Ingredients

Scale

Main Ingredients:

  • 1 lb (454 g) button mushrooms, sliced
  • 1 cup shredded cheddar cheese
  • 1/2 cup grated Parmesan cheese
  • 1 cup heavy cream

Seasoning Ingredients:

  • 1 tablespoon olive oil
  • 1 teaspoon garlic powder
  • 1 teaspoon dried thyme
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper

Finishing Ingredients:

  • 2 tablespoons unsalted butter, melted
  • 1/2 cup breadcrumbs (optional)
  • Fresh parsley, chopped (for garnish)

Instructions

  1. Prepare oven space by heating to 375°F and coating a 9×13 inch baking dish with light grease to prevent sticking.
  2. Create a flavor base by thoroughly mixing sliced mushrooms with olive oil, garlic powder, thyme, salt, and pepper in a mixing bowl, ensuring each mushroom slice is evenly seasoned.
  3. Distribute the seasoned mushroom mixture uniformly across the prepared baking dish, creating an even layer that allows for consistent cooking.
  4. Generate a rich cheese layer by scattering shredded cheddar and grated Parmesan cheese generously over the mushroom foundation, covering the entire surface.
  5. Enhance the dish’s creaminess by drizzling heavy cream systematically across the cheese and mushroom layer, promoting a smooth and luxurious texture.
  6. Craft a crispy topping by combining melted butter with breadcrumbs until fully integrated, then sprinkle this mixture evenly over the casserole surface.
  7. Transfer the prepared casserole into the preheated oven and bake for 25-30 minutes, monitoring until the top turns golden brown and the sauce begins to bubble around the edges.
  8. Optional: For an extra crisp finish, activate the broiler and cook for an additional 2-3 minutes, watching carefully to prevent burning.
  9. Allow the casserole to rest briefly after removing from the oven, which helps stabilize the sauce and intensify flavors.
  10. Finish by garnishing with freshly chopped parsley, adding a vibrant touch of color and fresh herb essence before serving.

Notes

  • Use fresh, high-quality mushrooms for the most robust flavor and best texture in the casserole.
  • Select a mix of mushroom varieties like cremini, shiitake, or button mushrooms to add depth and complexity to the dish.
  • Pat mushrooms dry before seasoning to prevent excess moisture and ensure proper caramelization during baking.
  • Choose sharp cheddar and freshly grated Parmesan for maximum cheese flavor and creamy consistency.
  • Experiment with gluten-free breadcrumbs or crushed nuts for a low-carb or celiac-friendly alternative topping.
  • Allow the casserole to rest briefly after baking, which helps the sauce set and intensifies the overall flavor profile.
