Smothered steaks with creamy mushroom sauce are the kind of dish that feels instantly special. Rich, comforting, and deeply satisfying, this is classic steakhouse food — but made simply, at home, in one skillet. Tender steaks are seared until perfectly cooked, then finished in a velvety mushroom sauce with just enough richness to feel indulgent without being heavy.

It’s the kind of recipe that works just as well for a cozy night in as it does for a celebratory dinner, when you want something impressive that doesn’t require hovering over the stove all evening.

Ingredients

  • 4 beef tenderloin filets (about 6 ounces each, 1-inch thick)
  • ½ teaspoon freshly ground black pepper
  • 2½ teaspoons kosher salt, divided
  • 1 tablespoon neutral oil (such as canola)
  • 1 cup beef stock
  • 2 tablespoons unsalted butter
  • 8 ounces mixed wild mushrooms, finely chopped
  • 1 medium shallot, finely minced
  • 3 garlic cloves, minced
  • ½ cup heavy cream
  • 2 teaspoons Dijon mustard
  • 2 teaspoons Worcestershire sauce
  • 1 tablespoon fresh tarragon, chopped
  • Flaky sea salt, for finishing

Directions:

Cook the steaks
Season the steaks on both sides with the pepper and 2 teaspoons of the salt. Heat a large cast-iron skillet over high heat until very hot, then add the oil. When the oil begins to shimmer, add the steaks and cook, turning every couple of minutes, until nicely seared and a thermometer reads about 125°F for medium-rare, roughly 8–10 minutes total.

Transfer the steaks to a plate and loosely tent with foil. Carefully wipe out the skillet.


Reduce the stock
Lower the heat slightly and pour the beef stock into the skillet. Bring to a simmer, scraping up any browned bits, and let it reduce until only a few tablespoons remain, about 3–5 minutes. Pour the reduced stock into a small bowl and set aside.


Build the mushroom sauce
Return the skillet to high heat and melt the butter. Add the mushrooms and cook, stirring occasionally, until deeply browned and their moisture has cooked off, about 5 minutes.

Reduce the heat to medium-high and stir in the shallot and garlic. Cook until softened and fragrant, 1–2 minutes.

Pour the reduced stock back into the skillet, then add the cream, Dijon mustard, Worcestershire sauce, and remaining ½ teaspoon salt. Stir to combine.


Finish the dish
Nestle the steaks back into the skillet and spoon the sauce over the top. Cook for another 1–2 minutes, turning once, until the sauce thickens slightly and the steaks are warmed through.

Remove from heat, spoon plenty of sauce over each steak, and finish with fresh tarragon and a sprinkle of flaky sea salt.
