Ingredients

Instructions

  1. Step 1: Pat dry 4 beef tenderloin medallions and season both sides evenly with 1 tsp salt and 1 tsp black pepper.
  2. Step 2: Heat 2 tbsp olive oil in a large skillet over medium-high heat until shimmering. Add the medallions and sear for 3-4 minutes on each side until a deep brown crust forms and internal temperature reaches 130°F for medium-rare. Remove medallions to a warm plate and tent with foil.
  3. Step 3: Reduce heat to medium and add 2 tbsp unsalted butter and 2 tbsp finely chopped shallots to the skillet. Sauté shallots for 2 minutes until softened and fragrant.
  4. Step 4: Stir in 2 tbsp Dijon mustard and 1/4 cup beef broth, scraping the browned bits from the pan. Let the mixture simmer for 1-2 minutes until slightly reduced.
  5. Step 5: Pour in 1/2 cup heavy cream, stirring constantly, and cook for an additional 2-3 minutes until the sauce thickens enough to coat the back of a spoon.
  6. Step 6: Remove from heat, stir in 1 tbsp chopped fresh parsley, and spoon the mustard cream sauce over the beef medallions before serving.
