Why You’ll Love This Recipe
This Chile Relleno Casserole isn’t just mouth-wateringly good; it’s also incredibly easy to make. Unlike the traditional version that requires labor-intensive roasting and stuffing, this casserole simplifies the process without sacrificing flavor. The rich combination of cheeses perfectly complements the roasted chiles, while eggs provide a silky, comforting base. Best of all, it’s a one-pan meal, cutting down on prep and cleanup time.
Ingredients Notes
For the most authentic flavor, use fresh poblano chiles if possible. They add a subtle heat and smokiness to the dish. You can substitute canned green chiles for convenience. A blend of Monterey Jack and Cheddar cheese works well, but feel free to tweak the cheeses to suit your taste. When selecting eggs, farm-fresh ones will offer a richer texture and color.
Recipe Steps
Step 1
Preheat your oven to 350°F (175°C). Prepare the baking dish by lightly greasing it with cooking spray to prevent sticking and ensure an easy cleanup.
Step 2
Lay the roasted or canned chiles flat in the bottom of the dish. This forms the flavorful base for your casserole, creating an even layer is key.
Step 3
Mix together evenly grated cheese and sprinkle half over the chile layer. The cheeses chosen should ideally balance each other in terms of sharpness and meltability.

Step 4
In a separate bowl, whisk the eggs until well blended and add a pinch of salt and pepper. Pour this mixture over the layers of chiles and cheese.
Step 5
Top with the remaining cheese, then bake in the oven for 25-30 minutes, or until the eggs are fully set and the top is golden brown. Let it rest for about 5 minutes before serving.
Storage Options
Store any leftover casserole in an airtight container in the refrigerator for up to 3 days. For longer storage, slice the casserole into portions, wrap tightly in plastic wrap, then foil, and freeze for up to 3 months. Reheat in a microwave or bake in a preheated oven at 350°F until warmed through.
Variations & Substitutions
For a vegetarian twist, consider adding sautéed mushrooms, spinach, or corn kernels. If you prefer a milder dish, substitute the poblano chiles with bell peppers. To make it gluten-free, ensure all packaged ingredients are certified gluten-free.
Serving Suggestions
This casserole pairs excellently with a fresh green salad or a side of refried beans for a hearty meal. Consider serving it at brunches, family dinners, or festive gatherings. A dollop of sour cream or a sprinkle of fresh cilantro adds a fresh finish to each serving.
