Ingredients

• 4 pieces (4-6 oz each) beef tenderloin medallions
• 2 tablespoons olive oil
• 1 tablespoon unsalted butter
• 2 tablespoons shallots, minced
• 2 cloves garlic, minced
• 1 cup cremini mushrooms, sliced
• 1 tablespoon Dijon mustard
• 2 teaspoons Worcestershire sauce
• 1 cup low-sodium beef broth
• 2 tablespoons heavy cream
• 1 tablespoon fresh parsley, chopped
• 0.5 teaspoon salt
• 0.5 teaspoon black pepper, freshly ground

Directions

Step 1

Season the beef medallions on both sides with salt and freshly ground black pepper.

Step 2

Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the beef medallions and sear for 3-4 minutes per side, or until cooked to your desired doneness (130°F for medium-rare). Remove the steak from the skillet and set aside, tenting with foil to keep warm.

Step 3

Reduce the heat to medium. Add the remaining 1 tablespoon of olive oil and 1 tablespoon of unsalted butter to the skillet.

Step 4

Stir in the minced shallots and garlic, cooking for 1-2 minutes until fragrant and softened.

Step 5

Add the sliced cremini mushrooms to the skillet. Cook for 4-5 minutes, stirring occasionally, until the mushrooms are tender and golden brown.

Step 6

Stir in the Dijon mustard and Worcestershire sauce, mixing well to coat the mushrooms.

Step 7

Pour in the beef broth, scraping the bottom of the skillet to deglaze and incorporate any browned bits from cooking the steak. Simmer for 3-4 minutes to reduce slightly.

Step 8

Stir in the heavy cream and cook for another 1-2 minutes, allowing the sauce to thicken slightly.

Step 9

Return the beef medallions to the skillet, spooning the sauce over the top to heat them through for 1-2 minutes.

Step 10

Garnish with fresh parsley before serving. Serve immediately with your favorite low-carb side dish, such as steamed asparagus or cauliflower mash.
