For an extra layer of flavor, consider adding a clove of minced garlic to the skillet along with the onions and mushrooms. Feel free to experiment with different types of mushrooms, such as shiitake or cremini, for a more complex flavor profile. If you don't have half-and-half, you can substitute with whole milk, though the sauce may be slightly less rich. The filled toast cups can be assembled ahead of time and refrigerated until ready to bake. Add a few extra minutes to the baking time if baking from cold. For a vegetarian option, ensure your Parmesan cheese is vegetarian-friendly, as some contain animal rennet.
