Keto Chicken Broccoli Casserole
I have been attempting to simplify the recipes I fix for my family.
That does not mean that I never fix a complicated recipe, but I know that my readers are looking for fast and simple!
When you have been at work all day, you don’t feel like coming home and making a complicated meal for your family. You want something simple and easy!
This casserole fits that perfectly!
Instant Pot Chicken Breasts
I used my Instant Pot to cook my chicken breasts, so they were cooked when I was ready to assemble the casserole.
I usually throw two frozen chicken breasts in my Instant Pot, season with salt and pepper, then add 1 cup of water. I process it at 45 minutes on manual pressure, then quick release (or sometimes I will let it naturally release).
(Edited to add: I don’t think it is necessary to process for a full 45 minutes. Recently, I have only been processing for 25-30 minutes, and they are still cooked through.)
After the chicken breasts have cooked, I shred them with my hand mixer.
(Really, just place the cooked chicken breasts in a mixing bowl and use your hand mixer [or stand mixer] to shred them. Be sure to not OVER-mix or they will turn to mush. But mixing for 10-15 seconds seems to work perfectly!)
All of that to say, my Instant Pot is one of my favorite kitchen tools!
(I absolutely love my Instant Pot!) If you do not have an Instant Pot, put it on your wish List!
An easy, Keto Chicken Broccoli Casserole
This dish took maybe 10-15 minutes to prep (including chopping the chicken and broccoli).
Then just mix everything in a big bowl, dump it in your pan, and put it in the oven! It is so simple!
If you do not have fresh broccoli, some of my readers have commented that they used frozen broccoli and it worked just as well.
In addition, chicken thighs work great to replace the chicken breasts in this recipe. You really cannot go wrong!
Sour Cream may be used to replace the mayonnaise, or you could even substitute some of it with greek yogurt to bump up the protein and reduce the calorie count a bit.
This Keto Chicken Broccoli Casserole is definitely a Heavy S for Trim Healthy Mamas, but totally on plan!
I love my Heavy S meals just as much as the next gal, but I am trying to balance them out with other fuel types as well (Hello FP’s and E’s!)

I like to serve this casserole with a big side salad. Since it already has a vegetable (broccoli) in the casserole itself, I consider the casserole and salad a complete meal!

March 31, 2017 at 5:51 pmCan you use frozen broccoli instead of fresh?
dsdjhardy says
March 31, 2017 at 9:18 pmYes, but it may need to bake a bit longer.
Jen says
September 17, 2017 at 3:18 pmI used frozen and it came out perfectly. Didn’t adjust cooking time at all.
Monica | Nourish & Fete says
April 5, 2017 at 1:19 pmThis looks like terrific comfort food for a chilly day!
Ashley @ Big Flavors from a Tiny Kitchen says
April 8, 2017 at 11:05 pmThis looks like total comfort food!
Sasha @ Eat Love Eat says
April 12, 2017 at 2:12 amMmm, tasty comfort food!
Ariel says
April 26, 2017 at 8:11 amHi, how necessary is the mayonnaise? My boyfriend HATES it, can you taste it in the food?? Would change the taste too much if I didn’t add it?
dsdjhardy says
April 27, 2017 at 2:00 pmI don’t think you can taste it – it just helps to make it creamy. I think you could use equal amounts of sour cream.
Michelle says
August 7, 2017 at 12:21 pmAvocado mayo is a more nutritious alternative to regular mayo and does not taste at all like mayo! That is what we use and it is delicious ?
Jmac says
July 17, 2018 at 6:01 pmYou can’t taste the Mayo. It’s the sour cream flavor that comes out in th this recipe
KC says
May 25, 2017 at 6:46 pmDelicious! Browned chicken with some dry Ranch mix & garlic salt. Added some sauteed shallots, dry minced onion, Italian Herbs & more Ranch mix to the wet ingredients. Definitely a keeper!
Isabelle @ Crumb says
August 1, 2017 at 8:07 pmI’m a big fan of these toss-and-bake casseroles… all you need to make a meal is a simple salad or some steamed veggies, and you’ve got yourself a nice balanced dinner.
It’s too dang hot to turn on the oven right now, but I can see this being a huge lifesaver come the cooler fall weather.
Tina says
August 3, 2017 at 9:26 amI am excited about this recipe, I am always on the lookout for easy chicken recipes. Thanks for sharing!
Felecia says
October 4, 2017 at 6:11 pmFresh broccoli? Does the broccoli ever cook?should I steam it first?
Sarah Hardy says
October 4, 2017 at 8:04 pmI do not steam (or cook) mine at all. If you do not like a bit of “crisp” in your broccoli, you can steam it first. I like my broccoli crisp-tender.
Katie says
November 20, 2017 at 8:46 amI assume the rosemary and thyme is dry, not fresh?
Sarah Hardy says
November 21, 2017 at 9:11 amYes, that is correct.
Kristen says
December 4, 2017 at 8:20 pmCan’t wait to try this!
Rj says
December 20, 2017 at 12:31 pmTo watch your 50 second video there was a 9 minute car ad. You may want to look in the absorbent amount of ads necessary to watch your videos..
Sarah Hardy says
December 20, 2017 at 2:25 pmI’m sorry about that – you should be able to skip the ad after 5 seconds. I can talk to my ad company and see if there is a problem.
Jody says
December 21, 2017 at 3:39 pmThis is cooking in the oven now and I wanted to share my modification to make it even easier. I cooked two chicken breast in the pressure cooker, then added all the ingredients except broccoli and cheese. Then I used a hand mixed to shred the chicken and mix the ingredients at the same time. So simple and I’m sure it will be tasty!
Tara McLoughlin says
December 22, 2017 at 7:40 amThis looks great! I think I will make it with chicken thighs or a mix of thighs and breasts to add more fat. Thanks for sharing!
Pati says
January 19, 2018 at 5:23 pmThe chicken thighs work great!
Valerie says
January 8, 2018 at 10:56 pmWould subbing the sour cream for mayo be too much mayo? I don’t have any sour cream and want to make this in the morning.
Sarah Hardy says
January 9, 2018 at 10:59 pmThat would still work fine!
Pati says
January 19, 2018 at 5:22 pmThis was delicious, I’ve made it twice! Second time I used chicken thighs cooked with jalapeño pepper and also used the pepper in the cream cheese mixture. Topped it with half pepper jack cheese and mozzarella for a slight bit of heat for our Texas palate!!!!!
Sarah Hardy says
January 20, 2018 at 2:06 pmThat sounds awesome!
Kelly Loykasek says
February 5, 2018 at 11:38 amCan you make this casserole in a crock pot instead of the oven?
Sarah Hardy says
February 5, 2018 at 3:07 pmYes, I would think so, but I rarely use a crockpot, so I do not know how long it would need to cook.
Melissa Berg says
February 16, 2018 at 6:24 pmAMAZING!!! The hubby loved it too! Full of flavor and one serving filled me up completely! I added some spinach and used colby jack shredded cheese…and left out the rosemary and thyme because I didn’t have any and it was delicious! Thank you for sharing!
Mackenzie says
March 28, 2018 at 10:20 pmHas anyone ever assembled this casserole ahead of time and froze it for later? How did it turn out?
Nanci says
February 10, 2019 at 10:07 amWas wondering the same thing. Can you freeze it ?
Sarah Hardy says
February 12, 2019 at 8:59 amYou should be able to freeze this casserole.
Scotia Powell says
May 22, 2018 at 5:56 pmHello. Thanks for the recipe. I used ricotta cheese instead of mayo and leftover chicken thighs. I put the meat and skin in food processor to break it down. I also added mild cheddar cheese. This turned out so delicious. Will make this again. I thought I could add a picture but couldn’t. Thanks again.
Cindy says
June 27, 2018 at 7:19 pmHow many servings are in this dish?
Sarah Hardy says
July 2, 2018 at 11:15 pmI usually get 6 large servings from a 9×13 dish.
Jmac says
July 17, 2018 at 6:03 pmI tried it with chicken and switched it up and tried it with ground beef. Both are amazing!
Great recipe!
Mrose says
July 22, 2018 at 4:27 pmThis is delicious!
Andrea says
September 7, 2018 at 4:02 pmI changed it a little. I made an addition. I added frozen garlic cauliflower rice. I cooked it first according to the package, then added. It was phenomenal. My kids loved it
Robin says
October 8, 2018 at 5:37 amI used boneless skinless thighs when I made this and took it to “game night” with our next door neighbors and everyone loved it. I think it would also be good with some artichoke hearts added. Can’t wait to make it again!
Susan says
March 5, 2019 at 5:00 pmCan you get rid of the ANNOYING ad that sits on top of the screen and doesn’t have any button to close it? I don’t want any recipes emailed to me!
Sarah Hardy says
March 5, 2019 at 10:10 pmHi Susan, I spent time today working on that very thing. I’m sorry there still appears to be a problem. Rest assured I am working on it! 🙂
Janell says
May 29, 2019 at 4:35 pmThis received rave reviews from my family! Very good. Only problem with low-carb casseroles like this is that they do not have the noodles or rice that act as a filler to stretch them for a large family.
