Notes
Tips for the Best Chile Relleno Casserole
Roasting the poblanos properly is key. You want that charred skin because it adds a smoky depth that defines the dish. Don’t skip the steaming step—it makes peeling the skins much easier.
Also, be careful not to overbake the casserole. You want the center to be just set but still soft and custardy.
Variations to Try
Meaty Version
Add cooked ground beef, chorizo, or shredded chicken between the layers for a heartier dish.
Vegetarian Delight
Include sautéed onions, mushrooms, or zucchini for extra flavor and texture.
Spicy Kick
Add sliced jalapeños or a dash of hot sauce to bring more heat.
Extra Cheesy
Mix different cheeses like mozzarella, pepper jack, or queso fresco for a richer flavor.
