How to Make the Best Creamy Low Carb Chicken Casserole

Alright, let’s dive into making this absolutely dreamy Creamy Low Carb Chicken Casserole! Itโ€™s honestly so straightforward, youโ€™ll wonder why you havenโ€™t made it a million times already. First things first, preheat your oven to 350 degrees F (that’s 175 degrees C). Easy peasy!

Now, grab a good-sized bowl. This is where the magic sauce comes together. Toss in all those creamy elements: the softened cream cheese (trust me, softening it beforehand makes allll the difference!), your favorite mayo, the tangy sour cream, and all those wonderful seasonings โ€“ garlic powder, onion powder, salt, and pepper. Give that a good stir until itโ€™s smooth and luscious. Next, weโ€™ll fold in the shredded chicken, the tender spaghetti squash, and that first cup of mozzarella cheese, along with those salty bacon crumbles. Mix it all up gently so everything is coated beautifully. Pour this glorious mixture into your greased 9×13 inch baking dish, spreading it out evenly. You want a nice, flat surface for the toppings!

And don’t forget those pretty chopped chives for a little burst of freshness and color. Pop that beauty into your preheated oven and let it bake for about 30 minutes. Youโ€™re looking for that moment when itโ€™s all hot, bubbly, and the cheese is perfectly golden. Oh, the smell! Itโ€™s seriously divine.

Ingredient Notes and Substitutions

First up, the cream cheese and mayo are what give this dish its incredible richness. If you’re trying to lighten it up just a *tiny* bit but still want that creamy vibe, you could try using a light cream cheese or even a full-fat Greek yogurt in place of some of the sour cream, but be aware it might change the texture slightly. For the spaghetti squash, if you’re not a fan or just don’t have it on hand, don’t sweat it! You can totally use zucchini noodles (zoodles) or even just skip it and add a little extra cooked chicken. The goal is deliciousness, after all!
