Step 1: Preheat and Prepare

Now for the creamy deliciousness! In a good-sized bowl, let’s get our sauce going. Just dump in the softened cream cheese, mayo, sour cream, garlic powder, onion powder, salt, and pepper. Give it a really good stir until it’s all smooth and lovely. Then, toss in your cooked shredded chicken, that lovely cooked spaghetti squash (remember to drain it well!), 1 cup of that mozzarella cheese, and the first bit of bacon crumbles. Mix it all up gently but thoroughly until everything is coated in that dreamy sauce.
Step 3: Assemble and Top
Ready to make it look pretty? Spread that glorious chicken and squash mixture evenly into your prepared baking dish. Now for the grand finale: sprinkle the remaining 1 cup of mozzarella cheese all over the top, followed by the rest of the bacon crumbles. Finish it off with a nice sprinkle of those chopped chives for a burst of freshness. It’s going to look SO good!
Step 4: Bake to Perfection
Pop that dish into your preheated oven. Let it bake for about 30 minutes. You’re looking for it to be hot, bubbly, and beautifully golden on top – that’s when you know your Creamy Low Carb Chicken Casserole is ready to rock! Seriously, the smell alone is amazing.

Ingredient Notes and Substitutions
Let’s chat about some of the stars of this Creamy Low Carb Chicken Casserole! Sometimes a recipe calls for something a little out of the ordinary, or maybe you just want to swap a few things around based on what you have. No worries, I’ve got you covered!
Shredded Chicken: The recipe calls for cooked chicken, and honestly, using leftover rotisserie chicken is my personal shortcut hero! You can also boil or bake chicken breasts and shred them yourself. If you’re feeling adventurous, leftover shredded turkey works just as beautifully. For more chicken ideas, you might like this easy creamy ranch chicken recipe!
Spaghetti Squash: This stuff is amazing for adding bulk and texture without the carbs. Just make sure it’s cooked until tender and then all the seeds and watery insides are scooped out. If spaghetti squash isn’t your favorite, don’t sweat it! Broccoli florets, cauliflower rice, chopped zucchini, or even sautéed spinach are fantastic low-carb veggie swaps. Just cook them until tender and drain off any excess liquid before adding them to the mix.
Cheeses: We’ve got mozzarella in there for that classic gooey pull, and cream cheese for the ultimate creaminess. If you’re not a fan of mozzarella, a sharp cheddar or Monterey Jack would be delicious too. Just make sure the cream cheese is nice and soft before you start mixing the sauce!

Dual-Restriction Recipe Engineer & Cross-Contamination Specialist
Everything changed when my teenage son got hit with celiac disease and Type 1 diabetes diagnoses within six months of each other. Suddenly, pizza and pasta were off the table, and most “diabetic-friendly” foods contained gluten. I went from regular mom cooking to navigating what I call “compound restriction cooking”—and I had a kid’s appetite and taste buds to satisfy.
Lucky for us, my background in pharmaceutical quality control gave me the systematic mindset this level of precision requires. My kitchen now operates under pharmaceutical-grade protocols adapted for home use: dedicated prep surfaces, separate storage systems, and testing procedures that verify both carb counts and gluten absence before any recipe gets published.
I’ve developed over 220 recipes that clear multiple dietary hurdles simultaneously—finding gluten-free thickeners that don’t spike blood sugar, creating bread alternatives that meet both keto ratios and celiac safety, and developing desserts that actually taste good to a teenager despite impossible restrictions.
Through my “Safe Kitchen Certification” program, I teach other parents that managing multiple dietary restrictions isn’t about multiplying limitations—it’s about systematic thinking that reveals unexpected possibilities. When you engineer solutions instead of making compromises, restriction becomes innovation rather than deprivation.
