Tried & True Baked Chile Relleno Recipe
Have you ever had chile relleno? The authentic version is a poblano pepper stuffed with cheese, dipped into an egg batter, and deep-fried. They are delicious, but takes 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. 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.
The Secret to Chiles Rellenos Casserole
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.
Chile Relleno Casserole Recipe Ingredients
- Peppers - I used fresh roasted poblano peppers. You can use any mild pepper or canned roasted 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

What to Serve With This Baked Chile Relleno Recipe
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.

You can also roast your peppers in an Air Fryer!
Kathy says
Good to know! Thanks for the tip. 🙂
Michelle says
Great Dish! Very quick prep; aside from roasting, peeling/seeding the peppers but that's the part that makes this recipe so delicious. I've made it a few times and the results are consistently good.
Kathy says
Thanks Michelle!!! I do keep some frozen peppers in my freezer that we grow and roast each year. That helps save a bit of time, or I have also roasted the peppers the day before. Glad you enjoy the casserole!
Kathy 🙂
Karen Tober says
Great recipe - followed the directions. I added Salsa Roja and served in a shallow bowl with the salsa roja in the bottom of the dish.
For the salsa roja:
Add tomatoes, onion, garlic, jalapeno, cilantro and salt to a blender. Puree until smooth.
▢6 roma tomatoes, quartered
▢1/2 small onion, halved (yellow or white)
▢3 cloves garlic
▢1 jalapeno, stem and seeds removed (optional)
▢5 sprigs cilantro
▢1 teaspoon coarse kosher salt
Heat olive oil in a small saucepan over medium-high heat. Add blended salsa and bring to a boil.
▢1 teaspoon olive oil
Kathy says
Thanks! And thank you for sharing your salsa recipe! 🙂
Julie says
Hi Kathy! Super recipe! I had about 2 cups of rice I laid at bottom as my poblanos were scant (managed to broil the peppers and alarm the husband/spicy). I also chopped fine a few of the carrots from my pickled jalapenos and put in rice mix. The egg/flour mix came together well and the paprika is attractive and a nice little heat. I only had 6 eggs so the rice def. helped with bulk. I used sliced habanero jack cheese and layered the egg mix/cheese 2x. I baked for 30/350, but added a lid to finish off 7 min and 5 uncovered for a nice brown but still moist.
Was a beautiful finished dish! I also made two different chopped salad salsas served with 1/4 fanned avocado. (fresh green tomato/onion/cilantro and red cabbage, shredded carrot and sliced pickled jalapeno and brine) My goal is to add 5 veggies a day, so I am all set for two 😉
My husband and I have always loved rellenos but have had disappointing results making them at home. We both loved this and imagined other ways to make the base, esp excited about using leftover corn bread/muffins. It would be more like a tamale, tbf but it is a very flexi recipe I know I will use many times. Many thanks!
Kathy says
Thanks so much! You have a lot of great and delicious ideas!
Valerie says
I added raw shrimp cut into one inch pieces. Will try adding black beans and corn shells next time.
Kathy says
Sounds like a delicious addition! 🙂
James says
I added roasted corn and taco meat. Unbelievable!
Kathy says
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.
Kathy
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.
Hill says
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 🙂
Julie says
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!
Julie says
*It takes….🤪
Darryl Towers says
Tthis sounds delicous deffinetly try thin beef be great dish thanks for help
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.

Roberta says
Can I use fresh roasted green chilis instead of poblanos?
Kathy says
Hi Roberta,
Yes, any roasted chile can be used.
Enjoy,
Kathy 🙂
Roberta says
Thank you, Kathy.
I can’t wait to make this for a family Brunch next weekend. BTW, can this be assembled the night before?
Kathy says
Yes! My mother-in-law often makes this the night before. Just plan on baking for an additional 10-15 minutes since everything will be chilled.
Enjoy!
Kathy 🙂
Sherman S. says
I made this verbatim with fresh roasted poblanos. I really enjoyed it. I think next time, and that will be very soon, I am going to attempt doubling the poblanos. And adding some minced Sereno.
Kathy says
It sounds like you like a bit of heat! Enjoy 🙂
Emily says
I haven’t tried this yet, but was wondering what the red pieces are in the photo, almost looks like red bell peppers but I don’t see it in the recipe?
Kathy says
Hi Emily,
Those are just finely diced tomatoes that I use as a garnish.
Enjoy!
Kathy 🙂
liza says
I'm making this for Xmas brunch... I found pasilla peppers and bought them because the grocer told me they were pablanos...just diff name... wellllll they are spicy!!!but cant wait to see how it turns out..may have to use fewer peppers and more cheese : ) : ) .. i roasted them on my cooktop grill. hopefully they are okay but honestly as i was peeling them I had a serious sneezing, runny nose, coughing attack from their aroma.. I'm kinda scared! YIKESss merry merry
Kathy says
Hi Liza,
I hope they aren't too spicy and the dish works out well for you! Fewer peppers will definitely be the key!
Kathy 🙂
Lisa Applebee says
So I made this with the peppers I mentioned in my last post. They turned out to not be too spicy. The overall casserole was not melty cheesy as I imagined it. I attribute this to the use of baking powder. I would not use it again as it was not a consistency that I prefer. I just chopped up the leftovers and added beans, more cheese, mexican crema and poured it over chips! delicious! I also felt like the peppers might be better chopped which probably turns it into a whole different thing and not a relleno. I hope I did the peppers correctly when I charred them but they seemed too meaty left whole to me. I've never made chile rellenos so not the best person to comment!! But I'm glad I tried the recipe! cheers!
Kathy says
Hi Lisa,
Thanks for your comment. Some people do use the finely chopped peppers you can buy, but I prefer the meatiness of the whole pepper.
Kathy 🙂
Dani radford says
Can you make these in ahead of time and then bake later.
Kathy says
Hi Dani,
Yes, this can be made up to a day ahead of time. Prepare casserole, then cover and refrigerate. Pull out of fridge about 30 minutes before baking. You will need to increase baking time by 10-15 minutes.
Enjoy!
Kathy 🙂
amy says
has anyone ever frozen this to be cooked the following week?
Kathy says
Hi Amy,
I have not frozen this prior to baking.
Kathy
Tracy L Leggett says
I just have a question about the Chili's I over-roasted them They are really soft and fall apart can I still use them?
Kathy says
Hi Tracy,
As long as they don't taste burnt or off tasting, they will be fine to use.
Kathy
Tracy L Leggett says
Well they kind of taste bitter...
Kathy says
You might try again with a fresh batch or buy canned roasted chilies if you are out of time. If they taste bitter now, that will be the taste in the casserole.
Fran @ G'day Souffle says
This looks nice and cheesy! I've made Chili Relleno Soup before, and your recipe looks like I could now take it to the next level!
Kathy says
It is delicious! I'm going to need to try the soup! Anything chili relleno to me is amazing!
Valentina says
This is the perfect savory brunch dish. Delicious! No buffet would be complete without it! 🙂 ~Valentina
Jennifer Dzikowski says
Sounds deficits, what do you think about adding shredded chicken?
Jennifer Dzikowski says
*delicious lol
Kathy says
Hi Jennifer,
Shredded chicken would be a delicious addition! Let me know how it turns out.

Mary Ann | The Beach House Kitchen says
I have not had chile rellenos in so long Kathy. This casserole looks incredibly delicious. I have to give it a go!
David @ Spiced says
Ah, I love this recipe! Chili rellenos are one of Laura's favorite dishes - in fact, whenever we go out for Mexican food (which has been quite some time these days), Laura order chili rellenos. I've contemplated making them at home, but never had the gumption to tackle it. This is such an easy way to use those same flavors in an awesome casserole form. Perfect for dinners on cold nights!
Kathy says
One day we will be able to eat out at all our favorite restaurants again! In the meanwhile, making great food at home helps satisfy some of those cravings. I hope this satisfies Laura's cravings for chili rellenos!
