Southwest Breakfast Casserole
It’s hearty, packed with flavor, and a great way to feed a crowd.

A brunch breakfast bake is my favorite way to serve up a beautiful meal on a late weekend morning. This recipe is one that I come back to again and again, in different ways, but this particular variation might be my favorite. Spicy chorizo and a touch of chili powder is that spicy combo that goes so well with eggs. It all goes into one baking dish and comes out fluffy and flavorful. Let’s do brunch, southwestern style!

Chorizo is a spicy pork sausage, brick red in color from the red chiles that are mixed with the ground pork. It packs a spicy kick, which will be enhanced by the additions of chili powder and canned green chiles (you can choose what heat level you’d like here). This heat is balanced by eggs, milk, and plenty of cheese, and gets some additional texture and substance with the essential frozen breakfast blend of O’Brien potatoes.


A breakfast casserole like this comes together pretty quickly; the chorizo is cooked, the eggs are beaten and seasoned, and then it’s time to build the layers. First, the frozen potatoes, followed by chorizo, cheese, and then the egg mixture. A little more cheese goes on the top before the casserole goes into the oven for 40-45 minutes. The cheese on top will turn a beautiful golden brown, and the edges will get a little crispy. We all know it’s the crispy corners that everyone will fight over!

The casserole will need a few minutes to set before it’s sliced for serving; this essential pause allows the casserole to cool and the eggs to finish setting up. I like to scatter chopped cilantro over the top for a bit of freshness before serving (use parsley if you’re not a cilantro fan).

A Southwest Breakfast Casserole is a perfect way to serve up weekend brunch. It’s hearty, packed with flavor, and a great way to feed a crowd.
