Ingredients
Here’s what you’ll need to make this casserole:
- 6 whole poblano or Anaheim peppers (roasted, peeled, and seeded, or use canned for convenience)
- 2 cups shredded Monterey Jack cheese
- 2 cups shredded cheddar cheese
- 4 large eggs
- 1 cup milk
- 1/4 cup all-purpose flour
- 1/2 teaspoon baking powder
- 1/2 teaspoon garlic powder
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- Optional toppings: salsa, sour cream, chopped cilantro
Equipment
- 9×13-inch baking dish
- Mixing bowls
- Whisk
- Grater (if shredding cheese yourself)
Step-by-Step Instructions
Prepare the Peppers
- If using fresh peppers, roast them over an open flame or under the broiler until the skin is charred and blistered. Place in a sealed bag for 10 minutes, then peel off the skin. Remove seeds and stems.
- Skip this step if using canned peppers.
Assemble the Casserole
- Preheat your oven to 350°F (175°C).
- Lightly grease your 9×13-inch baking dish.
- Lay half of the roasted peppers in the bottom of the dish.
- Sprinkle half of the Monterey Jack and cheddar cheese over the peppers.
- Repeat with the remaining peppers and cheese to create layers.

Make the Egg Mixture
- In a mixing bowl, whisk together the eggs, milk, flour, baking powder, garlic powder, salt, and black pepper.
- Pour the mixture evenly over the peppers and cheese in the dish.
Bake
- Place the casserole in the oven and bake for 35–40 minutes, or until the top is golden brown and the egg mixture is set.
- Let it rest for 5 minutes before serving to make slicing easier.
Variations and Add-Ins
- Protein Boost: Add cooked ground beef, shredded chicken, or crumbled chorizo between the layers for a heartier dish.
- Vegetarian Twist: Toss in sautéed onions, corn, or black beans for extra flavor.
- Cheese Options: Experiment with pepper jack or queso fresco for a different twist.
Serving Suggestions
This casserole pairs beautifully with Spanish rice, refried beans, or a crisp side salad. For drinks, try a refreshing margarita or a cold Mexican beer. Top each slice with a dollop of sour cream, a drizzle of salsa, and a sprinkle of cilantro to bring the dish to life.
Tips and Tricks
- Prevent Sogginess: Make sure your peppers are well-drained if using canned, or pat them dry after roasting.
- Make Ahead: Assemble the casserole the night before and refrigerate. Bake it fresh the next day.
- Storage: Leftovers keep well in the fridge for up to 3 days. Reheat in the oven for the best texture.
