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.

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. 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.
