Ingredients

• 6 Poblano peppers
• 6 Eggs
• 1.5 cups Whole milk
• 0.5 cups All-purpose flour
• 1 teaspoon Baking powder
• 1 teaspoon Salt
• 0.5 teaspoon Pepper
• 2 cups Shredded Monterey Jack cheese
• 1 cup Shredded cheddar cheese
• 1 4-ounce can Canned diced green chiles (optional)
• 1 as needed Cooking spray or oil

Directions

Step 1

Preheat oven to 350°F (175°C). Lightly grease a 9x13-inch baking dish with cooking spray or oil and set aside.

Step 2

Roast the poblano peppers over an open flame or under a broiler until the skins are charred and blistered. Place the charred peppers in a bowl, cover with plastic wrap, and let them steam for 10 minutes.

Step 3

Once cooled, peel off the skins of the peppers. Remove the stems and seeds, then lay the peppers flat and set them aside.

Step 4

In a large mixing bowl, whisk together the eggs, whole milk, flour, baking powder, salt, and pepper until smooth. This will form the custard mixture for the casserole.

Step 5

Layer half of the roasted poblano peppers in the bottom of the prepared baking dish. Top with 1 cup of shredded Monterey Jack cheese and 1/2 cup of shredded cheddar cheese. If using canned diced green chiles, sprinkle them over this layer as well.

Step 6

Repeat the layering process with the remaining poblano peppers, another 1 cup of Monterey Jack cheese, and 1/2 cup of cheddar cheese.

Step 7

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

Step 8

Place the casserole in the preheated oven and bake for 35-40 minutes, or until the eggs are set and the top is golden and bubbly.

Step 9

Remove the casserole from the oven and let it cool for 5-10 minutes before slicing and serving.

Step 10

Serve warm, optionally garnished with fresh cilantro, sour cream, or a drizzle of hot sauce for added flavor.
