Ingredients

• 6 pieces Poblano peppers (or canned whole green chilies, drained)
• 2 cups Monterey Jack cheese, shredded
• 1 cup Cheddar cheese, shredded
• 4 pieces Large eggs
• 1.5 cups Whole milk
• 1 tablespoon All-purpose flour
• 1 teaspoon Baking powder
• 0.5 teaspoon Salt
• 0.25 teaspoon Black pepper
• 0 as needed Cooking spray or oil

Directions

Step 1

Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish with cooking spray or oil.

Step 2

If using fresh poblano peppers, roast them over an open flame or under the broiler until the skins are charred and blistered. Transfer to a bowl, cover with a lid or plastic wrap, and let them steam for 10 minutes. Peel off the skins, remove the seeds, and slice each chili open to lie flat.

Step 3

If using canned chilies, simply drain and pat them dry with a paper towel.

Step 4

Layer half of the roasted (or canned) chilies in the bottom of the prepared baking dish.

Step 5

Sprinkle half of the shredded Monterey Jack and Cheddar cheeses over the chilies.

Step 6

Repeat with the remaining chilies and cheeses, creating a second layer.

Step 7

In a mixing bowl, whisk together the eggs, milk, flour, baking powder, salt, and black pepper until smooth and well combined.

Step 8

Pour the egg mixture evenly over the layered chilies and cheese in the baking dish.

Step 9

Bake in the preheated oven for 35-40 minutes, or until the casserole is golden brown on top and sets firmly in the center. To test doneness, insert a knife into the middle; it should come out clean.

Step 10

Allow the casserole to cool for 5-10 minutes before slicing and serving.
