This Roasted Veggie Breakfast Casserole is the marriage of a sheet pan dinner with a breakfast casserole. Simply repurpose roasted veggies from one meal into another. My family loves this delicious, healthy meal served with a side salad for brunch, breakfast, or even dinner!
Preheat oven to 375ºF and grease or spray 9x9" (or other similar size) baking dish with oil or cooking spray.
Place some of the roasted vegetables evenly in the bottom of the casserole dish. Pour in egg mixture. Add additional roasted vegetables, of desired amount, to the top of the egg mixture.
