Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

For the Mushroom Sauce:

• 4 tbsp unsalted butter, divided
• 2 tbsp olive oil, divided
• 16 oz baby bella mushrooms, thickly sliced
• 1 small onion, finely diced
• 4 garlic cloves, minced
• 1 tbsp fresh thyme, minced (or 1 tsp dry thyme)
• 1 ½ cups beef broth
• ½ cup whipping cream
• 1 ¼ tsp sea salt, divided
• ½ tsp black pepper, divided

For the Filet Mignon:

• 24 oz filet mignon (beef tenderloin) steaks, 6-8 oz each, about 1 ½” thick

Directions

How to Cook Filet Mignon:

1. Prepare the Mushroom Sauce:
   • Place a large, heavy-bottomed pan over medium-high heat. Melt 2 tbsp butter and 1 tbsp oil. Add the sliced mushrooms and cook for about 6 minutes, or until softened and most of the liquid has evaporated.
   • Add the diced onion and cook for another 3 minutes, stirring often.
   • Stir in the minced garlic, 1 tbsp fresh thyme, ¼ tsp salt, and ⅛ tsp black pepper. Cook, stirring constantly, for about 2 minutes until the garlic becomes fragrant.
   • Transfer the cooked mushrooms to a plate and set aside. Wipe the pan clean with a wet paper towel.
2. Cook the Filet Mignon:
   • Season both sides of the filet mignon steaks with 1 tsp salt and ¼ tsp black pepper.
   • In the same pan, add 2 tbsp butter and 1 tbsp olive oil. When the butter is hot and foaming, add the seasoned steaks and sear for 3-5 minutes per side for medium-rare (5-6 minutes for medium). Turn the steaks once to ensure even cooking.
   • Once the steaks are cooked to your liking, transfer them to the plate with the mushrooms.
3. Make the Sauce:
   •  for 3 minutes or until it’s reduced by half, scraping the bottom of the pan to deglaze.
   • Add the beef broth and boil for another 5-7 minutes until only about ⅔ cup of liquid remains.
   • Stir in the whipping cream and cook for 2 minutes, or until the sauce slightly thickens. Taste and adjust seasoning with salt and pepper as needed.
4. Finish the Dish:
   • Return the steaks and mushrooms to the pan, spooning some of the sauce over the steaks. Let them heat through for 1-2 minutes, then remove from heat.
   • Garnish with fresh sprigs of thyme if desired and serve immediately.

FAQs

Can I use other cuts of beef for this recipe?

While filet mignon is the best for its tenderness, you can substitute it with other tender cuts like ribeye or strip steak. Just adjust the cooking times based on the thickness of the steak.

Can I use frozen steaks?

Yes, frozen steaks can be used, but make sure to thaw them completely before cooking to ensure even cooking.

What side dishes go well with this?

This dish pairs well with roasted vegetables, mashed potatoes, or a fresh green salad.

How do I know when my filet mignon is done?

Use a meat thermometer to check for the desired doneness. For medium-rare, the internal temperature should reach 130°F (54°C), and for medium, it should be 140°F (60°C).
