Ingredients

Scale

Chiles and Cheese

  • 14 ounces whole green chiles, canned (2 cans of 7 ounces each)
  • ¾ pound jack cheese, grated
  • 1 cup cheddar cheese, grated

Batter

  • 2 eggs
  • ½ cup all-purpose flour
  • 1½ cups milk
  • 1 teaspoon salt
  • ½ teaspoon black pepper

Instructions

  1. Prepare the baking dish and chiles: Spray a 9×9 inch baking dish with non-stick spray. Slice the whole canned green chiles wide open, rinse out any seeds, then drain thoroughly to remove excess moisture.
  2. Layer the chiles and cheese: Arrange half of the drained chiles in an even layer on the bottom of the baking dish. Sprinkle evenly with half of the grated jack and cheddar cheeses. Add the remaining chiles as a second layer, then top with the remaining cheeses to create a cheesy, layered casserole.
  3. Make the batter: In a small bowl, whisk together the eggs, all-purpose flour, milk, salt, and black pepper until fully blended and smooth. This mixture will hold the casserole together and create a creamy texture upon baking.
  4. Assemble and bake: Pour the batter evenly over the layered chiles and cheeses in the baking dish, ensuring full coverage. Bake uncovered at 350°F (175°C) for 30 to 35 minutes, or until the top turns golden brown and the casserole is set.
  5. Cool and serve: Remove the casserole from the oven and transfer it to a wire rack. Allow it to cool and firm up for a few minutes, which makes slicing easier. Slice into six equal pieces using a sharp knife, serve with a spatula, and enjoy this warm, cheesy chile dish.

Notes

  • For a spicier version, use green chiles with varying heat levels or add a pinch of cayenne pepper to the batter.
  • Make sure to drain the chiles well to prevent a watery casserole.
  • This casserole can be prepared ahead of time and baked when ready; just increase baking time slightly if baking from chilled.
  • Substitute milk with a lactose-free alternative to make it low lactose.
