The Best Keto Chicken Casserole Recipe

Cozy comfort food minus the carbs? This keto chicken casserole is your answer. 

Casseroles are a cross between a stew and a baked dish, and this one is based around chicken breasts or thighs. You can use whichever low carb vegetables you like, including butternut squash, Brussels sprouts, and onions. 

Topped with cheese and baked until golden and bubbling, this casserole is kid friendly and requires little prep.

We baked everything in one dish and the cleanup is almost non-existent. Seriously, you’ll laugh at how hands-off this dish is.

Ready in just 20 minutes, this makes for a fabulous keto dinner that you’ll add to your list of favorites. 

Oh, and each serving has just 3 grams of carbs! Mop up the juices with some keto rolls or toasted keto bread and STILL have the carbs down!

Ingredients needed

You’ll love the simple and easy ingredient list needed to make this recipe. You probably have everything in your kitchen right now and if not, they can be easily found at any grocery store. Here is what you’ll need:

  • Chicken breasts. Skinless and boneless fillets chopped into bite-sized pieces (around an inch in thickness). 
  • Salt and pepper. To taste. 
  • Olive oil. Any oil works. 
  • Vegetables. We used onions, garlic, Brussels sprouts, and butternut squash. 
  • Spices. Cozy and warming spices like cumin and smoked paprika. 
  • Chicken broth. Also known as chicken stock. Try to choose a good quality broth for the best flavor. 
  • Cheese. Any good cheese that melts well, like mozzarella or gruyere. 

How to make a keto chicken casserole

Simple is an understatement for this recipe. The casserole dish does all of the hard work, and you simply follow a 3-step process to set everything up. Ready to whip it up?

Step 1-Par-bake the vegetables

Start by adding the vegetables, spices, and olive oil into a baking dish (casserole dish), cover, and bake until the vegetables are fork tender. 

Step 2- Sear the chicken

Next, season the chicken with salt and pepper and cook in a skillet for several minutes until no longer pink and almost cooked through. 

Step 3- Bake everything together

Now, remove the baking dish from the oven and stir through the chicken. Cover with cheese and bake until it’s bubbling and nicely melted.

Can you cook raw chicken in a casserole dish? 

Unless all the vegetables are of the chunkier variety (think cauliflower, pumpkin, carrots, or rutabagas), it’s not recommended as you risk the chicken being undercooked.

Also, the chicken releases juices into the casserole, which will become watery and lack flavor. 

What to serve with low carb chicken casserole

Growing up, we enjoyed our casseroles with French bread or dinner rolls. As these aren’t keto friendly, we have some go-to sides we’ve been enjoying that work just as well, if not better:

  1. Im going to try this as it looks great. The photos show something like raisins or cranberries that kind of look like they could have been baked in???? Or did you just sprinkle for color in the pics. I do not see anything like that listed in ingredients. Could you comment pls

  2. Hubby and I like Brussels Sprouts, but the grandkids don’t. But if I shred them into very thin ribbon-strips and quickly sauté them with some bacon, I can put them in almost anything and the kids will eat them gladly – I think they think it’s sautéed cabbage, and I’m not telling them otherwise unless they ask.
    I don’t see why that method wouldn’t work here, as a bed under the rest of the ingredients perhaps. I wouldn’t saute them more than a *very* quick ‘Jamie Oliver’ type of “let-it-hit-the-pan-for-30-seconds” sort of saute, because the baking time will overcook them otherwise. Overcooked Brussels Sprouts have a very strong flavor and is the usual reason people don’t like them…
