Key Ingredients

To bring this healthy breakfast recipe to life, you will need the following key ingredients:

• Turkey bacon: Whenever I’m craving bacon but want to lighten up a dish, I love adding some turkey bacon. It’s lower in calories and fat, yet still super flavorful. Regular bacon also works great. Cooked crumbled breakfast sausage is another delicious option. 
• Eggs: The star of the show! If you want to lighten the dish up even further, you can swap out a few of the eggs for egg whites.
• Milk: You can use any kind of milk you like. Almond, soy, and dairy milk all work well in this dish. For a richer dish, swap in cream or half and half. 
• Shredded cheese: I like to use shredded cheddar cheese in this dish, as it complements the other flavors really well. However, feel free to use any type of shredded or crumbled cheese you like.
• Veggies: A combination of red onions, red bell peppers, and green bell peppers add a ton of flavor and a beautiful pop of color to this dish. Hash browns are another popular choice in an egg casserole. Just defrost them from frozen.

Looking for ways to change up this recipe? Here are some of my favorite variations:

• Switch up the meat. Try swapping out the turkey bacon for another breakfast meat like diced ham, turkey sausage, or chicken sausage.
• Add some Southwestern flair. Try adding some black beans and corn to this dish for added flavor and protein.
• Spice it up. If you’re a lover of spicy food, there are several ways you could spice up this dish. Try adding finely diced jalapenos (like in these Huevos a la Mexicana) to the casserole or drizzling some hot sauce on top just before serving it.
• Swap out the cheese. While I typically use cheddar cheese in this dish, you can use any kind of cheese you like. Some other good options include mozzarella, cotija, monterey jack, and feta cheese.
• Use different vegetables. Feel free to use any kind of veggies you have at home. Some of my favorite choices include broccoli, mushrooms, asparagus, tomatoes, green onions, and spinach.
• Make it even heartier. To make this dish even more hearty and filling, feel free to add black beans, shredded hash brown potatoes, diced potatoes, or diced sweet potatoes.
• Add some fresh herbs. For a ton of added flavor, try adding fresh herbs to the dish either during the cooking process or just before serving it. Great options include cilantro, chives, parsley, and thyme.

How to Store Egg Casserole

This breakfast keeps incredibly well, so it’s the perfect breakfast meal prep recipe. You could easily prep one on a lazy Sunday afternoon and enjoy it over the next several days for a stress-free breakfast. After taking the casserole out of the oven, make sure to let it cool completely before transferring it from the dish.

Once the dish has cooled, you can cut the casserole into slices and place them in an airtight storage bag or container. If you choose to freeze the dish, I recommend storing each slice in a separate bag. Please also keep in mind that the texture of the egg casserole may change in the freezer and become slightly rubbery when thawed.

You can store leftover egg casserole in one of two ways:

• In the fridge for up to 4-5 days.
• In the freezer for up to 2 months.
