Instructions

1. Heat 2 Tbsp butter and 1 Tbsp olive oil in a large heavy-bottomed skillet over medium-high heat. Add sliced mushrooms and cook for about 6 minutes until softened and most of their liquid has evaporated.
2. Add the diced onion and cook, stirring frequently, for 3 minutes.
3. Stir in minced garlic, thyme, ¼ tsp salt, and ⅛ tsp black pepper. Cook for 2 minutes until fragrant. Transfer the mushroom mixture to a plate and wipe the skillet clean with a damp paper towel.
4. Season the filet mignon steaks evenly with 1 tsp salt and ¼ tsp black pepper.
5. In the same skillet, heat the remaining 2 Tbsp butter and 1 Tbsp olive oil over medium-high heat. Once the butter is hot and foamy, add the steaks. Sear for 3-5 minutes per side for medium-rare, or 5-6 minutes per side for medium doneness. Transfer steaks to the plate with mushrooms when done.
6. Pour the red wine into the skillet and boil for about 3 minutes, reducing by half while scraping the browned bits off the bottom.
7. Add beef broth and continue boiling until the liquid reduces to about 2/3 cup, about 5-7 minutes.
8. Stir in the heavy cream and boil for 2 minutes until the sauce thickens slightly. Adjust seasoning with salt and pepper to taste.
9. Return the steaks and mushrooms to the skillet, spooning the sauce over the steaks. Heat through briefly.
10. Remove from heat and garnish with fresh thyme sprigs if desired. Serve immediately.
