Ingredients

Ingredient Quantity Notes
Cremini or Button Mushrooms 500 grams (about 4 cups sliced) Fresh, cleaned and sliced
Olive Oil 2 tablespoons For sautéing
Butter or Vegan Butter 2 tablespoons Optional for richness
Yellow Onion 1 medium, finely chopped Provides sweetness and depth
Garlic Cloves 3 cloves, minced For aromatic flavor
All-Purpose Flour 2 tablespoons To thicken the sauce
Vegetable Broth 1 ½ cups Low sodium preferred
Heavy Cream or Plant-Based Cream ½ cup Use coconut or cashew cream for vegan option
Fresh Thyme 1 teaspoon Or ½ teaspoon dried thyme
Salt and Black Pepper To taste Enhances flavors
Fresh Parsley 2 tablespoons, chopped For garnish and freshness

Equipment

  • Large skillet or sauté pan
  • Sharp knife and cutting board
  • Measuring cups and spoons
  • Wooden spoon or silicone spatula
  • Small whisk
  • Serving spoon

Instructions

  1. Prepare the Mushrooms: Start by cleaning your mushrooms with a damp cloth or paper towel to remove any dirt. Avoid rinsing under water to prevent sogginess. Slice them evenly for uniform cooking.
  2. Sauté Aromatics: Heat the olive oil and butter in a large skillet over medium heat. Add the chopped onion and sauté for about 5 minutes until translucent and soft. Stir in the minced garlic and cook for an additional 1 minute until fragrant.
  3. Cook the Mushrooms: Add the sliced mushrooms to the pan. Cook, stirring occasionally, until they release their moisture and start to brown, about 8-10 minutes. This step is crucial for developing the rich flavor of the sauce.
  4. Make the Roux: Sprinkle the all-purpose flour over the mushrooms and stir well to coat. Cook for 2 minutes to eliminate the raw flour taste. This mixture will thicken your sauce beautifully.
  5. Add Broth and Herbs: Slowly pour in the vegetable broth while whisking continuously to prevent lumps. Add the thyme and bring the mixture to a gentle simmer. Let it cook for 5-7 minutes until the sauce thickens and coats the back of a spoon.
  6. Finish with Cream: Stir in the heavy cream or plant-based cream, and cook for another 2-3 minutes. Taste and adjust seasoning with salt and black pepper.
  7. Garnish and Serve: Remove from heat and stir in chopped fresh parsley. Serve immediately over your favorite dishes.

Tips & Variations

“For an extra depth of flavor, try adding a splash of white wine during the mushroom sauté step. It adds acidity and brightens the sauce beautifully.”

  • Use Mixed Mushrooms: Combine cremini, shiitake, and oyster mushrooms for a more complex flavor.
  • Vegan Option: Replace butter with olive oil and use coconut or cashew cream instead of dairy cream. Nutritional yeast can add a cheesy depth.
  • Add Soy Sauce or Tamari: A teaspoon can boost the umami notes without overpowering the sauce.
  • Herb Variations: Swap thyme for rosemary or sage to match different flavor profiles.
  • Make it Gluten-Free: Use a gluten-free flour blend or cornstarch slurry as a thickener.
