Toppings and Recipe Variations

• Veggies - Add any extra vegetables of your choosing. I recommend giving them a quick saute in olive oil to soften them a bit and remove some moisture before baking. Some great vegetables to add are bell pepper, jalapenos, onion, spinach, zucchini, or asparagus.
• Meats - The recipe calls for ground sausage, but you can add or substitute with bacon, ham, Canadian bacon, or ground turkey. You can also omit the sausage and just add veggies, mushrooms and beans!
• Mushrooms - Sauteed mushrooms are excellent in this dish if you love mushrooms. Just before to saute until tender before stirring into the egg mixture.
• Beans - I love adding a can of drained and rinsed beans to casseroles because it bulks up the meal in a super healthy way, making it more filling with extra protein and fiber!
• Cheese - Cheddar is the cheese of choice in this recipe. Experiment with your own favorite cheese such as mozzarella, gouda, Swiss, or pepper Jack.
• Herbs - Fresh herbs such as parsley, sage, thyme, or chives add a beautiful, fresh element to a classic casserole. Mix them right into the egg mixture or sprinkle some on top before serving.
• Toppings - Add a little more flavor with toppings as a finishing touch like salsa, hot sauce, avocado, more fresh herbs, green onion, sausage gravy,or sawmill gravy.

Yes! One of the best parts about this dish is that you can prep it up to 24 hours in advance, and even freeze it for later!

To make your casserole ahead of time, assemble the casserole, cover and refrigerate up to 24 hours in advance. Bake for an additional 10 minutes to account for the cold dish and casserole.

To freeze your casserole, prepare casserole through step 7. Then cover tightly and freeze for up to 3 months. Thaw overnight in the refrigerator. Bake for an additional 10 to 15 minutes, or until completely cooked through, to account for the cold dish and casserole.
