This low carb Chile Rellenos Casserole has all the flavor of regular chile rellenos, but without the breading and frying.
Once a year, my girlfriend Jelayne has a Chile Rellenos party. Her family is from New Mexico, and her uncle sends a large care package of assorted Hatch chiles. Jelayne and her husband, Dan, spend the afternoon charring, filling, battering and then deep-frying dozens of chiles.
The thing is, she never called them “Hatch chiles”, they were just chiles to her. Because to New Mexicans, Hatch chiles are the only chiles!

Many years later the Hatch chile craze came to Southern California, with roasting events popping up all over the city, and I finally figured that we’d been eating Hatch Chile Rellenos for years, but just didn’t know it.
Now, it’s hard not to miss the word “Hatch” in August and September! There are roasting events all over the country now! If you can’t find a chile roasting event near you, you can roast them yourself.
How to roast chilies
Don’t worry if you don’t have access to Hatch chiles, you can always use poblanos, pasillas, or Anaheim chiles. There are a couple of ways to roast them. First, you can throw them on the grill, no need to do anything to them. Just rotate them until the skin is charred and blackened.
You can also roast them over an open flame, or under the broiler. Then pop them in a brown paper sack and close. Let them sit and steam in the bag for a few minutes, or until cool enough to handle.
If you don’t use plastic gloves to remove the skins and seeds, be mindful of your hands and don’t touch your face or eyes.
The skins should peel of very easily. Scrape the seeds out and remove the stem end. I usually give them a quick rinse and pat them dry with paper towel to get the last bits of skin, seeds and char off.
If you are lucky enough to pick up pre-roasted Hatch chiles, you might want to buy a case. (I did just that last weekend when I bought 10 pounds of roasted chiles from my local grocery store).
What do you do with TEN pounds of Hatch chiles?
Well, I’ve make Hatch Chile and Cheddar Egg Bites, which make a nice grab and go, breakfast that’s low-carb and gluten free. Or this Hatch Chile Bacon Grilled Cheese Sandwich, which is definitely not low-carb! (Spencer gets to eat that!) Or we’ll just dice them up and pop them in omelets or scrambled eggs.
How to Freeze Chiles
If you do buy more chiles than you can possibly use in a week, you’ll want to freeze them.
First pat them dry or lay them flat on some paper towels to absorb some of the moisture. DO NOT PEEL them, the skins will help keep them moist. Freeze them flat in plastic bags and then stack the bags. Once they’re defrosted, the skin should easily slip off.
This low carb Hatch Chile Casserole doesn’t involve any stuffing, breading, or frying, so most of the work is in prepping the fresh chilies. Once you’ve got them skinned and cleaned, it takes just a few minutes to pull the casserole together.
We’ll have this for breakfast, lunch or even as a side dish to go with dinner. Since it’s vegetarian, it also makes a great entree. Did I mention that it works well with a Keto diet too?
