Keto Chicken Alfredo Casserole has been my weeknight dinner hero more times than I can count. Some nights, the fridge is suspiciously empty and the energy meter? Well, it hit zero. That’s when comfort food has to show up and do the heavy lifting, like this dish does. Especially when you’re trying to keep things low-carb and still want to feel like you’re eating something kinda special. If you’re already a fan of cozy chicken dinners (get your fix with this easy million dollar chicken casserole) or just want one pan to rule the dinner chaos (try these healthy crockpot chicken recipes if you’re juggling too much), this one’s about to be your new go-to.

Why Make This
Alright, I’ll just say it. Keto Chicken Alfredo Casserole checks so many boxes for busy folks (and snackers like me). You get all those rich, cheesy, creamy vibes—just minus the carb-heavy pasta. Plus, there’s none of that complicated stuff. Seriously, I tried recipes in the past that needed a bazillion steps. No thanks. This one doesn’t, and it still feels like a five-star restaurant treat. Around here, my family basically hovers by the oven when this is baking. It smells that good.
Another plus? There are no weird, expensive ingredients. Just your classic keto staples blended up into pure happiness. Oh, and leftovers? Perfection. I even packed a cold slice for lunch last week. Weird? Maybe. Tasty? Absolutely.

What You’ll Need
You don’t have to turn your kitchen upside down hunting for ingredients. That’s honestly a dealbreaker for me. Here’s what makes this Keto Chicken Alfredo Casserole tick.
Grab shredded cooked chicken (rotisserie makes life easier if you’re in a rush, just like in my favorite cheesy garlic chicken wraps). Cauliflower rice slides in for pasta and soaks up all the creamy stuff. Next, you’ll need cream cheese, heavy cream, and parmesan for that Alfredo magic. Garlic, salt, black pepper, and a little bit of Italian seasoning round it out. Some people sprinkle mozzarella on top. I say go for it. More cheese is always a win.
Oh, and fresh parsley for a touch of something green. Makes you feel like you’ve got your life together. Sometimes, I’ll throw in a handful of baby spinach because, why not? The goal’s to use what’s handy and keep it simple.

How to Make It
Here’s how I tackle this Keto Chicken Alfredo Casserole, real talk style. Start your oven up to 375F. Mix up cream cheese, heavy cream, grated parmesan, minced garlic, spices, and maybe a splash more cream if you’re feelin’ wild, in one big bowl. Mash it all until it’s smooth and dreamy.
Fold in the shredded chicken and cauliflower rice right there. It looks kinda chunky. That’s good. That’s flavor. Scoop everything into a greased casserole dish and sprinkle mozzarella on top. Pop into the oven. Let it bake 25-30 minutes, until it’s hot, bubbly, and golden at the edges. If you’re like me, you’ll broil it for two minutes just to get that cheese extra toasty.
Let it rest a wee bit to set up (easier to scoop, trust me). Serve hot, with extra parmesan and a sprinkle of parsley because, well, that’s what makes it look restaurant nice.
Top Tips
Let’s make sure your Keto Chicken Alfredo Casserole turns out better than you expected, every single time.
First, squeeze out any extra water from your cauliflower rice before it goes in. Trust me on this. If you skip it, you might end up with a watery casserole. Not the vibe.
Second, don’t overcook the chicken before combining. Dry chicken ruins the mood.
Third, taste the sauce before you mix everything together. Some folks like it saltier or cheesier (hi, yes, me).
Last tip: Let it cool a bit before diving in. I know, hard to wait, but it helps the casserole stay together. For more cozy dinner inspo, check out my comforting chicken mushroom soup for chilly nights.

- Pile it high with roasted broccoli or asparagus for a pop of color.
- Add a big leafy green salad on the side.

Looking for More Easy Keto Dinners
When I get bored of the same rotation, I look for recipes that are simple and dependable (less mess, less fuss). If you like dishes that bring people together and go easy on carbs, you’ve gotta try these next:
- Deliciously creamy rotisserie chicken pasta for busy nights works when you’ve got leftover meat and zero patience.
- Deliciously creamy smothered chicken rice for a southern-inspired hug in a casserole.
- Hearty turkey sweet potato casserole for cozy nights if you wanna shake up the protein but keep things hearty.
Each one of these packs that homemade flavor—and trust me, they’ll keep you coming back.
Common Questions
Do I have to use cauliflower rice?
Nope! But it makes the dish lower in carbs and fills the pasta gap. You can use broccoli rice instead, but cauliflower stays creamy best.
Can I prep it ahead?
Yep. Assemble it up to a day before, store in the fridge, and just bake when you’re ready.
How long do leftovers keep?
I usually keep them for three days, max. That’s if you can stop yourself from finishing it sooner.
Can I freeze this casserole?
Sure can! Freeze before or after baking. I just wrap mine well. Thaw overnight, then bake or reheat.
What if I like it extra garlicky?
Add more garlic. There’s no such thing as too much.
