Ingredients

Steak

  • 2 filet mignon steaks (6–8 oz each)
  • 1 tbsp olive oil
  • 1 tsp salt
  • 0.5 tsp black pepper

Sauce

  • 2 tbsp unsalted butter
  • 1 shallot, finely chopped
  • 1.5 cups mushrooms, sliced
  • 2 garlic cloves, minced
  • 0.75 cup heavy cream
  • 0.5 cup beef broth
  • 1 tsp fresh thyme leaves

Instructions

  1. Rest and Season: Let the filet mignon rest at room temperature for about 20 minutes to ensure even cooking. Generously season both sides of the steaks with salt and black pepper.
  2. Preheat Skillet and Add Oil: Heat a heavy skillet over medium-high heat until hot. Add 1 tablespoon of olive oil and swirl to coat the pan evenly.
  3. Sear Steaks: Place the steaks in the skillet and sear for 3–4 minutes on each side until a golden-brown crust forms. Cook to your desired doneness, bearing in mind that thinner steaks cook faster.
  4. Rest Steaks: Remove the steaks from the skillet and transfer to a plate. Let them rest for several minutes to allow the juices to redistribute.
  5. Sauté Shallots: In the same skillet, melt 2 tablespoons of unsalted butter over medium heat. Add the finely chopped shallots and sauté until soft and translucent, about 2 minutes.
  6. Cook Mushrooms: Add the sliced mushrooms to the skillet. Cook until they release their moisture and start to brown, approximately 5–7 minutes.
  7. Add Garlic and Thyme: Stir in the minced garlic and fresh thyme leaves. Cook for about 1 minute until fragrant.
  8. Deglaze with Broth: Pour in 0.5 cup of beef broth, scraping the bottom of the pan to loosen browned bits. Let the broth simmer until it has reduced slightly, about 3–4 minutes.
  9. Add Cream and Thicken Sauce: Stir in 0.75 cup heavy cream and let the sauce simmer gently until it thickens, around 5 minutes, stirring occasionally.
  10. Finish and Serve: Taste the sauce and adjust seasoning if needed. Spoon the creamy mushroom shallot sauce generously over the rested filet mignon steaks and serve immediately.

Notes

  • Letting the steaks rest before cooking helps them cook evenly.
  • Allowing the steaks to rest after searing ensures juicy, tender meat.
  • Use a heavy skillet like cast iron for best searing results.
  • You can substitute heavy cream with half-and-half for a lighter sauce, but it may not thicken as much.
  • Fresh thyme adds the best flavor, but dried thyme can be used in a pinch (use half the amount).
