You can add vegetables like bell peppers, zucchini, or artichoke hearts for added flavor and nutrition. Just sauté them along with the mushrooms for a delicious twist.
Is it possible to make this casserole ahead of time?
Absolutely! You can prepare the casserole, assemble it, and refrigerate it for up to 24 hours before baking. Just add a few extra minutes to the baking time if it's coming straight from the fridge.
