to the skillet. Tilt the pan and spoon the bubbling butter continuously over the steak.

Step 4: The Final Rest and Serving

This step is non-negotiable. After the intense heat of the sear, the steak needs a final rest.

Transfer the steak to a clean cutting board. Loosely tent it with foil and let it rest for 10 full minutes. This allows the internal temperature to rise a few more degrees to your final target of 130-135°F (54-57°C) for medium rare. It also lets the juices settle so they don’t all run out on the plate.

To serve, slice the meat off the bone. Then, cut it against the grain into thick strips. This ensures each piece is tender and easy to eat. Serve immediately.

Tomahawk Steak Temperature Guide

Use this chart as your reference. Always pull the steak from the oven 10-15 degrees below your desired final doneness, as it will rise during the sear and final rest.

Rare: Oven temp to 105-110°F (41-43°C). Final temp 120-125°F (49-52°C).
Medium Rare: Oven temp to 115-120°F (46-49°C). Final temp 130-135°F (54-57°C).
Medium: Oven temp to 125-130°F (52-54°C). Final temp 140-145°F (60-63°C).
Medium Well: Oven temp to 135-140°F (57-60°C). Final temp 150-155°F (66-68°C).

Common Mistakes to Avoid

Even small errors can affect your steak. Here’s what to watch out for.

Skipping the Thermometer

Guessing doneness on a cut this thick is a recipe for disappointment. A thermometer takes the guesswork out. It’s your most important tool.

Searing Too Early

Do not sear the steak before putting it in the oven. That’s the traditional method, which often leads to a overcooked band of gray meat under the crust. The reverse sear prevents this.

Not Drying the Steak

A wet surface steams instead of sears. Always pat the steak thoroughly dry before seasoning it. This is crucial for that crispy, flavorful crust.

Cutting Immediately

If you slice the steak right after searing, the precious juices will spill out onto the board. Let it rest. The wait is worth it for a juicier result.

Choosing the Right Tomahawk Steak

Starting with a good quality steak makes all the difference. Here’s what to look for at the butcher or store.

Thickness: Aim for at least 2 inches thick. This ensures a dramatic presentation and allows for the reverse sear method to work its magic.
Marbling: Look for fine white streaks of fat within the muscle (marbling). This fat melts during cooking, basting the steak from the inside and adding flavor and tenderness.
Bone: The long, frenched bone should be clean and look impressive. It doesn’t add much flavor during the short cook, but it does affect heat circulation.
Color: The meat should be a bright, cherry-red color. Avoid any steak that looks brown or has a dull appearance.

Sides and Sauces to Complement Your Steak

A great steak deserves great accompaniments. Choose sides that balance the rich, beefy flavor.

Classic Side Dishes

Creamy mashed potatoes or crispy roasted potatoes.
Simple grilled asparagus or roasted broccoli.
A fresh, crisp green salad with a tangy vinaigrette.
Sauteed mushrooms or caramelized onions.

Simple Sauce Ideas

While a good tomahawk needs no sauce, a little on the side can be nice.

Chimichurri: A bright, herby Argentinian sauce made with parsley, garlic, vinegar, and oil.
Compound Butter: Mix softened butter with herbs, garlic, and a pinch of salt. Place a slice on the hot steak.
Red Wine Reduction: Simmer red wine, shallots, and beef broth until it becomes a glossy, rich sauce.

FAQ: Your Tomahawk Steak Questions Answered

Here are answers to some common questions about cooking tomahawk steak.

Can I cook a tomahawk steak from frozen?

It’s not recommended. For the reverse sear to work properly, the steak needs to start at a relatively even temperature. Cooking from frozen will make the timing very difficult and likely result in uneven doneness. Always thaw completely in the fridge first.

What if I don’t have a cast iron skillet?

A heavy stainless steel skillet can work, but cast iron is best for retaining and distributing high heat. If you don’t have an oven-safe skillet, you can finish the steak under your oven’s broiler for a few minutes, watching it closely to avoid burning.

How should I store leftover tomahawk?

Let leftovers cool completely. Store sliced meat in an airtight container in the refrigerator for up to 3 days. Reheat gently in a low oven or skillet to avoid overcooking. Leftover steak is great in salads or sandwiches.

Why is it called a tomahawk steak?

The name comes from it’s long, frenched rib bone, which resembles the handle of a tomahawk axe. It’s essentially a ribeye steak with the bone left extra long for presentation.

Is the reverse sear method better than grilling?

For a cut this thick, the reverse sear in an oven is often more reliable than grilling alone. It gives you superior control over the internal temperature, preventing a burnt exterior and raw interior. You can, however, use a grill for the searing step after the oven for added smoky flavor.

Final Tips for Success

You now know exactly how long tomahawk steak in oven needs and the steps to follow. Remember these final pointers.

Plan ahead. The entire process, from prep to serving, takes about 2 hours. It’s not a quick weeknight meal, but a special occasion centerpiece. Trust the thermometer more than a clock. Every steak and oven is slightly different.

Don’t rush the resting periods. They are as important as the cooking itself for a juicy outcome. Finally, enjoy the process. Cooking a tomahawk steak is a fun and rewarding experience that will impress your guests and satisfy your own taste for a perfectly cooked steak.
