Instructions

  1. Step 1: Preheat smoker to 275°F. Rub 4 lbs bone-in rib roast all over with 2 tbsp kosher salt, 1 tbsp freshly ground black pepper, and 2 tbsp chopped fresh rosemary needles.
  2. Step 2: Toss 6 halved garlic cloves with 2 tbsp olive oil, place them cut side down on a small foil tray or cast iron pan, and position inside the smoker to char for 20 minutes alongside the roast.
  3. Step 3: Place rib roast on the smoker grate and smoke for about 2.5 to 3 hours until internal temperature reaches 130°F for medium-rare.
  4. Step 4: Meanwhile, mash charred garlic cloves into 1/2 cup softened unsalted butter with 1 tsp lemon zest and 1 tbsp chopped thyme leaves until creamy and fragrant.
  5. Step 5: Remove roast from smoker and let rest for 20 minutes. Spread garlic herb butter liberally over the surface before slicing between the bones and serving.
