Ingredients
  

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

Instructions
 

  • Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish to prevent sticking.
  • In a mixing bowl, combine sliced mushrooms with olive oil, garlic powder, thyme, salt, and pepper. Toss to coat the mushrooms evenly.
  • Spread the seasoned mushroom mixture evenly across the bottom of the prepared baking dish.
  • Sprinkle shredded cheddar and grated Parmesan cheese evenly over the mushrooms, creating a cheesy layer.
  • Pour the heavy cream evenly over the mushrooms and cheese, which will form a creamy sauce as it bakes.
  • In a separate bowl, combine melted butter with breadcrumbs, stirring until well mixed. Sprinkle this breadcrumb mixture over the top of the casserole.
  • Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and the sauce is bubbling around the edges.
  • For an extra crispy topping, broil the casserole for an additional 2-3 minutes after baking. Watch closely to avoid burning.
  • Let the casserole rest for a few minutes. Garnish with freshly chopped parsley before serving.

Notes

For an added twist, try mixing in chopped spinach with the mushrooms before baking.
