🌮 What Makes This Recipe So Special?

Traditional chile rellenos are delicious but time-consuming. This casserole version keeps the flavors you love — roasted green chiles and gooey cheese — and simplifies everything into a layered bake. The egg-and-milk mixture creates a soft, custardy texture that holds the casserole together while letting the chiles and cheese shine.

It’s hearty enough for dinner, yet light enough to serve at breakfast or brunch with fresh fruit and tortillas.

🔪 Step-by-Step Instructions

Step 1: Preheat and Prepare

Preheat your oven to 350°F (175°C).
Grease a 9×13-inch baking dish lightly with butter or nonstick spray.

Step 2: Layer the Chiles

Lay the drained green chile halves evenly across the bottom of the prepared dish.
Make sure they cover the surface for consistent flavor in every bite.

Step 3: Add the Cheese

Sprinkle the Monterey Jack cheese evenly over the chiles.
Follow with the cheddar cheese for a deeper, richer flavor.
