Making the Mushroom Truffle Filet Mignon is an experience I cherish deeply. The key to this sophisticated dish lies in the quality of your ingredients—fresh mushrooms and a high-quality cut of beef truly make the difference. I recommend sourcing a nice cut of filet mignon, as its tenderness complements the deep flavors of the truffle oil beautifully.

Additionally, I found that letting the filet rest after cooking allows the juices to redistribute, enhancing the overall richness of each bite. Pair this dish with a simple green salad or roasted vegetables for a complete meal that feels decadent yet is surprisingly manageable to create.

The Importance of Temperature

When cooking filet mignon, achieving the right internal temperature is key to enjoying its tender, juicy texture. For medium-rare, aim for an internal temperature of about 130°F (54°C), which should take approximately 3-4 minutes per side over high heat. Use a meat thermometer to take the guesswork out and ensure consistent results. If you prefer your steak cooked more, allow for an additional minute per side while keeping a close eye on the temperature to avoid overcooking.

Allowing the steak to rest after cooking is crucial. This step redistributes the juices, preventing them from running out when you cut into the meat. Take the time to rest your filet mignon for 5-10 minutes before serving. This ensures that each bite remains moist and flavorful, contributing to an elevated dining experience.

Choosing Your Mushrooms

The type of mushrooms used can significantly influence the dish's flavor profile. Cremini mushrooms are a great choice for their rich flavor, but shiitake mushrooms offer a more robust umami kick. If you're looking for something more luxurious, try incorporating some porcini or wild mushrooms. You can even mix different varieties to create a more complex flavor, just be sure to adjust the cooking time if using thicker varieties, as they will take longer to brown and release moisture.

Finely chopping the mushrooms is essential for the sauté method used in this recipe. The smaller pieces caramelize better, enhancing the earthy tones that complement the filet mignon. Aim for a uniform chop to ensure even cooking. If you find that your mushrooms are releasing too much moisture during cooking, consider sautéing them in batches, allowing for better browning and flavor development.

Serving Suggestions

To keep the gourmet feel of your Mushroom Truffle Filet Mignon, consider serving it alongside creamy mashed potatoes or a simple arugula salad tossed with a light vinaigrette. The freshness of the salad cuts through the richness of the steak, balancing flavors beautifully. Another delightful side could be roasted vegetables, which add color and additional layers of taste to your meal.

For a more luxurious touch, you could drizzle a bit more truffle oil on the finished dish or serve with a side of truffle butter, which melts beautifully over the warm steak. This elevates the dish even further and makes for a stunning presentation that will impress any guest. Remember to slice the steak against the grain for tender bites that enhance the overall dining experience.

Ingredients

For the Mushroom Truffle Filet Mignon

2 filet mignon steaks (6 oz each)
1 cup mushrooms, finely chopped (preferably cremini or shiitake)
2 tablespoons truffle oil
1 tablespoon olive oil
2 cloves garlic, minced
1 tablespoon fresh thyme leaves
Salt and pepper to taste

Steps

Prepare the Filet Mignon

Season the filet mignon steaks generously with salt and pepper. Let them sit at room temperature for about 15 minutes while you prepare the mushroom mixture.

Sauté the Mushrooms

In a skillet, heat the olive oil over medium-high heat. Add the garlic and mushrooms, sautéing until they are browned and the moisture has evaporated, about 5-7 minutes. Stir in the thyme and remove from heat. Drizzle with truffle oil and mix well.

Cook the Filet Mignon

In the same skillet, add a bit more olive oil if needed and increase the heat to high. Sear the filet mignon steaks for 3-4 minutes on each side, or until they reach your desired doneness. Use a meat thermometer for precision.

Rest and Serve

Remove the steaks from the skillet and let them rest for 5-10 minutes. Top each steak with the sautéed mushrooms before serving. Enjoy your gourmet dish!

Pro Tips

For an extra touch of indulgence, consider serving the filet mignon with a side of truffle mashed potatoes or a glass of red wine. Adjust the amount of truffle oil to your liking, as it can be quite strong.

Ingredient Substitutions

If you're looking to lighten the dish, consider using less truffle oil or even swapping it for a truffle salt to achieve similar flavors without the intense richness. Additionally, you can use a leaner cut of beef, such as sirloin, though it may not offer the same tenderness as filet mignon. If you'd like a vegetarian option, substitute the steak for a hearty portobello mushroom cap, marinated and grilled to mimic the rich flavors and textures of the filet.

In case you're out of thyme, fresh rosemary or oregano can also work; however, use them sparingly, as they tend to have a stronger flavor. Dried herbs can also substitute fresh but remember to adjust the quantity, as dried herbs are more concentrated in taste.

Make-Ahead Tips

The mushroom mixture can be prepared ahead of time and stored in the refrigerator for up to two days. Simply reheat it gently in a skillet before serving to ensure it's warm. This makes it convenient for hosting, as you can focus on cooking the filet mignon just before your guests arrive. Be sure to let the mushroom mixture come to room temperature before adding it on top of the steaks to avoid losing heat.

If you're planning to serve this dish at a gathering, consider cooking the steaks slightly less than desired, removing them from heat while they are still a few degrees below your target temperature. Then, place them in a warm oven (around 200°F or 93°C) until you're ready to serve. This method helps keep the steaks beautifully warm without overcooking them, ensuring a tender, succulent bite.
