- 1 bone-in beef tomahawk steak, approx. 32 oz (900 g) - 2 tsp (10 g) kosher salt - 1 tsp (5 g) freshly ground black pepper - 2 tbsp (30 ml) neutral oil (for searing) - 4 tbsp (60 g) unsalted butter, softened - 2 tbsp (8 g) fresh parsley, finely chopped - 1 tbsp (6 g) fresh thyme leaves, finely chopped - 2 cloves garlic, minced - 12 oz (340 g) fingerling potatoes, halved lengthwise - 2 tbsp (30 ml) olive oil (for potatoes) - Salt and pepper to taste for potatoes
1. Preheat oven to 225°F (110°C). Season the tomahawk generously with 2 tsp kosher salt and 1 tsp black pepper; place on a rack over a baking sheet. 2. Roast tomahawk in the oven until internal temperature reaches about 110°F (43°C) for medium-rare final result, about 30–45 minutes depending on thickness. 3. While steak roasts, toss fingerling potatoes with 2 tbsp olive oil, salt, and pepper; spread on a baking sheet and roast at 400°F (200°C) for 25–30 minutes until golden and tender. 4. Combine softened butter, parsley, thyme, and minced garlic to make garlic-herb butter; refrigerate until ready. 5. Heat 2 tbsp neutral oil in a large cast-iron skillet over very high heat until just smoking. Sear the tomahawk 1–2 minutes per side and 30–60 seconds on the edges to develop a deep crust. 6. Remove steak, top with garlic-herb butter, and rest 10 minutes before slicing; serve with roasted fingerling potatoes.
