I’m a Midwestern girl and that means there is one important thing you should know about me…


We have a solid relationship, casseroles and I. We go way back.

And this keto casserole right here is one of the best, if you ask me! Loaded with chicken and bacon, cream cheese and cheddar, and ranch seasoning – what’s not to love? We also snuck in some cauliflower rice to bulk things up and add some healthy veg to the whole dish.

Our spaghetti squash casserole, meatball casserole, and low carb chicken casserole are other family favorites. They’ve all got that cheesy, cozy, comfort food vibe that a good casserole brings to the table.

Ingredient Notes:

ingredients for chicken casserole.

Chicken You’ll need some shredded, cooked chicken for this recipe. Use a rotisserie chicken, canned chicken, or leftover cooked chicken for this one.

Bacon – Fry and crumble up some bacon. We often fry a pound of bacon for breakfast and then pop the leftovers in the fridge to use in our dinner.

Cauliflower Rice – I’m using the frozen, steam-in-bag kind of cauliflower rice you can find at the store. It’s quick and easy! You could also swap this out with cauliflower florets or broccoli florets if you prefer.

Ranch Dressing – You’re going to prepare the ranch dressing yourself using some cream cheese, sour cream, and ranch seasoning!

Cheese – This cheesy casserole recipe gets topped off with lots of shredded cheddar cheese! Mozzarella would also work well in this dish.

Why We Love This Recipe:
  • Ultra rich and cheesy, so this dish is very filling.
  • Loaded with protein from the chicken and bacon.
  • Kids love the flavors of ranch and cheddar, so this is a win with the whole family.

How To:

  • Cauliflower – Microwave the frozen cauliflower rice in the bag for 3 minutes to get it started cooking. It won’t be cooked through, but should be separated into individual pieces after 3 minutes. Drain any excess liquid and add the rice to a mixing bowl with the pre-cooked chicken and bacon.
  • Ranch Dressing – To prepare the ranch dressing you’ll first need to soften some cream cheese. Microwave in a bowl for about 30 seconds or until it can easily be stirred. Add in the sour cream and the packet of ranch seasoning and stir it well until it is fully combined. This easy ranch mix is going to add lots of flavor and creaminess to the casserole! mixing ingredients in bowl.
  • Combine – When you’ve prepared the dressing go ahead and pour it into the mixing bowl with the cauliflower rice, chicken, and bacon. Stir it all up and then pour the mixture into a prepared 9×13 baking dish. Now just start sprinkling the casserole with all that shredded cheddar cheese and it’s ready to bake! casserole topped with cheese.
  • Bake – This keto chicken bacon ranch casserole won’t take long to bake in the oven, only about 20 minutes or until the cheesy topping has melted and the casserole is hot and bubbly! We like to serve it with a drizzle of ranch dressing and some chopped parsley to top it off. Serve it while it’s good and hot!

Helpful Tip!

Keep cooked, shredded chicken on hand for easy weeknight meals like this! We often cook 4-5 pounds of chicken breasts in the crockpot (low for 4-5 hours), shred it all up, and freeze in dinner sized portions in freezer bags. Just grab a bag from the freezer and let it thaw out in the fridge all day before making dinner.


Can I store this casserole?

Cover the dish with plastic wrap or foil and keep refrigerated. Leftovers should keep for 3-4 days.

Can I use fresh cauliflower?

Fresh cauliflower will work great in this recipe. Chop or process the cauliflower into rice sized pieces and place in a microwave save bowl along with 2 tablespoons of water. Cover the dish tightly and microwave for 3 minutes. Drain the liquid and proceed with the recipe.

Make it a Meal!

Serve this casserole alongside a green salad tossed in our keto ranch dressing, keto thousand island, or homemade Italian dressing.

A garlic bread chaffle makes a great side too!

  1. So Yummy, made this tonight, this recipe is a keeper!! Karly you are a girl boss, love your recipes!!!!

  2. Love this recipe! I have doubled the cauliflower and use the frozen Garlic and Lemon cauliflower rice for 1/2… also not a big cheddar fan so I use, provolone and mozzarella with some parm on top. Freezes great and I use for lunches..

    Made this recipe with riced broccoli instead of riced cauliflower and it was delicious. I made baked cheesy ranch chicken years ago, slightly different recipe. However we have to cut the carbs out so that recipe wasn’t an option (it was served on rice or pasta) funny that I didn’t think of using broccoli or cauliflower before! Great recipe, really simple and very filling.

  4. This sounds wonderful! Have you ever made it in a crock pot? I might try it that way. By the way, your recipes are FABULOUS!

  5. Thank you! Looks delicious but I cannot have dairy products…do you think that if I make it without the cheese and sour cream would be good? Thanks again

    1. Karly Campbell

      I can’t really imagine it without the dairy. It would be pretty dry and not much of a casserole, unfortunately. You might try finding some dairy free cheese to use in it’s place.

  6. Hi!! This recipe looks absolutely mouthwatering! By the way, I love your Keto Ranch Dressing recipe (from scratch). Can I use that ranch recipe instead of the traditional packet type? And if yes, how much would I use? Thank you so much ๐Ÿ™‚

    1. Karly Campbell

      Hi Beth! You could use the seasonings from the homemade dressing to mix with the cream cheese and sour cream instead of the packet. Same amounts as called for should be perfect. ๐Ÿ™‚
