This Keto Chicken Broccoli Casserole is extra cheesy and bursting with goodness. My whole family loves this mixture of creamy, cheesy broccoli and juicy chicken. This casserole is ready in less than 30 minutes!
I have a feeling that one of these days I’m going to share a broccoli recipe and you guys are just going to leave me behind.
I mean, look…I know I share a lot of broccoli recipes, it’s just that they’re SO GOOD. I love broccoli!
Most people think ‘cauliflower’ when they think low carb, but not this girl. I’m all about the little baby trees. 😉
This recipe is a riff on my broccoli cheese casserole that has been reviewed over 400 times with a 4.5 star rating. It’s the best!
Karly’s Tips & Tricks:
Use pre-cut, packaged broccoli florets from the produce section to cut down time!
Bulk it up by adding riced cauliflower to the mixture! Just add in one bag of frozen riced cauliflower and increase the mayo to 1/3 cup and the cheddar to 1 1/2 cups!
In my experience, steaming broccoli in the microwave is just as tasty and so much easier than steaming it on the stove. Follow our method for easy steamed broccoli using the microwave to keep this extra simple.

Chicken – Leftover chicken works great for this recipe, or you can grab a rotisserie chicken from the store. Chop your chicken into chunks or shred it up.
Broccoli – Freshly chopped florets are great but you can also keep it simple and pick up a bag of pre-chopped from the store. See the FAQ’s section below for info on using frozen broccoli.
Cheese & Mayo – This is a creamy and cheesy casserole recipe! We’re adding freshly grated cheddar, grated Parmesan, cream cheese, and mayonnaise. Start with room temperature cream cheese for easy mixing!
Seasoning – We’ll flavor this chicken and broccoli bake with simple seasonings including salt, pepper, and garlic powder. You can add other herbs/spices as you like. Some red pepper flakes would add a bit of heat!
- Family Friendly – The kids love chicken and cheese, which helps sneak the broccoli by.
- Low Carb – This dish is naturally low carb and keto friendly. No funky or hard to find ingredients!
- Easy Peasy – We love to make this recipe using leftover chicken and a bag of broccoli florets. Really cuts down on the prep work!
Substitutions & Variations:
Make this casserole your own by swapping ingredients or adding to it. Casseroles are great for customizing! Here are some ways you can modify this chicken broccoli casserole:
- Protein: Swap the leftover chicken with some leftover turkey or use ground chicken, turkey, pork, or beef! Toss in some crispy fried bacon for a little extra protein.
- Greek Yogurt: It’s a great substitute for the mayonnaise.
- Cheese: You can use any combination of cheese you want! Swap out the cheddar and Parmesan or mix in others like Colby, Monterey Jack, Swiss, etc.
- Veggies: The broccoli could be swapped for cauliflower, or you could just use both. You can also add other vegetables like onion, bell pepper, or even green beans in this chicken and broccoli casserole.
How To Steam Broccoli In The Microwave:
We start this recipe with a head of broccoli and that gets microwaved with a bit of water just to soften it up a bit.
The microwave steams the broccoli which gives it a head start on the cooking process. I just add the broccoli and 2 tablespoons of water to a large bowl, cover tightly with plastic wrap, and microwave for 2 minutes.
Let this stand for 2 minutes before carefully removing the plastic wrap and draining the liquid. So easy!
How To Make Chicken Broccoli Cheese Casserole:
- Combine – To prepare the casserole you’ll just dump in the rest of the ingredients with the steamed broccoli. Stir all of that together until it’s combined and then spread it into a 9×13 baking dish.
- Top & Bake: Sprinkle a bit of shredded Parmesan over the top to add a little salty crunch factor. This bakes up in just 15 minutes.
- Serve – We like to serve this keto chicken broccoli casserole with something a little lighter on the side, like my keto coleslaw. Of course, my keto cheddar bay biscuits make a great addition to this meal too!
FAQ’s:
I like to start with fresh but frozen broccoli will also work well in this recipe though it may add a bit more moisture to the casserole than it would if you had started with fresh florets.
The already cooked kind! Leftover chicken, a rotisserie chicken from the store, frozen cooked chicken. This recipe is all about keeping it simple!
You can keep any leftovers stored in the fridge in an airtight container for up to about 3 days depending on the freshness of the ingredients you used such as the chicken.
Yep! Most casserole recipes are freezer friendly and this one is too. Make sure it is stored well in a freezer safe container and it should last for up to a few months. It can be reheated in the oven after thawing.

Karly Campbell says
Love to hear that! Thanks, Mary!
Judith says
Just prepared this I added some mustard and cream as well can’t wait to try
Karly Campbell says
Hope you enjoyed! 🙂
Charlize says
This came out amazing! I am truly a terrible cook but this was so easy! Do you think I can add boiled pasta to the mix before baking for a non- Keto dish?
Karly Campbell says
Yep, I think that would work fine. You might want more of the cheese mixture if you’re coating pasta too, though.
Meg says
Do you think using sour cream instead of mayo would be good?
Karly Campbell says
Probably, though I haven’t tried it.
Adrianna says
Hi!! Just wondering where the grams of sugar come from?
Karly Campbell says
The broccoli, cheese, and spices all have moderate amounts of sugar in them. No added sugars in the recipe, but the sugar from veggies, cheese, and spices do add up. 🙂
Walter says
Hi, did not see a place to post a picture. How do I do that or maybe it is not available?
Karly Campbell says
Hi Walter! You’re not able to post a picture here, but you can join the facebook group and share there if you like. https://www.facebook.com/groups/1575661529219359
sherry L ottoson says
Good but a little dry.
Kate says
The video shows when she adds the chicken & it’s clear to see its precooked
Paulet says
Hi! The recipe directions say to use an 8×8 pan, but in the dialogue part above it you say to stir it together and mix in a 9×13. Will either one work? I’m concerned it won’t be enough food for a family of four.
Karly Campbell says
Hi Paulet! Sorry about the confusion – the recipe should be baked in a 9×13. I’ll update the recipe card now. 🙂
Kyle says
This came out really good but what is the serving size? Is it 1cup?
Karly Campbell says
Hi Kyle! I didn’t measure by volume, just divided it into 4 equal servings.
Wil says
It was delicious! I mixed the chicken in with the cream cheese and Broccoli
Yvonne says
I watched the video to prepare everything; going to try tonight!
Karly Campbell says
Hope you love it!
Linda Kuball says
Can you use frozen broccoli
Karly Campbell says
Yes, I think so. It may end up more watery than with fresh though.
Walter says
Just drain in a strainer for 5-10 minutes.
Jan Gage says
Hi Karly, I’m just a little unsure when/where to add the chicken? Thanks much…….Jan
Karly Campbell says
Sorry about that, Jan! It gets mixed with the broccoli and cheese mixture. 🙂
Janet Stout says
Love your recipes. The recipe didn’t tell me when to add the chicken so I did just before putting in oven. Did the baking dish need to be greased?
Karly Campbell says
Sorry about that, Janet! I toss in the chicken and mix it up with the broccoli and cheese mixture. I don’t grease the dish, but it won’t hurt anything if you do. 🙂
Teresa Matney says
Looks wonderful, going to try it soon. On the KETO diet and needed some ideas . Like what I’m seeing. Blood sugar levels are already improving.
Paula says
At what point do you add the chicken???
Karly Campbell says
Sorry about that, Paula! It gets mixed in when you combine the broccoli and cheese mixture.
ida says
why is it I can only print out a few of your reciepes
Karly Campbell says
Hi Ida! Can you tell me what issues you’re having? The print button seems to be working fine for me.
Sharon Reische says
You need to re-write the instructions. You never tell the cook when or where to add the chicken. Also, in the notes, when referring to “frozen Chicken”, you just say to thaw the chicken first, nothing about how to cook it.
Karly Campbell says
Sorry about that, Sharon! The chicken gets added along with the broccoli to the cream cheese mixture. In the notes, I’m referring to the pre-cooked chicken that you purchase frozen from the store.
