Ingredients

Beef Tenderloin
  • 5-6 pounds beef tenderloin trimmed
  • 1 Tablespoon kosher salt coarse
  • ½ Tablespoon black pepper
  • 3 Tablespoons butter salted
  • 2 Tablespoons Dijon mustard
  • 1 Tablespoon thyme dried
  • 1 teaspoon extra virgin olive oil
  • 8 ounces brown mushrooms halved
Cream Sauce
  • 1 Tablespoon butter salted

  • 1 cup beef broth
  • 1 cup Parmesan Cheese grated
  • kosher salt
  • black pepper

Instructions

Beef Tenderloin
    Cup of Yum
  1. Remove tenderloin from the refrigerator 1 hour before roasting. It has to be at room temperature. Wash and pat dry tenderloin. 
  2. Preheat the oven to 395°F and prepare a baking tray in the middle of the oven.
  3. Season beef tenderloin with salt and pepper. Rub with butter, Dijon mustard and thyme.
  4. 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.
  5. Transfer tenderloin without pan juices in a large enough baking dish.
  6. In the same non-stick skillet, cook mushrooms until half tender. Transfer mushrooms around beef tenderloin in the baking dish with the pan juices.
  7. 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.
  8. Remove roast and let rest for about 15 minutes before slicing.
  9. Serve with the cream sauce.
Cream Sauce
  1. Heat a saucepan over medium heat. Melt butter.
  2. Add onion, garlic and thyme. Stir all together.
  3. Pour milk and beef broth. Bring to a simmer.
  4. 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.
  5. Remove from heat.
  6. Serve with roast beef tenderloin and mashed potato.

Notes

  • Storage
  • 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.
  • 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.
