How To Cook Tomahawk In The Oven

Want to cook a tomahawk steak at home? It’s easier than you think with your oven. Learning how to cook tomahawk in the oven is a fantastic method for achieving a perfect, restaurant-quality steak with a beautiful crust and a juicy, even interior. This guide will walk you through every essential step, from picking the right steak to the final rest.

This method, often called the reverse sear, is ideal for a thick cut like a tomahawk. You slowly bring the steak up to temperature in the oven first, then finish it with a blazing hot sear. This gives you incredible control over the doneness and minimizes the gray band of overcooked meat.

What is a Tomahawk Steak?

A tomahawk steak is a ribeye with a long frenched rib bone left attached. This gives it a dramatic, impressive appearance. The bone isn’t just for show—it adds flavor and helps insulate the meat during cooking, leading to a more tender result. It’s essentially the most spectacular version of a ribeye you can buy.

Why the Oven Method Works So Well

Because of its immense thickness (often 2 inches or more), a tomahawk is challenging to cook evenly on a grill or pan alone. The outside can burn before the inside is ready. The oven’s gentle, surrounding heat cooks the steak evenly from edge to edge. Then, a quick sear at the end creates that essential flavorful crust.

Selecting Your Tomahawk Steak

Start with a good steak, and you’re halfway there. Here’s what to look for:

Thickness: Aim for at least 2 inches thick. This gives you a great contrast between the crust and interior.
Marbling: Look for fine white streaks of fat throughout the meat. This intramuscular fat melts during cooking, basting the steak from the inside for incredible juiciness and flavor.
Grade: USDA Prime is top-tier, but a well-marbled Choice grade can also yield excellent results. Don’t shy away from asking your butcher for advice.
Color: The meat should be a bright, cherry-red color.

Essential Tools You’ll Need

Gathering your tools beforehand makes the process smooth.

A heavy, oven-safe skillet (cast iron is perfect) or a baking sheet with a wire rack.
An instant-read digital meat thermometer. This is non-negotiable for perfect doneness.
Tongs for handling the steak.
Chef’s knife for trimming if needed.
Aluminum foil for resting.

Preparing Your Tomahawk Steak

Preparation is key. Do this about an hour before cooking.

Pat Dry: Unwrap the steak and thoroughly pat it completely dry with paper towels. A dry surface is critical for a good sear.
Season Generously: Season all sides, including the edges, very liberally with coarse kosher salt and freshly ground black pepper. The salt will penetrate and season the meat deeply.
Bring to Room Temp: Let the seasoned steak sit on a rack at room temperature for 45-60 minutes. This promotes even cooking—you don’t want to put a cold steak in the oven.

Should You Use a Rub or Just Salt & Pepper?

For a premium cut like this, simplicity often wins. Salt and pepper truly enhance the beef’s natural flavor. However, if you want a rub, choose one with large granules (like cracked peppercorns, garlic powder, onion powder) that won’t burn in the high heat. Apply it after the steak is dry, before it comes to room temp.

The Step-by-Step Cooking Process

Follow these steps carefully for a flawless tomahawk.

Step 1: Preheat the Oven

Set your oven to a low temperature, between 250°F and 275°F (120°C – 135°C). This low-and-slow approach is the heart of the reverse sear.

Step 2: The Oven Phase (Low & Slow)

Place your steak on a wire rack set inside a baking sheet. This allows air to circulate all around the steak.
Insert your meat thermometer probe into the thickest part of the steak, away from the bone.
Put the steak in the oven and cook until the internal temperature is about 10-15°F below your desired final temperature. For example, for medium-rare (final temp 130°F), pull it at 115°F-120°F. This can take 45 minutes to over an hour, depending on size.

Step 3: The Critical Rest

Once the steak hits that target temperature, take it out of the oven and let it rest on the rack. Tent it loosely with foil. This rest allows the juices, which have been pushed to the center, to redistribute throughout the entire steak. Rest for at least 15 minutes. Don’t skip this!

Step 4: Preheating for the Searing

While the steak rests, get your searing surface screaming hot. Place your cast iron skillet (or a heavy-bottomed pan) over high heat on the stovetop. Let it heat for a good 5 minutes. You want it very hot.

Step 5: The Searing Phase (Hot & Fast)

Add a high-smoke-point oil to the hot pan (like avocado, canola, or grapeseed oil).
Carefully place the rested steak in the pan. It should sizzle violently.
Sear for 60-90 seconds per side, including the edges, until a deep, brown crust forms. Use tongs to hold it upright to sear the fat cap.
For extra flavor, add a few tablespoons of butter, fresh thyme, and garlic cloves to the pan in the last minute. Tilt the pan and baste the steak continuously with the foaming butter.

Step 6: The Final Rest and Serve

Transfer the seared steak to a clean cutting board or platter. Let it rest again, this time for about 5-10 minutes. This final rest ensures all those juices stay in the meat when you slice it. Then, slice against the grain and serve immediately.

Temperature Guide for Doneness

Use this chart, remembering to pull the steak from the oven 10-15°F earlier. Temperatures are final, after searing and resting.

Rare: 120-125°F (49-52°C) – Cool red center.
Medium-Rare: 130-135°F (54-57°C) – Warm red center; ideal for tomahawks.
Medium: 140-145°F (60-63°C) – Warm pink center.
Medium-Well: 150-155°F (65-68°C) – Slightly pink center.

Pro Tips for the Best Results

Dry Brine: For even better flavor and crust, salt the steak the night before and leave it uncovered on a rack in the fridge. This deeply seasons and dries the surface.
Butter Basting: Basting with butter, garlic, and herbs during the sear adds a incredible layer of flavor and richness.
Use the Bone: Don’t forget to sear the bone side and the fat cap. Render that fat for extra crispiness.
Let the Thermometer Guide You: Always trust the internal temperature over a set cooking time. Every steak is a little different.

Common Mistakes to Avoid

Not Drying the Steak: A wet steak will steam instead of sear.
Searing First: Doing the sear first then the oven often leads to a overcooked exterior.
Skipping the First Rest: The rest between the oven and the sear is crucial for the reverse sear method to work properly.
Cutting Immediately: Slicing too soon lets all the flavorful juices run out onto the board.
Using a Thin Pan: A thin pan won’t retain enough heat for a proper sear and can lead to uneven cooking.

Serving Suggestions

A tomahawk is a centerpiece. Serve it simply to let it shine.

Carving: Slice the meat off the bone first, then slice the meat against the grain into thick strips. Serve the bone on the side for gnawing.
Sauces: A classic Béarnaise, a simple chimichurri, or a bold peppercorn sauce are all excellent choices.
Sides: Choose sides that won’t over shadow the steak. Creamed spinach, roasted garlic mashed potatoes, a crisp wedge salad, or grilled asparagus are all perfect.

FAQ Section

How long to cook tomahawk steak in oven?

The time in the low oven isn’t fixed; it depends on size and your oven. It can range from 45 minutes to 1.5 hours. Always use a meat thermometer to know exactly when it’s ready for the sear.

What temperature for tomahawk steak in the oven?

For the reverse sear, use a low oven temperature between 250°F and 275°F (120°C – 135°C). For the final sear, you need the highest heat possible on your stovetop.

Do you sear tomahawk steak before or after oven?

For the reverse sear method, you cook it in the oven first, then sear it afterwards in a very hot pan. This is the best technique for even doneness on a thick cut.

How to cook a tomahawk steak without a cast iron skillet?

If you don’t have cast iron, use the heaviest stainless steel pan you own. Alternatively, you can sear it on a very hot grill after the oven phase. A broiler set to high can also work for the final crust, but watch it closely to prevent burning.

Should you bring tomahawk to room temperature?

Yes, letting it sit out for 45-60 minutes after seasoning is recommended. It helps the steak cook more evenly from edge to center, preventing a cold interior.

Cooking a tomahawk steak in the oven using the reverse sear is a reliable, impressive technique. It takes the guesswork out of cooking a large, expensive cut of meat. By focusing on proper preparation, temperature control, and patience during the rests, you can consistently produce a steak that rivals any steakhouse. Remember, the key tools are a good thermometer and a heavy pan for the sear. Now you have all the knowledge you need to prepare an unforgettable meal.
