Ingredients

Scale
  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 1 pound cremini or button mushrooms, sliced
  • 2 cloves garlic, minced
  • 1/2 teaspoon dried thyme
  • 1/4 cup dry white wine (optional, for deglazing)
  • 1 cup beef or vegetable broth
  • 1/2 cup heavy cream
  • 1 teaspoon Dijon mustard
  • 1/2 teaspoon salt, or to taste
  • 1/4 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. Stir and continue cooking until the mushrooms release their liquid and turn a deep golden brown, about 8 to 10 minutes total.
  3. Add the minced garlic and dried thyme to the skillet. Cook for 1 minute until fragrant.
  4. If using wine, pour it into the skillet and scrape up any browned bits from the bottom. Let the wine reduce by half, about 2 minutes.
  5. Pour in the broth and Dijon mustard. Bring the mixture to a simmer and cook until the liquid has reduced by about one-third, concentrating the flavor, about 5 minutes.
  6. Reduce the heat to low. Stir in the heavy cream and let the sauce gently warm through for 2 minutes. Do not boil after adding the cream.
  7. Season with salt and pepper to your taste.
  8. Remove from heat. Stir in the fresh parsley just before serving over steak, chicken, or pasta.

Notes

  • For a thicker, gluten-free mushroom gravy, whisk 1 tablespoon of cornstarch with 2 tablespoons of cold water to create a slurry. Whisk this slurry into the simmering broth (Step 4) before adding the cream.
  • If you skip the wine, add 1/4 cup of the broth first to deglaze the pan.
  • This sauce pairs well with mashed potatoes as a savory topping.
