Step-by-Step Instructions
Prepare the Steaks
Remove the filet mignon from the refrigerator about 30 minutes before cooking.
Pat the steaks thoroughly dry with paper towels. Season both sides generously with sea salt and freshly ground black pepper.
Drying the surface well is important because excess moisture can interfere with developing a beautiful browned crust.
Sear the Filet Mignon
Heat a heavy-bottomed skillet over medium-high heat. A cast-iron skillet works particularly well because it retains heat efficiently.
Add the olive oil. Once the oil is hot and shimmering, carefully place the steaks in the skillet.
Sear for approximately 4 minutes without moving the steaks until a deep golden-brown crust develops.
Butter-Baste the Steaks
Flip the steaks and add the butter to the skillet.
Cook for another 3–4 minutes, spooning the melted butter repeatedly over the steaks.
For medium-rare, aim for an internal temperature of approximately 130–135°F (54–57°C) after resting. For the most accurate result, use an instant-read meat thermometer.
Transfer the steaks to a warm plate and loosely tent them with foil. Let them rest for 5–10 minutes.
Sauté the Mushrooms
Keep the same skillet over medium heat.
Add the sliced mushrooms and cook for about 5 minutes, stirring occasionally. Allow the mushrooms to release their moisture and become nicely golden.
Add the minced garlic and fresh thyme.
Cook for another minute until the garlic becomes fragrant.
Make the Creamy Mushroom Sauce
Pour the beef broth into the skillet to deglaze the pan.
Use a wooden spoon or spatula to scrape the browned bits from the bottom. These caramelized pieces add tremendous flavor to the sauce.
Pour in the heavy cream and stir well.
Reduce the heat and allow the sauce to gently simmer for 3–4 minutes, stirring occasionally, until it thickens enough to coat the back of a spoon.
Avoid boiling the cream aggressively, as excessive heat can cause the sauce to separate.
Serve
Place each rested filet mignon on a serving plate.
Spoon the warm creamy mushroom sauce over and around the steak.
Finish with fresh thyme leaves and serve immediately.
Best Tips
For the best seared crust, make sure the steaks are thoroughly dry before seasoning and cooking.
A reliable meat thermometer makes cooking filet mignon much easier because steak thickness can vary. Temperature is a better indicator of doneness than cooking time alone.
Allowing the steak to rest for several minutes after cooking gives the juices time to redistribute throughout the meat.
Do not constantly move the steaks around the skillet. Leaving them undisturbed while searing helps create a flavorful golden-brown crust.
Best Ingredient Options
Steak
Filet mignon is the classic choice, but ribeye, New York strip, or sirloin can also be used.
Mushrooms
Cremini mushrooms provide excellent flavor, while baby bella, white button, or thinly sliced portobello mushrooms are also delicious.
Broth
Low-sodium beef broth works well. Beef bone broth can provide an even richer flavor.
Herbs
Fresh thyme pairs beautifully with mushrooms and beef. Rosemary or flat-leaf parsley can also be used.
Recipe Variations
For a more savory sauce, add a teaspoon of Dijon mustard just before serving.
For a peppercorn version, add lightly crushed black peppercorns to the mushroom sauce.
For an especially luxurious variation, finish the sauce with a very small amount of truffle oil.
You can also use a dairy-free cream alternative and replace the butter with olive oil or a plant-based butter.
What to Serve With
Creamy garlic mashed potatoes are an excellent side because they absorb the mushroom sauce beautifully.
For a lighter meal, serve the filet mignon with roasted asparagus, steamed green beans, sautéed spinach, or a crisp arugula salad.
Roasted baby potatoes, cauliflower purée, or parsnip purée also make excellent accompaniments.
Make-Ahead Instructions
The mushroom sauce ingredients can be prepared in advance.
Slice the mushrooms, mince the garlic, measure the broth and cream, and store everything separately in the refrigerator for up to 24 hours.
For the best steak texture, season the filet mignon shortly before cooking.
Storage
Allow leftovers to cool promptly before transferring them to airtight containers.
Store the cooked steak and mushroom sauce separately in the refrigerator for up to 3 days.
Reheating
For the best results, slice the steak and gently warm it in a skillet over low heat.
Add the mushroom sauce with a small splash of beef broth or cream and heat gently until warmed through.
Avoid high heat because it can quickly turn the filet mignon dry and overcooked.
Freezing
The cooked steak can be wrapped tightly and frozen for up to approximately 2 months for best quality.
The creamy mushroom sauce is best enjoyed fresh because cream-based sauces can separate or develop a grainy texture after freezing and thawing.
Common Mistakes to Avoid
Overcrowding the Pan
Give the steaks plenty of space. Overcrowding lowers the pan temperature and can cause the meat to steam instead of sear.
Moving the Steak Too Much
Let the steak remain undisturbed during the initial sear so the surface has time to develop a flavorful crust.
Cutting the Steak Immediately
Rest the filet mignon for 5–10 minutes before slicing. This helps retain more of its natural juices.
Overcooking the Sauce
The mushroom sauce only needs a gentle simmer. Excessive heat can cause the cream to separate.
Skipping the Thermometer
Cooking time can vary depending on steak thickness and pan temperature. An instant-read thermometer provides a much more reliable indication of doneness.

Frequently Asked Questions
Can I use another cut of steak?
Yes. Ribeye, New York strip, sirloin, and other tender cuts can work well. Adjust the cooking time according to the thickness of the steak and desired internal temperature.
How do I clean mushrooms?
Gently wipe mushrooms with a damp paper towel or use a soft mushroom brush. If they are particularly dirty, rinse them briefly and dry them thoroughly before cooking.
Can I make this recipe dairy-free?
Yes. Replace the butter with olive oil or a plant-based butter and use a suitable dairy-free cream alternative.
Can I make the mushroom sauce without cream?
Yes. You can create a lighter mushroom pan sauce using additional beef broth and a small amount of Dijon mustard. The result will be less creamy but still flavorful.
What temperature should filet mignon reach?
For medium-rare, remove the steak from the heat when it is close to your desired final temperature, then allow it to rest. A final temperature around 130–135°F (54–57°C) is commonly used for medium-rare.
