Ingredients

• 500 grams Button mushrooms
• 3 tablespoons Butter
• 2 tablespoons All-purpose flour
• 1.5 cups Milk
• 0.5 cups Heavy cream
• 2 cloves Garlic
• 1 small Yellow onion
• 0.5 cups Grated Parmesan cheese
• 1 cups Shredded Gruyère cheese
• 1 teaspoon Salt
• 0.5 teaspoons Ground black pepper
• 0.75 cups Breadcrumbs
• 1 tablespoon Olive oil
• 2 tablespoons Chopped fresh parsley (optional for garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C) and grease a medium-sized baking dish.

Step 2

Clean the mushrooms with a damp cloth or paper towel to remove dirt, then slice them thinly.

Step 3

Peel and finely mince the garlic. Finely dice the onion.

Step 4

In a large skillet, melt 2 tablespoons of butter over medium heat. Sauté the onions and garlic until they are soft and fragrant, about 3-4 minutes.

Step 5

Add the sliced mushrooms to the skillet and cook for 5-7 minutes, stirring occasionally, until they are tender and their moisture has mostly evaporated. Season with 1/2 teaspoon of salt and 1/4 teaspoon of black pepper. Set aside.

Step 6

In a medium saucepan, melt the remaining 1 tablespoon of butter over medium heat. Whisk in the flour, cooking for 1-2 minutes to create a roux.

Step 7

Slowly pour in the milk, whisking constantly to prevent lumps. Cook until the mixture thickens, about 3-4 minutes.

Step 8

Add the heavy cream to the saucepan and stir. Reduce the heat to low, then mix in the Parmesan cheese and 1/2 cup of Gruyère cheese, stirring until melted and smooth.

Step 9

Combine the cooked mushrooms and onions with the cheese sauce, then pour the mixture into the prepared baking dish.

Step 10

In a small bowl, mix the breadcrumbs with the olive oil, remaining Gruyère cheese, and a pinch of salt and black pepper. Sprinkle the breadcrumb mixture evenly over the mushrooms in the baking dish.

Step 11

Bake uncovered in the preheated oven for 20-25 minutes, or until the top is golden brown and bubbling.

Step 12

Remove the dish from the oven and let it cool for 5 minutes. Garnish with freshly chopped parsley if desired, and serve warm.
