Onion & Herb Garlic Butter on a Slow-Smoked Reverse-Seared Tomahawk

To make the onion & herb garlic butter: combine diced red onion, juice of 1/2 lemon, 3 garlic cloves, 1 tsp Thyme Salt, 1/2 tsp Rosemary, and 1 stick butter. For the steak: season with Birch Smoked Salt. To nail a medium rare cook on the steak, smoke until internal temp reaches 110°F then sear until temp reaches 125-128°F. Remove and rest the steak, topping with the prepared garlic butter.
