Sometimes, you need a healthy make-ahead breakfast. Whether you’re serving a crowd or trying to ease busy weekday mornings, this breakfast casserole is just the ticket. Typically, breakfast casseroles includes sausage and potatoes. I loaded this one up with fresh veggies and greens instead, including red bell pepper, green onion and spinach. Creamy feta or goat cheese rounds it all out. You don’t need a ton of dairy to achieve a lovely, luxurious texture. This is a lightened-up dish that seems more indulgent than it really is.
This healthy breakfast casserole is the perfect addition to a holiday breakfast spread. Since it offers some protein and vegetables, it’s a great way to help balance those delicious carb-heavy treats, like muffins and pancakes. I’d be thrilled to find this option alongside bagels and cream cheese. Leftovers are good for lunch, too. To develop this recipe, I followed my foolproof frittata formula. It’s easy to make, colorful and delicious!

How to Prepare This Casserole in Advance
Prepare the mixture as instructed, but refrigerate the egg and veggie mixture in a mixing bowl or in the buttered baking dish for up to two days. Bake as directed, knowing that your dish may require a few extra minutes in the oven since it’s starting off cold (especially if you refrigerated in the baking dish).

Please let me know how your breakfast casserole turns out in the comments! I love hearing from you.
Change it up: I love the flavors you see here, but you can definitely use other vegetables in similar quantities. More hardy greens like kale or chard will require a bit more cooking time. Find other flavor variations on my frittata post. Can I freeze it? I don’t recommend freezing leftover breakfast casserole. When I defrosted my frozen slices, they turned very watery and slightly rubbery. If you’re looking for a good egg-based freezer recipe, check out my breakfast burritos.
