Instructions

  1. Step 1: Preheat oven to 400°F. Place 1 (1.5 lb) beef tenderloin on a wire rack set over a baking sheet. Brush with 2 tablespoons olive oil and sprinkle with 1 tablespoon chopped fresh rosemary, 1 teaspoon chopped fresh thyme, 1/2 teaspoon salt, and 1/4 teaspoon black pepper.
  2. Step 2: Wrap 8 slices of bacon around the tenderloin, securing with toothpicks if necessary. Place the wrapped tenderloin back on the wire rack and roast in the preheated oven for 40-45 minutes until the internal temperature reaches 130°F for medium-rare.
  3. Step 3: Remove from oven, let rest for 10 minutes, then remove toothpicks and slice. Serve with any pan drippings.
