When I decided to make this for dinner I knew I needed another jalapeno to slice to put on top. So, I called my husband and asked if he could stop at the farmer's market. He said yes. Great. And then he was late. So I had to bake the Jalapeno Popper Chicken Casserole without the sliced jalapenos on top. Not a big deal until I topped it with raw ones and he said, "You know you aren't supposed to serve raw jalapenos? You should blanch those first."
Since then we have explored other types of peppers and ways to use jalapenos. Make sure to try my Low Carb Jalapeno Popper Dip, Bacon Jalapeno Poppers, and my Keto Chile Relleno Casserole.
How to Cook Chicken for Casseroles
To cook the chicken for this jalapeno popper chicken casserole I put it in a 9 x 13 casserole dish, cover it with foil, and bake at 350 for about 45 minutes until it is 160 degrees on a meat thermometer. These were huge chicken breasts. You may need to adjust the time depending on the size of your chicken.
The main trick for chicken casseroles is not using dry chicken. Make sure to take the chicken out of the oven once it reaches 157 degrees and let it rest to go up to 160. That way your chicken casserole will not be dry!
Alternatively, you can always used shredded chicken from a rotisserie chicken or just leftover chicken instead.

Second Step: Pour the casserole mixture into a casserole dish. Add some more bacon, shredded cheese, and sliced jalapeños on top.
Third Step: Bake the casserole at 350 degrees for 35 minutes. When it’s bubbly and hot, it’s ready to serve. It pairs well with a side salad.

Can I Double This Recipe?
Yes, of course, you can double this jalapeno popper chicken casserole recipe. I will let you know that this makes 8 servings that will feed a whole crew of hungry people. So depending on how many people you are cooking for, you will just need to double or triple the ingredients.
The jalapeno chicken casserole will last in the fridge for 3-4 days, so it’s easy to make in advance too. Before serving, just warm it up in the oven or microwave, and you will be all set.
Is This Chicken Casserole Spicy?
No, the jalapenos don’t make this jalapeño popper chicken casserole spicy. As jalapeno peppers are seeded, then diced they lose a lot of their heat. They are delicious but don’t give you lots of spice and heat. If you want it to be spicier, you can add more jalapenos, some cayenne pepper, or even some red pepper flakes to the dish.

- Cheddar Cheese - Cheese is more than just the most amazing topping for almost any meal! It’s also full of vitamin A, calcium, phosphorus, and zinc.

Raw Jalapenos vs Cooked Jalapenos
I'm not a big fan of very spicy food. I like a little kick but not having my mouth hurt. Cooked jalapenos are milder than raw jalapenos. We really like roasted jalapeno.
Both are edible, raw jalapenos are used in salsas a lot, but these jalapeno slices were supposed to be baked on top of the casserole.
But I really wanted to share this with you today. And my kids really wanted dinner at the usual time. So it got topped with raw jalapenos. Que Sera, Sera. I can hear my grandmother singing it in my head whenever I think of that song.
What should I serve with Jalapeno Popper Chicken Casserole?
I like to serve this with a green salad with my Paleo Ranch Dressing but any non-starchy vegetable will work as a side dish. Other good choices are Oven-Roasted Green Beans or Keto Cauliflower Potato Salad.
If you enjoy a little kick to your food (and you probably do since you are looking at a jalapeno recipe after all) make sure to try my Jalapeno Popper Hasselback Chicken and my friend Sarah's Buffalo Chicken Casserole over at My Montana Kitchen!
For a milder flavorful casserole, my Keto Philly Cheesesteak Chicken Casserole can't be beaten!

Creamy, chicken-y goodness! We loved this casserole. I did leave the seeds in my jalapeno for a spicy kick, but otherwise made everything just as your recipe is written. Scrumptious!
cindy says
This casserole is delicious! I like to add cooked broccoli to it, to sneak a few more veggies in, and that also makes it a one dish meal! My family really likes it!! Thanks for the tasty recipes, Taryn!
Cindy A Rose says
GREAT RECIPE!!! Similar to another recipe I cook, I thought I would pass it along....it has Ritz Crackers crushed on top, I'm going to try the next time! I made frozen Carrots, Broccoli & Cauliflower mix, as well as Garlic Butter! Not Keto I'm sure 😊 but OMG, GREAT!!! Other reviews comment about adding into casserole, good ideal, will try that, as well!! Very versatile casserole!!- THANK YOU!!
Deb says
I LOVE this recipe!!!!!! I add onions and pre-cook chicken then chop it up!
ME says
Did you shred the chicken?
Taryn says
No, I just cut it into bite-sized pieces. You can shred it if you prefer.
Keenetha says
OMG I cooked this but I put some broccoli in it and it was sooo delicious!! Thanks so much for such a great recipe!!
Jana Gunter says
I'm thinking about adding a couple of eggs to this recipe, to fluff it up and add a little more substance. Would that work out? And would it affect the freezablitly?
Taryn says
I've never put eggs in any of my casseroles so honestly, I'm not sure. Eggs are used in ricotta based lasagna filling so I think it would work.
Angie says
This is so amazing. I have made it 3 times now. It's a cinch to make and delicious.
Merry says
This was very tasty. I used a little less jalapenos because I didn't want it too hot. Next time I'll use the full amount. I even got my very picky husband to try this for dinner tonight and he gave a thumbs up!!
Tina says
My family loves eating this wrapped in a tortilla! (Low carb tortilla for myself)
And we add the bacon to our wraps cause we are all about crispy crispy bacon! 🙂

Happy Forks recipe analyzer has this at 4.64 g of carbs per serving
Taryn says
Most recipe calculators vary a bit. If you prefer to use that one that is fine by me. I try to provide nutrition data as a courtesy. User-generated databases can be very off. MFP was defaulting garlic powder to be over 100 grams of carbs per tsp.
