Ingredients
Beef Tenderloin
- 5-6 pounds beef tenderloin, trimmed
- 1 Tablespoon coarse kosher salt
- ½ Tablespoon black pepper
- 3 Tablespoons salted butter
- 2 Tablespoons Dijon mustard
- 1 Tablespoon dried thyme
- 1 teaspoon extra virgin olive oil
- 8 ounces brown mushrooms, halved
Cream Sauce
- 1 Tablespoon salted butter
- ½ teaspoon onion powder
- ½ teaspoon garlic powder
- ½ teaspoon dried thyme
- 2 cups whole milk
- 1 cup beef broth
- 1 cup grated parmesan
- Kosher salt and black pepper
Instructions
Beef Tenderloin
- Remove tenderloin from the refrigerator 1 hour before roasting. It has to be at room temperature. Wash and pat dry tenderloin.
- Preheat the oven to 395°F and prepare a baking tray in the middle of the oven.
- Season beef tenderloin with salt and pepper. Rub with butter, Dijon mustard and thyme.
- Heat a non-stick skillet over high heat with oil. Oil must be smoked hot to sear the tenderloin. Sear all 4 sides until browned.
- Transfer tenderloin without pan juices in a large enough baking dish.
- In the same non-stick skillet, cook mushrooms until half tender. Transfer mushrooms around beef tenderloin in the baking dish with the pan juices.
- Cook in the oven for about 25 minutes or to your favorite doneness of roast. For medium rare, an instant-read thermometer inserted in the roast must register 120 - 125°F.
- Remove roast and let rest for about 15 minutes before slicing.
- Serve with the cream sauce.
Cream Sauce
- Heat a saucepan over medium heat. Melt butter.
- Add onion, garlic and thyme. Stir all together.
- Pour milk and beef broth. Bring to a simmer.
- Turn to low-medium. Add parmesan little by little and stir with a wooden spoon. Don’t leave the cream sauce or it will boil too much.
- Remove from heat.
- Serve with roast beef tenderloin and mashed potato.
Notes
Storage
- Store: Allow the beef roast to cool down completely, then place it in an airtight container in the refrigerator for up to 2 days. Reheat in the microwave on low-medium heat until warmed through to enjoy it again, or use it in other beef recipes.
- Freeze: The best way to freeze roasted beef is by dividing it into individual portions first. Place the portions in ziplock bags or airtight containers to freeze for up to 3 months. You can alternatively wrap it in aluminum foil if you have it instead. Defrost completely before reheating.
