Equipment

  • 1 large skillet (12-inch)
  • 1 Wooden spoon or spatula
  • 1 knife (for chopping mushrooms, garlic, and onion)
  • 1 cutting board
  • 1 grater (for Parmesan)
  • 1 Measuring cup (for cream)

Ingredients
  

  • 2 tablespoons olive oil
  • 2 tablespoons butter
  • 12 oz 340g fresh mushrooms (white button or cremini, sliced)
  • 1 medium onion finely chopped
  • 3 cloves garlic minced
  • 1 cup 240 ml heavy cream
  • ½ cup 50g freshly grated Parmesan cheese
  • ½ teaspoon fresh thyme optional
  • Salt and pepper to taste

Instructions
 

Sauté the Mushrooms:

  • Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the sliced mushrooms and sauté for 5-7 minutes, stirring occasionally, until they turn golden brown and release their moisture. Once cooked, remove the mushrooms from the skillet and set them aside.

Cook the Aromatics:

  • In the same skillet, add the remaining tablespoon of olive oil and butter. Once melted, add the chopped onion and cook for 2-3 minutes until softened. Add the minced garlic and sauté for another 30 seconds, ensuring it doesn't burn.

Add the Cream:

  • Pour in the heavy cream and bring the mixture to a gentle simmer. Stir frequently for about 2-3 minutes, allowing the cream to thicken slightly.

Stir in Parmesan:

  • Add the grated Parmesan cheese, stirring until it melts and the sauce becomes creamy and smooth.

Season and Combine:

  • Season with salt, pepper, and thyme. Return the sautéed mushrooms to the skillet and stir until well combined. Let everything simmer for 2-3 minutes, allowing the flavors to meld.

Serve:

  • Taste the sauce and adjust seasoning if needed. Serve over pasta, chicken, or any dish that needs a creamy mushroom upgrade.

Notes

  • Mushroom Variety: You can experiment with different types of mushrooms, such as shiitake, portobello, or a mix, for a more complex flavor.
  • Vegan Option: For a dairy-free version, substitute the heavy cream with coconut cream or plant-based cream and use vegan Parmesan cheese.
  • Thickening the Sauce: If you prefer a thicker sauce, allow it to simmer for a little longer or add a bit more Parmesan to help thicken it.
  • Make-Ahead: This sauce can be made ahead of time and stored in the refrigerator for up to 3 days. Reheat over low heat, adding a splash of cream if necessary to restore consistency.
