Mexican Egg Casserole – Tip and Tricks
- Wear gloves! These protect your hands from the irritating oils found in jalapeño peppers and reduce the chance of transferring them to your eyes or other sensitive areas.
- Add a topping. Along with extra salsa and bacon, try sprinkling chopped avocado or cilantro over your plate. Even a dollop of sour cream would be delicious!
- Tip for making bacon: Easily cook an entire package at once by using your oven. You’ll avoid splatters, and you can prep the other ingredients while it bakes.
- Want to make it ahead of time? Assemble everything as directed, then cover and refrigerate the Mexican egg bake overnight.
Allow the casserole to sit on the counter for about 30 minutes before baking, so it cooks evenly.
Tortilla Breakfast Casserole Variations
What’s great about this Mexican egg casserole recipe is that it’s so versatile! You can add or substitute all kinds of ingredients, so it tastes just how you like it.
- Add beans. Include black beans in one of the layers for extra protein, or try corn and bell peppers for an extra serving of veggies.
- Swap the meat. You could even replace some or all of the bacon with ground pork, chicken, or turkey sausage.
- Go vegetarian! For a vegetarian option, substitute plant-based bacon, vegan crumbles, or sauteed mushroom instead.
Kitchen Tools You Will Need
- 9×13 Baking Dish – This set is one of my favorites! It comes with a lid for easy storage and is great for casseroles too.
- Mixing Bowls – I like to have a variety of sizes on hand, and this set has them all.
- Box Grater – As much as I love buying bagged shreds because it’s easier, freshly grated cheese melts down so much smoother and tastes better too.
Mexican Egg Bake FAQs
Either will work fine in this breakfast taco casserole recipe, though flour tortillas will be softer and may not hold their shape as well.
Once cooked, this Mexican egg bake should keep for up to 5 days in the refrigerator. Store it tightly covered, or transfer any remaining slices to an airtight container to keep them fresh.
You sure can! Allow it to cool, then cover the dish with a layer of plastic wrap and foil. Store in the freezer for up to 2 months.
Thaw the Mexican breakfast casserole overnight in the refrigerator and bake at 350°F for 20 to 25 minutes, or until warmed through.

That looks really good. Might have to try that some weekend.
This was delicious! I was wondering if you have ever tried it with flour tortillas and if you have ever assembled it the night before and baked it in the morning?
The recipe says it can be made the night before. There's no reason you couldn't use flour tortillas though they will probably be very soft like when you make mexican chicken casserole.
Do the tortillas get soggy?
When making rhe night before, do you partially bake it before refrigeration? Or just mix and layer? If you just mix and layer, won't the eggs seep under the tortillas? Siunds wonderful, anxious to try it!
I liked this recipe. I did how ever add diced hash browns for more of a filler. It was GREAT.
I love love love Mexican dishes, and never thought of a breakfast casserole. This is going to be made for family and friends for years to come! It tasted amazing.
I can’t get the video. Looks delicious. Having people for bunch the 25th of October
If you scroll to the bottom you will see the video under the recipe, hope this helps!
TSRI Team Member,
If I want to half the recipe, should I use a smaller dish than the 9×13?
