Mexican Breakfast Casserole is an overnight breakfast casserole, packed with flavor from salty, juicy chorizo, creamy eggs, and gooey cheese!
Mexican Breakfast Casserole
I'm a savory kind of girl. I almost always opt for savory over sweet, especially for breakfast. And this Mexican Breakfast Casserole hits that savory, spicy, cheesy spot.
It's flavorful and unique, and best of all, it's an overnight casserole, so you throw it together the night before, then pop it in the oven in the morning. Nothing better than waking up to a warm, tasty breakfast!
This Mexican Breakfast Casserole is packed with bold flavors like salty chorizo, creamy scrambled eggs, and gooey cheese. Topped with fresh pico de gallo and avocado, it makes an amazing breakfast.
How to Make a Vegetarian Mexican Breakfast Casserole
To make your casserole vegetarian, simple substitute a can of black beans. Black beans are probably my favorite way to make any meal meatless.
Use a can (15 ounce) can of black beans, drained and rinsed, and a can of corn, drained, instead of the chorizo. Saute with the onion and bell pepper, then add a tablespoon of chili powder. Continue with the recipe, as written.
How to Freeze Mexican Breakfast Casserole
To freeze your Mexican Breakfast Casserole, simply follow steps 1-4 of the recipe. Then cover and freeze in a freezer-safe dish for up to 3 months.
When ready to use, allow to thaw in the refrigerator overnight. Then finish the recipe as instructed.

Mexican Breakfast Casserole
Ingredients
- 1 pound chorizo sausage
- ½ large onion finely chopped
- ½ red bell pepper finely chopped
- 5 cloves garlic minced
- 8 ounces Pepper Jack cheese shredded
- 8 ounces cheddar cheese shredded
- 4 green onions finely sliced
- ¼ cup cilantro finely chopped
- 2 jalapeno peppers seeded, deveined, and finely chopped
- 12 large eggs
- 3 cups half-and-half
- ½ teaspoon hot sauce
- ½ teaspoon ground black pepper
- 9 corn tortillas quartered
- Toppings: Pico de gallo, sour cream, and avocado or guacamole
Instructions
- In a large skillet, brown chorizo with onions, bell peppers, and garlic until chorizo is cooked through. Remove from heat, and set aside.
- In a medium mixing bowl, combine cheeses, cilantro, green onions, and jalapenos. Stir until combined. Set aside.
- Butter a 9"x13" baking dish.
- Spread a third (⅓) of the tortilla pieces into the bottom of the dish (12 pieces). Then spoon ⅓ of the chorizo mixture and ⅓ of the cheese mixture on top. Repeat layers twice more, ending with the cheese layer.
- In a separate large mixing bowl, whisk together eggs, half & half, hot sauce, and black pepper until fully combined and a little bit bubbly. Pour egg mixture on top of tortilla layers.
- Cover and refrigerate for at least 6 hours or overnight.
- Bake at 350° for 60-90 minutes, until golden brown. You can test done-ness the same way you would with a cake. Simply insert a fork, and if it comes out clean it's ready.
- Let set for 10 minutes before serving. Serve with fresh pico de gallo, sour cream, and avocado.
Notes
- Serve this casserole with all your favorite taco toppings, like pico de gallo, sour cream, guacamole, fresh avocado, salsa, cilantro, hot sauce, you name it! I highly HIGHLY recommend serving it with this fresh pico de gallo as the acidity from the tomato and lime juice goes with the earthy saltiness of the chorizo and makes this dish truly amazing!
- Mexican Breakfast Casserole is naturally gluten free (double check your sausage. Some chorizo has gluten additives in it!).
- Can you use milk instead of half-and-half? Yes, but use whole milk if you can. The fat in the half-and-half adds to the silky texture, which won't really be found in milk with less fat than whole milk.
- Can I use flour tortillas? Absolutely. We use the exact same technique and don't really notice a flavor difference at all.
- Do you really have to let it chill for 6 hours?! You can cook it right away or after only a couple of hours. However the extra chill time allows the eggs to get into the tortillas, making them moist and almost flaky when you bake it. It will bake fine if you don't let it chill all night, but it's better if you do!
- Salt. You might notice there isn't any added in this recipe! That's because chorizo is naturally pretty salty, so I don't find it necessary to add any more.
- To store: Cover and refrigerate for up to 4-5 days. Reheat leftovers in the microwave.

Hi Michelle,
you say Chorizo sausage, is this the hard already cooked chorizo, or do you use the soft crumbly chorizo? I will be making this weekend, but need to know which chorizo you are referring to. Thanks
Michelle says
This is uncooked sausage. It usually comes in a tube and is pretty mushy when you take it out of the package.
Tasha Lamoureux says
This looks amazing! We do a lot of breakfast for dinner in our house, so I'm going to prep this first thing tomorrow morning! I was just curious, does the size of the tortillas matter? I have large, burrito sized tortillas in my fridge already. TIA and thank you for this great new recipe to try!
Michelle says
I don't think it would matter. I might just cut them down to make them easier to work with though.
Dara says
Hello! Has anyone made this without the tortillas? Do they make a huge difference?

Rylie says
Hi, do you think I could make this on a Thursday night and bake it on Saturday morning? Would that be too much time in the fridge? Would it ruin it at all?
Michelle says
You can prep all of the ingredients except the egg mixture and assemble it. Then whip the egg mixture up really quick Friday night or Saturday before you bake it.
Jalene says
Made this for my nieces graduation brunch and everyone loved it. I plan on making it again for my sister, who was unable to be at her baby’s graduation. I did have one question can this be frozen?
Michelle says
I would not recommend freezing this particular casserole. What you can do is prep all the ingredients ahead of time, and even layer it up without the eggs a couple days before. Then just whip up the eggs and add them before baking.
TJ says

Yes! So yummy for weekend breakfast! Glad you liked it!

Mary Campbell says
Can this be refrigerated overnight or 6 hours only?
Brenda Thomas says
Should it be covered when baked? I thought I saw this question asked previously but didn’t see a response.
Michelle says
Nope, you don't need to cover when baking. I just cover it while it's chilling in the refrigerator.
JP Buttercup says

sue says
can you make this without tortillas?
Michelle says
Maybe but I've never tried it, so I'm not sure about cook times. You can use this ham breakfast casserole with no bread or tortillas for cook time references, and hopefully that will work! Let us know how it goes!

Kara Robinson says
When freezing, it says to do steps 1-4. That doesnt include adding the eggs. Should I add them the night before so the tortillas can absorb them?
Michelle says
Yes, that's correct!
Becky Baudouin says
This recipe is the BOMB!! The corn tortillas make this so delicate and delicious. It’s a tradition now at our girls’ weekend!
