How to Make the Best Creamy Low Carb Chicken Casserole
Now for the fun part! Putting this amazing Creamy Low Carb Chicken Casserole together is honestly a breeze. Think of it like building a delicious, cheesy, chickeny dream house. Seriously, if you can stir things in a bowl, you can totally nail this. I’ve picked up a few tricks over the years from whipping up tons of chicken dishes, like from those air fryer chicken adventures, that make sure this casserole is always a winner. Let’s get cooking!
Step 1: Preheat and Prepare
First things first, let’s get that oven ready! Go ahead and preheat your oven to 350 degrees Fahrenheit. While that’s happening, grab your 9×13 inch baking dish and give it a little grease. A quick spray of cooking oil or a little butter works wonders to keep everything from sticking. Easy peasy!
Step 2: Mix the Casserole Base
In a large bowl, let’s make that super luscious sauce! Combine 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 dreamy. Now, toss in your cooked, shredded chicken, the spaghetti squash, that first cup of mozzarella cheese, and the 1/4 cup of bacon crumbles. Stir it all up gently until everything is coated in that glorious sauce. You want every bite to be packed with flavor!
Step 3: Assemble and Top
Okay, time to build! Pour that yummy chicken and squash mixture into your prepared baking dish. Spread it out evenly so you have a nice, even layer. Now for the grand finale topping: sprinkle on the remaining 1 cup of mozzarella cheese and the other 1/2 cup of bacon crumbles all over the top. Finish it off with those fresh, chopped chives for a little bit of green and fresh flavor.
Step 4: Bake to Perfection
Into the oven it goes! Pop that dish into your preheated oven and let it bake for about 30 minutes. You’ll know it’s ready when the casserole is hot, bubbly, and that cheesy topping is all golden and inviting. The aroma alone will tell you it’s time for some serious comfort food!

Tips for the Ultimate Creamy Low Carb Chicken Casserole
Want to make your Creamy Low Carb Chicken Casserole absolutely, undeniably the best it can be? It’s all about a few little secrets and paying attention to the details. Trust me, these tips will elevate your dinner game!
For starters, don’t skimp on the quality of your ingredients. Using full-fat cream cheese, mayo, and sour cream makes a HUGE difference in that creamy texture we’re going for. And for the chicken? Rotisserie chicken is my go-to because it’s already cooked and super flavorful, saving you loads of time. If you’re shredding your own, make sure it’s cooked through but not dry.
A common pitfall is the spaghetti squash being too watery. Give it a good squeeze after cooking and before adding it to the mix. Nobody wants a soupy casserole! Also, make sure your cream cheese is truly softened; it makes mixing the sauce SO much smoother. A lot of these make-ahead tips are thanks to having a well-stocked keto pantry, which I highly recommend!
Ingredient Notes and Substitutions
So, let’s dive into the little details about some of our star players and what you can do if you need to swap things out! This Creamy Low Carb Chicken Casserole is pretty forgiving, which is why I love it so much.
That spaghetti squash might seem a bit fancy, but it’s basically a low-carb pasta masquerading as a vegetable! If you can’t find it or just aren’t a fan, no worries. Steamed and well-drained broccoli florets or cauliflower rice are fantastic stand-ins. Just make sure they’re nice and dry before tossing them in.
For the dairy lovers, the cream cheese, mayo, and sour cream are what make this casserole so decadent. If you need to go dairy-free, you can try using a good quality full-fat coconut cream (the thick part from a can) instead of cream cheese and mayo, and a dairy-free sour cream alternative. It’ll change the flavor profile a bit, but it’s totally doable!
Making Your Creamy Low Carb Chicken Casserole Ahead
Life gets hectic, right? So, the fact that you can totally get this Creamy Low Carb Chicken Casserole ready to go ahead of time is a lifesaver! It’s a fantastic candidate for meal prep, meaning less stress when dinnertime rolls around.
You can mix everything together, minus the final topping, and store it covered in the fridge for up to 2 days. When you’re ready to bake, just pull it out about 30 minutes before you plan to put it in the oven to let it take the chill off. Then, add that topping and bake as usual, maybe adding a few extra minutes. If you want to freeze it, assemble it in a freezer-safe dish, cover it tightly with plastic wrap and then foil. It’ll keep for about 2-3 months. Thaw it overnight in the fridge before baking.
Leftovers? Oh yeah, they’re great! Store any remaining casserole in an airtight container in the fridge for up to 3 days. Reheat gently in the microwave for a minute or two, or pop it in a 350°F oven for about 10-15 minutes until it’s warm and bubbly again. So good!
