Ingredients

• 500 grams Button mushrooms
• 1 medium Onion
• 2 tablespoons Butter
• 1 tablespoon All-purpose flour
• 200 milliliters Heavy cream
• 100 milliliters Chicken or vegetable stock
• 0.25 teaspoons Nutmeg
• 0.5 teaspoons Salt
• 0.5 teaspoons Black pepper
• 100 grams Gruyère or mozzarella cheese, grated
• 2 tablespoons Fresh parsley, chopped (optional)
• 2 tablespoons Bread crumbs (optional)

Directions

Step 1

Preheat the oven to 200°C (400°F).

Step 2

Clean the mushrooms with a damp paper towel and slice them thinly. Dice the onion into small pieces.

Step 3

In a large skillet, melt the butter over medium heat. Add the diced onion and cook until translucent, about 2–3 minutes.

Step 4

Add the sliced mushrooms to the skillet and sauté until they release their moisture and turn golden, about 5–7 minutes.

Step 5

Sprinkle the flour over the mushrooms and onions, stirring well to coat evenly. Cook for 1 minute to remove the raw flour taste.

Step 6

Slowly pour in the chicken or vegetable stock, stirring constantly to avoid lumps. Follow with the heavy cream, and stir until the sauce thickens, about 2 minutes.

Step 7

Season the mixture with nutmeg, salt, and black pepper to taste. Remove the skillet from the heat.

Step 8

Transfer the mushroom mixture to a greased casserole dish or individual ramekins for serving.

Step 9

Sprinkle grated cheese evenly over the top. For extra texture, you can add bread crumbs over the cheese.

Step 10

Bake in the preheated oven for 15 minutes, or until the cheese is melted and bubbly with a golden crust.

Step 11

Remove from the oven and let cool for 5 minutes before serving.

Step 12

Garnish with fresh parsley, if desired, and serve warm as an appetizer or a side dish.
