This low carb chile relleno casserole will help you satisfy your Mexican food craving while watching your carb intake. This recipe calls for either canned or fresh peppers (whichever you have). I used diced green chiles because I had them in my pantry. I have also made this low carb casserole with fresh poblano peppers and they were awesome! I roasted them in the oven then let them steam and they were easily peeled. Also, I have made this with and without the ground beef and it's great either way.
What are chiles rellenos?
Chile rellenos consist of roasted poblano or other pepper stuffed and fried. This traditional Mexican dish can be high in carbs and fat due to the batter used when frying.
Why this recipe works
- Short on time? This recipe uses canned green chiles as a time-saver. Feel free to roast your poblanos if desired.
- Unlike traditional chile rellenos, there is no frying! Simply layer ingredients and the egg batter cooks up cheesy and delicious.
- Make it with or without ground beef. Your choice!
🥘 Ingredients
- Ground beef- I use ground round but you may use ground beef if desired.
- Diced onions- fresh or frozen (another time-saver) work equally well.
- Diced green chiles- find these in the Mexican food section of your market.
- Cheese- choose your favorite- cheddar to monterey jack work well.
🔪 Instructions
Photo 1 - Begin browning the ground beef with onions. You may omit this step and leave off the ground beef if you desire. Photo 2- Browned ground beef. Photo 3- Layer the green chiles (fresh roasted and peeled or canned) in a medium size casserole dish. Photo 4- Add the ground beef layer on top of the chiles. (You can omit this step if you are leaving off ground beef) Photo 5- This pic shows you the cheese layer covered with remaining ingredients. (milk and egg mixture) Photo 6- This step involves digging in! I topped mine with salsa and sour cream. A side salad would be the perfect accompaniment.
💭 Top tips
- Make this recipe even more flavorful by roasting a couple of poblano chiles in the oven. Place chiles in a paper bag to steam then peel and use in place of canned chiles. Roasted and peeled chiles can be frozen until ready to use if desired.
- Grate your cheese from a block instead of using pre-grated. You will get a cheesier, meltier (is that a word?) result! Only have pre-grated cheese? No worries- it is fine to use too.
- Use ground beef or ground round- whichever you prefer.

This was so delicious and very easy to make. I used whole roasted peppers mixed with a can of chopped peppers, doubled everything (except for the eggs and milk) and made two layers, OMG, heaven! Thank you for sharing.

The flour and milk add to the carb count! Used heavy cream instead. 10 carbs for me is half of my daily allowance on carbs!
Jan
Can you substitute almond or coconut flour for the flour. Keto doesn’t use regular flour
Charlotte
Hi Jan,
Thanks for visiting Easyhealth! Sorry, I've never used almond or coconut flour in the recipe. I will be sure and try this next time I make the recipe though!
Daniela
So have you tried it with either almond or coconut flour? Does anyone know how many carbs it would be if switching the flour? Is it 10carbs per serving or entire dish?
Sally
The flour is not even needed in this recipe-it is used to thicken the milk mixture.
Using half a cup of cream will do the same without the unnecessary addition of carbs from flour and regular milk.

Smart idea- Thanks for visiting Easyhealth Living!

This is good. Family liked it. Added a bit more cumin & added Mexican spice & garlic salt to meat while cooking.

Very good! Definitely use shredded cheese chunks won’t melt in. Needed more cumin and some onion salt without beef. I doubled it for 9x13 Pan. Helps if there’s spray avocado oil on pan first.
