Instructions to Prepare Tex-Mex Breakfast Casserole

Step 1: Preheat the oven

Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish with non-stick spray or butter.

Step 2: Cook the chorizo

In a large skillet over medium heat, cook the chorizo until browned. Drain excess grease and set aside.

In the same skillet, add the onion and bell peppers. Cook for 4–5 minutes until softened. Add hash browns and stir to combine.

Step 4: Whisk eggs and seasonings

In a large bowl, whisk together eggs, milk, salt, pepper, chili powder, and cumin until well blended.

Step 5: Assemble the casserole

Spread the chorizo and vegetable mixture evenly in the baking dish. Scatter black beans on top. Pour the egg mixture over everything, then sprinkle the cheddar and pepper jack cheese evenly across the top.

Step 6: Bake until set

Bake for 35–40 minutes or until the center is set and the top is golden and slightly crispy.

Step 7: Cool and serve

Allow the casserole to rest for 5–10 minutes before slicing. Serve warm with salsa and avocado.
