Ingredients

  • For the Bison:
  • 1 tablespoon brown sugar
  • Kosher salt and freshly ground black pepper
  • 2 tablespoons ancho chili powder
  • 1 teaspoon cumin
  • 1/2 teaspoon Mexican oregano
  • 1/2 teaspoon ground coriander
  • 1 center-cut bison tenderloin, trimmed and tied for roasting (about 2 pounds, see note above)
  • For the Sauce:
  • 1 bunch fresh cilantro leaves and fine stems (about 2 loosely packed cups)
  • 2 medium cloves garlic, roughly chopped
  • 1/2 teaspoon red pepper flakes
  • 1 tablespoon red wine vinegar
  • 1/4 cup extra-virgin olive oil
  • 2 tablespoons canola oil

Procedures

  1. 1

    Combine sugar, 1 tablespoon kosher salt, 1 teaspoon freshly ground black pepper, chili powder, cumin, oregano, and coriander in a small bowl and mix with fingers until homogenous. Rub evenly over entire surface of tenderloin. Transfer to a wire rack, refrigerate, and let rest for at least 45 minutes and up to overnight.

  2. 2

    Meanwhile, combine cilantro, garlic, red pepper flakes, vinegar, and olive oil in the bowl of a food processor or blender. Process until a rough sauce is formed, about 20 seconds. Season to taste with salt and pepper.

  3. 3

    When ready to cook, adjust oven rack to center position and preheat oven to 275°F. Heat oil in a large cast iron or stainless steel skillet over medium-high heat until shimmering. Add tenderloin and cook, turning occasionally, until browned on all sides, about 4 minutes. Transfer tenderloin to a wire rack set in a rimmed baking sheet and transfer to oven. Roast until an instant read thermometer inserted into center of roast registers 125°F for medium rare or 135°F for medium, about 20 minutes. Remove from oven and let rest 5 minutes before carving and serving with sauce.
