This Keto Chicken Cheese Bake is loaded with tender pieces of chicken, mushrooms, bacon and spinach in a decadent cream sauce.

Keto Chicken Cheese Bake

Whether you are eating low-carb or not, who wouldn’t be excited to see this hot and bubbly Keto Chicken Cheese Bake on the dinner table — just waiting to be served?

This Keto Chicken Cheese Bake has a generous amount of chicken in every bite, smothered in a decadent, creamy sauce with baby spinach, bacon, four (!) kinds of cheese, mushrooms and fresh garlic.


Keto Chicken Cheese Bake

If you’ve tried some of my husband Jack’s earlier recipes, then you already know that this easy, low-carb casserole is seasoned to perfection. (He’s SO good at combining different flavors and seasonings!)

The sauce in this dish has been seasoned with Colman’s dry mustard (we love the kick), white pepper, onion powder, garlic powder, and paprika, plus a dash of hot sauce helps cut the richness and adds a subtle bright note.

Keto Chicken Cheese Bake

To make this Keto Chicken Cheese Bake even easier, we used a rotisserie chicken from our local market — but you can roast or poach a chicken at home, then shred or dice it for this recipe.

I will note that this Keto Chicken Cheese Bake is quite rich — but that is one of the hallmarks of a keto diet — and a little goes a long way in filling you up. We suggest serving our Keto Chicken Cheese Bake with a big bowl of salad greens or more fresh spinach on the side.

Keto Chicken Cheese Bake

  • Author: A Family Feast
  • Prep Time: 25 minutes
  • Cook Time: 35 minutes
  • Total Time: 1 hour
  • Yield: 10 servings
  • Category: entree
  • Method: baked
  • Cuisine: American


1 pound bacon

8 ounce package cream cheese

½ cup grated Parmesan cheese

1 ½ cups sharp cheddar cheese, shredded

1/3 cup avocado mayonnaise

1 cup heavy cream

½ teaspoon hot sauce, we used Cholula

1 teaspoon dry mustard

½ teaspoon white pepper

½ teaspoon garlic powder

½ teaspoon onion powder

½ teaspoon paprika

1 store bought cooked rotisserie chicken, meat removed and chopped into bite sized pieces

1 ½ cups red onion, diced

8 ounces baby bella mushrooms, sliced

1 tablespoon fresh garlic, minced

8 ounces baby spinach

2 cups mozzarella cheese, shredded


Preheat oven to 375 degrees F.

In a large skillet, cook bacon to crisp, remove to paper towels and reserve three tablespoons of bacon fat.

While the bacon is cooking, in a medium sauce pan, place cream cheese, Parmesan cheese, cheddar cheese, avocado mayonnaise, heavy cream, hot sauce, mustard, pepper, garlic powder, onion powder and paprika.

Cook over medium heat and stir with a wooden spoon until creamy.

Crumble bacon and add to the cream mixture.

Clean skillet and add two tablespoons of the bacon fat and saute onions over medium high heat for three minutes.

Add the remaining tablespoon of bacon fat and add the mushrooms and saute for five minutes.

Add the garlic and spinach and toss to coat the spinach and cook until wilted, about two minutes.

Add the cream mixture and cooked chicken and heat then pour into an 8X12 inch casserole dish.

Sprinkle on the two cups of mozzarella cheese and bake for 20 minutes.

Place under the broiler and brown, 1-2 minutes.

Let sit ten minutes to set up and serve 10 portions.

There will be a little liquid on the bottom which will eventually absorb into the mixture. We spooned a little over each portion.

    I happened to have a cooked roast chicken in my fridge so prep time was minimal and air fryer bacon only takes 10mins. So I was able to throw everything together quite quickly. It was delicious and filling. Kids found it a little ‘too creamy’ but I loved it. Thanks, I’ll use this recipe again for sure!

      Thanks Isabel!

    Love this recipe! It’s so delicious and fulfilling. I’m entering all the details into my app but I can’t seem to find the weight per serving. Would you happen to have that information.

    • Martha wrote:

      Sorry Lisa – no…the tool we use (Nutrifox) to provide the nutritional information doesn’t include weight, and we ourselves don’t portion a recipe by weight ourselves, just a number of portions.

  • Laura wrote:

    Would you have a suggestion of what I could use instead of cream cheese? Or increase amounts of other things to compensate. Sometimes my stomach doesn’t like it in rich dishes.

    • Martha wrote:

      Hi Laura – Mascarpone cheese is common swap for cream cheese or you could look for some vegan cream cheeses in the specialty section of your supermarket or silken tofu. This is a rich and creamy casserole by design which is why the cream cheese is included, but you could scale that back I supposed add in some sour cream – although the texture will be different and you’ll need to recalculate the fat grams/other macros if you are following a keto diet.

    This was really good. I would definately make again. I did think it was a bit salty though. Thank you for the recipe.

    • Martha wrote:

      Thanks for your feedback Marianne – there is actually no added salt in the recipe, but the bacon/bacon fat may be the cause of that too-salty flavor. You might want to try a different brand of bacon to see if that changes the saltiness a bit, or you could cut back on the amount of bacon fat used. Hope that helps!

  • Noelle wrote:

    This recipe was delicious. I did change a few things. Skipped the bacon and mushrooms and used zucchini. Used sour cream instead of mayo.
    I know that is a lot of changes but this was delicious. Thank you for sharing it.

  • jodi wrote:

    This has really good flavor. A LOT of cheese. Unfortunately, with so much cheese this dish was pooled in grease once done from the oven. It tasted great but left my stomach upset afterwards from consuming so much cheese and grease and left a greasy after taste in my mouth. The prep was also longer than expected. My husband enjoyed it and wants me to make it again but I need to figure out a way for it not be swimming in grease.

    • Martha wrote:

      Thanks for your feedback Jodi – we don’t see an excessive amount of grease ourselves…maybe try a different brand of cheese?

      Hi Mary – We don’t have one – we found the Primal Kitchen brand at our supermarket. I also see Amazon sells a number of different versions here:

      Hope this helps!

    We made this tonight for the first time. My husband and I started a keto diet last week. This meal was a winner! And those who are worried about the cooked spinach, you won’t even notice it. It makes a TON, so we’re going to try and freeze
    some of the leftovers.

    Hello Martha,
    I have made this recipe two times now exactly the way you wrote it and I have to tell you, even if I wasn’t following a keto diet, I would still want this at least a few times a month! This is so decadent and so easy! This reheats nicely and I rarely need anything more than one serving as it is very filling. Thank-you so much for your creativity. I will be back to your site for more ideas.

  • Ellen wrote:

    Can this be made…cooled…portioned…frozen?

    • Martha wrote:

      Hi Ellen – The creamy sauce may separate a bit once frozen and thawed – but if that doesn’t bother you, you could freeze it in portions if you’d like.

    If I use shredded cooked chicken how much should I use?

      Hi Wallace – 1 1/2 pounds or around 3 cups.

  • Susan wrote:

    Where do you get avocado mayo or how do you make it??

    • Martha wrote:

      Hi Susan – Lots of supermarkets sell a brand of avocado mayo from Primal Kitchen. (You can buy it on Amazon, but it’s much less expensive from the supermarket… … if you can’t find it you can swap in regular mayonnaise instead.

  • Janine wrote:

    Absolutely delicious! I subbed broccoli for spinach. Next time I will make the cheese sauce last, as it became very thick and buttery. I’d also leave the dish bake for less than 20 minutes because the cheese got a little too done. Very good recipe, definitely one of my new favorites!

    • Martha wrote:

      Thanks Janine – glad you liked the recipe.

  • Cindy wrote:

    If I only use chicken breast meat instead of a whole roaster bird, how much should be used?

    • Martha wrote:

      Hi Cindy – A rotisserie chicken will give you about a 1 1/2 pounds of cooked meat.

  • Karen wrote:

    I would like to make this tonight; however, all I have on hand is frozen spinach. What do you think? How much should I use? Just thaw and squeeze? Any ideas?

    • Martha wrote:

      Hi Karen – Sorry for not responding sooner. Yes – definitely thaw and squeeze out any excess moisture. In terms of amounts, I’m guessing half a package of frozen but feel free to adjust as you mix the ingredients together.

  • Ginny wrote:

    I was wondering if you’ve made this without mushrooms and it still taste good? I have a family member who can’t do mushrooms, but is really wanting to try this recipe.

    • Martha wrote:

      Sure Ginny – since the mushrooms add some body to the dish, you could increase the chicken a bit.

  • Bri Larson wrote:

    So yummy! Made it last night! My family doesnt do keto with me but they do eat my food and I typically add a carb for them. I made rice to go with theirs and they all said it was to die for! Thanks so much, delicious! Everyone was happy and had a full belly!

    • Martha wrote:

      Thanks Bri!

  • Antwaun Baker wrote:

    Just made this recipe, I’ll be honest, the prep time was more like 45-50 mins, but very tasty. I really needed a recipe with high fat content as it’s really hard to get my fat macros. Other than the prep it takes to make this dish it was great

    • Martha wrote:

      Thanks for taking the time to share your feedback Antwaun – we’re glad you enjoyed the recipe in the end.

  • Barbie Johnson wrote:

    This recipe looks and sounds delicious. We are just not cooked spinach people.
    Any recommendations for using another veggie instead?

    • Martha wrote:

      Hi Barbie – You can use any type of greens that you like – kale, swiss chard, etc – but just keep in mind that those greens take longer to cook than spinach so you’ll need to adjust the cooking time in that step. And, also recalculate the carbs based on what changes you make.

  • Sim @ Sim’s Life wrote:

    Oh I love this recipe! The perfect treat for cold, Winter evenings! I need to be more adventurous with Keto chicken dishes, a bake would be perfect for all the family to enjoy too! I will be looking out for avocado mayo too, don’t think I have seen it in our big Tesco. Would it still be ok just to use normal mayo? Sim x

    • Martha wrote:

      Sure Sim – Avocado mayo has more fat, but regular mayo will work too – just make sure there aren’t any hidden ingredients or sugars that might add some unexpected carbs.

  • Beth wrote:

    I am going to make this week. I was wondering if it will freeze well, once it has been cooked? There are only 2 in my household and with 8 svg we get tired of the food before we eat it all.

  • Nicole T wrote:

    Hello- Do you think I vcan make this with a few chopped up RAW pieces of chicken? Or does the chicken have to be pre-cooked?

    • Jack wrote:

      The thing with chicken is that you should cook it for a short time or a long time or it will be tough. Also in the mixture it would steam and may get tough or not cook all the way through. I would cut up the raw chicken into bite sized chunks and add to the pan when you cook the mushrooms. (Add an extra tablespoon of bacon fat so they cook without sticking). Then just continue on with the recipe.

  • Cindy wrote:

    I made this for dinner last night and we absolutely loved it. Mine turned out very rich and creamy, not runny whatsoever. As a matter of fact, I am going to a get together on Saturday and have been trying to figure out what to take. My boyfriend suggested I halve the recipe (minus the mushrooms and with the chicken cut into smaller pieces) and take it as a dip with crackers or scoops. He couldn’t be more right! I know it will be a hit. Thank you for such a wonderful recipe!

      Great idea Cindy! So glad you are enjoying the recipe!

      No worries Sarah! 🙂

  • Bobbi wrote:

    This is truly super YUMMY! It takes a bit of preparation and seemed really “runny” when I first poured it into the pan – but after the baking and letting it sit for about 10 minutes. It was the perfect consistency. The only change I made was that I made my own chicken by cutting up raw chicken and cooking it in some spices such as paprika and garlic. I highly recommend this dish!

    • Martha wrote:

      Thanks Bobbi!

    I use a carb manager app. How do I track this recipe?

    • Martha wrote:

      I’m not sure I understand your question Shauna. You can enter the ingredients in your carb manager app I suppose, but the nutritional information is also listed at the bottom of the recipe card. That might help.

  • Melinda wrote:

    Do you think this could be made in the crock pot?

    • Martha wrote:

      Hi Melinda – I’m not sure…it uses already-cooked chicken and really, you are just baking it long enough to heat through and melt the cheese. I think the chicken would get overdone and rubbery after hours in a slow cooker. I personally wouldn’t – but if you try it, please let us know how it comes out!

      Hi Kelly – It’s mayonnaise made with avocado oil. You can find it at most supermarkets or Walmart these days.
