Step‑by‑Step Instructions for Hearty Mexican Breakfast Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven warms up, grab a 9×13-inch baking dish and lightly grease it with cooking spray or olive oil to ensure your Mexican Breakfast Casserole won’t stick.
Step 2: Cook the Meat and Vegetables
In a large skillet over medium heat, add your chorizo or breakfast sausage. Sauté until browned, about 5-7 minutes, then mix in chopped onion and diced red bell pepper. Cook until the veggies are softened, about 3-4 minutes, and carefully drain any excess grease before setting the mixture aside.
Step 3: Prepare the Egg Mixture
In a large mixing bowl, whisk together a dozen eggs, a cup of milk, cumin, paprika, and a pinch of salt until well-blended and fluffy. The mixture should appear creamy and smooth. This egg mixture will bind your Mexican Breakfast Casserole, adding richness and flavor to every layer.
Step 4: Build the Casserole Layers
Layer half of the corn tortillas across the bottom of the greased baking dish, ensuring they cover the bottom evenly. Next, spread half of the sausage and veggie mixture over the tortillas, followed by half of the shredded cheddar and pepper jack cheeses. Then, pour half of the egg mixture over this first layer, allowing it to sink in slightly.
Step 5: Complete the Layering
Repeat the layering process starting with the remaining tortillas. Add the rest of the meat mixture, followed by the remaining cheeses, and finally, pour the rest of the egg mixture evenly over the top. Ensure that everything is well-distributed for a perfectly cooked Mexican Breakfast Casserole.
Step 6: Bake the Casserole
Cover the baking dish tightly with aluminum foil, which will help steam the casserole as it cooks. Place it in the preheated oven and bake for 30 minutes. After that, remove the foil and bake for an additional 10-15 minutes or until the top is golden brown and the egg is set.
Step 7: Rest and Serve
Once baked, let the Hearty Mexican Breakfast Casserole rest for about 10 minutes. This resting period allows the casserole to set and makes slicing easier. Serve warm, garnished with fresh cilantro, avocado slices, or your favorite salsa for a delicious start to your day!

Mexican Breakfast Casserole Recipe FAQs
How do I choose the best chorizo or sausage for my casserole?
Absolutely! Look for chorizo that’s fresh, not too greasy, and has a vibrant red color indicating quality spices. If using breakfast sausage, opt for a savory blend without excessive fillers. For those seeking vegetarian options, black beans make an excellent substitute, offering a hearty texture and protein.
What’s the best way to store my leftover Mexican Breakfast Casserole?
You can store leftovers in an airtight container in the fridge for up to 3 days. To reheat, pop it in the microwave for a quick meal, or warm it up in the oven at 350°F (175°C) until heated through for the best results.
Can I freeze the Mexican Breakfast Casserole? How should I do it?
Certainly! To freeze, first, let the casserole cool completely. Then, slice it into portions, wrap each slice in plastic wrap, and place wrapped portions in a freezer-safe bag. This way, it can stay fresh for up to 3 months. When ready to enjoy, thaw overnight in the fridge and bake at 350°F (175°C) until warm.
What can I do if my casserole turns out soggy?
If that happens, don’t fret! To avoid sogginess next time, make sure to lightly toast the corn tortillas before layering them in the casserole. You can also try reducing the liquid from the egg mixture slightly or compressing each layer during assembly to help the egg absorb evenly. Additionally, letting the casserole rest before slicing helps firm it up.
Are there any dietary considerations I should keep in mind?
Very much so! This Mexican Breakfast Casserole can be easily adapted for various dietary needs. For a gluten-free version, ensure your tortillas are gluten-free. If concerned about allergies, double-check the ingredients in your sausage and cheeses. For dairy-free options, substituting plant-based milk and cheese works wonderfully without sacrificing flavor. Always consider your guests’ dietary restrictions and customize accordingly!
How can I enhance the flavor of my casserole?
To amp up the flavors, try layering additional spices like smoked paprika or chili powder. Adding fresh ingredients, such as chopped cilantro and diced jalapeños before serving, can brighten up the dish. You might even want to incorporate fresh diced tomatoes or avocado on top for a refreshing twist.
