Ingredients

• 500 grams button mushrooms
• 2 tablespoons olive oil
• 2 tablespoons unsalted butter
• 1 medium-sized, finely chopped onion
• 3 cloves, minced garlic
• 3 tablespoons all-purpose flour
• 2 cups whole milk
• 0.5 cups heavy cream
• 0.5 cups, grated Parmesan cheese
• 1 cups, shredded cheddar cheese
• 1 teaspoon salt
• 0.5 teaspoons black pepper
• 0.5 teaspoons paprika
• 1 cup breadcrumbs
• 2 tablespoons, chopped (optional for garnish) fresh parsley

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a large casserole dish with a bit of butter or oil and set it aside.

Step 2

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

Step 3

Heat a large skillet over medium heat and add the olive oil and butter. Once melted, add the chopped onion and sauté for 3-4 minutes until translucent.

Step 4

Add the minced garlic to the skillet and cook for an additional 1-2 minutes until fragrant.

Step 5

Increase the heat to medium-high and add the sliced mushrooms. Cook for 8-10 minutes, stirring occasionally, until the mushrooms have released their moisture and are golden brown.

Step 6

Sprinkle the flour evenly over the mushrooms and stir well to coat. Cook for 1-2 minutes to eliminate the raw flour taste.

Step 7

Slowly pour in the milk while stirring constantly to create a smooth sauce. Follow with the heavy cream, continuing to stir until the mixture thickens.

Step 8

Reduce the heat to low and stir in the Parmesan cheese, half of the cheddar cheese, salt, black pepper, and paprika. Mix until the cheese has melted and the sauce is smooth.

Step 9

Transfer the mushroom mixture into the prepared casserole dish and spread it out evenly. Top with the remaining cheddar cheese.

Step 10

Sprinkle the breadcrumbs over the top of the casserole for a crunchy topping.

Step 11

Place the dish in the preheated oven and bake for 20-25 minutes, or until the top is golden and bubbly.

Step 12

Remove the casserole from the oven and let it cool slightly before serving. Sprinkle with fresh parsley for garnish, if desired.
