Ingredients You’ll Need for Filet Mignon with Creamy Mushroom Shallot Sauce

Essentials

2 filet mignon steaks (about 6–8 oz each)
2 tablespoons olive oil
Salt and freshly ground black pepper, to taste
1 cup mushrooms, sliced (cremini, baby bella, or white button)
1 shallot, finely chopped
1/2 cup heavy cream
1/2 cup beef broth (use low-sodium if you prefer)
1 tablespoon fresh thyme or parsley, chopped

Optional add-ons

1 tablespoon butter (to finish the sauce for extra richness)
1 teaspoon Dijon mustard (for a little tang in the sauce)
A splash of Worcestershire sauce (adds savory depth; optional)
Freshly grated Parmesan (sprinkled over the sauce for nuttiness)

Substitutions and Shortcuts

Mushrooms: If you don’t have shallots, use 1 small sweet onion, finely chopped. If shallots are available, they give a soft, sweet flavor that pairs beautifully with the mushrooms.
Heavy cream: For a lighter sauce, use half-and-half, but the sauce will be thinner. If you want a thicker sauce without more cream, mix 1 teaspoon cornstarch with 1 tablespoon cold water and add it at the end to thicken.
Beef broth: Use chicken or vegetable broth if you don’t have beef broth—this will lighten the flavor a bit but still be tasty.
Fresh herbs: If you don’t have thyme or parsley, dried thyme works (use 1/3 teaspoon dried). Add it earlier so it can rehydrate in the sauce.
Shortcuts: Use pre-sliced mushrooms and pre-chopped shallots if you want to save prep time. Gently pat steaks dry and season just before cooking to avoid drawing out moisture early.

How to Make Filet Mignon with Creamy Mushroom Shallot Sauce Step-by-Step

Before you start

Bring the steaks to room temperature for 20–30 minutes. This helps them cook more evenly.
Preheat your oven to 400°F (200°C) so it’s ready when you need it.
Pat the steaks dry with paper towels—dry meat sears better.

Step 1 — Season the steaks

Generously season both sides of the filet mignon with salt and freshly ground black pepper. Don’t be shy with the salt; it helps create a good crust.

Step 2 — Sear the steaks

Choose an oven-proof skillet (cast iron is ideal). Heat 2 tablespoons of olive oil over medium-high heat until the oil shimmers.
Carefully place the steaks in the hot skillet. You should hear a confident sizzle—this means you’re getting a good sear. Sear for 3–4 minutes without moving them.
Flip and sear the other side for 3–4 minutes. This creates a brown crust and locks in flavor.

Step 3 — Finish in the oven

After searing both sides, transfer the skillet to the preheated oven. Roast for 5–7 minutes for medium-rare to medium, depending on thickness and your oven. Use an instant-read thermometer if you have one: 125–130°F for medium-rare, 135°F for medium.
Remember: the steak will continue to cook a little while resting.

Step 4 — Rest the steaks

Remove the skillet from the oven and transfer the steaks to a plate. Tent loosely with foil and let them rest for about 5–10 minutes. Resting redistributes the juices and keeps the steak tender.

Step 5 — Sauté shallot and mushrooms in the same skillet

While the steaks rest, return the skillet to medium heat on the stove (be careful—the handle may be hot). If the pan is dry, add a touch more olive oil or 1 tablespoon of butter.
Add the finely chopped shallot and sauté for 1–2 minutes until fragrant. Then add the sliced mushrooms. Cook, stirring occasionally, until the mushrooms release their moisture and start to brown—about 4–6 minutes.

Step 6 — Deglaze and reduce

Pour in the beef broth and use a wooden spoon to scrape up the brown bits from the bottom of the skillet. Those browned bits add a lot of flavor to the sauce. Let the broth simmer and reduce for 2–3 minutes. If you are using Dijon or Worcestershire, stir it in now.

Step 7 — Add cream and herbs

Stir in the heavy cream and the chopped fresh thyme or parsley. Reduce the heat to low and let the sauce simmer gently, stirring, until it thickens and coats the back of a spoon—about 3–5 minutes. If you prefer a richer sauce, stir in 1 tablespoon of butter at the end. Taste and adjust seasoning with salt and pepper.

Step 8 — Plate and serve

Slice the rested steaks or serve whole. Spoon the creamy mushroom shallot sauce generously over the top. Garnish with a little extra chopped parsley or thyme for color.

Common Mistakes to Avoid

Overcrowding the Pan

Overcrowding the pan lowers the heat and traps moisture, which means your steaks won’t sear properly and your mushrooms will steam instead of caramelize. Sear the steaks with space between them. If your skillet is too small, sear one steak at a time or use a larger pan.

Skipping the Rest

Cutting into a steak right away is a common mistake. If you slice immediately after cooking, the juices will pour out and the steak will be dryer. Tent the steaks with foil and let them rest for 5–10 minutes so the juices redistribute and stay in the meat.

Rushing the Sauce

Turning the heat too high or adding the cream too early can cause the sauce to separate or scorch. Keep the heat moderate and simmer gently after adding the cream. If the sauce looks too thin, simmer a bit longer to reduce; if it gets too thick, add a splash more broth or cream to loosen it.

Serving Suggestions for Filet Mignon with Creamy Mushroom Shallot Sauce

Classic Sides: Mashed Potatoes or Creamy Polenta

A silky bed of mashed potatoes or creamy polenta is the classic, cozy partner for Filet Mignon with Creamy Mushroom Shallot Sauce. The sauce soaks into the potatoes or polenta and makes every bite comforting. For quick mash, use Yukon gold potatoes, butter, a splash of milk, and a little salt.

Roasted Vegetables or Green Beans

Lightly roasted vegetables—like carrots, asparagus, or Brussels sprouts—add color and texture. Alternatively, sautéed green beans with a squeeze of lemon and a sprinkle of toasted almonds bring brightness and a bit of crunch that pairs well with the creamy sauce.

Simple Salad or Light Grain

If you want a lighter plate, serve the steak with a simple salad of mixed greens, cherry tomatoes, and a vinegar-based dressing to cut through the richness. Farro or a small portion of wild rice also works as a wholesome base that complements the sauce without overwhelming it.

FAQs About Filet Mignon with Creamy Mushroom Shallot Sauce

Q1: How long should I cook Filet Mignon with Creamy Mushroom Shallot Sauce to get medium-rare?
A1: For medium-rare, sear the steaks 3–4 minutes per side on the stove and then roast in a 400°F (200°C) oven for about 5–7 minutes, depending on thickness. Aim for an internal temperature of about 125–130°F (52–54°C) before resting.

Q2: Can I make Filet Mignon with Creamy Mushroom Shallot Sauce ahead of time?
A2: You can cook the steaks ahead and reheat gently, but they’re best when freshly cooked. For the sauce, make it in advance and reheat slowly on low, adding a splash of broth or cream if it thickens. Reheat steaks briefly in a 300°F oven for a few minutes just before serving to warm without overcooking.

Q3: What sides pair well with Filet Mignon with Creamy Mushroom Shallot Sauce?
A3: Classic pairings include mashed potatoes, creamy polenta, roasted vegetables, sautéed green beans, or a simple green salad. Choose sides that balance the richness of the sauce and add texture.

Q4: Can I use a different cut of beef for Filet Mignon with Creamy Mushroom Shallot Sauce?
A4: Yes. If you can’t find filet mignon, try tenderloin medallions, sirloin steaks, or ribeye. Adjust cooking times for thickness and fat content—ribeye may need slightly longer because it’s thicker and fattier.

Q5: How do I thicken the sauce if it’s too thin for Filet Mignon with Creamy Mushroom Shallot Sauce?
A5: Let the sauce simmer a little longer to reduce. For a quicker fix, mix 1 teaspoon cornstarch with 1 tablespoon cold water and whisk it into the simmering sauce until it thickens. Or add a little more heavy cream and let it reduce gently.
