For the Filet Mignon
- Two filet mignon steaks, about 6 ounces each
- One tablespoon olive oil
- One tablespoon unsalted butter
- Salt and freshly ground black pepper to taste
For the Mushroom Sauce
- Eight ounces cremini or baby bella mushrooms, sliced
- Two cloves garlic, minced
- One tablespoon unsalted butter
- One tablespoon olive oil
- One tablespoon chopped shallots (optional)
- One tablespoon fresh thyme or one teaspoon dried
- Salt and pepper to taste

- Three to four tablespoons Boursin garlic and herb cheese (room temperature)
Preparation Time
- Prep time: 10 minutes
- Cooking time: 20 minutes
- Resting time: 5 minutes
- Total time: 35 minutes
Step-by-Step Instructions
Step 1: Prepare the Filet Mignon
- Remove the steaks from the refrigerator 20 to 30 minutes before cooking to bring them to room temperature.
- Pat dry with paper towels and season both sides generously with salt and pepper.
- Heat one tablespoon olive oil and one tablespoon butter in a heavy skillet (preferably cast iron) over medium-high heat.
- When the pan is hot and the butter is foaming, sear the steaks for about three to four minutes per side for medium-rare, adjusting based on thickness.
- For extra precision, use a meat thermometer: 130°F for medium-rare, 140°F for medium.
- Remove from heat, place steaks on a plate, and let rest for five minutes before serving.
Step 2: Sauté the Mushrooms
- In the same skillet, reduce heat to medium and add the remaining tablespoon of oil and butter.
- Add the shallots and garlic; sauté for one to two minutes until fragrant.
- Add sliced mushrooms and thyme, stirring to coat.
- Cook for five to seven minutes until mushrooms are browned and their moisture has evaporated.
- Season with salt and pepper to taste, then set aside.
Step 3: Assemble and Serve
- Once the steaks have rested, place them on serving plates.
- Top each steak with one to two tablespoons of Boursin cheese. The heat from the meat will begin to soften and melt it slightly.
- Spoon the sautéed mushrooms generously over the top or alongside.
- Serve immediately, optionally garnished with a sprig of thyme or a drizzle of pan juices.
Serving Suggestions
- Pair with roasted garlic mashed potatoes or creamy polenta for a comforting side.
- Add a green vegetable like asparagus, broccolini, or haricots verts for color and balance.
- Serve with a glass of bold red wine such as Cabernet Sauvignon or Syrah for a full-bodied pairing.
