Back-to-school season is one of the busiest times of year in my home. These Make Ahead Breakfast Casserole Cups are the perfect grab-and-go meal for busy school mornings. Cereal used to be my go-to for breakfast convenience. Unfortunately, those carbs get burned up by my kids’ young metabolisms well before lunch arrives. So, I had to find a way to pack some protein into their morning meal to help stave off hunger longer. I can make these Make Ahead Breakfast Casserole Cups on the weekend and freeze them so the kids can reheat them for breakfast during the week.
