Why it works
Tri-tip's dense marbling and moderate size allow it to absorb smoke flavor without drying out when held at steady 225°F. The coffee-cocoa rub creates a flavorful bark while cocoa adds subtle sweetness and complexity. Pan sauce made from drippings adds richness and moisture to each slice.
This cook is built for intermediate pitmasters running a smoker setup, but the real win is that the method stays adaptable if your fire drifts or your timing gets crowded.
- Combine coffee grounds, cocoa powder, brown sugar, kosher salt, black pepper, garlic powder, and smoked paprika in a small bowl. Mix thoroughly to break up any cocoa lumps.
- Pat tri-tip dry with paper towels. Rub oil lightly over the entire surface, then coat generously with the coffee-cocoa mixture, pressing gently so it adheres. Let sit at room temperature for 30 minutes while you prepare the smoker.
- Preheat smoker to 225°F using oak or hickory wood. Aim for thin blue smoke. Position a drip pan filled with water below the grate to catch drippings and maintain moisture.
- Place seasoned tri-tip on the grate, fat-side up. Smoke for approximately 4 to 5 hours, until internal temperature reaches 130°F (medium-rare) when measured in the thickest part. Plan for roughly 60 minutes per pound, though timing varies by smoker.
- Remove tri-tip from smoker and place on a cutting board. Tent loosely with foil and rest for 15 minutes. This allows carryover cooking and helps retain juices during slicing.
- Pour drippings from the drip pan into a small saucepan. Add minced shallot and place over medium heat. Pour in beef stock and simmer for 3 minutes, scraping up any browned bits. Whisk in butter until emulsified. Season with salt and pepper to taste.
- Slice tri-tip against the grain into quarter-inch pieces. Arrange on a serving platter and drizzle with warm pan sauce. Serve any remaining sauce on the side.
