For a vegetarian option, substitute the Italian sausage with plant-based crumbles or additional mushrooms. Feel free to experiment with different types of cheese. Gruyere or Fontina would also be delicious in this casserole. To add a touch of heat, incorporate a pinch of red pepper flakes into the mushroom mixture. The casserole can be assembled ahead of time and refrigerated for up to 24 hours before baking. Add an extra 10-15 minutes to the baking time if baking from cold.
