Ingredients

6 large roasted green chiles, peeled and seeded
2 cups shredded Monterey Jack cheese
1 cup shredded sharp cheddar cheese
5 large eggs
1/2 cup whole milk
2 tablespoons all-purpose flour
1 teaspoon baking powder
1/2 teaspoon salt
1/4 teaspoon black pepper
Cooking spray or butter, for greasing the dish

Instructions

Step 1: Preheat your oven to 375°F (190°C). Lightly grease your baking dish with butter or cooking spray.
Step 2: In a bowl, whisk together the eggs, milk, flour, baking powder, salt, and pepper until smooth.
Step 3: Spread half of the roasted green chiles evenly across the bottom of the prepared baking dish.
Step 4: Sprinkle half of the shredded Monterey Jack and cheddar cheeses over the chiles.
Step 5: Layer the remaining chiles on top of the cheese, then cover with the rest of the shredded cheeses.
Step 6: Pour the egg mixture evenly over the layered chiles and cheese.
Step 7: Bake uncovered for 30–35 minutes, or until the top is golden and the center is set.
Step 8: Allow the casserole to rest for at least 10 minutes before slicing to help it firm up for easier serving.
Step 9: Serve warm, optionally topped with fresh cilantro, avocado slices, or a drizzle of sour cream for extra flavor.

Tips & Variations

For extra smoky flavor, use fire-roasted canned green chiles if fresh ones are unavailable.
Mix in cooked, crumbled chorizo or ground beef for a heartier version.
Swap Monterey Jack for pepper jack cheese to add a spicy kick.
Ensure the eggs are well whisked for a smooth and fluffy texture in the casserole.
Letting the casserole rest before serving helps it set fully and makes slicing neater.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual portions gently in the microwave until warmed through, or warm the entire casserole covered with foil in a 350°F (175°C) oven for about 15 minutes.

FAQs

Can I use canned green chiles instead of fresh?

Yes, fire-roasted canned green chiles make a convenient substitute and maintain a smoky flavor similar to fresh roasted chiles.

How can I make this dish ahead of time?

You can assemble the casserole the night before, cover it tightly, and refrigerate. Bake it fresh the next day, adding a few extra minutes to the baking time if baking from cold.
