• ½ cup white onion, finely diced
• 1 (4-ounce) can diced green chiles, drained
• 10 large eggs
• ½ cup milk (whole milk or any milk of choice)
• 1½ cups shredded cheddar cheese (or a blend like cheddar-jack)
• 1 tablespoon olive oil
• Salt and pepper, to taste
• ½ teaspoon paprika (optional, for extra color and flavor)

Step-by-Step Instructions

Follow these detailed steps to make sure your casserole comes out just right every time.

1. Preheat and Prepare Your Baking Dish

• Preheat your oven to 375°F (190°C).
• Lightly grease a 9×13-inch baking dish with nonstick spray or a thin coating of olive oil.

2. Cook the Ground Chicken

• Heat 1 tablespoon of olive oil in a large skillet over medium heat.
• Add the ground chicken and break it up using a spatula.
• Cook until fully browned and cooked through, about 5–7 minutes.
• Season with salt, pepper, garlic powder, cumin, and paprika.
• Once cooked, set aside to cool slightly.

3. Sauté the Vegetables

• In the same skillet (no need to wash), add a touch more oil if needed.
• Sauté the onion, red bell pepper, and poblano pepper for about 4–5 minutes, or until slightly softened.
• Stir in the green chiles and cook for another 1–2 minutes.
• Remove from heat.

4. Assemble the Casserole Base

• Spread the frozen potatoes evenly in the bottom of the greased baking dish.
• Layer the cooked vegetables and then the seasoned ground chicken on top.
• Sprinkle half of the cheese over the mixture.

5. Whisk the Eggs

• In a large mixing bowl, whisk together the eggs and milk until well blended.
• Add a pinch of salt and pepper to the egg mixture.
• Slowly pour the eggs evenly over the entire dish.

6. Top and Bake

• Sprinkle the remaining cheese over the top of the casserole.
• Cover with foil and bake for 35–40 minutes, until the eggs are just set.
• Remove foil and bake for an additional 10 minutes, or until the top is lightly golden and bubbling.

7. Cool and Serve

• Allow the casserole to cool for 5–10 minutes before slicing. This helps it set up and makes serving easier.
• Slice into squares and garnish with cilantro, avocado, or a drizzle of your favorite hot sauce.

Beginner Tips and Notes

Whether you’re new to baking casseroles or just want to get the most flavor possible, these tips will help:

• Don’t skip seasoning the meat. Since you’re replacing chorizo, adding spices like cumin, paprika, and garlic powder brings the savory flavor it’s known for.
• You can use fresh potatoes instead of frozen. If using fresh, dice them small and cook briefly in a skillet first to soften them before layering.
• Make it dairy-free by using a plant-based milk and dairy-free cheese.
• Let it cool before slicing to prevent a runny casserole.
• Add greens. Want to boost nutrition? Fold in chopped spinach or kale with the vegetables.
• Make ahead. This dish can be made the night before, stored in the fridge, and baked the next morning.
