Enjoy all the flavors of sunrise in one great-tasting dish—our overnight breakfast casserole recipe doesn’t just feed the crowd—it’ll feed your soul, too! Breakfast sausage, onion, bell peppers, hash browns, egg and cheese…is your mouth watering yet?
As the name of this casserole implies, it’s prepared the night before then placed in the refrigerator until you’re ready to pop it in the oven. This is especially helpful when you have a house full of people for the holidays or special occasions.
If you like a little spice, add diced green chiles and swap the cheddar for pepper Jack if you want the heat to come from the inside. Otherwise, serve with red pepper flakes and hot sauce on the side. And while we’re on the topic of adding and substituting flavors—swap the sausage for ham, bacon or extra veggies. Yeehaw!
