Tips & Variations
- For added flavor, try adding diced onions or jalapeños along with the peppers.
- Use turkey chorizo for a leaner option without sacrificing taste.
- If you prefer a creamier texture, substitute half-and-half for the milk.
- Leftover casserole can be topped with fresh salsa or avocado slices for extra freshness.
Storage
Store leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat individual servings in the microwave for 1-2 minutes until warmed through, or reheat the entire casserole in a 350°F oven for about 15 minutes.

FAQs
Can I use frozen potatoes instead of refrigerated?
It’s best to use refrigerated shredded potatoes to avoid excess water, which can make the casserole soggy. If using frozen, thaw and drain well before adding.
Can I make this casserole ahead of time?
Yes! You can assemble the casserole the night before, cover it, and refrigerate. Bake fresh in the morning, adding 5–10 extra minutes to the baking time if it’s cold from the fridge.

Instructions
- Prepare the Pan: Preheat your oven to 375°F (190°C). Spray a 9×13-inch baking dish with cooking spray to prevent sticking and set it aside.
- Cook the Chorizo: In a skillet over medium heat, cook the fresh chorizo until it is fully browned and cooked through, breaking it apart as it cooks. Drain any excess grease to avoid a greasy casserole.
- Prep the Bell Peppers: Dice the red and green bell peppers into small, even cubes to ensure even distribution and texture throughout the casserole.
- Assemble the Casserole: In the prepared baking dish, layer the cooked chorizo evenly, followed by the diced bell peppers, shredded potatoes, and then sprinkle with ½ cup of shredded cheddar cheese.
- Make the Egg Mixture: In a bowl, whisk together the 12 large eggs and ½ cup of milk until fully blended. Pour this mixture evenly over the layered ingredients in the pan. Gently mix the ingredients together in the pan to combine. Finally, sprinkle the remaining ¼ cup of shredded cheddar cheese on top.
- Bake to Perfection: Place the casserole in the preheated oven and bake for 30 minutes, or until the eggs are fully set and the cheese is melted and slightly golden. Once out of the oven, let the casserole rest for 5 minutes before slicing and serving.
Notes
- Use refrigerated shredded potatoes rather than frozen for best texture.
- Be sure to drain excess grease from the chorizo to keep the casserole from becoming too oily.
- The casserole can be prepared the night before and baked fresh in the morning.
- Feel free to customize with additional vegetables like onions or jalapeños for extra flavor.
- This recipe serves 8 but can be halved or doubled as needed.
