Remove the tomahawk steak from the refrigerator and let it come to room temperature.
Preheat your grill or oven to 450°F (232°C).
Generously season both sides of the steak with salt and black pepper.
Heat olive oil in a cast-iron skillet over medium-high heat.
Sear the steak for about 3-4 minutes on each side until a crust forms.
Add butter, garlic, and herbs to the skillet, basting the steak with the melted butter.
Transfer the skillet to the preheated oven.
Cook until the steak reaches your preferred internal temperature.
Remove from the oven and let it rest for 10-15 minutes.
Slice and serve, garnished with fresh herbs.
