Step‑by‑Step Instructions for Mexican Breakfast Casserole
Step 1: Preheat and Prepare the Baking Dish
Begin by preheating your oven to 375°F (190°C). While the oven heats up, lightly grease a 9×13-inch baking dish with cooking spray or olive oil to prevent sticking. The greased surface will ensure that your Mexican Breakfast Casserole releases easily after baking, giving you perfect slices to serve.
Step 2: Sauté the Meat and Vegetables
In a large skillet, cook the chorizo or breakfast sausage over medium heat for about 8-10 minutes, adding the diced onion and red bell pepper halfway through. Stir occasionally until the meat is browned and veggies are tender. Drain any excess grease, and set the mixture aside. The savory aroma will fill your kitchen, setting the stage for this flavorful casserole.
Step 3: Whisk the Egg Mixture
In a mixing bowl, whisk together 8 large eggs, 1 cup of milk (or a non-dairy alternative for vegan options), and spices like cumin and paprika. Make sure to blend well until the mixture is smooth and frothy. This egg mixture will be the binding agent for the Mexican Breakfast Casserole, and you can adjust the seasoning to suit your taste.
Step 4: Layer the Tortillas
Start assembling your casserole by placing half of the corn tortillas in a single layer at the bottom of the greased baking dish. Ensure they cover the entire surface; this will act as the foundation that holds all the delicious layers together. You can overlap them slightly if necessary for a complete base.
Step 5: Add the First Layer of Fillings
Next, spoon half of the cooked meat and veggie mixture evenly over the tortilla layer. After that, sprinkle half of the shredded cheddar and pepper jack cheeses on top. This creates a rich, flavorful layer that complements the tortillas beautifully, enhancing the overall texture and taste of your Mexican Breakfast Casserole.
Step 6: Repeat the Layering Process
Continue the layering process by adding the remaining corn tortillas over the cheese. Follow up with the rest of the meat and veggie mixture, then pour half of the egg mixture over all the layers. Finally, top this with the remaining cheeses. This ensures that every bite of your casserole is packed with flavor and richness.
Step 7: Bake the Casserole
Cover the casserole with aluminum foil to prevent over-browning and bake in the preheated oven for 30 minutes. Afterward, remove the foil and bake for an additional 10-15 minutes, or until the top is golden and bubbly. You’ll know it’s ready when the cheese is melted and the edges are slightly crispy.
Step 8: Rest and Serve
Allow the Mexican Breakfast Casserole to rest for about 10 minutes before slicing. This resting period will help it set, ensuring easier serving. Just before serving, feel free to garnish with fresh cilantro, diced avocado, or salsa for a fiesta touch! Enjoy the heartfelt flavors and great company that this dish brings to your table.

Mexican Breakfast Casserole Recipe FAQs
How do I select the best tomatoes for my Mexican Breakfast Casserole?
Absolutely! When choosing tomatoes, look for ones that are firm, with vibrant color and smooth skin. Avoid any with dark spots or wrinkles, as they may be overripe. For this dish, ripe Roma or vine-ripened tomatoes work wonderfully, adding juiciness and flavor!
How should I store leftovers of the Mexican Breakfast Casserole?
You can store leftover casserole in an airtight container in the refrigerator for up to 3 days. Just make sure to let it cool completely before sealing it up to prevent condensation. This ensures it stays fresh and delicious for your next meal!
Can I freeze my Mexican Breakfast Casserole?
Yes, you can freeze it for up to 2 months! To do this, wrap it tightly in aluminum foil or plastic wrap after it has cooled completely. For reheating, thaw it in the fridge overnight, then heat in the oven at 350°F (175°C) for 15-20 minutes until warmed through.
What do I do if my casserole ends up too watery?
If you find your Mexican Breakfast Casserole is watery, try this for the next time: Ensure that your vegetables, particularly tomatoes or bell peppers, are sautéed enough to release most of their moisture before layering them into the dish. Additionally, you can reduce the amount of milk or egg slightly and consider adding more tortillas to help absorb excess moisture.
Are there any dietary considerations I should be aware of?
When adjusting for dietary needs, just remember to substitute ingredients mindfully! For gluten-free options, swap corn tortillas with gluten-free ones or sweet potatoes. If you’d like it vegan, use plant-based sausages, non-dairy milk, and vegan cheese. Always check labels if there are specific allergens, especially with processed ingredients!
How do I prevent the tortillas from becoming soggy in my casserole?
Very good question! To keep the tortillas from becoming soggy, you can lightly toast them in a dry skillet for a minute on each side before layering. This pre-cooking method helps to create a barrier, keeping them firm and tasty when baked in the casserole!
