Season the steaks with salt and pepper on both sides.
In a skillet, melt the butter over medium heat.
Add the steaks and cook to your desired doneness, then remove and set aside.
In the same skillet, add the mushrooms and garlic, sautéing until the mushrooms are tender.
Stir in the heavy cream, Dijon mustard, and Worcestershire sauce, cooking until the sauce thickens.
Return the steaks to the skillet and coat them with the sauce.
Serve hot with additional sauce drizzled over the top.
