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.

  3. 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.
  4. Cook over medium heat and stir with a wooden spoon until creamy.

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

  3. 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.

  8. 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!

    1. 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
