Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish.

Layer the chiles at the bottom of the dish. Make sure they’re spread out evenly.

Top with cheese. Sprinkle the shredded cheddar and Monterey Jack cheeses over the chiles. You can never have too much cheese, right? 😋

Whisk together the eggs, evaporated milk, flour, baking powder, salt, and pepper in a bowl until smooth and well combined.

Pour the egg mixture over the chiles and cheese, making sure it spreads evenly across the dish.

Bake in the preheated oven for 35-40 minutes, or until the casserole is set and golden brown on top.

Let it cool for a few minutes before slicing, and then serve with salsa or hot sauce if you want an extra kick! 🌶️
