Beef Tenderloin Steaks with Mushroom Sauce

Store-bought demiglace, a concentrated stock, is the base for this recipe’s silky mushroom sauce. A go-to in traditional French kitchens, it adds instant richness to a sauce that will taste like it’s been simmering for hours. Slideshow: More Beef Recipes

Total Time:
1 hrs


  • 6 tablespoons unsalted butter

  • 12 ounces mixed mushrooms, coarsely chopped

  • Kosher salt

  • Pepper

  • 2 cups chicken stock or low-sodium broth

  • 2 tablespoons demiglace (1.5 ounces)

  • Four 6-ounce center-cut beef tenderloin steaks

  • 2 tablespoons extra-virgin olive oil


  1. Preheat the oven to 450°. In a large cast-iron skillet, melt 2 tablespoons of the butter. Add the mushrooms and cook over moderate heat until golden brown, 10 minutes. Season with salt and pepper. Add the stock and demiglace and bring to a boil. Simmer the sauce until thickened, 10 minutes. Whisk in the remaining 4 tablespoons of butter and season with salt and pepper. Transfer the mushroom sauce to a medium bowl or saucepan and keep warm. Clean the skillet.

  2. Heat the skillet. Rub the steaks with the olive oil and season with salt and pepper. Sear over moderately high heat until browned, about 2 minutes per side. Transfer the skillet to the oven and cook the steaks until an instant-read thermometer inserted in the thickest part registers 125°, 6 to 8 minutes. Transfer the steaks to a work surface and let rest for 5 minutes. Serve the steaks with the mushroom sauce.

Make Ahead

The mushroom sauce can be refrigerated for up to 2 days and reheated gently before serving.

Serve With

Mashed potatoes and sautéed Broccolini.
