Ingredients

Instructions

  1. Step 1: Season 4 beef tenderloin medallions (6 oz each) evenly with 1 tsp kosher salt and 1 tsp freshly ground black pepper on both sides.
  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 per side until a deep brown crust forms and the internal temperature reaches 130°F for medium-rare.
  3. Step 3: Remove the medallions from the skillet and tent with foil to rest.
  4. Step 4: In the same skillet, reduce heat to medium and add 2 minced shallots. Sauté for 2 minutes until softened and fragrant.
  5. Step 5: Add 1/4 cup beef broth and scrape the browned bits from the pan, simmering for 2 minutes until slightly reduced.
  6. Step 6: Stir in 2 tbsp Dijon mustard and 1/2 cup heavy cream, cooking gently for 3-4 minutes until the sauce thickens and coats the back of a spoon.
  7. Step 7: Whisk in 2 tbsp butter and 1 tsp chopped fresh thyme for richness and aroma.
  8. Step 8: Plate the beef medallions and spoon the mustard cream sauce over the top before serving.
