This Mexican Breakfast Casserole is packed with so much flavor and goodness. It might just be one of my favorite breakfast casseroles ever. Perfect for breakfast, brunch or dinner!
You guys, I have made a lot of breakfast casseroles in my day, and I’m not trying to brag or anything, but this Mexican Breakfast Casserole is pretty amazing! Some of my boys have declared it their new favorite. I think once you try this scrumptious casserole, you might be saying the same thing.
We love this tater tot breakfast casserole and it still ranks right up at the top for all of us, but we’re really loving this Mexican casserole right now. About 99% percent of the time I throw salsa on top of my breakfast casserole, so I thought why not add a layer of salsa right into the casserole. Turns out it is amazing and takes breakfast casserole to a whole new level.
With General Conference this weekend, I’ll be making big breakfast spreads both Saturday and Sunday mornings. If you will be too, then you need to give this casserole a try. You’re going to love it.
HOW SPICY IS THIS?
It all depends on the salsa you use. If you want this to be on the super hot side, then use your favorite hot salsa. You can also use pepper jack cheese in place of the colby jack if you’re wanting even more kick. But if you’re a little bit of a whimp like me when it comes to heat level in foods, then go for a more mild salsa.
CAN THIS MEXICAN BREAKFAST BE MADE AHEAD OF TIME?
Yes, absolutely. You can assembly the entire casserole and then cover it with foil and put it in the fridge overnight. When you’re ready to eat, just uncover it and throw it in your preheated oven and let it cook according to the directions. It may need an extra 5 or 10 minutes, so just keep an eye on it.
THERE IS SO MUCH TO LOVE ABOUT THIS CASSEROLE . . .
- It’s simple to throw together last minute, but it can also be made ahead of time.
- It’s hearty, filling and loaded with so many good things.
- It’s a delicious and fantasic change of pace from your usual breakfast casserole.
- It reheats beautifully and makes the best leftovers.
Top it with sour cream, avocado, fresh cilantro, more salsa, etc., or keep it simple and just eat it as is. However you decide to garnish it, it’s going to be delicious.

This was tasty and we all enjoyed it! I love salsa on my eggs. My husband was afraid 2 cans of the green chilies would be spicy for our 8 & 10 year old but it wasn’t. I want to make this again but will add both cans next time. May add a little more salsa too. My husband thought it was more of a potato casserole with egg and not the other way around since there was a lot of potatoes. Next time I would add half the amount of potatoes. Looking forward to making more of your recipes. I love your photography as well!

Hi Jacqueline! I’m glad you liked this and that you know what you’d tweak next time to fit your tastebuds. We love it as is, but everyone likes things differently. Thanks for the kind words about my recipes and especially my photography (I am my own worst critic and think my photos are only so-so), you really made my day. Stay safe and healthy! xoxo
