What is in a Mexican Breakfast Casserole?
The amazing part of this recipe is how versatile it is. Of course, the fact that it is a great make-ahead recipe is also a bonus! It is a Mexican casserole that meets an egg bake. So wholesome and delicious! Let’s gather the ingredients needed:
- Onions: Chose a yellow onion, they are best to sauté and some green ones too to mix with the tomato
- Garlic: Fresh garlic is best, but if you are in a pinch, use garlic salt or granulated garlic if you wish
- Pepper: I prefer yellow, orange, or red for their sweetness
- Ground sausage: You can also use breakfast sausage; any meat would work really
- Seasoning: Use what you have on hand; we always have Tex-Mex or salt-free taco seasoning, which works great for this recipe
- Corn: can be canned or frozen
- Black beans: they can be canned or cooked, and you can use a bean medley too
- Tomato: I used a fresh juicy tomato; however, you can also use a salsa mix from a jar
- Tortilla: You can use the flour tortillas, whole wheat, or gluten-free ones
- Cheese: Use your favorite one, preferably one that melts well, such as mozzarella or cheddar
- Eggs: Select a dozen medium or large eggs
- Milk: I used 2%, but any would work; however, the richer, the creamier. And heavy cream or half and half would be a good option too.
- Topping: Cube an avocado and tomato, and chop some coriander. Combine all in a bowl and season with lime juice and salt. Serve on top of your breakfast casserole.
TIP: If you can not find ground sausage meat, just buy sausages and take the meat out of it!
How to Make a Mexican Breakfast Casserole
Before getting started, pre-heat your oven to 400F and grab your baking dish.
First, you will need to prepare the meat mixture. In a large skillet, sauté the garlic, onion, and pepper. Once tender, after 4-5 minutes, add in the sausage meat and cook until it is no longer red and break the meat into small pieces. Add the taco seasoning, stir well and set aside.
Next, in a bowl, mix the corn, black beans, diced tomato, and green onion.
Then, in a mixing bowl, crack all your eggs and whisk them with some milk. Set aside also.
Lastly, cut your tortillas into quarters. Lay them at the bottom of a lightly greased dish.
Now we have all the elements to assemble the casserole, and it will be ready to be popped in the oven! Grab your shredded cheese as well!
TIP: Use some cooking spray to grease the bottom of your dish!
ASSEMBLING:
On the tortilla, spread a third of the sausage mixture, then a third of the corn/bean mixture, and then sprinkle with cheese of your choice. Pour about a third of the egg mixture.
TIP: Shake your dish so the eggs spread evenly.
Repeat 2 more times or until you do not have any more ingredients. Top the casserole with extra cheese, as you can never have too much cheese, right? Lastly, cover with aluminum foil.
Bake in the oven, covered for 40 minutes and another 15 minutes uncovered.
Variations and Suggestions
When we are cooking at home, we all love having a little bit of liberty in a recipe and being able to swap a few ingredients, so it is perfect to our taste. Here, there are a few things you can adapt to your liking or dietary restrictions.
Vegetarian: Use plant-based meat in lieu of sausage or just omit and add a bit more vegetables.
Gluten-free: switch up for some corn tortillas or gluten-free ones!
Spice it up: Add that spicy sausage meat to the dish or maybe some chorizo. Or season with some chili powder to add a little kick to your brunch!
IDEAS: Layer some sliced potatoes or some hash or hashbrowns to replace the tortillas. There are also versions where you use tortilla chips! They would be wonderful as a topping afterwards.
