Ingredients
  

  • 1 lb button mushrooms sliced
  • 1 tbsp olive oil
  • 1 tsp garlic powder
  • 1 tsp dried thyme
  • 1/2 tsp salt
  • 1/4 tsp black pepper
  • 1 cup shredded cheddar cheese
  • 1/2 cup grated Parmesan cheese
  • 1 cup heavy cream
  • 2 tbsp unsalted butter melted
  • 1/2 cup breadcrumbs optional
  • fresh parsley chopped, for garnish

Instructions
 

  • Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
  • In a bowl, toss the sliced mushrooms with olive oil, garlic powder, thyme, salt, and pepper until well coated.
  • Spread the mushroom mixture evenly in the prepared baking dish.
  • Sprinkle the shredded cheddar and grated Parmesan over the mushrooms.
  • Pour the heavy cream evenly over the entire dish.
  • In a separate bowl, mix the melted butter with breadcrumbs until well combined. Sprinkle this mixture over the top of the casserole.
  • Bake in the preheated oven for 25-30 minutes, until the top is golden brown and the sauce is bubbling.
  • Optionally, broil for an additional 2-3 minutes to achieve an extra crispy topping.
  • Let the casserole rest for a few minutes before garnishing with chopped parsley and serving.
