How to Make Easy Chile Relleno Casserole
-
Roast Peppers: Preheat your oven to broil and place the poblano peppers on a baking sheet. Roast them until the skin is blackened, about 6-8 minutes, then transfer to a zip-lock bag to steam.
-
Prep Peppers: After about 10 minutes, carefully remove the cooked peppers from the bag. Peel off the charred skin, discard the seeds and stems, and set the roasted peppers aside.
-
Preheat Oven: Set your oven to 350°F (175°C) and lightly spray an 8-inch baking dish with cooking spray to prevent sticking.
-
Make Batter: In a mixing bowl, whisk egg whites until stiff peaks form. Gently fold in the egg yolks along with all-purpose flour, milk, baking powder, sea salt, and black pepper until well combined.
-
Assemble Casserole: Pour half of the batter into the prepared dish. Layer with half of the roasted poblano peppers and half of the Monterey Jack cheese. Repeat this layering with the remaining batter, peppers, and cheese.
-
Bake: Bake the casserole in the preheated oven for about 30 minutes, or until it has puffed up and is golden brown. Allow it to cool for 5-10 minutes before slicing.
-
Make Sauce: In a cast iron skillet, sauté diced Roma tomatoes, chopped yellow onion, jalapeño, and garlic until charred and softened. Blend this mixture with chicken bouillon, oregano, and a bit of water until smooth.
-
Serve: Spoon the homemade sauce onto a plate, add a delightful slice of casserole on top, and finish with a sprinkle of fresh cilantro.
Optional: Serve with lime wedges, avocado slices, or a dollop of sour cream for extra freshness.

Easy Chile Relleno Casserole Recipe FAQs
How do I choose the best poblano peppers?
Absolutely! When selecting poblano peppers, look for ones that are firm and smooth, with a deep green color. Avoid any that show signs of wrinkling or dark spots. The best poblanos will have a slightly shiny skin, as this indicates freshness.
How should I store leftovers of the casserole?
For optimal storage, place leftovers in an airtight container and keep them in the refrigerator for up to 3 days. Reheating in the oven at 350°F (175°C) will help retain the casserole’s fluffy texture and melty cheese, making every bite delicious!
Can I freeze the Easy Chile Relleno Casserole?
Yes! To freeze, assemble the casserole without baking it. Wrap it tightly in plastic wrap, then in foil, and store it in the freezer for up to 2 weeks. When ready to bake, thaw it overnight in the refrigerator before cooking it as per the recipe.
What if my egg whites don’t reach stiff peaks?
If your egg whites aren’t whipping into stiff peaks, ensure your mixing bowl is completely clean and free of any grease or eggshell. Adding a pinch of cream of tartar can help stabilize them. If they remain soft, it won’t affect the casserole’s flavor, but it will reduce fluffiness.
Are there any allergy considerations for this recipe?
This casserole is vegetarian-friendly, but make sure to check for any allergies regarding the ingredients like eggs and cheese. For gluten-free folks, simply use gluten-free flour in place of all-purpose flour. Always double-check labels on store-bought ingredients to avoid cross-contamination.
Can I substitute other ingredients for dietary needs?
Very! For a dairy-free option, you can use plant-based milk and cheese; just be sure to check that your substitutes are suitable for your dietary needs. If you’re looking to cut down on spice, there’s always the option to omit the jalapeño or replace it with a sweet bell pepper for a milder flavor.
