Ingredients for Filet Mignon and Mushroom Sauce Recipe
For the Filet Mignon
- 2–4 filet mignon steaks (1½–2 inches thick)
- 2 tablespoons olive oil
- 1 tablespoon unsalted butter
- Salt and freshly ground black pepper (generously applied)
- 2–3 garlic cloves, slightly smashed
- 2 sprigs fresh rosemary or thyme
For the Mushroom Sauce
- 2 tablespoons butter
- 1 tablespoon olive oil
- 8 oz cremini or button mushrooms, sliced
- 2 garlic cloves, minced
- 1 medium shallot, finely chopped
- ½ cup beef broth
- ½ cup heavy cream
- ¼ cup white wine (optional but recommended)
- 1 teaspoon Dijon mustard
- Salt and pepper to taste
- Fresh parsley (for garnish)
How to Prepare Filet Mignon and Mushroom Sauce Recipe
Step 1: Bring the Steaks to Room Temperature
Remove the steaks from the refrigerator 25–30 minutes before cooking. This helps them cook evenly and prevents a cold center.
Step 2: Season Generously
Pat the steaks dry with paper towels.
Season all sides generously with salt and black pepper. Don’t be shy—this cut of steak benefits from a bold seasoning.
Step 3: Sear the Filet Mignon
- Heat a heavy skillet (cast iron is best) over medium-high heat.
- Add olive oil and wait until it shimmers.
- Carefully place the steaks into the skillet.
- Sear for 2–3 minutes per side without moving them.
- Add butter, garlic, and rosemary or thyme.
- Tilt the pan and spoon the melted garlic-herb butter over the steaks for added flavor.
Step 4: Finish in the Oven (Optional but Highly Recommended)
For thick steaks:
- Transfer the skillet to a preheated 400°F (204°C) oven.
- Cook for:
- Rare: 4–5 minutes
- Medium-rare: 6–7 minutes
- Medium: 7–8 minutes
Use a thermometer for accuracy:
- Rare: 125°F
- Medium-rare: 135°F
- Medium: 145°F
Step 5: Rest the Steaks
Remove the filet mignon from the pan and let it rest on a plate for 5–10 minutes.
This allows the juices to settle and ensures a tender, flavorful bite.
How to Make the Mushroom Sauce
Step 1: Sauté the Mushrooms
In the same skillet used for the steaks (leave the browned bits!), add butter and olive oil.
Sauté mushrooms for 5–6 minutes until softened and lightly browned.
Step 2: Add Aromatics
Stir in the minced garlic and chopped shallot. Cook for 1–2 minutes until aromatic.
Step 3: Add Wine & Broth
Pour in the white wine to deglaze the pan.
Scrape up the flavorful brown bits with a wooden spoon.
Let the wine reduce by half.
Add the beef broth and simmer for 3–4 minutes.
Step 4: Add Cream & Mustard
Reduce the heat to medium-low.
Stir in the heavy cream and Dijon mustard.
Simmer until the sauce thickens to your liking.
Step 5: Season & Finish
Taste and adjust with salt and pepper.
Garnish with chopped parsley.
Pour the warm sauce over your rested steaks.

Tips for Perfect Filet Mignon and Mushroom Sauce Recipe Every Time
1. Use a Cast-Iron Skillet
It holds heat exceptionally well and gives a beautiful sear.
2. Don’t Skip Resting
Cutting into your steak too soon releases all the juices.
Resting = juicier, more tender steak.
3. Avoid Overcooking
Filet mignon is best when tender and pink in the center.
Use a meat thermometer for accuracy.
4. Dry the Steaks Before Seasoning
This ensures a proper sear and prevents steaming.
5. Don’t Overcrowd the Pan
Cook in batches if needed.
Overcrowding leads to uneven browning.
6. Taste Your Sauce
Always adjust the seasoning after adding cream.
7. Add Butter Toward the End
Butter burns quickly; finish with it for a rich flavor without the bitterness.
Variations to Try
This Filet Mignon and Mushroom Sauce Recipe is incredibly adaptable. Try any of the variations below to switch things up.
1. Peppercorn Filet Mignon
Add crushed black peppercorns to the steak before searing.
Perfect for spice lovers.
2. Blue Cheese Filet
Top with a small pat of blue cheese before serving for bold, tangy flair.
3. Balsamic Mushroom Sauce
Swap wine for balsamic vinegar for a deeper, sweeter flavor.
4. Bacon-Wrapped Filet Mignon
Wrap each steak with a strip of bacon before cooking.
Adds smokiness and keeps the steak moist.
5. Creamy Parmesan Mushroom Sauce
Add a handful of grated Parmesan to make the sauce extra decadent.
6. Truffle Filet Mignon
A drizzle of truffle oil on the finished steak elevates it instantly.
7. Keto-Friendly
Skip the wine and serve with a low-carb veggie like cauliflower mash.
FAQs
1. What is filet mignon exactly?
Filet mignon comes from the tenderloin, the most tender cut of beef.
It’s lean, buttery, and cooks beautifully in minutes.
2. Can I grill filet mignon instead of pan-searing?
Absolutely! Sear on high heat for grill marks, then cook on indirect heat until desired doneness.
3. Can I make the mushroom sauce ahead of time?
Yes. Prepare it 1–2 days ahead and reheat gently before serving.
4. Do I need to use wine in the sauce?
No, but wine adds depth.
You can substitute extra broth or a splash of balsamic vinegar.
5. Should filet mignon be cooked rare?
Many consider medium-rare the ideal doneness, but it depends on preference.
6. Can I use another type of mushroom?
Definitely. Shiitake, oyster, or portobello mushrooms all work beautifully.
7. What if I don’t have rosemary or thyme?
Use any fresh herb you enjoy—sage, oregano, or parsley are all good substitutes.
8. Can I use a stainless-steel skillet instead of cast iron?
Yes, but cast iron provides the best sear and even heat distribution.
9. How do I keep the steaks from sticking to the pan?
Wait until the oil is hot before adding the steaks.
Don’t move them until the crust forms.
10. What sides go best with this Filet Mignon and Mushroom Sauce Recipe?
Mashed potatoes, roasted vegetables, pasta, or sautéed greens are all classics.
