Ingredients

Scale
  • 1 tablespoon unsalted butter
  • 1 tablespoon olive oil
  • 1 pound cremini or white button mushrooms, sliced
  • 2 cloves garlic, minced
  • 1/2 teaspoon dried thyme
  • 1/4 cup dry white wine (optional, for deglazing)
  • 1 cup heavy cream
  • 1/2 cup low-sodium chicken or vegetable broth
  • 1 teaspoon Dijon mustard
  • 1/4 teaspoon salt, or to taste
  • 1/8 teaspoon black pepper, or to taste
  • 1 tablespoon fresh parsley, chopped (for garnish)

Instructions

  1. Heat the butter and olive oil in a large skillet over medium-high heat.
  2. Add the sliced mushrooms to the hot skillet. Cook without stirring for 3 to 4 minutes to allow them to brown.
  3. Stir the mushrooms and continue cooking until they release their moisture and the liquid evaporates, about 5 to 7 minutes total. You want the mushrooms to be nicely browned.
  4. Add the minced garlic and dried thyme to the skillet. Cook for 1 minute until fragrant.
  5. If using, pour in the white wine and scrape up any browned bits from the bottom of the pan. Let the wine reduce by half, about 1 minute.
  6. Stir in the chicken or vegetable broth and Dijon mustard. Bring the mixture to a simmer.
  7. Reduce the heat to medium-low. Pour in the heavy cream and stir well. Let the sauce simmer gently for 3 to 5 minutes, stirring occasionally, until it thickens enough to coat the back of a spoon. Do not boil rapidly.
  8. Season the sauce with salt and pepper. Taste and adjust seasoning as needed.
  9. Remove from heat. Stir in half of the fresh parsley.
  10. Serve immediately over your chosen dish. Garnish with the remaining parsley.

Notes

  • For an even richer flavor, substitute half of the heavy cream with full-fat sour cream or crème fraîche, added at the very end off the heat.
  • If you skip the wine, use 1/4 cup extra broth and add a small squeeze of lemon juice for brightness.
  • This sauce pairs well with grilled steak or chicken, or tossed with fettuccine for a quick pasta dish. If you are looking for alternatives to traditional steak toppings, this sauce is a great option, similar to what you might find with some meal planning services.
