Step 1

Preheat the oven to 375°F.

Step 2

Open the can of chilies, split them lengthwise, and lay half of them in a 9x13-inch baking dish. There's no need to wash or deseed the chilies. Sprinkle half of the mixed cheeses over the chilies.

Step 3

Arrange the remaining chilies on top and cover with the rest of the cheese.

Step 4

In a blender, combine the milk, eggs, flour, salt, paprika, and pepper. Blend until smooth.

Step 5

Pour this mixture evenly over the chilies and cheese in the baking dish.

Step 6

Bake for 40-50 minutes, or until the casserole is set and golden brown on top.

Step 7

Remove from the oven, let cool slightly, and slice to serve.
