A delightful casserole featuring mushrooms in a creamy sauce, topped with a crispy Parmesan crust.
Preheat your oven to 350°F (175°C).
Ensure the oven is fully preheated before placing the dish inside for even cooking.
Arrange the mushrooms evenly in a 2-quart baking dish.
Use an even layer of mushrooms to ensure they cook uniformly.
In a medium bowl, whisk together the beef broth and flour until smooth. Microwave on low power for 2-3 minutes, stirring halfway, until slightly thickened.
Stir the mixture well to avoid lumps.
Stir the heavy cream, cayenne pepper, and salt into the sauce. Mix until well combined.
Taste the sauce and adjust the seasoning if needed.
Pour the sauce evenly over the mushrooms in the baking dish.
Ensure the sauce covers all the mushrooms for even flavor.
In a medium bowl, mix the breadcrumbs and Parmesan cheese. Sprinkle this mixture over the mushrooms.
For a more flavorful topping, add a pinch of garlic powder or Italian seasoning.
Dot the topping with butter pieces. Bake in the preheated oven for 45 minutes, or until the top is golden and bubbly.
Check the casserole halfway through baking to ensure the topping doesn't burn.
Let the casserole cool for a few minutes before serving. Enjoy your delicious creation!
Serve with a side salad or crusty bread for a complete meal.
