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

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.

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
This Keto Chicken Cheese Bake is loaded with tender pieces of chicken, mushrooms, bacon and spinach in a decadent cream sauce.
Ingredients
1 pound bacon
8 ounce package cream cheese
1/2 cup grated Parmesan cheese
1 1/2 cups sharp cheddar cheese, shredded
1/3 cup avocado mayonnaise
1 cup heavy cream
1/2 teaspoon hot sauce, we used Cholula
1 teaspoon dry mustard
1/2 teaspoon white pepper
1/2 teaspoon garlic powder
1/2 teaspoon onion powder
1/2 teaspoon paprika
1 store bought cooked rotisserie chicken, meat removed and chopped into bite sized pieces
1 1/2 cups red onion, diced
8 ounces baby bella mushrooms, sliced
1 tablespoon fresh garlic, minced
8 ounces baby spinach
2 cups mozzarella cheese, shredded
Instructions
- 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.

We loved it! The only change I made was that I sprinkled crushed pork rinds on the top for a crunchy topping.
Great idea Mark!
This was absolutely delicious! Thank you!
You’re welcome Amanda! Glad you enjoyed it!
This recipe has made it into our regular rotation for the past year or so. This is one of a very few recipes that hasn’t had numerous changes made to it to make it easier or more palatable. The only change we made to this was to add some horseradish powder which really brought an extra bright note at the end of each bite.
Great suggestion LeAnne!
How much chicken if not using rotisserie chicken?
Hi Cathleen – It’s about 2-3 cups of chicken

Thanks Mark!

Thanks Chris!
I’m planning on making this tonight! Do you know how many net carbs are in each serving? I’m new to this and don’t know how to figure that out. I want to be able to log it in my app I am using. Thanks so much for your help!
Hi Shelley – For any recipe, net carbs is Total Grams of Carbs minus Total Grams of Fiber. So in the case of this 7.7 – 1.5 = 6.2 net carbs
As others have commented, if you don’t like mushrooms the rice caulifower is a fantastic subsitute!
Thanks Jen!
