Ingredients for Your Creamy Low Carb Chicken Casserole
Let’s talk about what goes into this glorious dish! I’ve found that using simple, everyday ingredients is the best way to get that amazing flavor and creamy texture. You probably have most of these already in your pantry or fridge, which is always a win on a busy night!
The Casserole Mix
This is where all the good stuff comes together. We need about 4 cups of cooked shredded chicken – leftovers are perfect here! Then, we toss in 2 cups of cooked spaghetti squash. Trust me, the squash adds this fantastic texture without adding any carbs. And for that cheesy goodness? We’re adding 1 cup of shredded mozzarella cheese and then a little sprinkle of 1/4 cup of bacon crumbles for that smoky crunch. Yum!
The Luscious Sauce
This is the secret to the “creamy” part! You’ll need 4 ounces of softened cream cheese – make sure it’s truly soft, it mixes so much better. Then, grab 1/2 cup of your favorite mayo and 1/2 cup of sour cream for that tangy richness. For flavor, we’re going big with 2 teaspoons of garlic powder, 2 teaspoons of onion powder, 1 teaspoon of salt, and 1/2 teaspoon of pepper. Whisk it all together until it’s super smooth!
The Irresistible Topping
To finish it all off, we’re adding another layer of deliciousness on top. Sprinkle on 1 cup of mozzarella cheese and then another 1/2 cup of bacon crumbles. Finally, a little garnish of 1 tablespoon of chopped fresh chives really makes it pop. It looks as good as it tastes!

Give it a good stir until it’s all creamy and smooth. Then, gently fold in your cooked shredded chicken, that lovely spaghetti squash, 1 cup of the mozzarella cheese, and that 1/4 cup of crunchy bacon crumbles. Make sure everything is nicely coated!
Step 3: Assemble and Top
Spread this glorious mixture into your prepared baking dish. It should fill it out nicely. Then, top it off with the remaining 1 cup of mozzarella cheese – get that whole surface covered! And for that extra bit of smoky goodness, sprinkle on the last 1/2 cup of bacon crumbles. Don’t forget to finish it with the chopped chives for a pop of color and fresh flavor.

Pop that beautiful dish into your preheated oven. You’ll want to let it bake for about 30 minutes. What you’re looking for is for it to get nice and hot, with the cheese all melted and bubbly. That’s your sign it’s ready to come out and be devoured!
Tips for the Ultimate Creamy Low Carb Chicken Casserole
Okay, so you’ve got the recipe, but let’s talk about taking your Creamy Low Carb Chicken Casserole from “good” to “OH MY GOSH, THIS IS AMAZING!” A few little tricks can really elevate it. First off, don’t skimp on softening that cream cheese! If it’s not soft enough, your sauce will be lumpy, and nobody wants that. I usually pull it out 30 minutes or so before I start mixing. Also, chicken that’s already cooked and shredded is a lifesaver, but if you’re cooking chicken breasts from scratch just for this, don’t overcook them! Dry chicken equals dry casserole. For some extra pizzazz, consider adding a pinch of smoked paprika to the sauce – it gives it a lovely depth. And hey, make-ahead is your friend! Lots of veggie side dish recipes can be prepped ahead too, making your weeknights even smoother.
Ingredient Notes and Substitutions
Let’s chat about ingredients for a sec! Because this Creamy Low Carb Chicken Casserole is so flexible, you can totally swap things around. If you’re not a huge fan of spaghetti squash, no worries! Broccoli florets or cauliflower florets that have been steamed or roasted until tender are fantastic substitutes. They add a great texture and soak up that creamy sauce like a dream. Cheese-wise, while mozzarella is the classic melt-y choice, feel free to mix in some cheddar or even a touch of Monterey Jack for extra flavor. Just make sure whatever you use melts well!
Serving and Storing Your Creamy Low Carb Chicken Casserole
This Creamy Low Carb Chicken Casserole is practically a meal all on its own, but if you want to round it out, a simple side salad with a light vinaigrette is fantastic. Or, just whip up some extra steamed green veggies! Leftovers are pretty amazing, too. Just let the casserole cool completely, then pop it into an airtight container and store it in the fridge for up to 3 days. When you’re ready to reheat, you can zap it in the microwave for a minute or two, or pop it in a 350°F oven for about 10-15 minutes until it’s nice and hot again. Easy peasy!

Precision Keto Scientist
Numbers don’t lie, and neither do my recipes. I’m a biochemist who fell into keto cooking through my own metabolic research—and I approach recipe development like a lab experiment, complete with macro calculations precise to the tenth of a gram.
My journey started in diabetes research labs at Johns Hopkins, where I spent six years studying how different macronutrient ratios affected insulin sensitivity. Personal experimentation with therapeutic ketosis for cognitive enhancement led me down a rabbit hole of recipe testing that eventually consumed more hours than my actual day job.
While other cookbook authors describe flavors and textures, I quantify ketone elevation curves and glycemic impact data. My recipe database contains 340+ formulations, each tagged with detailed nutritional analysis, predicted ketosis timing, and optimal meal spacing. I measure salt by weight, time cooking processes to the minute, and log ingredient sourcing obsessively for consistent results.
My breakthrough research on fat-protein ratios for sustained ketosis got published in the Journal of Nutritional Biochemistry. My “Macro Math Mastery” workshops have trained over 5,000 people in precision meal planning. I even collaborated with continuous glucose monitor manufacturers to create the first real-time feedback system for recipe optimization.
I left my pharmaceutical research position at Merck three years ago to focus on metabolic nutrition consulting. Now I work with professional athletes, biohackers, and medical professionals seeking therapeutic ketosis protocols. When I’m not in my lab-kitchen, I’m competing in chess tournaments or documenting my daily biomarker measurements with true data scientist obsessiveness.
Cooking is just applied chemistry—and chemistry follows predictable rules. Master the variables, control the outcomes.
