How to Make Mushroom and Leek Stuffed Beef Tenderloin with Root Vegetables

Pre-Steps:

1. Place the top oven rack in the center position and pre-heat the oven to 400°F. Prepare the vegetables and garlic.

Make the Mushroom and Leek Stuffing

2. Heat two tablespoons olive oil in a large, high-sided skillet over medium heat. Add the leeks, mushrooms, and garlic. Season with salt and black pepper, to taste, and stir to combine.

3. Cook, stirring occasionally, until the vegetables develop some color and most of the water from the mushrooms evaporates, approximately 8-10 minutes.

4. Add the spinach and fresh herbs. Continue cooking until the spinach wilts, approximately 1-2 minutes. Remove from heat and set aside.

Butterfly and prepare the beef tenderloin

5. Place the butterflied beef tenderloin between two sheets of plastic wrap or wax paper and gently pound with a meat mallet or rolling pin to a ½-inch even thickness. Brush the surface of the beef with the remaining olive oil and generously season with salt and black pepper, to taste.

Use a kitchen mallet to tenderize and flatten the beef tenderloin.

6. Stir the Parmesan cheese into the mushroom-spinach mixture until combined. Evenly spread the mixture over the beef tenderloin, leaving a small border (½-1 inch) around the edges.

Spread the stuffing mixture over the flattened beef tenderloin.

7. Carefully roll up the tenderloin like a jelly roll and secure with kitchen twine. Season the outside of the beef with additional salt and black pepper, as desired, and place in the center of a roasting pan lined with the sliced red onions.

Rest the stuffed beef tenderloin on a bed of onions in the roasting pan.

Roast the beef tenderloin with the root vegetables

8. Nestle the shallots and carrots around the beef and tuck in the fresh thyme sprigs. Add the beef broth and place in the pre-heated oven to roast until the beef reads between 125°F-130°F* for medium-rare on an instant read thermometer, approximately 35-40 minutes. (The temperature will rise another 5-10 degrees while resting).

Add the root vegetables and thyme sprigs to the roasting pan.

9. Transfer the beef tenderloin to a serving platter and cover loosely with foil to keep warm. If necessary, return the vegetables to the oven for another 10-15 minutes, or until fork tender.

10. Transfer the veggies to the serving platter and pour the pan juices into a medium saucepan. Place over medium-high heat and reduce for approximately 5 minutes, stirring occasionally. Add the butter and stir to emulsify the butter and thicken the sauce.

11. Carve the stuffed tenderloin and serve immediately with the roasted vegetables and pan sauce. Enjoy!
