Detailed Recipe Steps
1. Prepare the Marinade for the Filet Mignon
Start by mixing the marinade in a small bowl. Combine the olive oil, lemon juice, fresh thyme leaves, salt, and pepper. This marinade not only enhances the flavor of the steak but also tenderizes the meat. Place the filet mignon in a resealable bag or shallow dish and pour the marinade over the steaks, ensuring they are well-coated. Seal or cover the container and refrigerate for at least 30 minutes, but ideally for up to 2 hours to maximize flavor.
2. Preheat the Grill
While the steak is marinating, preheat your grill to medium-high heat. A properly heated grill is crucial for achieving those beautiful grill marks and sealing in the juices of the steak. If you’re using a charcoal grill, allow the coals to burn until they are covered with white ash.
3. Prepare the Fries
Next, it’s time to make the Parmesan-crusted fries. Preheat your oven to 425°F (220°C). In a large mixing bowl, combine the cut fries with olive oil, garlic powder, salt, and pepper. Toss them well to ensure even coating. Spread the fries in a single layer on a baking sheet lined with parchment paper to prevent sticking. Bake for about 25-30 minutes or until they are golden and crispy. For the last 5 minutes of baking, sprinkle the grated Parmesan cheese over the fries to allow it to melt and crisp up.
4. Cook the Filet Mignon
Once the grill is hot and the fries are in the oven, remove the filet mignon from the marinade. Let any excess marinade drip off before placing the steaks on the grill. Cook for about 4-5 minutes on each side for medium-rare, or adjust the cooking time according to your desired level of doneness. Use a meat thermometer for accuracy 130°F (54°C) for medium-rare. After grilling, remove the steaks from the grill and let them rest for about 5 minutes to allow the juices to redistribute.
5. Make the Wild Mushroom Cream Sauce
While the steak rests, prepare the wild mushroom cream sauce. In a skillet over medium heat, melt the butter. Add the sliced wild mushrooms and sauté them until golden brown, about 5-7 minutes. Stir in the minced garlic and cook for another minute until fragrant. Then, pour in the heavy cream and add fresh thyme, salt, and pepper. Let the sauce simmer for 5-10 minutes until it thickens slightly. This step is crucial as it enhances the depth of flavor in the sauce.
6. Serve
To serve, place the grilled filet mignon on plates and generously top with the wild mushroom cream sauce. Arrange the Parmesan-crusted fries on the side, and garnish with additional thyme if desired. Enjoy your gourmet meal that is sure to impress everyone at the table!
