Ingredients:
- 2.5 lb (1.1 kg) beef tri-tip roast, trimmed to a 1/4-inch fat cap
- 2 tsp (12 g) kosher salt
- 1 tsp (2 g) coarsely ground black pepper
- 1 tsp (3 g) garlic powder
- 1 tsp (2 g) smoked paprika
- 1 tsp (4 g) packed brown sugar
- 1/2 tsp (1 g) dried thyme
- 1/2 tsp (1.5 g) onion powder
- 1/4 tsp (0.5 g) cayenne pepper
- 1 tbsp (15 ml) avocado or olive oil
- 2 tbsp (28 g) unsalted butter
- 3 cloves garlic, smashed
- 2 sprigs fresh rosemary
Instructions:
- Pat the tri-tip completely dry with paper towels.
- Rub the roast all over with the oil.
- Mix the salt, black pepper, garlic powder, smoked paprika, brown sugar, thyme, onion powder and cayenne. Coat the roast evenly with the rub, with no bare patches.
- Optional: refrigerate the roast uncovered for up to 1 hour, then bring it to room temperature for 15 minutes before cooking.
- Preheat the oven to 425°F (220°C).
- Heat a 12-inch oven-safe skillet over medium-high until hot, about 2 minutes.
- Place the roast fat side down in the skillet and sear for 4 minutes, until the surface is deep mahogany with no pale patches.
- Sear the remaining sides, including the ends, for 2 to 3 minutes each.
- Reduce the heat to medium. Add the butter, garlic cloves and rosemary. Tilt the pan and spoon the foaming butter over the meat for about 1 minute, until the garlic smells toasty and nutty, not bitter.
- Transfer the skillet to the oven and roast for 15 to 25 minutes, until the thickest part reaches 145°F (63°C) on an instant-read thermometer, keeping the probe away from the fat cap. The center should be rosy pink.
- Transfer the roast to a board, tent loosely with foil and rest for 10 minutes.
- Find the corner where the two grain directions meet, then slice across the grain into 1/4-inch pieces.
- Spoon the pan juices over the slices and serve.
