Ingredients:
For the Filet Mignon:
2 filet mignon steaks (6-8 oz each)
2 tablespoons olive oil
2 tablespoons butter
Salt and pepper, to taste
2 cloves garlic, crushed
2 sprigs fresh thyme (optional)
For the Creamy Parmesan Mustard Sauce:
1/2 cup heavy cream
1/4 cup grated Parmesan cheese
1 tablespoon Dijon mustard
1 tablespoon whole grain mustard
1/2 teaspoon garlic powder
Salt and pepper, to taste
1 tablespoon fresh parsley, chopped (optional for garnish)
Instructions:
For the Filet Mignon:
Prepare the Steaks:
Season the filet mignon generously with salt and pepper on all sides. Let the steaks sit at room temperature for 15-20 minutes before cooking.
Sear the Steaks:
Heat a large skillet or cast iron pan over medium-high heat. Add olive oil and let it heat until shimmering.
Add the filet mignon to the hot skillet and sear for 3-4 minutes on each side, until a nice crust forms. For a perfect medium-rare, aim for an internal temperature of 130°F (54°C).
Add butter, garlic, and thyme to the skillet. As the butter melts, spoon it over the steaks for about 1 minute to enhance flavor.
Rest the Steaks:
Remove the filet mignon from the skillet and let them rest on a plate covered with foil for 5 minutes.
For the Creamy Parmesan Mustard Sauce:
Make the Sauce:
In the same skillet (remove excess oil if necessary), reduce the heat to medium. Add heavy cream and bring it to a gentle simmer.
Stir in the grated Parmesan cheese, Dijon mustard, whole grain mustard, and garlic powder. Stir continuously until the sauce thickens, about 3-4 minutes.
Season the Sauce:
Add salt and pepper to taste, and adjust the mustard flavor if needed by adding more Dijon or whole grain mustard for extra tang.
To Serve:
Place the rested Filet Mignon on a plate and generously spoon the Creamy Parmesan Mustard Sauce over the top.
Garnish with chopped parsley if desired, and serve alongside your favorite sides (such as mashed potatoes or roasted vegetables).
This Filet Mignon with Creamy Parmesan Mustard Sauce offers a perfect balance of rich flavors—tender steak with a tangy, creamy sauce that elevates the dish to a whole new level of indulgence!
