How to Make Chile Relleno Casserole

Step 1: Prepare the Peppers

Roast the poblano peppers by placing them under a broiler or over an open flame until the skins are blackened. Let them cool, then peel away the charred skin, remove seeds, and roughly chop into bite-sized pieces.

Step 2: Sauté Aromatics

In a skillet, heat a bit of oil and sauté diced onion and minced garlic until fragrant and translucent, about 3 to 5 minutes. This creates a flavorful base for the casserole.

Step 3: Mix the Egg and Cheese Layer

In a large mixing bowl, whisk together eggs, sour cream, and half of the shredded cheeses. Add spices and salt, then gently stir in the chopped roasted peppers and sautéed aromatics.

Step 4: Assemble the Casserole

Pour a thin layer of tomato or enchilada sauce onto the bottom of a greased baking dish. Layer half of your egg and pepper mixture on top, then sprinkle remaining cheese over it. Add the rest of the egg and pepper mixture as the final layer and top with remaining sauce and cheese.

Step 5: Bake to Perfection

Bake in a preheated oven at 350°F (175°C) for 35 to 40 minutes until the casserole is set, golden, and bubbly on top. Allow to cool slightly before serving.

Pro Tips for Making Chile Relleno Casserole

• Use Fresh Poblano Peppers: Fresh roasted poblanos taste better than jarred and give your casserole authenticity.
• Don’t Skip the Roasting: Roasting adds smoky flavor and softens the peppers perfectly.
• Let It Rest: Let the casserole stand for 10 minutes after baking to help it set fully and make slicing easier.
• Cheese Choice Matters: Combining stretchy and sharp cheeses creates wonderful texture and flavor depth.
• Adjust Spices to Taste: Start with small amounts, then add more chili or cumin depending on your heat preference.

How to Serve Chile Relleno Casserole

Garnishes

Top with fresh cilantro leaves, sliced green onions, or a dollop of sour cream to enhance flavor and add inviting color that brightens each bite.

Side Dishes

Serve alongside Mexican rice, refried beans, or a crisp mixed green salad to complement the richness and provide a balanced meal.

Creative Ways to Present

Cut the casserole into individual squares and serve with warm corn tortillas for taco-style servings or plate with a squeeze of fresh lime and avocado slices for a restaurant-worthy touch.

Make Ahead and Storage

Storing Leftovers

Keep leftovers in an airtight container in the refrigerator for up to 3 days. The flavors meld beautifully, making the next-day meal just as delicious.

This casserole freezes well. Cool completely, then wrap tightly with foil or plastic wrap and freeze in portions for up to 2 months. Thaw overnight in the fridge before reheating.

Reheating

Warm leftovers in the oven at 325°F (165°C) for about 15 minutes to maintain the original texture and flavor, or microwave for quick reheats but beware of drying out the edges.
