Ingredients

For the Steaks:

• 4 filet mignon steaks (6–8 oz each; ~1½” thick)
• Salt and freshly ground black pepper
• 2 Tbsp unsalted butter
• 1 Tbsp olive oil

For the Mushroom Sauce:

• 16 oz baby bella mushrooms, thickly sliced
• 1 small onion or shallot, finely diced
• 3–4 garlic cloves, minced
• 1 Tbsp fresh thyme (or 1 tsp dried)
• ½ cup dry red wine (e.g., Merlot) or beef broth substitute
• 1½ cups beef broth
• ½ cup heavy cream
• Additional butter (optional, for finishing)

Instructions

1. Sear the Steaks: Pat steaks dry, season with salt and pepper. Heat butter and oil in a heavy skillet; sear steaks 3–5 minutes per side for medium-rare. Transfer to a plate and rest.
2. Cook Mushrooms & Aromatics: In the same skillet, sauté mushrooms, onions, and garlic in butter/oil until mushrooms soften. Add thyme.
3. Deglaze & Build Sauce: Pour in wine, stirring to deglaze and let reduce by half. Add beef broth and boil until reduced to about ⅔ cup.
4. Finish Sauce: Stir in heavy cream and simmer until slightly thickened. Return steaks to heat through. Season to taste.

Tips

• Dry steaks properly before searing to ensure a golden crust.
• Let steaks rest after searing; this helps retain juices.
• Use a heavy skillet (such as cast-iron) to get a beautiful sear and deep flavor.
• Don’t scrub the fond (brown bits)—use it to flavor the sauce when deglazing with wine or broth.

Variations & Substitutions

• Wine-free option: Omit red wine and use extra broth; sauce remains flavorful.
• Mushroom swaps: Try cremini, shiitake, or a mix for extra umami.
• Cream alternative: Use half-and-half or sour cream for a lighter sauce.
• Herb twist: Swap thyme for rosemary or add a dash of truffle oil for indulgence.

Serving Suggestions

• Serve over creamy mashed potatoes or buttery egg noodles to soak up the sauce.
• Add a side of roasted asparagus or steamed broccoli for color and balance.
• Pair with a glass of Merlot or your favorite red wine.
