When I first tackled making filet mignon with mushroom sauce, I was nervous about cooking such a prized cut of meat. However, I learned that letting the steak come to room temperature before searing it created a beautiful crust without overcooking the inside. That’s a pivotal step I now always recommend!

The sauce, made from earthy mushrooms sautéed in garlic and finished with a splash of cream, adds a touch of luxury. I often serve it with roasted vegetables, creating a delightful balance that enhances the flavors of the steak.

Selecting the Perfect Filet Mignon

When choosing your filet mignon, look for steaks that are bright red with good marbling. Marbling refers to the small flecks of fat within the muscle, which contribute to the steak's tenderness and flavor. It's best to buy steaks that are at least 1.5 inches thick for even cooking. If you're unsure about freshness, purchasing from a trusted butcher can make all the difference. They can also trim the steaks to your desired thickness or portion size if you're cooking for fewer people.

Another consideration is whether to choose aged or fresh filet mignon. Aged steak tends to have a more complex flavor profile, which can elevate your dish even more. If you opt for aged steak, aim for one that has been dry-aged for at least 21 days. This will enhance the beef's natural flavor while still retaining that tender texture essential for a memorable filet mignon.

Mastering the Mushroom Sauce

The mushroom sauce is a vital component that ties together the richness of the filet mignon. Cremini mushrooms offer a deeper flavor than common button mushrooms, but you can also experiment with shiitake or porcini for a more robust taste. Ensure you cook the mushrooms until they're beautifully browned; this caramelization is key for developing that savory umami flavor. Avoid overcrowding the pan when you sauté the mushrooms, as this can lead to steaming rather than browning, causing a less flavorful sauce.

For a richer sauce, consider adding a splash of white wine or brandy after sautéing the mushrooms and before incorporating the cream. Letting the alcohol evaporate will imbue the sauce with complexity. If you prefer a lighter version, you can substitute half-and-half for heavy cream, but be cautious as the sauce may not thicken as well. Always taste and adjust the seasoning as you go, particularly after adding the cream, to ensure balanced flavors.

Serving Suggestions

To elevate your presentation, serve the filet mignon on a warmed plate, which helps retain the dish's temperature. Adding a side of garlic mashed potatoes or roasted asparagus complements the flavors beautifully and creates an inviting plate. For an added flourish, drizzle some balsamic reduction around the plate. It not only enhances the presentation but also introduces a tangy contrast to the richness of the steak and sauce.

If you have leftovers, slice the filet and store it in an airtight container in the refrigerator for up to three days. To reheat, do so gently in a skillet over low heat to maintain tenderness. The mushroom sauce can also be made ahead of time and stored; simply reheat it slowly before serving to avoid separating the cream. This makes the dish not only perfect for special occasions but also practical for later meals.

Ingredients

For the Steak

2 filet mignon steaks (6 oz each)
Salt and pepper to taste
2 tablespoons olive oil

For the Mushroom Sauce

8 oz cremini mushrooms, sliced
2 cloves garlic, minced
1/2 cup heavy cream
1 tablespoon Dijon mustard
1 tablespoon fresh parsley, chopped
Salt and pepper to taste

Instructions

Prepare the Steak

Remove the filet mignon steaks from the refrigerator and allow them to come to room temperature for about 15 minutes. Season both sides generously with salt and pepper.

Sear the Steaks

Heat olive oil in a skillet over medium-high heat. Once hot, add the steaks and sear for 4-5 minutes on each side for medium-rare, adjusting time to your preference.

Make the Mushroom Sauce

In the same skillet, add the sliced mushrooms and cook until browned, about 5 minutes. Stir in the minced garlic and cook for an additional minute. Then, add the heavy cream and Dijon mustard, stirring to combine. Let it simmer for 3-4 minutes until slightly thickened. Season with salt and pepper.

Serve

Plate the filet mignon and generously spoon the mushroom sauce over the top. Garnish with fresh parsley and serve immediately.

Pro Tips

Let the steak rest for a few minutes after cooking for the juiciest results. Pair this dish with a full-bodied red wine for a classic combination.

Common Mistakes to Avoid

One common mistake when searing filet mignon is not allowing the steak to reach room temperature before cooking. Taking this step ensures more even cooking and helps you achieve that beautiful crust on the outside. Additionally, if your skillet isn’t hot enough, the steak will not sear properly, leading to a gray, bland exterior instead of a beautifully caramelized crust. Always preheat your skillet to medium-high and test the heat with a drop of water; it should sizzle immediately upon contact.

Overcooking the steak is another pitfall. Use a meat thermometer to achieve precision, especially if you like your steak medium-rare; it should register between 130°F and 135°F before resting. Remember that the temperature will continue to rise slightly as it rests, so pulling it off the heat when it’s slightly below your target can help ensure perfect doneness.

Ingredient Variations

If you're looking to diversify your mushroom sauce, consider adding a splash of soy sauce or Worcestershire sauce for added depth. You can also incorporate other herbs like thyme or rosemary for a seasonal twist. Just add them in conjunction with the garlic for a fragrant aroma that will enhance the dish. If you're avoiding dairy, coconut cream can serve as a suitable alternative to heavy cream while still delivering a rich texture.

For those who prefer a different approach, consider serving the filet mignon with a red wine reduction sauce instead. This can be made by reducing a good quality red wine along with shallots and beef broth to intensify flavor. This adds a wonderful complexity, making it a great alternative to the mushroom sauce.

Making It Ahead of Time

While filet mignon is best served fresh, you can prepare the mushroom sauce ahead of time. Make it the day before and store it in the refrigerator. When you're ready to serve, simply reheat it in a saucepan over low heat, adding a splash of cream if it thickens too much. This way, you can focus on perfecting the steaks when it's time to eat.

For meal prepping, consider portioning the filet mignon into meal-sized servings. They can be vacuum-sealed and stored in the freezer for up to three months. Thaw overnight in the refrigerator before cooking to maintain quality. This makes preparing a gourmet meal much more manageable when time is tight.
