Breakfast casseroles are a busy girl’s morning savior. Since we are always running behind in the morning, having this southwest breakfast casserole prepared ahead of time means that my family can still enjoy a warm, hearty, protein-filled breakfast without any last-minute cooking stress.
This Mexican breakfast casserole recipe is built in repeating layers, starting with a base of low carb tortillas that are topped with ground sausage, onion and bell peppers seasoned with a spicy Southwest blend of chili powder, garlic powder and cumin. Shredded Mexican blend cheese is generously sprinkled on top. Finally, whisked creamy eggs are poured on top to serve as the binder for the other ingredients and then baked into an easy, make ahead casserole that my family can’t get enough of!!
What makes this egg breakfast casserole stand out?
- It’s low carb – Instead of using traditional corn tortillas or flour tortillas, which are higher in carbohydrates and can weigh you down, this breakfast casserole recipe uses low carb flour tortillas that are zero net carbs! This keeps protein the focus of the meal – which will help keep you going until your next meal.
- Vibrant seasoning – The cumin, chili powder and garlic powder are all that’s needed to add a spicy, bold flavor without salsa. Other recipes rely on salsa to give a Southwest flavor; however, this can make your casserole a soggy mess – especially the next day.
- Versatility – It’s easy to swap out proteins, vegetables and cheeses in this recipe. Try adding bacon, chorizo or ground turkey instead of sausage. Or swap/add different vegetables like mushrooms, zucchini, tomato or spinach.
- Make ahead – This make ahead marvel allows busy moms to prepare it in advance, saving precious time during hectic mornings. Just assemble the night before and bake in the morning. It’s the ideal breakfast dish for meal prep since you can easily reheat it in the morning without affecting the flavor or texture.

This was so, so good! I made it this afternoon and we had it for dinner! Was trying it out to see if I wanted to make it for guests and I do! Thanks for a fun and very tasty recipe!
Maze this several times now with different sausage meats, always delicious and super easy. The tortilla layers are not firm after baking, they’re definitely in the soggy zone no matter how I simmer down the meat mixture, bake and cool the dish , however not a deal breaker….I think I may try subbing fathead dough lasagne noodles for the tortillas to see if it improves the texture but I do recommend this recipe as is for the taste, versatility and ease of make-ahead meals. ♥️ Thank you for all your amazing recipes! 🙌🏻
