If you’re bored of the same ol’ breakfast every morning, I feel your pain. Protein shakes, cereal, and oatmeal get old after a while.

Lately, I wake up in the morning hankering for something slightly out of the norm.

If I think about what I’m craving long enough several things repeatedly come to mind… Eggs, hot cheesy goodness, spice, and a soft-crispy textural balance. That is a combination I could never get tired of.

So after fantasizing over the perfect breakfast for days and days, I finally have a recipe to share that fits the bill.

Today’s savory Mexican Breakfast Casserole with Crispy Hash Brown Top is a morning breakfast bake I can’t seem to get enough of, and neither can anyone else who’s tried it. Fluffy eggs and tortillas, molten cheese, red peppers, green chiles, and a crispy golden crust that rivals the brilliance of the rising sun.

This is a breakfast worth getting up for in the morning.

Making Mexican Breakfast Casserole with Hash Brown Top! #breakfast #casserole

My Mexican Breakfast Casserole with Hash Brown Top starts with a simple mixture of eggs, cheese, and chopped flour tortillas.

Then I added onions, red bell pepper, and spicy Old El Paso Green Chiles for flavor. The chiles give the breakfast casserole spicy Mexican appeal, while the tortillas absorb some of the moisture and help the casserole puff up in the oven.

Mixing tender Old El Paso Flour Tortillas into the the mixture also serves another purpose. It gives the egg mixture stability, so it can hold up the amazing golden hash brown crust!

For the Hash Brown Top, I combined thawed hash brown potatoes with Old El Paso Taco Seasoning and melted butter. The taco seasoning coats the shredded potato giving it zesty flavor and color. While the butter ensures the topping crisps in the oven.

    Quick question: can this be made late in the afternoon and refrigerated for baking and serving the next morning for brunch?

    It looks amazing!

      Hi Sara,

      Yes, it can be prepped ahead! However, I would still add the hash brown layer right before baking.

    Great Mexican casserole! I’m a big fan of Mexican food – this one with cheese and eggs is so tempting than the usual breakfast with just vegetables. I’m gonna try it right now. I’m sure it’s going to be awesome.

    Made this twice for large groups and loved it!  So much easier to put together and slice and serve than a traditional bread based breakfast casserole.  A very small amount leftover, I cut into little squares and they reheated perfectly.  Did not mix the taco seasoning in with the potatoes, instead added Johnny’s seasoning salt and it still gave it nice color and flavor, the chiles, red pepper, onion and fresh salsa I served with gave it plenty of Tex-Mex zing.  Thanks for yet another great recipe Sommer!

    This was really tasty. It just needed black pepper, a bit more salt and one more can of chillies. Perhaps some cheese mixed in with the hash browns??
