  • 16 ounces cremini mushrooms (baby Bella), cleaned gently with a damp paper towel and your preference of slice sizes
  • 4 tablespoons butter
  • 1 tablespoon olive oil
  • 3 to 4 cloves garlic, minced
  • 1 teaspoon dried thyme
  • ¼ teaspoon salt
  • ¼ teaspoon pepper
  • ½ cup milk
  • 1 tablespoon cornstarch
  • 1 cup heavy whipping cream
  • 1 cup fresh grated parmesan cheese, divided into ¾ cup and ¼ cup
  • 2 tablespoons fresh parsley, roughly chopped
  • teaspoon red pepper flakes, optional
  • fresh thyme, several sprigs (optional)
  • fresh parsley chopped, for garnish


  • In a large cast-iron skillet over medium heat, melt the butter and olive oil.
  • Add the sliced mushrooms and minced garlic and cook until tender and brown, about 15 minutes.
  • Sprinkle the dried thyme over the mushrooms and cook for about one minute stirring several times.
  • Season with salt and pepper.
  • Mix the cornstarch into the ½ cup of milk and pour into skillet with the mushrooms. Stir until thickened.
  • Add the heavy whipping cream, ¾ cup of grated parmesan cheese, chopped parsley, red pepper flakes and fresh sprigs of thyme.
  • Lower the heat to medium-low and stir until the cheese melts. Remove the woody sprigs of thyme.

  • High-quality ingredients make all the difference in this fresh dish, try to use the best quality you can find, especially the parmesan cheese.
  • Stir frequently to make sure the garlic doesn't burn in the pan.
  • The cornstarch slurry will thicken the creamy sauce even more.
