This casserole may be my new favorite. Full of flavor and creamy Alfredo sauce, it is sure to please your whole family!
I don’t think you have to spend a lot of time in your kitchen to provide your family with delicious, hearty, and healthy meals. A lot of times all it takes is a little bit of planning and prep time.
Check out my video below to see just how easy it is to make this Alfredo Chicken Casserole.
One of my favorite ways to use my Instant Pot is for cooking chicken breasts.
I simply throw my frozen chicken breasts in the Instant Pot liner, add 1 cup of water, and sprinkle with salt and pepper.
Then I process it for 45 minutes, manual pressure. Sometimes I allow it to NPR (natural pressure release), and sometimes I do a quick release.
(Edited to add: I don't think you have to do it for a full 45 minutes, I've been experimenting, and 25-30 minutes does a good job as well.)
The chicken is so moist and tender, and ready for anything I want to make, like this Healthy Chicken Salad!
I like to cook up a batch of these chicken breasts at the beginning of the week, then I have protein ready for salads, wraps, or easy casseroles, like this Alfredo Chicken Casserole.

Or you may want to check out this amazing Tuscan Chicken Casserole from my blogging buddy Taryn, over at Joy Filled Eats!
But this Alfredo casserole may top them all. I love the alfredo - the rich, creamy flavor is so rich and satisfying.
This casserole also gets a boost in fiber and vitamins by the addition of cauliflower and spinach.
One thing I especially love about this is that there is no need to thaw either of the vegetables - just throw them in frozen and they cook in the casserole!
Spinach is a powerhouse for such a tiny vegetable - researchers have found nearly a dozen different types of flavonoid antioxidants alone that are present in spinach, in addition to all the other benefits.
Spinach is also quite low in calories, and has an impressive amount of protein (for a vegetable) - almost 1 gram per cup)!
Considering all of this, it is no wonder that spinach is often considered on of the healthiest foods you can eat!
Cauliflower is a good source of fiber, which helps to keep you feeling full for a longer period of time. It is also a good source of Vitamin C and Vitamin K.
However, if you prefer broccoli over cauliflower, you can use broccoli instead (and still feel great about making a healthy choice for your family)!
Just a note about cooking this casserole - I like to broil my casserole at the very end of the baking time to crisp the cheese a bit. So delicious!
Honestly, this could go into a weekly meal rotation and I would be very satisfied! I like to serve it with a large side salad and roasted green beans or Easy Oven Roasted Broccoli.
If anyone in your family is not a fan of the spinach, you can just omit it.

When do you put the chicken in?
Sarah Hardy
I mix it in with the frozen spinach and cauliflower. (Sorry, I missed that step in my instructions.)
Deia
At what point do you add the chicken? Do you mix it in or do you layer it with the cheese mixture?
Sarah Hardy
I mix it in with the frozen spinach and cauliflower. (Sorry, I missed that step in my instructions.)
Linda Kramer
When is the chicken added to the ingredients?
Sarah Hardy
I mix it in with the frozen spinach and cauliflower. (Sorry, I missed that step in my instructions.)
Cecile Steele
I LOVE the flavor of this dish!!! I have two tips : chop your cauliflower into smaller pieces (it helps it to cook evenly) and saute your 1/2 cup of onion in a little butter to soften before mixing it in (the onion was still crunchy even after baking!) I think I may try substituting mushrooms or chopped artichoke hearts for the cauliflower next time!
Sarah Hardy
Good tips, Cecile! Thank you!
Karen
Did you sub the cauliflower out for the mushrooms or artichoke hearts? Both sound good to me. I cook for a group once a week and a couple of them don't like cauliflower. (However I have snuck it in without them even knowing, haha)
Brenda S Catron
Can I use fresh cauliflower and spinach instead of frozen?
Sarah Hardy
Yes - cooking times may need to be adjusted, but it should work fine!
Tina
Oh my goodness!!! Thank you so much for this recipe. I am making it now and I CAN'T WAIT till it's done cooking.
Ellen
Is 45 minutes in the Instant Pot accurate? Seems long. I know you said they are frozen, are they large and bone in?
I'm new at the Instant Pot, but love the idea and want to try this recipe. It looks delicious.
Sarah Hardy
I'm sorry, I should have clarified. I uses boneless skinless chicken breasts. 🙂 It is possible they would be done sooner, but I want to make sure they are cooked thoroughly.
Wendy
This is our go to low carb meal. Everyone who has tried it has asked for the recipe. We love it! Thanks for posting!!!!
Sarah Hardy
I'm so glad you enjoy it!
Gail
How much is in a serving? Or how many servings total?
Sarah Hardy
There are 6 servings in a 9x13 dish.
Lynn
I don’t like chunky stuff, think it would work with frozen cauliflower rice and fresh spinach?
Sarah Hardy
Yes, I believe so!
Jessica
I used cauliflower rice (frozen) and it’s delicious!! This has become one of my favorites.
jo
i actually used the Birdseye riced cauliflower there cheese variety in freezer section...delish!!
Marie Webb
If I were to use fresh spinach, how much would I use? And, the Parmesan in the
green can...is that Kraft's brand? I normally buy the shredded in the deli department.
I guess either kind will work.
Sarah Hardy
Yes, I usually use the Green Can (Kraft is the name brand). I'm sure the shredded variety would also work! If I were using fresh spinach, I would probably start with 3-4 cups.
Melissa McCullough
Made this tonight but subbed hot Italian sausage for the chicken. Yum!
Missy
I would like to start receiving your low carb recipes.
Sarah Hardy
Thanks, I added you! 🙂
Valerie
So when I serve would you guess that a serving size is 1 cup or 1 and 1/2 cup??
Sarah Hardy
I just divide the casserole into six servings - I have never measured how many cups. 🙂
Kim Perez
I just prepared this and popped it in the over - can't wait for it to be done! I took a chance and used fresh veggies - chopped broccoli, spinach, and asparagus. The cheese mixture seemed really thick so I added extra cream to the mixture. Thank you for sharing this! My husband is pacing past the kitchen, just waiting!
Jacklyn Dewey
So amazing and easy! I actually used canned chicken.
Karen
WOW!! This was amazing!! It will be added to my go-to recipes!! I cut up two chicken breasts into pieces and cooked them up in the frying pan and then added it into the casserole (instead of shredded) - will try shredded next time!
Gina
Have you ever froze the left overs? Was considering making it and then when it's cooled, divide the left overs into individual servings and freezing for later meals. Was just wondering how it tasted
Sarah Hardy
No, I have not tried freezing this. I'm not sure how the creamy sauce would reheat. If you give it a try, please let me know how it turns out!
jo
i have frozen this with great success..I let it cool in fridge overnight then wrapped in nonstick foil and popped individual slices in plastic containters...co-workers ravec!!
Heather
We made it tonight and it was really good. I hope I can freeze of the leftovers. Otherwise, I will cut the recipe in half next time.
Brenda
Made this with 1 1/2 lbs. (Lightly sauteed and drained of liquid) Quartered button mushrooms for my vegetarian daughter but fed it to my carnivorous husband and other daughter, too. Big hit!!
Ellen
Loved this! It was quick/easy and most importantly YUMMY! My one comment is the onions I put in it were still crunchy after 45 min. So I might add 15 min. to the cook time, but overall this is a keeper!
Jessica
Would fresh cauliflower be ok to use if I steam a little to soften it first
Sarah Hardy
Yes, I believe so!
Mandi M
Could I use broccoli instead of spinach?
Sarah Hardy
Absolutely!
Liz
Kid tested and approved. I was a little apprehensive but this is amazing! It was a bit juicy in the bottom do you have any tips?
Sarah Hardy
Mine is a a bit that way as well. I think it would cut down on the liquid if you thawed the spinach and pressed all the water out before mixing with the other ingredients. 🙂
Deborah Kaelin
I didn’t have basil so I used 1/4 tsp oregano. The garlic in this recipe smelled divine when I took out of the oven. The taste was just as good. I used to buy frozen entrees that were chicken broccoli fettuccine. I bet this recipe would also be fantastic with broccoli florets added or used instead of spinach.
Sue Bohlin
I just LOVED this! It was helpful to read the comments first. . . So I used a bag of frozen riced cauliflower (which I've been skeptical about, only caring for roasted cauliflower), a bag of fresh spinach, and the meat from a rotisserie chicken. Oh. My. Word! Loved it!
My son complained that it wasn't "alfredo-y" enough for him, only tasting the cream cheese and garlic, but that means mama gets all the leftovers. Fine by me!
You've knocked another one out of the park, Sarah!
Jane Keffer
I used fresh chopped broccoli florets and fresh spinach. Added a little more cream and about 1/4 cup chicken broth so veggies would cook better. This was divine! Great for my low carb lifestyle and to introduce my husband to the plan.
Kristin
Can I substitute something for the cream cheese and heaving whipping cream but still keep the creamy texture and Alfredo flavor? Those heavy dairy items just kill my stomach! I can only go up to whole milk (in moderation) or I want to die.... 🙂
Sarah Hardy
What about yogurt or pureed cottage cheese? I know those are still dairy, but they are a bit lighter than cream cheese and heavy cream?
Deanna Porter
Can you make this ahead and put in the refrigerator for cooking later on? Make it in Sunday refrigerate and bake on Tuesday or Wednesday?
Sarah Hardy
Sure, I think that would work!
Leanne Katz
Could this be adapted to be made in the crockpot (uncooked chicken)?
Sarah Hardy
Yes, I think so! I have not used my crockpot very much since I got an Instant Pot, so I'm not sure about times, etc.
Esther
Oh my goodness, this recipe is a definite keeper! Just made it for dinner tonight. My husband and I loved it. Thank you! How do I sign up for more recipes?
Rose
Please sign me up for your lowcarb recipes..
I am making this tonight!
Vickie
Just wondering...I’m not a huge fan of cream cheese in savory dishes....but I do like in desserts. What are ur thoughts on using sour cream instead of cram cheese? And would that change the fuel from S to a crossover? Or do u have any other suggestions? My husband loves chicken Alfredo but I do not, however I thought I might give yours a try. 😍. Thanks in advance.
Sarah Hardy
In this dish, the cream cheese really lends to the creamy, rich Alfredo flavor (along with the Parmesan, of course). I think you could use sour cream, but it may alter the flavor a bit - but I think it would still be good! (And it would still be an S Fuel.)
Deanna Porter
Could you make it one day refridgerate it and bake it a day or to later?
Sarah Hardy
Absolutely!
Janice Knitt
What about that Neufchatel cheese? I have a friend that hates cream cheese and subs with that.
Sarah Hardy
Yes, I think that would work fine!
christa
This was delicious! My whole family loved it - even the husband that hates cauliflower. (He has no idea it was in it)
I cooked 3 frozen boneless chicken breasts in insta-pot for 25 min. Put chicken in bowl and shredded with 2 forks.
Did not use onions, used 2 cups of frozen cauliflower rice instead of whole cauliflower, added 1 1/2 cups of frozen broccoli instead of spinach.
Dawn
If this doesn't scream comfort food, I don't know what does! Looks unbelievably good and just what I need as the cooler fall approaches 🙂
Wendy
Love the short cuts with the frozen cauliflower, spinach, and rotisserie chicken!
Sues
Oh yum!! This sounds so flavorful and delicious... Now it's all I can think about!
Chelsey
This looks delicious! I'm not big on casseroles, but I might make an exception for this one!
Jay
I rarely comment on recipes but this was really good! My kids complained the whole time it was cooking that I was putting cauliflower in it. They loved it! I did 3 cups fresh spinach as you suggested in one of the comments and sauteed my onions and garlic. I also did a cup of parmesan instead. So delicious! This will be usual here. Thanks!
Sarah Hardy
I'm so glad your family loved it! This dish makes a great low carb family dinner!
Betty Moehle
Super easy, and delicious!
Maryann
Loved this. Followed exactly, but used frozen boneless thighs that I cooked in my Mealthy pressure cooker, for 9 minutes. I turned the heat up a bit in the oven because I couldn’t wait 30 minutes for it to be done and it was perfect at about 25 minutes at 400*
Thank you
Tracy
This was very yummy. Next time I will use fresh spinach instead of frozen (I like the milder taste of fresh) and saute the onion so it isn't crunchy. I will add more heavy cream because we thought it wasn't "saucy" enough. Thank you for the recipe - I can see it lending itself to many variations in my kitchen!
Becky Peters
Substituted broccoli for the spinach and we loved it!
Debbie
I made this tonight exactly per your directions and I thought it was amazing! I liked the cauliflower “big” and I thought the onions were perfect. The flavor is amazing! It was very good! Thank you!!
sherilynn
Made this tonight for dinner and it's a huge hit! I sub broccoli for spinach and used asiago mix cheese instead of mozzarella.
Cheryl
This is absolutely the best chicken casserole ever. My husband could not stop eating it! Thank you so much. Can’t wait to try more of your casserole recipes.
Diana L Gomez
This one was a keeper. Great recipe! I had some left over Sun Dried Tomatoes and a little bit more cream that I added.
Matt
I made this back in June and the family has been requesting it ever since. Making it now and we can’t wait for it to come out of the oven. Adding mushrooms to it is a must! 😆
Darlene
Wow!! Loved this recipe!! I sautéd the onion and garlic until translucent, I used only a half bag of spinach and I used cauliflower rice instead of florets. Cooked my chicken with a little salt and pepper in a pan until just done then cut into small pieces. It was amazing! Will definitely be making this again.
Pat
I added a couple of teaspoons of chicken bouillon to the casserole and it really bumped up the flavor.
Sarah Hardy
That sounds yummy!
Vanessa
Thanks for sharing! Does it keep long?
Penny Severin
Made this for supper tonight and everyone loved it! Thanks for another wonderful recipe!
Crissy
This was delicious! I used a 10 oz bag of frozen cauliflower rice based on some of the comments! I would use two bags next time and maybe some broccoli. I left out the onion! I loved this!
Sues
This is my idea of a dream dinner! So much good stuff in one meal 🙂
Paige
This is a yummy way to eat low carb...would love this with a side salad!
