A delightful dish combining tender beef with a rich mushroom sauce, perfect for a special dinner.
Heat half of the butter in a large skillet over medium heat.
Ensure the butter is melted but not browned for a smooth sauce base.
Add the mushrooms to the skillet and sauté until tender, about 6 minutes.
Stir occasionally to cook the mushrooms evenly.
Sprinkle the flour, pepper, garlic powder, and salt over the mushrooms and stir until combined.
Mix well to avoid lumps in the sauce.
Gradually pour in the cream while whisking, and bring the mixture to a gentle boil.
Whisk continuously to ensure a smooth and creamy sauce.
Cook and stir the sauce until thickened, about 2 minutes, then stir in the parsley and set aside.
Adding parsley at the end preserves its fresh flavor.
In another skillet, heat the remaining butter over medium heat.
Use a clean skillet to avoid mixing flavors.
Cook the beef tenderloin steaks for 6 minutes, flipping halfway, or until they reach your desired doneness.
Use a meat thermometer to ensure the steaks are cooked to your preference.
Serve the steaks topped with the mushroom sauce.
Garnish with additional parsley for a touch of color and freshness.
