Let’s talk about how we make this recipe, shall we?

Ingredients Needed

10 poblano peppers
1 tablespoon olive oil
1 jalapeno pepper, chopped
1 medium onion, chopped
4 cloves garlic, chopped
1 pound fresh tomatoes, chopped (or use canned)
1 teaspoon Mexican oregano
1 teaspoon paprika
1 teaspoon ancho powder (or use chili powder)

Salt and pepper to taste

FOR GARNISH: spicy chili flakes and fresh herbs

How to Make Chile Relleno Casserole – the Recipe Steps

First, set your oven to broil. Slice the poblano peppers in half lengthwise and place them on a lightly oiled baking sheet, skin sides up.

Broil the poblanos about 15 minutes, until the skins char and blacken. They should puff up. Remove, cool slightly, then peel off the skins and discard them along with the seeds and stems. I like to include jalapeno peppers as well, to make it a touch more spicy.

Slice the poblanos into strips and set them aside.

Cook the vegetables. While the poblanos are roasting, heat a 10-inch oven proof skillet to medium heat and add the olive oil. Add the onion and jalapeno and cook them down about 5 minutes to soften them up.

Add the garlic and cook another minute, until you can smell the awesome garlic. One of my favorite smells in the kitchen.

Add the tomatoes, oregano, paprika, ancho powder, cumin and salt and pepper. Break apart the tomatoes and stir. Cook for 10 minutes on medium-low, until the tomatoes soften up and the mixture becomes saucy. You can simmer longer if you’d like. Scoop the sauce into a glass bowl and set it aside for now.

Heat your oven to 350 degrees F.

In the same 10-inch skillet (or you can use a baking dish or casserole dish), spoon half of the sauce into the bottom of the pan.

Layer in half of the roasted poblano strips.

Layer in half of the shredded cheese.

Add the remaining sauce, then remaining poblano peppers, then most of the remaining cheese.

Next, beat the eggs with the remaining cheese and pour the mixture over the top of the casserole.

Bake the casserole for 25 minutes, or until the egg sets and the cheeses are nice and melty.

Remove and garnish with spicy chili flakes and fresh herbs.

Serve it with warmed tortillas. I enjoyed the leftovers the next day, just reheated, popped some onto warmed flour tortillas with hot sauce. Hot sauce is a must!

Boom! That’s it, my friends! Easy enough, right? As I said, everything in one pan. That’s the great thing about casseroles. They’re quite easy yet truly satisfying.

Recipe Tips & Notes

The Peppers. I used poblano peppers here, as they are traditional for chiles rellenos, but you can use Hatch peppers, Anaheim peppers, any larger green peppers that can be roasted. You can also make this with canned green chilies. If you’re looking for a spicier version of this recipe, feel free to bring in a serrano pepper, or a few of them. Or cook down some smaller hotter peppers, like a habanero pepper, when you cook the onion.
The Sauce. Homemade enchilada sauce is GREAT here. Use a store bought salsa for a quick version. I added some of my fresh chile de arbol salsa to the sauce and it was amazing! Or try this Quick and Easy Enchilada Sauce Recipe. It would also be quite tasty with Ranchero Sauce.
Leftovers. I enjoyed the leftovers the next day – I just reheated the dish, popped some onto warmed flour tortillas and enjoyed them with hot sauce. Delicious!
Additional Ingredients. Want to make this a fuller meal? Incorporate some shredded chicken or cooked ground beef or pork for a protein, or add refried beans to round it out. You’ll get a heartier dinner this way.

I hope you love this recipe as much as I do. As mentioned, it’s great for an anytime meal, but my favorite time to serve it is for brunch. Let me know how you like it. Enjoy!
