Recipe Information
Ingredients
- 500 grams button mushrooms
- 1 medium onion
- 3 garlic cloves
- 3 tablespoons butter
- 3 tablespoons all-purpose flour
- 2 cups milk
- 1 cup vegetable broth
- 1.5 cups shredded cheddar cheese
- 1 cup breadcrumbs
- 1 tablespoon olive oil
- 1 teaspoon salt
- 0.5 teaspoon black pepper
- 2 tablespoons fresh parsley
Instructions
Preheat the oven to 375°F (190°C). Grease a 9x13 inch casserole dish with a small amount of butter or olive oil.
Wash the mushrooms thoroughly, pat them dry, and slice them thinly. Dice the onion and mince the garlic cloves.
Heat 2 tablespoons of butter in a large skillet over medium heat. Add the onions and sauté for 3-4 minutes until translucent.
Add the garlic and mushrooms to the skillet. Cook for 5-7 minutes, stirring occasionally, until the mushrooms are golden brown and most of the liquid has evaporated. Remove from the heat and set aside.
In a medium saucepan, melt the remaining 1 tablespoon of butter over medium heat. Stir in the flour and whisk continuously for 1-2 minutes to create a roux.
Gradually add the milk and vegetable broth to the roux, whisking constantly to prevent lumps. Cook the mixture for 4-5 minutes, or until it thickens into a smooth, creamy sauce.
Season the sauce with salt and black pepper. Stir in 1 cup of shredded cheddar cheese until melted and fully incorporated.
In a large mixing bowl, combine the sautéed mushrooms and onions with the cheese sauce. Mix well to coat all the ingredients evenly.
Transfer the mixture to the prepared casserole dish and spread it out evenly.
In a small bowl, mix the breadcrumbs with the olive oil. Sprinkle the breadcrumb mixture evenly over the casserole, followed by the remaining 0.5 cup of shredded cheddar cheese.
Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and bubbling.
Remove the casserole from the oven and let it rest for 5 minutes. Garnish with freshly chopped parsley before serving.
