Who doesn’t love a delicious hot breakfast in the morning without any work?! I LOVE, love, love this overnight breakfast casserole. You throw it together the night before, and then you stick it in your fridge until morning. In the morning you simply pop it in the oven for an hour and, viola, the yummiest breakfast casserole, without any work or fuss!

Start by lining the bottom of a 9×13” pan with slices of white bread. (I’ve found that plain old white sandwich bread works best for soaking up the liquid from the casserole).

Top the bread with fresh grated cheese. I use Colby jack, but feel free to experiment with your favorite kind of cheese!

Add browned sausage, onions, bell peppers and green chiles on top. The green chiles add great flavor, and a little bit of spice. Feel free to substitute a mild salsa.

Next, mix the eggs, milk and spices in a bowl. Pour the mixture over the casserole. Cover it with plastic wrap, or a lid, and refrigerate until morning.  Bake it in the morning until the top is set. The center may look a little soft, which is fine. It will continue to cook and set up as it cools.Two side-by-side photos for the process of making a breakfast casserole, starting with eggs being whisked in a bowl, and the next of the egg mixture being poured over a 9x13'' pan of with bread, cheese, sausage and veggies.
This is the perfect breakfast casserole for times holidays, Christmas morning, wedding or baby showers, or any other occasion where you might have company or want to relax in the morning. Heck, I’d even make this for a regular morning, just because it tastes so good and the leftovers taste great reheated, for several days.

I also love this recipe because it’s really easy to adapt to what you like. You can add more veggies, or different veggies, like mushrooms or spinach. You could substitute salsa, for the green chiles, or use your favorite kind of cheese. I like to serve it with avocado slices, to balance out the flavors. Hope you enjoy it!

    How far in advance can this be made/put together? Can you prep and refrigerate longer than overnight—day a day or so—before baking?

      It would probably be fine to make 2 days in advance. Or you can bake it and reheat it.

    Going to try this today!! I’m hoping that I don’t make ahead to early and it doesn’t turn out! I want to have it prepared by noon then bake it tomorrow morning! Do you think that’s too long for it to sit in fridge?

    H! Ive made this at least 3 times in one month. It’s a hit with everyone who tries it and they want the recipe.
    This time, I only have wheat bread that is a significantly denser than regular white bread. Do you think it will still work? Wondering if it would soak in the egg mixture as well.

      I’m really happy to hear that! Yes I think the wheat bread would work fine–the texture of the casserole may be a little thicker but I think it will taste great 🙂

    Wonderful! Finally, a breakfast casserole that adds a few more spices besides salt and pepper. I love the fact that there is more color and therefore more nutrition in this dish (thanks to veggies). I used texas toast and I think next time I will cube the bread and blend the ingredients a little more. Layers are good, but sometimes I think it looks to flat. Nice job!

    Would it be okay to make this in a tin 9×13 pan? I want to make it ahead but I will be camping and don’t want to bring my nice Pyrex. Thanks!

    I made this recipe and followed the directions. It turned out amazing. I was wondering if I could substitute the bread for hash browns and hoping this might still work. Any thoughts on that?
