How to Make Steak with Mushroom Sauce and Creamy Mashed Potatoes
Ingredients
- 2 ribeye or filet mignon steaks about 1 inch thick

In the same skillet, add 2 tablespoons of butter and sauté the sliced mushrooms until they are browned, about 5-7 minutes. Add the minced garlic and cook for another minute.

Pour in the beef broth and let it simmer for a few minutes until it reduces. Stir in the heavy cream and season with salt and pepper. Let the sauce simmer until it thickens slightly.
