# The Cowboy’s Tomahawk with Bone-Marrow Butter
*A thick-cut, flame-seared ribeye crowned with umami-rich whipped marrow*

## Headnote
There is no steak more theatrical than a tomahawk, but its beauty isn’t just in the long, frenched bone; it’s in the thickness. Because a tomahawk is essentially a double-cut ribeye, you cannot cook it like a standard steak. If you throw this straight onto a screaming hot grill, you will have a charred exterior and a blue, cold center. The secret is the reverse sear: we bring the meat up to temperature slowly in the oven (or the cool side of the grill) before finishing it with a crust-forming sear.

The bone-marrow butter is what elevates this from a backyard barbecue staple to a masterpiece. When that compound butter hits the resting steak, it melts into the crannies of the seared fat, creating a silken, nutty sauce that makes standard garlic butter feel pedestrian. I first served this at a summer solstice bonfire, and now, my guests refuse to accept a "normal" steak without the marrow. 

One critical tip: Use a meat thermometer. With a cut this expensive, guessing by "feel" or time is a gamble you don't want to take. Pull the meat when the internal temperature hits 115°F (46°C) for a perfect medium-rare finish after the sear.

**Prep time:** 20 min (plus 1 hour tempering)
**Cook time:** 60 min
**Total time:** 1 hr 20 min
**Yield:** 2–3 servings
**Difficulty:** Medium

## Ingredients
**For the Bone-Marrow Butter:**
* 2–3 beef marrow bones (about 4 inches long), split lengthwise
* 1/2 cup unsalted grass-fed butter, softened to room temperature
* 1 tsp coarse sea salt
* 1/2 tsp freshly cracked black pepper
* 1 tbsp fresh chives, finely snipped

**For the Tomahawk:**
* 1 tomahawk ribeye (approx. 2.5–3 lbs and 2 inches thick)
* 2 tbsp avocado oil or beef tallow (high smoke point is essential)
* 3 tbsp kosher salt
* 2 tbsp coarse black pepper

## Method
1. Remove the tomahawk from the refrigerator at least one hour before cooking to allow it to reach room temperature. 
2. Preheat your oven (or smoker) to 225°F (107°C).
3. Roast the split marrow bones on a small baking sheet for 15–20 minutes until the marrow is bubbling and softened but not completely melted away.
4. Scoop the warm marrow out of the bones into a small bowl and let it cool for 5 minutes.
5. Combine the softened butter, roasted marrow, sea salt, pepper, and chives in a bowl, whipping with a fork until smooth and unified.
6. Pat the tomahawk completely dry on all sides using paper towels; moisture is the enemy of a good crust.
7. Season the steak aggressively with kosher salt and coarse pepper, pressing the seasoning into the meat with your palms until every surface is coated.
8. Place the steak on a wire rack set over a baking sheet and slide it into the oven.
9. Cook until the internal temperature reaches 115°F (46°C), which typically takes 45–60 minutes depending on thickness.
10. Heat a heavy cast-iron skillet (or your grill) over high heat until the oil or tallow begins to smoke lightly.
11. Sear the steak for 2 minutes per side, using tongs to hold the steak upright to render the thick fat cap along the edge.
12. Remove the steak to a wooden cutting board and immediately place a massive dollop of the bone-marrow butter on top.
13. Let the meat rest for at least 10 minutes, allowing the juices to redistribute and the butter to create a glossy glaze.
14. Slice against the grain, perpendicular to the bone, and pour any accumulated juices from the board back over the meat.

## Variations
**The Smokehouse Version**: Use a pellet grill or smoker with hickory or mesquite wood for the initial 225°F cook to infuse the fat with a deep, campfire aroma.
**The Blue Cheese Funk**: Fold 2 tablespoons of high-quality gorgonzola dolce into the bone-marrow butter for an extra layer of savory, pungent richness.
**The Herb Infusion**: If chives aren't available, swap them for finely minced rosemary and thyme to lean into a more "prime rib" flavor profile.

## Storage & Reheating
Store leftover steak in an airtight glass container in the fridge for up to 3 days. To reheat without overcooking, place the steak in a 250°F (120°C) oven until just warm to the touch (about 10 minutes) and top with a fresh slice of the reserved marrow butter. Do not microwave, as it will turn the delicate fat rubbery.

## Pairing Suggestion
Serve this alongside a chilled glass of bold, tannin-heavy Cabernet Sauvignon to cut through the intense richness of the marrow.
