If you plan to freeze do you want to bake it before freezing or can you put it together and freeze?
Hi Tierney, yes, you can bake it before freezing. Hope that helps.
I have made lots of chicken and broccoli casseroles. This one is the best we have ever made. Will make this again. Thank you
Hi Tammy, thank you, so glad you like it.
Love this dish, my wife done it so good, with burnt cheese topping yummy…
But it seems we used wrong type of cream which became like milk is that right, but the taste is just perfect
Thanks for the recipe
Hi Ali,
It may have been the wrong type of cream, we haven’t had this issue but we likely have a different cream manufacturer than you so that may be a factor. Maybe try less cream and more cheese. Glad you liked the recipe.
This was so yummy!! I loved it and it will be a regular dish in our home now. How do you think it would turn out if you used ground sausage instead of chicken? I love it as is just always have lots of sausage on hand
Hi Jenny, I think the Sausaugae would work out ok if you maybe made meatballs out of it or something. But don’t be afraid to experiment, if you do let us know how you go. Thanks for your kind words.
Can I make this with frozen broccoli? I also only have unsweetened vanilla almond milk. Will this make a huge difference?
Hi Suzanne, yes you certainly can use frozen broccoli.
Wow what flavor everyone loved this casserole, Thank you
So glad everyone loved it Lydia. Thank you so much for your nice comment.
Question: is it ok to make it ahead and bake it tomorrow?
Hi Fatima,
Yes, no problem. Hope you enjoy it.
Excellent! I made this for a potluck and got rave reviews. What a great comfort dish for the cold weather coming!
Hi Elaine, thank you so much for the kind words. So glad you liked it.
My boyfriend and I like this recipe better than a non-keto recipe!! Easy to prepare and a household favorite!
Thank you for your kind words Emily glad you like it.
This is a really good dish! The sauce could also be used on its own as an Alfredo sauce for rzoodles. Thanks for the recipe!
This is delicious! I will definitely make this one of my favorite recipes!
Hi,
How do you think substituting coconut cream for the heavy cream would impact the taste?
Hi Katie,
It would just add a bit of a coconut flavour – if you like coconut, why not give it a try!
This recipe was SO GOOD! Even my 3 year old who never eats broccoli enjoyed it and ate his entire serving. Definitely will make it again. I was wondering if this casserole could be mixed together and then frozen?
Hi Karissa,
I’m so glad to hear we pass the toddler test! My parents called broccoli “little trees” when I was a kid and I LOVED to be the giant eating the trees haha.
I’m not sure how a frozen unbaked casserole would turn out as I haven’t tried it, but a baked one can be frozen and reheated with no problems at all.
Delicious! I made this with with meatless chik’n strips instead of rotisserie since my wife is vegetarian, and it worked great!
Is there a substitute for the unsweened Almond milk? Can I use regular milk or evaporated milk?
Hi Jean,
You can substitute the almond milk for more cream, or any milk of your choice. Just note that using cow’s milk will increase the carb count.
Super sad! This smelled so lovely but its so watery! Followed the recipe 100% and its really watery. Was hoping for a more creamy texture.
Hi Sarah,
I’m sorry that the recipe didn’t work for you, it sounds like you didn’t drain your broccoli well enough? The sauce does come out thick and creamy but if the broccoli isn’t drained well, it will water down the sauce.
The first time I made it I had the same result. I tried again two weeks later and it turns out I hadn’t drained the broccoli well enough. Give it another go but drain everything a little longer. Good luck! My second batch turned out creamy.
Agreed! I poured the veggies in a strainer with small holes and used a spoon to press the excess moisture out of the veggies before mixing in the sauce. It was super creamy and not at all watery. I even added riced cauliflower to mine which has tons of moisture and ended up with a thick creamy bake. Try it again, soooo worth it!
This was DELICIOUS! I never leave reviews but had to say this is my favorite version of broccoli chicken casserole I’ve ever had, keto or not. Also it’s super filling – 1 serving left me stuffed!
I’m so glad you enjoyed it, Mel! Thanks for popping back to leave a comment 🙂
This was AMAZING! I topped it off with bacon bits.
This was SO good! Loved it made exactly as recipe is listed.
I made this tonight by the recipe except had to sub dried basil for fresh. It was great. Not the same old cream of something sauce. Will definitely make this again.
Love finding a delicious recipe you can’t wait to make again! I added a generous helping of curry powder as another reviewer suggested and the final product was a tastier, healthier Chicken Divan! We made ours with diced chicken breast instead of rotisserie chicken & served over a mix of quinoa and rice the first night. We finished the leftovers by themselves (no sides) the very next day. So yummy!
The addition of curry powder is sounding really good! I will have to try it soon.
I’m so glad you enjoyed it!
Very honestly, I rarely make a dish according to a strict recipe…so with this casserole I, of course, did some embellishments by adding sauted onions & mushrooms and diced roasted green chili…AWESOME!!! Added a little more character and cut the richness from the sauce. I know this added a few more carbs, but my husband loved it!!!
Thanx for a great template to start from!!!
Cheers!!!
Those additions sound delicious Penny! I look forward to hearing about other changes that you make from the template 🙂
This was great. Saved it to my carb manager so I don’t lose it. Thanks!
this is the BEST recipe! I always add more garlic, bc I love the garlic. But I have made this multiple times. Sometimes if I have cauliflower and or onions I will add ! Thank you for sharing this!
I have made this 5-6 times It’s that good. My mom used to make a broccoli chicken casserole with cream of chicken soup and mayonnaise for the filling and breadcrumbs added with the cheese on top and this comes pretty darn close to it while being keto friendly! Fantastic recipe. Thank you!!
Thank you for your kind words, Mel!
LOVELOVELOVE this casserole! Made it exactly as written. It also freezes well, I made it and froze leftovers, had that last night. THANK YOU, GERRI!
Easy to make. A winner, every time!
The last time I made this I added 1T curry powder and topped with cilantro,to the recipe, minus basil. Delicious!!!
Sounds delicious Jackie!!
This is delicious!! My husband and I love it…thanks for sharing!! A must try for those who haven’t.
Just made this recipe. Made it like it was listed except for the basil (I didn’t have any). It was so quick and easy to make. And it was delicious! Loved the sauce! Will definitely make again!
I made this tonight and it was fantastic. I have a similar recipe however it called for canned cream of chicken and mayonnaise. I loved making the cream sauce for this knowing everything that was going in it. My recipe also called for bread crumbs which obviously I am not eating. This was so rich and filling and bread crumbs were not missed at all! Very good and will definitely make again!
Absolutely tasty! Very flavorful and extremely filling! I added mushrooms just because I needed to use them but other than that, this was perfect!
This is absolutely Delish.I made exactly as recipe stated to do.
I will definitely be making again.
A big hit! I personally would have used half of the Dijon mustard, but I’m not a huge fan of it anyway. Definitely a keeper! Thanks!!
My family loved this recipe. I didn’t have fresh basil so I used dried. We will definitely make this again.
Can you please tell me what application you used to calculate the nutritional information? I’m getting much higher numbers – particularly net carbs of 15 – using mine!
Hi Lorrie,
We use a feature that is built-in as part of the recipe card. I would recommend checking each ingredient as some apps rely on users entering data, which is not always accurate.
I forgot to rate it 5 stars, see above or below?
This was amazing, everyone in my family loved it! I did make a few alterations out of necessity cause it’s what I had on hand:
1. Used 1 C Heavy Whipping Cream (no almond milk)
2. Used only 4 oz of cream cheese, that’s all I had
3. used 6 chicken breasts (probably over 3lbs) that I cooked and cubed before putting it in the oven.
4. Used frozen broccoli, sauteed in oil and seasoned ahead of putting in the casserole.
5. Added onion powder and extra salt/pepper to taste
6. Omitted basil
7. Added red pepper flakes, cause we like it spicy!
8. Used a combination of cheeses and mixed it into the casserole instead of just putting it on top.
My husband and teenage son raved about this dish, thank you so much! I’ll be back to try some of your other keto recipes for sure!
I’m so glad you and your family enjoyed it Holly! Thanks for stopping by 🙂
Great recipe. I used all heavy cream, topped with crushed pork rinds for a crispy topping. Really good comfort food!
This reminds me of my Chicken Divan, but creamier & without the rice. However, I made regular rice for the kids and riced cauliflower for myself with some Tabasco… Y.U.M!!!
This is perfect to take to someone who needs a meal cooked for them. Huge hit!
This was really tasty, but was the sauce suppose to thicken, pretty watery
Hi Debbie,
The sauce shouldn’t be watery, you might need to drain your broccoli a bit more next time.
Love this recipe I too add just all heavy cream it’s delicious!
YUMMY!!! It was very delicious and the whole family loved it!! So, it gets 5 stars!!!!!!
Excellent tasting & very filling. The only thing I didn’t did was the basil. Maybe next time.
That was amazing. Absolutely delicious!!!!
AHHHMAZING ENTIRE FAMILY LOVED IT
Muito bom adorei a receita!
Obrigado Maria!
Great recipe with simple ingredients! I made some extra sauce and added in a head of cauliflower. My husband loved it!
Glad you enjoyed it Annette. Thanks for stopping by!
Great recipe! I left out almond milk and basil, added cup of cauliflower rice and added a cup more cheese. Yummy!
Soooo good! Full disclosure… I didn’t have Almond Milk so I just added more heavy cream! Delicious!
great and easy to prepare
