Easy to make chile relleno casserole is as delicious as regular chile relleno but in an easy to make casserole.
Perfect served as a main dish for dinner or even for breakfast or brunch!
Why make this recipe
Have you ever had chile relleno? The authentic version is a poblano pepper stuffed with cheese and then dipped into an egg batter and deep fried. They are delicious, but take a bit of work to get them just right.
I have a much easier version with this chile casserole. This recipe comes from my mother-in-law that she got it from a friend years ago.
I think she's probably been making this for more than 40 years. When you've got something this delicious, it becomes a regular recipe made again and again.
Poblano Peppers
This dish starts with the peppers. The better the peppers, the better the casserole. I used poblano peppers and roasted, peeled and seeded them. Read this post on roasting chile peppers to find out how I roast my peppers.
Using fresh peppers is the best, but they aren't always available or you might be limited on time. I often freeze roasted peppers in the summertime and the frozen peppers can be thawed and used.
You can also buy canned roasted chilies at the store. Try to get the whole chilies, not diced.
Key ingredients
- Peppers - I used fresh roasted poblano peppers. You can use any mild pepper or use canned roasted chile peppers
- Cheese - For this recipe, I used Monterey Jack. Feel free to use part cheddar and part Jack cheese. Pepper Jack cheese would also be delicious and add a little extra spice.
- Milk - Whole milk or whatever you have on hand
- Eggs
Steps to make
- Preheat oven to 350 degrees and lightly spray an 8x11 casserole dish with a nonstick spray
- Slowly whisk flour into milk until smooth
- Add seasonings and baking powder
- Add mixture to eggs and whisk to combine
- Place a layer of chilies in the bottom of the casserole dish
- Sprinkle on ⅓ of the shredded cheese
- Add another layer of chilies and another ⅓ of the cheese
- Pour egg mixture over casserole
- Add remaining cheese
- Bake in preheated oven for 35-40 minutes
- Allow dish to rest for 10 minutes before serving
Serving suggestions
This casserole is delicious all by itself, but you may also want to serve with homemade salsa and guacamole. Some people also like a little dollop of sour cream.
Frequently asked questions
Poblano peppers vary in heat. This dish is mild to medium in heat.

I added roasted corn and taco meat. Unbelievable!

Thank you!
Renee says
I usually use a mix of diced tomato, onions, mixed with salt, pepper, and lime juice and grilled carne asada to stuff my chilis. Do you think if I layered that in there with the chilis and cheese the egg will cook properly over it? Also im thinking of maybe whipping the eggs like I do for my relleno batter, is that a bad idea for this recipe? Thank you! Look forward to making this!!!
Kathy says
Hi Renee,
All of those ingredients sound delicious, but I have only made the recipe as written so I am uncertain how all the extras will work.

Monica says
Renee I hope you tried your idea. I think it sounds great and would totally work as long as you adequately drained your tomatoes...... to much juice may hinder the casserole from properly setting. Don't know about the lime juice, you've already added tomatoes, which are also acidic. cheers.

This recipe is amazing and simple. I desert and roast. Doesn’t take long. I put corn tortillas on the bottom with some oil and crisped while Chili’s were roasting- like a quiche. Served with Tajin and Tony Creole seasoning!! Top with sour cream, fresh tomatoes, and cilantro Big hit at our Sunday brunches. Thanks!
Kathy says
Thank you so much! I appreciate you sharing your tips and am so glad this was a hit! Thanks for your comment! 🙂
Christine says
This is absolutely delicious! I roast and de-seed the poblano peppers in the morning since they are time consuming but well worth it! I added a layer of roasted chicken and black beans. Everyone loves it!
Kathy says
Hi Christine,
Thanks so much! I'm so glad you enjoyed it. Love the idea of adding roasted chicken and black beans!
Thanks,
Kathy 🙂

Ya’ll…this is a delicious dish! I takes a little effort to roast and de-seed the peppers but it’s far superior to the canned chilies. Once that’s done, the rest of it is easy-peasy to make. Everyone in my house loved it…even my youngest, pickiest eater who hates spicy food (FYI, these are not spicy if you choose the correct pepper (poblanos). Make sure to remove all the seeds to ensure no spice remains. I’ve tried this recipe as is, and with diced fajita chicken (mmm, so good) and tonight I’m adding seasoned ground beef; just like the Chile Rellenos at the local Mexican food restaurants near me do (S. Texas). There are literally no left-overs when I cook this dish!

*It takes….🤪
Darryl Towers says

Kathy says
Thanks, Julie!!!
As many years as I've been making this, I've never thought to add chicken or ground beef! Game changer!!! I can't wait to make them again. Thanks so much for your comment.
