Wisconsin Brunch Casserole with Ham and Mushrooms

This make-ahead Wisconsin brunch casserole is made with ham, bread, mushrooms, eggs, milk, and cheddar cheese. It is a quick and easy casserole that your friends and family will love.

Okay, this is a get down to basics kind of recipe. The ingredients are ones you almost always have around the house and the seasonings are basic too. That is why I named this a Wisconsin brunch casserole. It offers some of the best flavors of Wisconsin and Midwest cooking. Just basic good food.

I love how easy this is to make. Simply prepare all of your ingredients the night before, refrigerate, and bake in the oven the next morning. That can make your life a bit easier if you have guests staying the night. I have also made this for an evening dinner too because you can make it earlier in the day if you know you will be out of the house. When you come home, just bake it in the oven and you will have dinner on the table.
