How to Make Cheesy Chile Relleno Casserole
-
Preheat your oven to 375°F (190°C). This initial step ensures a perfectly baked casserole with golden edges.

Roast the poblano peppers directly over the flame or under the broiler until the skin is charred. Cover them with a dish towel or plastic wrap to steam for about 10 minutes, which makes peeling easier.

Sauté the diced onion in a drizzle of olive oil until it becomes translucent, about 5 minutes. Add the minced garlic and sauté for another minute until fragrant.
-
Whisk together the eggs and milk in a bowl. Add in the ground cumin, chili powder, salt, and pepper, mixing until fully combined.
-
Combine the chopped poblanos, black beans, corn, and half of the cheeses into the egg mixture. This will create a deliciously cheesy and hearty filling!
-
Pour the mixture into a greased baking dish, then top with the remaining cheese. It’s time to give this casserole its cheesy crown!

Cheesy Chile Relleno Casserole Recipe FAQs
How do I know when my poblano peppers are ripe?
Absolutely! When selecting poblano peppers, look for ones that are firm and have deep green color without dark spots or wrinkles. They should feel heavy for their size, which indicates good moisture content. If you prefer them spicier, opt for slightly shinier, greener peppers.
What’s the best way to store leftovers of Cheesy Chile Relleno Casserole?
To keep your casserole fresh, store leftovers in an airtight container in the refrigerator for up to 3 days. Just make sure it’s cooled down before sealing it up. When you’re ready to enjoy it again, reheat in the oven for the best texture – I recommend at 350°F (175°C) for about 15-20 minutes until heated through.
Can I freeze Cheesy Chile Relleno Casserole?
Yes, you can freeze this delightful casserole! Wrap it tightly in plastic wrap followed by aluminum foil to prevent freezer burn. It will last for up to 2 months in the freezer. When you’re ready to eat it, let it thaw in the refrigerator overnight, then bake at 350°F (175°C) for 30-35 minutes until it’s hot all the way through.
What if my casserole doesn’t set properly while baking?
Very frustrating, I know! If your casserole isn’t setting, ensure your eggs are fresh and properly whisked for the right texture. If it still seems too runny, it’s possible it needs a bit more baking time. Just keep an eye on its surface; look for that golden-brown color and puffiness, which are great indicators that it’s ready.
Are there any dietary considerations for this recipe?
Definitely! This casserole is vegetarian-friendly, making it a great option for those avoiding meat. If cooking for someone with dietary restrictions, consider replacing the eggs with a vegan egg substitute (about 1/4 cup for each egg) and using plant-based milk for those who are lactose intolerant. Always be cautious of ingredient substitutions, especially with allergies, to ensure everyone can enjoy this comforting dish!
