What’s in chorizo breakfast casserole

Kicking off the day with spicy Southwest flavors means lots of veggies, chiles, and spice!

Here’s some of what we’ll add to the casserole:

  • Chorizo (My go-to brand is Mulay’s, but you can use whatever brand you like or make your own!)
  • Canned green chiles
  • Diced bell pepper
  • Frozen hashbrowns (this brand has no additives/fillers)

And to top it off?

  • Salsa (try to get a chunky, thick salsa — you don’t want anything too watery!)
  • Sliced avocado
  • Chopped fresh cilantro
  • Sliced fresh jalapenos

How long do breakfast casseroles keep in the fridge?

Breakfast casseroles make an amazing meal prep option — you’re cooking a whole tray of food that you can then reheat each morning.

If kept in a sealed container, this chorizo breakfast casserole should be good to go for up to a week in the fridge.

To reheat, just pop a single serving in the microwave for 1 1/2 minutes or put in an oven-safe dish and reheat in the oven.

With spicy chorizo, bell peppers, green chiles, and more, this Whole30 Southwest Chorizo Breakfast Casserole is anything but boring. Be sure to check the label of the frozen hashbrowns – many contain additives!

  1. Oil a 9”x13” rectangular baking dish.
  2. Heat olive oil in a cast iron skillet. Add chorizo and cook, breaking up with a spatula, for 5-8 minutes until almost cooked through.
  3. Place the hashbrowns in the baking dish. Add chorizo, green chiles, and bell peppers, stirring briefly.
  4. In a medium bowl, whisk eggs, coconut milk, scallions, and salt until blended. Pour over potato chorizo mixture.
  5. Unless preparing immediately, cover with a lid and refrigerate overnight.
  6. When ready to bake, remove from the refrigerator and let come to room temperature. Preheat the oven to 375 degrees F.
  7. Bake uncovered for 45 to 55 minutes or until knife inserted near the center comes out clean.
  8. Remove from the oven and top with jalapeno slices, avocado slices, cilantro, and salsa. Cut into 10 squares and serve.
