    I absolutely adore this breakfast casserole! It’s such a versatile dish that can be adapted to fit your needs. You can substitute ham or bacon for the sausage or can swap in different veggies depending on what you have on hand. So easy and customizable!

    I also love it because you can prepare the easy breakfast casserole the day before, refrigerate it overnight and then pop it in the oven on a holiday morning. We love to serve it for Easter and Christmas brunch. So yummy and very filling!

    This breakfast casserole recipe has tons of flavor…especially from the breakfast sausage and green chiles. They really help to take the taste up a notch. Some of the breakfast casserole recipes that I’ve tried before are kind of bland, but this sausage breakfast casserole is anything but that!

    Frequently asked questions for breakfast casserole

    Do you cover breakfast casserole when baking? Yes, I cover with aluminum foil for the first 45 minutes of baking, then remove the foil and cook for an additional 10 to 15 minutes without it.

    How do you know when breakfast casserole is done? Your breakfast casserole is done when the outside edges are slightly golden and the egg mixture stays firm when you gently rock the pan from left to right. You want to make sure the egg mixture has cooked all the way through and isn’t still liquefied in the center. To double check, stick a knife in the middle of the casserole. The knife should come out clean if cooked completely.

    How long does breakfast casserole last in fridge? This breakfast casserole will keep in the fridge for about 3-4 days. Make sure to cover your pan with a lid or wrap tightly in aluminum foil or plastic wrap.

    Can you reheat a breakfast casserole? Yes. To reheat, you can either warm for a few minutes in the microwave or the oven. If using the oven, I would recommend covering with foil.
