Ingredients
- 4 filet mignon steaks, about 6-8 oz each
- Salt and pepper, to taste
- 2 tablespoons olive oil or butter
- 1 tablespoon fresh rosemary or thyme (optional)
- 1 tablespoon butter
- 2 cloves garlic, minced
- 1 cup heavy cream
- 1/4 cup Dijon mustard
- 1/2 cup grated Parmesan cheese
- 1 tablespoon fresh parsley, chopped for garnish
Substitution Options
- Olive Oil or Butter: You can use either one, depending on your preference. Olive oil gives a slightly different flavor, while butter adds richness.
- Fresh Herbs: If you don’t have fresh rosemary or thyme, dried herbs work well too. Just use half the amount.
- Heavy Cream: For a lighter version, you can use half-and-half or even milk, but the sauce will be thinner.
- Parmesan Cheese: Grana Padano or Pecorino Romano can be used as substitutes if you don’t have Parmesan.
Preparation Section
Step 1: Prepare the Filet Mignon
Take the filet mignon out of the refrigerator about 30 minutes before cooking to allow it to come to room temperature. This step ensures even cooking. Season both sides generously with salt and pepper. The seasoning enhances the natural flavors of the beef, making it even more delicious.
Step 2: Cook the Filet Mignon
In a large skillet, heat the olive oil or butter over medium-high heat. Add the filet mignon to the skillet and sear for about 4-5 minutes on each side for medium-rare, or longer to reach your desired doneness. For added flavor, you can add fresh herbs during the last minute of cooking. The sizzling sound and the aroma of the herbs will make your kitchen feel like a high-end restaurant. Once cooked to your liking, remove the steaks from the skillet and let them rest on a plate, loosely covered with foil. This resting period allows the juices to redistribute, making the meat even more tender.
Step 3: Make the Creamy Parmesan Mustard Sauce
In the same skillet, reduce the heat to medium and melt 1 tablespoon of butter. Add the minced garlic and sauté for about 1 minute until fragrant. Pour in the heavy cream and bring it to a gentle simmer. Stir in the Dijon mustard and grated Parmesan cheese, mixing well until the sauce is smooth and creamy. Season with salt and pepper to taste. If the sauce is too thick, you can add a splash of water or additional cream to reach your desired consistency. The creamy, tangy sauce will complement the rich, savory flavors of the filet mignon perfectly.

To take this dish to the next level, try adding a touch of truffle oil to the sauce. Just a few drops will add a luxurious, earthy flavor that enhances the overall experience. It’s a small detail that makes a big difference.
Extra Info
Did you know that filet mignon comes from the smaller end of the tenderloin, which is the most tender part of the cow? This is why it’s so incredibly tender and a favorite among steak lovers. The creamy Parmesan mustard sauce is a French-inspired creation, blending the rich, nutty flavor of Parmesan with the tangy kick of Dijon mustard. It’s a match made in heaven!
Necessary Equipment
- Large skillet
- Meat thermometer (for checking doneness)
- Spatula
- Whisk
- Measuring cups and spoons
Storage
Storing this dish is simple. If you have leftovers, let them cool to roomroom temperature, then place them in an airtight container. Store in the refrigerator for up to 3 days. When reheating, it’s best to do so gently in a pan with a little bit of butter or olive oil to keep the meat moist and the sauce creamy. Avoid using the microwave, as it can dry out the meat and make the sauce separate. If you need to store the sauce separately, it can be kept in the fridge for up to 5 days. Just give it a good stir before using.
Tips and Advice
- Pro Tip: Letting the filet mignon come to room temperature before cooking helps it cook more evenly. This is key to achieving that perfect, juicy texture.
- Pro Tip: Use a meat thermometer to ensure the filet mignon is cooked to your desired doneness. Medium-rare is typically 130°F (54°C), medium is 140°F (60°C), and well-done is 160°F (71°C).
- Pro Tip: If you find the sauce is too thick, you can thin it out with a little bit of water or additional cream. This will help you achieve the perfect consistency.
Presentation Tips
- Garnish with Fresh Herbs: A sprinkle of fresh parsley or chives adds a pop of color and freshness to the dish.
- Use a Drizzle: Drizzle the creamy Parmesan mustard sauce over the filet mignon in a decorative pattern. This not only looks elegant but also ensures the sauce is evenly distributed.
- Side Dishes: Serve with a side of roasted vegetables, mashed potatoes, or a fresh salad. These sides complement the rich flavors of the filet mignon and the creamy sauce.
Healthier Alternative Recipes
- Grilled Filet Mignon with Herb Butter: Instead of the creamy sauce, top the filet mignon with a herbed butter. This keeps the dish rich and flavorful but with fewer calories.
- Filet Mignon with Red Wine Reduction: Replace the creamy sauce with a red wine reduction. This adds a deep, rich flavor without the extra cream.
- Herb-Crusted Filet Mignon: Coat the filet mignon with a mixture of fresh herbs and breadcrumbs before grilling. This adds a crispy, flavorful crust without the need for a creamy sauce.
- Filet Mignon with Balsamic Glaze: A balsamic glaze is a tangy, low-calorie alternative to the creamy sauce. It adds a sweet and sour note that complements the beef beautifully.
- Filet Mignon with Mushroom Sauce: A mushroom sauce made with reduced stock and a touch of cream is a healthier, yet still indulgent, option. The umami flavors of the mushrooms pair wonderfully with the beef.
- Filet Mignon with Roasted Garlic Aioli: A roasted garlic aioli is a lighter, more flavorful alternative to the creamy Parmesan mustard sauce. It adds a garlicky, creamy element without the heaviness.
Common Mistakes to Avoid
Mistake 1: Overcooking the Filet Mignon
Overcooking the filet mignon can turn a potentially perfect dish into a tough, chewy disappointment. To avoid this, use a meat thermometer to check the internal temperature. Aim for 130°F (54°C) for medium-rare, which is the ideal doneness for filet mignon. If you prefer a different level of doneness, adjust the temperature accordingly. Remember, the meat will continue to cook a bit after you remove it from the heat, so it’s better to err on the side of slightly underdone.
Mistake 2: Not Letting the Meat Rest
Skipping the resting step can result in a less juicy and flavorful filet mignon. After cooking, let the steaks rest on a plate, loosely covered with foil, for about 5-10 minutes. This allows the juices to redistribute, making the meat more tender and flavorful. Patience is key here; it’s worth the wait!
Mistake 3: Adding Too Much Salt
While seasoning is important, adding too much salt can overpower the delicate flavors of the filet mignon and the creamy Parmesan mustard sauce. Start with a conservative amount of salt, and taste as you go. You can always add more, but you can’t take it away once it’s there. A good rule of thumb is to season lightly and adjust as needed.
Mistake 4: Not Using Fresh Ingredients
Using stale or old ingredients, especially herbs and spices, can significantly impact the flavor of your dish. Fresh ingredients, like fresh herbs and freshly grated Parmesan cheese, make a huge difference. They bring out the best flavors and aromas, making your Parmesan mustard filet truly exceptional.
Mistake 5: Not Adjusting the Sauce Consistency
A common mistake is not adjusting the consistency of the creamy Parmesan mustard sauce. If the sauce is too thick, it can be pasty and unappealing. If it’s too thin, it won’t coat the filet mignon properly. To fix this, you can add a splash of water or additional cream to thin it out, or let it simmer a bit longer to thicken it. The goal is to get a smooth, creamy consistency that clings to the meat beautifully.
FAQ
Can I use a different cut of beef for this recipe?
While filet mignon is the traditional choice for this recipe, you can use other cuts like ribeye or sirloin. However, the texture and tenderness will vary. Filet mignon is the most tender, making it the best choice for a luxurious, melt-in-your-mouth experience.
What can I substitute for heavy cream in the sauce?

How do I know when the filet mignon is done?
