Ingredients
- 1 whole beef tenderloin (about 4 pounds), trimmed and tied
- 2 tablespoons olive oil
- 3 cloves garlic, minced
- 2 teaspoons salt
- 1 teaspoon black pepper
- 1 tablespoon fresh rosemary, chopped
- 1 tablespoon fresh thyme, chopped
- 1 tablespoon Dijon mustard
Instructions
- Step 1: Preheat your oven to 425°F (220°C). Place the trimmed beef tenderloin on a baking sheet.
- Step 2: In a small bowl, combine olive oil, minced garlic, salt, pepper, rosemary, thyme, and Dijon mustard. Rub the mixture evenly all over the tenderloin.
- Step 3: Roast the beef in the preheated oven for about 40 minutes, or until it reaches your desired doneness (135°F for medium-rare).
- Step 4: Remove the beef from the oven and let it rest for at least 10 minutes before slicing. This resting time allows the juices to redistribute for a juicy, flavorful roast.
Tips & Variations
- For an extra layer of flavor, marinate the tenderloin in the herb mixture for a few hours or overnight before roasting.
- If you prefer a crustier exterior, sear the tenderloin in a hot pan for 2-3 minutes per side before roasting.
- Substitute fresh herbs with 1 teaspoon each of dried rosemary and thyme if fresh are not available.
Storage
Store leftover roast beef in an airtight container in the refrigerator for up to 3 days. To reheat, warm gently in the oven at 300°F (150°C) wrapped in foil to retain moisture and prevent drying out.
