The Cowboy’s Tomahawk with Bone-Marrow Butter
A thick-cut, flame-seared ribeye crowned with a decadent, melting marrow compound butter.
Headnote
There is no steak more theatrical or primal than the tomahawk. With its long, frenched bone acting as a handle, it demands a certain level of respect at the grill. This isn't just dinner; it’s an event. I first mastered this over a fire pit in the high desert, where the scent of rendering beef fat and mesquite smoke seemed to settle right into my bones. The secret to a steak this thick is the reverse sear—starting low and slow to ensure the edge-to-edge pink internal color that every carnivore craves.
The real magic, however, lies in the bone-marrow butter. While the steak rests, you’ll whip up a compound butter that uses roasted marrow as the primary fat source. As it hits the hot steak, it creates a rich, umami-laden lacquer that no store-bought sauce can touch. One critical tip: use an instant-read thermometer. When dealing with a three-pound piece of meat, "guessing" is the quickest way to ruin a very expensive evening.
Prep time: 20 min (plus 2 hours salting) Cook time: 60 min Total time: 80 min (plus resting) Yield: 2–3 servings Difficulty: Medium
Ingredients
For the Tomahawk: 1 tomahawk ribeye steak (approx. 3 lbs, 2.5 inches thick) 2 tbsp coarse kosher salt 1 tbsp cracked black pepper 2 tbsp beef tallow (or high-smoke point oil)
For the Bone-Marrow Butter: 2 beef marrow bones (3–4 inches long, canoe-cut) 4 tbsp unsalted butter, softened to room temperature 2 cloves garlic, minced 1 tsp flaky sea salt 1 tsp fresh thyme leaves, stripped from the stem
Method
- Salt the steak heavily on all sides, including the fat cap, at least 2 hours before cooking (or up to 24 hours in the fridge).
- Preheat your oven to 250°F (120°C) and place the marrow bones on a small baking sheet.
- Roast the marrow bones for 15 minutes until the marrow is bubbling and softened but not completely melted away.
- Scoop the warm marrow into a small bowl and whisk it vigorously with the softened butter, garlic, sea salt, and thyme until light and aerated.
- Set the marrow butter aside at room temperature to keep it spreadable.
- Place the salted steak on a wire rack set over a rimmed baking sheet.
- Roast the steak in the oven until the internal temperature reaches 115°F (46°C) for medium-rare, which typically takes 45–60 minutes.
- Remove the steak from the oven and let it rest on a cutting board for 10 minutes (do not skip this, or the juices will flee during the sear).
- Heat a heavy cast-iron skillet or griddle over high heat until the tallow begins to smoke and shimmer.
- Sear the steak for 60–90 seconds per side until a deep, dark mahogany crust forms and the fat edges are crisp.
- Use tongs to hold the steak upright and sear the thick fat cap for 30 seconds until it rendered and browned.
- Remove the steak to a board and immediately crown it with a massive dollop of the bone-marrow butter.
- Let the steak rest for another 5 minutes, allowing the butter to pool and glaze the meat, before carving against the grain.
Variations
The Smoked Cowboy: If you have a pellet grill or smoker, replace the oven step with a low-temp smoke at 225°F (107°C) using hickory or oak pellets until you hit the 115°F internal mark. Blue Cheese Infusion: Fold 2 tablespoons of high-quality gorgonzola crumbles into the bone-marrow butter for a sharper, more pungent finish. Peppercorn Crust: Before the final sear, press additional coarsely cracked peppercorns into the surface of the meat to create a "steak au poivre" style crust.
Storage & Reheating
Store leftover steak in an airtight glass container in the refrigerator for up to 3 days. To reheat without overcooking, place the steak in a 250°F (120°C) oven until it reaches an internal temperature of 110°F, then flash-sear it in a hot pan for 30 seconds. The leftover marrow butter can be rolled in parchment paper, chilled, and sliced for use on future steaks or even eggs; it keeps for two weeks in the fridge.
Pairing Suggestion
Serve this alongside a cold, crisp glass of sparkling water or a heavy-bodied Cabernet Sauvignon to cut through the intense richness of the marrow fat.
