Description
This Seared Filet Mignon with Blue Cheese Butter is a luxurious and flavorful steak recipe perfect for special occasions or a gourmet dinner at home.

Topped with a creamy, herbaceous blue cheese butter that melts beautifully over the warm steaks, this dish pairs wonderfully with cacio e pepe Brussels sprouts for a complete meal.
Ingredients
Steak
- 4 filet mignon steaks, about 2 inches thick
- Kosher salt, to taste
- Fresh ground black pepper, to taste
- 2 to 3 tablespoons unsalted butter
- Cacio e pepe Brussels sprouts, for serving
Blue Cheese Butter
- 6 tablespoons unsalted butter, softened
- ⅓ cup crumbled blue cheese
- 2 tablespoons chopped fresh herbs (such as parsley, thyme, basil, and chives)
Instructions
- Preheat Oven: Preheat your oven to 450 degrees Fahrenheit. For best results, use a cast iron skillet which will get a bit smoky, so ensure proper ventilation by turning on your oven vent or a fan.
- Season and Heat Skillet: Heat the cast iron skillet over medium-high heat. Generously season the filet mignon steaks on all sides with kosher salt and freshly ground black pepper. Add 2 tablespoons of butter to the hot skillet; the butter will begin to brown and smoke, which is desired for flavor.
- Sear Steaks: Immediately place the steaks in the skillet. Sear each side for about 2 minutes until a deep golden-brown crust forms. Add an additional tablespoon of butter if needed for more browning. Once both sides are seared, turn off the heat under the skillet.
- Finish Cooking in Oven: Transfer the cast iron skillet with the steaks into the preheated oven. Roast for 3 to 5 minutes to achieve medium doneness. Cooking times may vary depending on steak thickness—use a meat thermometer to check internal temperature: 120°F for rare, 125-130°F for medium rare, 135-140°F for medium, and 145-150°F for medium-well.
- Rest Steaks: Remove steaks from the oven and let them rest for 5 to 10 minutes. This allows juices to redistribute, ensuring tender and juicy meat.
- Make Blue Cheese Butter: While steaks rest, combine softened butter, crumbled blue cheese, and chopped herbs in a bowl. Mash and stir until creamy and evenly mixed. This butter can be made ahead and refrigerated for several days.
- Serve: Just before serving, place a scoop of the blue cheese butter on top of each warm steak to let it melt slightly. Serve alongside the cacio e pepe Brussels sprouts for a delicious and elegant meal.
