BEST STEAK SAUCE FOR FILET MIGNON RECIPES

Steps:

• Step 1: Place a large heavy-bottomed pan over medium/high heat and melt in 2 Tbsp butter and 1 Tbsp oil. Add thickly sliced mushrooms and cook 5 min until soft. Stir in onion and cook another 3 minutes. Press in garlic cloves then season with 1/4 tsp salt, 1/4 tsp pepper and 1 Tbsp fresh thyme. Cook another 2 min, stirring constantly until garlic is fragrant, then transfer the mushroom mixture to a plate. Wipe the skillet clean with a wet paper towel.
• Step 2: Pat dry steaks with a paper towel and season all over with salt and pepper (we use a total of 1 tsp salt and 1/4 tsp pepper).
• Step 3: Place the same pan over medium/high heat and add 2 Tbsp butter and 1 Tbsp oil. When butter is hot and finished foaming, add seasoned steaks to skillet and saute, turning over once with tongs about 3-5 min per side for medium-rare (I cooked 5-6 min per side for medium doneness). If steak is browning too fast, reduce heat to medium. Use tongs to transfer steaks to the plate with mushrooms. Please note that thinner steaks will cook faster and thicker steaks can take longer.
• Step 4: Add 1/2 cup Merlot (any will do) and boil until reduced by half (3 min), scraping the bottom with a spatula to deglaze the pan. Add 1 1/2 cups broth and boil until about 2/3 cup liquid remains (5-6 min). Add 1/2 cup cream and boil until sauce thickens slightly (2 min). Return mushrooms and steak to the pan and heat until warmed through (1 - 2 min). Season sauce to taste with more salt & pepper if desired (I added about 1/4 tsp more salt).
• Step 5: Plate the steak and spoon generous amounts of mushroom sauce over the top.
