Cauliflower – Fresh is best, in our opinion. Chop a head of cauliflower into macaroni sized pieces for this recipe.

Chicken – Some cooked, shredded chicken is just the sort of thing we make ahead of time to keep on hand for recipes like this! Check out this easy crockpot shredded chicken recipe if you need some tips on pre-cooking the chicken. A rotisserie chicken would work too!

Jalapenos – For a more mild dish, remove the seeds and membranes from your peppers before chopping. For extra spice, leave them in.

Cheese Mix – This keto jalapeno popper casserole is loaded up with lots of cheesy flavor! You’ll make a cream cheese mixture with some heavy cream and chicken broth, and also pile on shredded cheddar cheese before baking!

Bacon – Crispy fried bacon is the perfect topping for this casserole.

Why We Love This Recipe:
  • This is reminiscent of our favorite jalapeno popper dip, but it’s been turned it a full meal.
  • This is great for meal prep! Portion it into containers and reheat all week long for lunch.
  • It’s easy to make this extra spicy (leave in the seeds and add cayenne) or tone it down (remove the pepper seeds or use a jar of tamed jalapenos instead of fresh).

Helpful Tip!

Too spicy, or not spicy enough? Spicy doesn’t mean the same thing to everyone, so feel free to adjust the amount of jalapeno that you use in this recipe. A sprinkle of cayenne will add extra spice too!

Keto Jalapeno Popper Chicken Casserole

This jalapeno popper casserole is loaded with chicken and cauliflower coated in a creamy jalapeno sauce. We top it all off with bacon and cheddar for the perfect meal.

Yield 6 servings
Prep Time 15 minutes
Cook Time 25 minutes
Total Time 40 minutes


  • 1 medium head cauliflower
  • 2 cups cooked chicken, shredded or chopped
  • 8 ounces cream cheese
  • ½ cup heavy cream
  • ¼ cup chicken broth
  • 4 jalapeno peppers, diced
  • 2 teaspoons garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon salt
  • 1 1/2 cups shredded sharp cheddar cheese
  • 1 cup crumbled fried bacon


  1. Preheat the oven to 350 degrees. Spray a 9x9 baking dish with non-stick spray.
  2. Chop the cauliflower into small pieces, about the size of macaroni noodles. Alternatively, rice the cauliflower.
  3. Bring a pot of water to a boil. Add the cauliflower and boil for 4 minutes.
  4. Drain the water from the cauliflower and place in a large bowl with the chicken.
  5. In a small bowl stir together the cream cheese, heavy cream, chicken broth, jalapenos, and seasonings. 
  6. Stir the cream cheese mixture into the cauliflower and chicken to combine. Pour into the prepared baking dish.
  7. Sprinkle with the cheddar and crumbled bacon.
  8. Bake for 20 minutes, or until hot and bubbly.
  9. Serve hot. 


To make the dish less spicy, remove seeds and membranes from the jalapeno peppers before chopping. For extra spice, leave the seeds and membranes in and add cayenne pepper to taste.

We prefer to chop the cauliflower by hand into macaroni sized pieces - it mimics pasta well in this dish. Cauliflower rice will work as well, but it does get a bit mushier in texture.

  1. I’m assuming we could use frozen rice cauliflower? If so, any idea how many ounces/bags?

      Hi Marie! I’m sure you could use broccoli, but not sure how that will be flavor-wise. I’ve only made this as directed.

  2. To make this even easier I buy the Publix Jalapeño Popper Dip , and the Publix already cooked sliced chicken breast and I put the sliced pre cooked chicken breast in the bottom of my casserole dish then put the entire thing of the Publix jalapeño popper dip on top and spread it out then I put an entire package of bacon that I cut into chunks on top then top with shredded cheese typically mild cheddar and mozzarella and top with more chunks of bacon , cover with aluminum foil and bake at 350 for 25-30 minutes and it’s absolutely amazing!!! Plus the entire prep time is like 3 minutes lol and seriously everyone I’ve ever made it for begs me for the recipe and it will literally be the best thing you’ve ever tasted

  3. Yummy! This will be a go to recipe for cold winter nights. Had to make some substitutes since I live in the middle of no where.
