Jalapeño poppers are so yummy. So is bacon. And this keto chicken casserole combines the two for the perfect low carb dinner treat! (Also works as a Trim Healthy Mama S meal.)

Easy Keto Chicken Casseroles: A Great Dinner

Low carb chicken recipes are popular for those on the keto diet, especially for those with families. Chicken is a frugal meat to include in your meal plan, its flavor lends itself well to a variety of styles, and most people enjoy it.

Chicken casseroles are an easy, delicious, satisfying way to stay on plan and still only make one dinner for the whole family. This keto broccoli chicken casserole is super easy and very popular here at My Montana Kitchen. And this low carb Alfredo chicken casserole? Not only is it a reader favorite, but my family can't get enough of it!

And the best part is how easy it is to make shredded chicken for your meals when you have an Instant Pot. You can, of course, use store-bought chicken or make it another way, but I love just tossing a couple or frozen chicken breasts into the Instant Pot with salt, pepper, and a cup of water and cooking on manual for 30 minutes. They come out ready to shred every single time.

How To Make Keto Jalapeño Popper Chicken Casserole

Now, onto your creamy keto chicken casserole recipe...are you ready? It's sooo good.

First you'll get your oven pre-heating while you put your casserole together.

In a large bowl, combine your cooked and shredded chicken, cream cheese, sour cream, mayonnaise, part of your jalapeños, and the spices.

Using the paddle attachment on your mixer (or some muscle and a good spoon), mix it all together. Spread it out in a 9x13 pan (no need to grease it).

Once it's evenly distributed in your casserole dish, sprinkle on the shredded cheddar and bacon pieces. You'll bake the casserole for 30-35 minutes and, if you want to brown it a bit more, can broil it at the end. Garnish with the remaining jalapeño slices.

Adjusting The Spiciness Of Your Casserole

Most of the heat in a jalapeño is in the seeds, so to turn the heat down on this dish just remove the seeds when you slice your jalapeño.

If you want more heat, you can add some extra jalapeños or just leave the seeds in. Also, you can add the garnish before broiling to kick it up a notch.

The smoother, greener the pepper is, the less heat it has. If you notice a lot of lines, the pepper plant has undergone stress and your jalapeño will be spicier (source). So check your peppers carefully and choose the one best suited to your preferred tastes!

Serving Your Spicy Chicken Keto Casserole

This casserole is best served right out of the oven for gooey cheesy, creamy texture, and best flavor.

If you want to make it up in advance, it makes a marvelous make ahead meal or even a freezer dinner. Simply cover and store it uncooked, and bake it before serving.

You can keep any leftovers in the fridge for 3-5 days in an airtight container. To reheat simply sprinkle the top with a few drops of water and microwave lightly covered.
