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.

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.

    Never mind lol I reread it a third time and see now it says to bake for 20mins. So sorry I’m going blind it seems 😊

    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!

    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.

    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!

    What is avocado mayonnaise ?

    • Martha wrote:

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

    Can this be frozen?

    • Martha wrote:

      Hi Mary – You can…but cooked, creamy dishes like this sometimes separate at bit when reheated after being frozen.
