Mexican Breakfast Casserole Cooking Guide

Follow these simple steps to create your Mexican Breakfast Casserole:
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This will give your casserole the perfect baking environment.
Step 2: Cook the Chorizo and Vegetables
In a large skillet over medium heat, add the Mexican chorizo. Cook until browned and crumbly, about 5-7 minutes. Add the chopped onion and bell pepper to the skillet, and sauté until the vegetables are soft, approximately 3-4 minutes. Stir occasionally to ensure even cooking.
Step 3: Prepare the Tortilla Base
While the chorizo and vegetables are cooking, crush the corn tortilla chips slightly and spread them evenly on the bottom of your 9×13-inch baking dish. This will create a delicious base for your casserole.
Step 4: Mix the Eggs
In a mixing bowl, whisk together the eggs, milk, salt, and the can of Rotel (including the juice). This mixture will add moisture and flavor to your casserole.
Step 5: Assemble the Casserole
Layer the cooked chorizo and vegetable mixture evenly over the tortilla chips in the baking dish. Pour the egg mixture over the top, ensuring everything is well combined. Sprinkle the shredded Mexican blend cheese evenly over the top.
Step 6: Bake
Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the eggs are set and the cheese is bubbly and golden.
Step 7: Serve and Enjoy
Once baked, remove the casserole from the oven and let it cool for a few minutes. Cut into squares and serve warm. Enjoy your delicious Mexican Breakfast Casserole with additional salsa or avocado on the side for an extra touch!
