How to Make Beef Tenderloin Roast With Mushroom Sauce
- Preheat oven to 450°F (232°C).
- Pat the 2-3 lb beef tenderloin completely dry with paper towels and place it on a wire rack set inside a roasting pan.
- Season the tenderloin generously with 2 tsp salt, 1 tsp black pepper, and 4 cloves minced garlic.
- Roast for 35 minutes, or until a meat thermometer inserted into the thickest part registers 125°F (52°C) for medium-rare.
- Increase the temperature to 130°F (54°C) for medium. Cook longer if you prefer a less rare roast, checking temperature regularly.
- Remove the roast from the oven and let it rest, loosely tented with foil, for at least 15 minutes before slicing.
- While the beef rests, prepare the sauce: Melt 2 tbsp butter in a medium skillet over medium heat.
- Add 1 medium onion, finely chopped, and sauté for 5 minutes until softened.
- Add 8 oz cremini mushrooms, sliced, and cook for another 5-7 minutes, or until browned and tender.
- Stir in 2 tbsp all-purpose flour and cook for 1 minute, stirring constantly.
- Gradually whisk in 1 cup beef broth, ensuring no lumps form.
- Add 1/2 cup dry red wine (optional), 1 tbsp Dijon mustard, and 1 tsp fresh thyme leaves.
- Bring to a simmer, reduce heat to low, and cook for 5-10 minutes, or until the sauce has thickened to your desired consistency.
- Season the sauce with salt and pepper to taste.
- Slice the rested beef tenderloin and serve it with the rich mushroom sauce.
