I used lean beef tenderloin to make this flavorful roast. It’s perfect for special get-togethers, family celebrations, and festive holiday dinners. Top it with my White Wine Mushroom Sauce for a mouthwatering feast!

If there are any leftovers, I love to make scrumptious sandwiches the next day (as shown in photo, above right).

Ingredients
 

  • 1 whole beef tenderloin, 4 to 5 pounds, tied with string from butcher
  • 2 tablespoons dijon mustard
  • 3 tablespoons peppercorns crushed, or fresh black pepper
  • 1 tablespoon Kosher salt, divided
  • 16 ounces cremini mushrooms halved
  • 1 to 2 tablespoons butter, melted (optional)
  • 1 medium Delicata squash, seeded cut into ¾” rings
  • 1 pound carrots, peeled and cut into 1” chunks
  • 3 medium parsnips, peeled and cut into 1” chunks
  • 1 to 2 red onions, cut into 6 small wedges
  • 3 to 4 fresh thyme sprigs

Instructions
 

  • Preheat oven to 425°F. Liberally coat a large skillet with olive oil spray and warm over medium-high heat. Add the mushrooms and season with ⅛ teaspoon salt and ⅛ teaspoon pepper. Cook 5 minutes or until just tender. Transfer to bottom of roasting pan.
  • Add the beef on top of the mushrooms in roasting pan, and rub with mustard and season generously with crushed peppercorns and 2 teaspoons salt. Drizzle the optional butter over the top of the beef.
  • Toss the cut veggies into the pan evenly around the beef, mist them generously with olive oil spray, season with a sprinkling salt and pepper and nestle in thyme sprigs.
  • Transfer to the oven and roast for 15 minutes at 425°F. Then lower the oven to 375°F, give the veggies a good stir, and cook for about 30-45 minutes (or until the beef reaches an internal temperature of 145°F). If you like your steak rare, while its not recommended for safety reasons, remove when the thickest part hits 125°F. It’s always best to use a meat thermometer.
  • Remove the beef and veggies from the pan to a serving plate and cover with foil for at least 10 minutes before slicing to lock in the juices. Top with White Wine Mushroom Sauce.
