The refrigerated shredded potatoes tend to work better than the frozen kind. However, you can use the frozen ones just thaw them before adding to the casserole. You could also shred your own potatoes if you prefer!

I use whole milk for the creamiest results, but you could skim milk if you prefer.

While the flavors and red and green bell peppers blend best in this recipe, you can also use yellow or orange peppers.

Add some extra kick to this Mexican chorizo breakfast casserole by dicing up a poblano peppers, shishito peppers, or jalapeños.

Use whatever type of cheese you want. Shredded cheddar, Monterey jack, Colby jack, Mexican blend, or any other type of shredded cheese you prefer.

While this is a Mexican casserole bake and uses chorizo, you can use spicy breakfast sausage if you are unable to locate chorizo. You could even repurpose some leftover Mexican style meat like from these quesabirria tacos.

How to Make Mexican Breakfast Casserole

Follow these instructions to easily make the best Mexican breakfast casserole:

Preheat your oven to 375°F (190°C) and then spray a 9x13 inch baking dish with non stick cooking spray and set it aside.

In a large skillet, cook the chorizo and then drain excess grease off and set it aside. Use a sharp knife and cutting board and dice the bell peppers, then set them aside.

In a medium mixing bowl, whisk together the eggs and milk until thoroughly combined. Then pour the egg mixture into the previously prepared casserole dish.

Then add chorizo, peppers, shredded potatoes and ½ cup of cheese to the eggs and use a spoon to gently mix together.

Top the casserole with extra shredded cheese, then bake for 30 minutes.

Once the cheese is melted and the eggs are set, the casserole should be golden brown and ready to eat!

Slice into even squares and serve.

Serve a peanut butter banana smoothie or coffee smoothie with your casserole for a touch of something sweet. Or you could make a batch of healthy banana chocolate chip muffins or air fryer glazed donuts with breakfast too!

This goes great with some other breakfast favorites like blueberry stuffed french toast and malted waffles.

Tips for Success

Mexican chorizo breakfast casserole is just the best thing to eat in the mornings. Here's a few tips to help you out:

• For the most gooey and cheesy casserole, shred your own cheese. Store-bought shredded cheese has ingredients in it that make it not melt as well as freshly shredded cheese.
• Whisk the eggs well and make sure the yolks are thoroughly combined with the whites before mixing with the other casserole ingredients.
• Look for the edges of the casserole to slightly pull away from the casserole dish. This helps to determine if the casserole is fully cooked and if the eggs are set!
