Ingredients

• 3 pounds Top sirloin roast
• 2 tablespoons Ancho chili powder
• 1 tablespoon Smoked paprika
• 1 teaspoon Ground cumin
• 2 teaspoons Unsweetened cocoa powder
• 4 cloves Garlic cloves, minced
• 2 tablespoons Olive oil
• 2 tablespoons Fresh lime juice
• 1 tablespoon Dark brown sugar
• 2 teaspoons Salt
• 1 teaspoon Freshly ground black pepper
• 1 cup Beef stock
• 1 tablespoon Cornstarch
• 2 tablespoons Water
• 2 tablespoons Fresh cilantro, chopped (for garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

In a small bowl, mix together the ancho chili powder, smoked paprika, ground cumin, cocoa powder, minced garlic, olive oil, lime juice, dark brown sugar, salt, and black pepper to form a thick paste.

Step 3

Pat the sirloin roast dry with paper towels and rub the spice paste evenly over the entire surface of the meat. Let it rest for 15 minutes to marinate.

Step 4

In a large oven-safe skillet or roasting pan, heat a drizzle of olive oil over medium-high heat. Sear the roast on all sides until a crust forms, about 2-3 minutes per side.

Step 5

Remove the skillet from heat and pour the beef stock around the roast. Transfer the skillet to the preheated oven.

Step 6

Roast the beef for approximately 60-75 minutes, or until the internal temperature registers 130°F (54°C) for medium-rare or 140°F (60°C) for medium.

Step 7

Remove the roast from the oven and transfer it to a cutting board. Loosely cover with foil and allow it to rest for 10-15 minutes.

Step 8

While the meat rests, place the skillet with the beef stock over medium heat. In a small bowl, whisk the cornstarch with water to create a slurry. Stir the slurry into the skillet and cook until the sauce thickens, about 2-3 minutes.

Step 9

Slice the roast beef thinly against the grain and drizzle with the prepared sauce.

Step 10

Garnish with chopped cilantro and serve immediately.
