A quick and comforting casserole combining tender beef, mushrooms, sour cream sauce, and a crispy cheese crust, perfect for cozy dinners and busy weeknights.
For extra crispy cheese crust, broil the casserole for 1-2 minutes at the end but watch carefully to avoid burning. To make gluten-free, substitute flour with cornstarch and use gluten-free noodles. For dairy-free, use coconut cream or plant-based sour cream and replace cheese topping with a breadcrumb and nutritional yeast mix. Let casserole rest before serving to thicken sauce and ease scooping. Can be assembled a day ahead and refrigerated; add a few extra minutes to baking time if chilled.
