Ingredients

  • 1 (5 lb) beef tenderloin, fat trimmed and patted dry
  • Salt and pepper to taste
  • 1/4 cup plus 1 tablespoon butter, softened
  • 3 cloves garlic, minced (plus 3 whole cloves for roasting)
  • 2 tablespoons minced fresh rosemary (plus a couple sprigs for roasting)
  • 1 tablespoon olive oil
  • 1 cup red wine
  • 1/2 cup beef stock
  • 1 tablespoon balsamic vinegar

Instructions

  • Preheat oven to 400F. Season beef tenderloin all over with salt and pepper. Set aside.
  • In a small bowl, combine 1/4 cup butter, minced garlic, and rosemary. Set aside.
  • Heat a large cast iron skillet over medium high heat. Add 1 tablespoon butter and oil and swirl pan until melted. Add beef tenderloin to pan and sear all sides until golden brown. Remove tenderloin from heat and place in a baking dish. Brush with half of garlic rosemary butter. Arrange garlic cloves and rosemary around tenderloin. (set cast iron pan aside for later)
  • Bake tenderloin at 400F 20-25 minutes until tenderloin reaches an internal temp of 120-125. Remove from pan to a cutting board and brush with remaining butter. Cover loosely with foil and let rest 10 minutes.
  • While tenderloin is resting, drain drippings from cast iron pan, reserving 1 tablespoon. Heat pan over medium-high heat and add red wine, stock, and vinegar. Bring to a simmer, then reduce heat to medium-low and let simmer until reduced and thickened.
  • Slice rested beef tenderloin and serve warm with red wine sauce. Serve immediately and enjoy!
