Ingredients

• 230 grams Portabella mushrooms
• 2 tablespoons Unsalted butter
• 1 tablespoon Olive oil
• 2 pieces Garlic cloves, minced
• 1 piece Shallot, finely chopped
• 1 tablespoon All-purpose flour
• 240 milliliters Chicken or vegetable stock
• 120 milliliters Heavy cream
• 1 teaspoon Fresh thyme leaves
• 0.5 teaspoon Salt
• 0.25 teaspoon Black pepper, freshly ground
• 30 grams Parmesan cheese, grated (optional)

Directions

Step 1

Clean the portabella mushrooms with a damp paper towel and slice them thinly.

Step 2

In a medium-sized skillet, heat the olive oil and 1 tablespoon of butter over medium heat.

Step 3

Add the sliced mushrooms to the skillet and sauté for 5-7 minutes, stirring occasionally, until they release their liquid and begin to brown lightly.

Step 4

Add the minced garlic and chopped shallot to the skillet and cook for an additional 2 minutes, until fragrant.

Step 5

Sprinkle the flour over the mushrooms and stir well to coat. Cook for 1 minute to eliminate the raw flour taste.

Step 6

Gradually pour in the chicken or vegetable stock while stirring constantly to avoid lumps. Bring the mixture to a gentle simmer.

Step 7

Stir in the heavy cream, thyme leaves, salt, and black pepper. Simmer for 5 minutes, stirring occasionally, until the sauce thickens to your desired consistency.

Step 8

If using, stir in the grated Parmesan cheese until melted and well incorporated.

Step 9

Remove the skillet from heat and stir in the remaining tablespoon of butter to enhance the sauce's richness and shine.

Step 10

Serve immediately over steak, pasta, mashed potatoes, or roasted vegetables. Enjoy!
