Ingredients
- 14 ounces whole green chiles, canned (2 – 7 ounce cans)

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

- Step 2: Arrange half of the drained chiles in an even layer at the bottom of the prepared baking dish.
- Step 3: Sprinkle half of the combined grated jack and cheddar cheeses evenly over the first chile layer.
- Step 4: Add the remaining chiles in a second layer on top of the cheese, then sprinkle with the remaining grated jack and cheddar cheeses.
- Step 5: In a small bowl, whisk together the eggs, flour, milk, salt, and black pepper until the mixture is smooth and fully blended.
- Step 6: Pour the egg mixture evenly over the layered chiles and cheeses in the baking dish.
- Step 7: Place the casserole in the oven and bake uncovered for 30 to 35 minutes, or until the top is golden brown and the casserole is set.
- Step 8: Remove the casserole from the oven and let it cool on a wire rack for a few minutes to firm up. Slice into 6 equal pieces and serve warm.
Tips & Variations
- For extra flavor, add diced onions or a pinch of cumin to the egg mixture before baking.
- Use a blend of pepper jack cheese for a spicier twist.
- Serve with a side of salsa or guacamole for added zest.
- If fresh green chiles are available, roasting and peeling them adds a smoky depth to the casserole.
Storage

FAQs
Can I use fresh green chiles instead of canned?
Yes, fresh roasted and peeled green chiles can be used. They add a smoky flavor but may require roasting and peeling beforehand, which adds extra preparation time.
Is it possible to freeze the casserole?
While freezing is possible, the texture of the cheese and chiles may change slightly. If freezing, wrap tightly and thaw in the refrigerator before reheating in the oven for best results.

Ingredients
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
- 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.
- 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.
- 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.
- 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.
- 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.
