There are a few steps to this recipe, but not that many. They’re also all very easy.
Step 1: Marinade the Steak
Combine the buttermilk, crushed garlic, rosemary, coffee beans, peppercorns, Worcestershire sauce, and bay leaves in a bowl. Then, place the steak in a resealable bag and pour the marinade over it. Refrigerate for a minimum of 6 hours.
Step 2: Preheat the Smoker
Preheat the smoker to 180 degrees with the lid closed for 20 minutes. Remove the steak from the refrigerator and let it come to room temperature while the smoker preheats.
Step 3: Season the Steak
Remove the steak from the marinade and place it on a wooden cutting board. Then, pat it dry and season it on both sides with sea salt flakes and cracked black pepper.
Step 4: Smoke the Steak
Place the steak directly on the grill grate and smoke for an hour.
Step 5: Finish in the Skillet
After an hour, remove the steak from the smoker, place a cast iron skillet in the smoker, and increase the heat to 450 degrees.
Then, add thinly sliced shallots to the top of the steak. Add butter to the skillet when it reaches temperature and place the steak on top of the butter. Add the rosemary along the sides of the steak, baste it with melted butter, and close the smoker lid. Cook for 10 more minutes.
Step 6: Let the Steak Rest
Remove the skillet and baste the steak with butter several times. Then, remove the steak and let it rest on a wooden cutting board for about 10 minutes as it continues to cook to an internal temperature of 130 degrees.
Step 7: Slice and Serve
Thinly slice the steak on the diagonal against the grain. Serve with your favorite veggies or sides.
Hint: Always be sure your grill grates are thoroughly cleaned and greased so the meat doesn’t stick.
