    One thing I love about casseroles is how easy they are to put together and make!  This low carb chicken casserole is no exception and to make things even easier, you can use rotisserie chicken.

    I also added cauliflower rice to the casserole to make it a complete meal, filling and hearty!  But let me tell you, the flavors in this casserole are fantastic!

    I use all the classic ingredients of jalapeño poppers, including bacon!  I even add a little bacon grease which gives it great flavor and adds more healthy fats.

    How to Make Keto Jalapeño Popper Chicken Casserole

    Preheat oven to 375F.

    Fry the bacon in a skillet until crisp, then chop the bacon into small pieces. Reserve 1 tablespoon of the bacon grease and some of the bacon (for the topping).

    Tips for Making the Best Low Carb Chicken Casserole

    • The chicken that I used was cooked chicken breast that I shredded.  You can use any part of the chicken that you like and to save time, you can even use store bought rotisserie chicken. Just be sure you buy organic, if possible, without antibiotics or hormones.
    • Cauliflower rice is best to use, but if you prefer larger chunks, you use them instead. I used fresh cauliflower and it cooked perfectly in the 40 minutes that mine took to bake.
    •  If you want to use frozen cauliflower, I would definitely thaw it out and squeeze out the moisture first, but note that the texture might be softer, since it's pre-cooked.
    • I used uncured bacon, fried and chopped into small pieces.  I reserved a small amount to crumble over the top as a garnish, but this step is optional. A tablespoon of the bacon grease went into the mix because it really adds a nice bit of flavor.
    • Leftover Jalapeno Popper Keto Chicken Casserole freezes well. Use an air tight freezer safe container and store in the freezer up to a few months.

    Substitutions for Jalapeno Keto Chicken Casserole

    • If you don't have fresh jalapenos, you can certainly use the jarred kind instead but I think you will have better flavor using the fresh.  
    • I used 3 large fresh jalapeño peppers, that I seeded and removed the ribs from, then chopped.  This amounted to just over ½ cup once I chopped them up.  If you prefer more heat, you can either leave the seeds and ribs in or use 4 large peppers instead.
    • I used sharp cheddar cheese in this casserole, that I shredded myself.  If you don't have time to shred it yourself or already have pre-shredded on hand, by all means use what you have.  
    • If you prefer Colby, Monterey Jack or even Pepper Jack you can use that instead or even a combination of these cheeses would work perfectly.
    • Cream cheese is pretty essential for jalapeño poppers, so that's what I used in this recipe. If you prefer milder flavored mascarpone cheese, you can use it instead, and even save on some of the carbs.

      Excellent!
      I live alone and usually have rotisserie chicken on hand. This is my favorite use for the leftovers. I usually send some home with my son too so we can both enjoy it. Thank you!

        You will need to thaw it overnight in the fridge first. Then you can reheat it in the microwave or covered in a preheated oven.
