I love ordering chile rellenos at my local Mexican restaurant – these battered and fried stuffed peppers are just SO tasty. Chile relleno casserole has all of the same flavors but with way less work. Serve your casserole with other Mexican food recipes like black beans and rice, avocado corn salad or Mexican coleslaw for a memorable meal.

Every time I go out for Mexican food, I order a combo plate with a chile relleno on it. Those battered stuffed peppers are one of my go-to foods of all time! This chile relleno casserole has many of the same flavors, but in a convenient baked form to feed a crowd, without any deep frying involved.

Chile Relleno Casserole Ingredients

To make this recipe, you will need whole green chiles, Monterey jack cheese, large eggs, milk, flour, baking powder, cheddar cheese, cilantro and toppings of your choice.

How Do You Make Chile Relleno Casserole?

Preheat the oven, then coat a baking dish with cooking spray. Stuff each one of the chiles with a stick of Monterey jack cheese. Place the chiles in a single layer in the prepared casserole dish. Pour the eggs, milk, flour and baking powder into a blender, then blend until smooth. Pour the egg mixture over the chiles in the pan, then add the shredded cheddar cheese on top. Bake until the casserole is golden brown and puffy. Add a sprinkle of fresh cilantro, then serve with any toppings you like.

Tips For The Reliable Dish

I use a blender to make the batter because it’s tricky to get everything to blend together uniformly with a whisk in a bowl. If you don’t have a blender, a food processor will also work.
It’s finest to use freshly shredded cheddar cheese in this casserole. The bags of pre-shredded cheese from the store often contain preservatives and anti caking agents and do not melt well.
Leftover chile relleno casserole will stay fresh in the refrigerator for up to 3 days.
Canned green chilis typically come with most of the seeds removed. It’s always finest to take a quick peek in the chile before you stuff it to remove any stray seeds that might be left behind.
I find this recipe doesn’t need any added salt, as there is already salt in the cheese and peppers.

Quick Tip

If you’re not a cilantro fan, feel free to use green onions instead.

Recipe FAQs

What kind of pepper is used in chile relleno?

The most commonly used peppers for chile relleno are anaheim peppers and poblano peppers. Anaheim peppers are in these photos, and they come conveniently roasted and peeled inside cans in the Mexican section of the grocery store. You can definitely roast your own peppers. Using the canned variety is a lot less work and tastes just as good in my opinion. Hatch chiles are also a good option.

Are chile rellenos spicy?

This chile relleno casserole is not spicy. If you’re looking for a spicier version, you could use a spicy cheese in the filling, or add hot sauce to the batter.
