Fancy Night In: Filet Mignon With a Mushroom Wine Sauce
Ingredients
6 Tbsp butter, divided
4 Tbsp olive oil, divided
16 oz baby bella mushrooms, thickly sliced
1 small or 1/2 medium red onion, finely diced
4 medium garlic cloves, minced
2 Tbsp chopped fresh thyme ( reserve a few sprigs for garnish)
4 Wellborn 2R Filet Mignon (Tenderloin Steaks) steaks (about 8 ounces each)
1/2 cup a good Cabernet or Merlot you would drink
1 1/2 cups low sodium beef broth
1/2 cup heavy whipping cream
Salt and Pepper to taste
Method
Place a large cast iron pan over medium/high heat and melt 3 Tbsp butter and 2 Tbsp oil. Add mushrooms and cook 3-5 minutes until soft. Stir in onion and cook another 3 minutes. Press in garlic cloves then season with salt, pepper, and freshly chopped thyme. Cook another 2 min, stirring constantly until garlic is fragrant, then transfer mushroom mixture to a plate. Wipe the skillet clean with a wet paper towel.
Pat dry steaks with a paper towel and season all over with sea salt and cracked pepper.
Place the same pan over medium/high heat and add 3 Tbsp butter and 2 Tbsp oil. When butter is hot and finished foaming, add seasoned steaks to skillet, turning over once with tongs, about 3-5 min per side for medium-rare. To best determine doneness, use an instant-read thermometer and utilize these helpful tips. If steak is browning too fast, reduce heat to medium. Use tongs to transfer steaks to the plate with mushrooms. Also, keep in mind thinner steaks will cook faster and thicker steaks can take longer.
Add 1/2 cup wine and boil until reduced by half (3 minutes), scraping the bottom with a wooden spoon to deglaze the pan. Add 1 1/2 cups broth and boil until about 2/3 cup liquid remains (5-6 minutes). Add 1/2 cup of cream and boil until sauce thickens slightly (2 minutes). Return mushrooms and steak to the pan and heat until warmed through (1-2 minutes)
Season sauce to taste with more salt & pepper, if desired. Serve immediately. Plate the steak and sauce over some creamy mashed potatoes and a side of steamed asparagus.
