Step-by-Step Instructions

- Bake:

Cheese has always been my favorite part of this casserole I love using a sharp cheddar or even tossing in a handful of pepper jack for a kick. Every year my daughter puts her own twist with colorful bell peppers and we laugh about who melts the cheese the best that year. Nothing beats seeing everyone reach for a second slice.
Storage Tips
Cover leftovers tightly and refrigerate for up to four days sliced or whole this casserole reheats well simply microwave individual pieces or warm in a low oven with a splash of milk to revive moisture. For freezing wrap slices tightly in foil and store in a freezer-safe bag up to two months thaw overnight before reheating.
Ingredient Substitutions
No sausage on hand try cooked crumbled bacon or even ground turkey for a lighter twist. If bread is not your thing skip it for a crustless version or use hash browns for an extra comfort factor. Dairy-free milk and cheese swaps also work here just aim for unsweetened options for best taste.
Serving Suggestions
Pair a warm slice with a simple fruit salad or roasted potatoes for a more filling brunch. Add hot sauce or a dollop of sour cream to jazz up each plate. For dinner nights I love to serve it alongside a crisp green salad and maybe some biscuits on the side for that homemade touch.
