How to Make Keto Chicken & Broccoli Casserole
Preheat oven to 375F.
Add the cubes of parmesan to into the bowl of a food processor and pulse until coarsely grated.
Add all the remaining ingredients except the chicken, broccoli and mozzarella cheese and mix until well combined and thickened, to make the sauce.
In a separate bowl, add in the chicken, broccoli and mozzarella cheese (reserving 1 cup for the topping).
Spoon the sauce over the top and mix until everything is well coated.
The sauce will be very thick, so you might think you won't have enough liquid, but trust me it's plenty! Transfer to a greased 9 X 12 casserole dish. Add the reserved cup of mozzarella cheese over the top.
Bake for 40-50 minutes or until the broccoli is tender and the cheese is golden.
Allow to cool slightly before cutting into and serving.
Tips for Low Carb Chicken Casserole
After a long day, most everyone struggles to find a quick and healthy weeknight meal the whole family will love. This Keto broccoli and chicken casserole is already quick and easy but here are some more time saving tips to make it even quicker:
- You can use rotisserie chicken and shred it. Be sure to check out the ingredients on the label because some brands have added sugars and preservatives that those on Keto will want to avoid.
- Though fresh is preferred, you can use frozen raw broccoli in this casserole. Don't cook it beforehand, just mix it in frozen with the other ingredients before baking.
- Another broccoli tip is, instead of chopping a head of broccoli up into florets, you can buy a package of fresh pre-cut florets
- It's recommended that you shred your own cheese because pre-shredded cheese has anti-caking ingredients. But let's face it, sometimes you just don't have the time, so feel free to use pre-shredded. It won't change the flavor one bit.
Is Broccoli Keto?
Absolutely! Broccoli is a cruciferous veggie, so it’s very nutrient-dense and high in fiber. And, the great news its low in carbs. For one whole cup there's 6 grabs of carbs with almost half of that being fiber, making the net carbs approximately 3.5 per cup.

Another wonderful aspect about broccoli on Keto is that there're so may ways to add healthy fats to it. Whether it's in a creamy low carb side dish or steamed with grass-fed butter, or even in a casserole like this Keto chicken casserole that has both yummy cheeses and heavy cream, the possibilities are endless. It's truly the quintessential Keto veggie!

Can you sub the mascarpone cheese?
Keto Cooking Christian
Sure! You can use cream cheese in its place.
Jennifer Colvin
I love Rotel, would Rotel go well in this??
Keto Cooking Christian
I have never used rotel tomatoes in this recipe but it sounds good!
Judy
Cheddar cheese is mentioned in the second paragraph of your blog, but there isn't any cheddar cheese mentioned in the recipe. I think I would have liked it better with some cheddar cheese.
Brandy
So funny story. I buy block cheese and it wasn’t until I was shredding the “mozzarella” that I realized it was white sharp cheddar! 🤦🏻♀️ It was gumming up in my kitchen aid attachment and then I realized. Long story shorter, my husband says “just use it”. Which we did. It was a little rich but really good. In case anyone wants to try it with cheddar 😂
Keto Cooking Christian
Oh that's awesome! Well I'm glad it worked out and thanks so much for letting us know! 🙂
Nancy Markle
Love all your recipes and especially Scriptures!!❤️

How many servings in this recipe? I made this yesterday it’s amazing! I did double the meat however and it came out very hearty. I estimated 6 servings.
Keto Cooking Christian
There are 8 servings in this casserole, and it's pretty filling. Glad you enjoyed it 🙂
Jody
How do these casseroles freeze when there is mayonnaise and cheese sauce and or sour cream? I’d like to portion out separate servings to freeze as it is only my husband and I...but not sure if some of these casseroles will separate when there is dairy involved after freezing. Have you done this? Frozen your portioned out leftovers? Thanks in advance.
Keto Cooking Christian
Hi Jody,
Yes, I freeze almost all my casseroles, so I have a few portions on hand for later. They freeze, thaw and reheat perfectly! And honestly, some of them taste even better after they are reheated. I hope that helps!

Absolutely delicious!! My family loved this! The golden brown top is the best part
Keto Cooking Christian
Hi Elizabeth,
Glad to hear your family loved it! And I agree, that golden melted cheese is really the best part!
Joyce
I made this last night with chicken thighs that were already deboned and skinned. It's what my husband bought by mistake. I boiled them in chicken bone broth for about an hour and shredded them for the recipe. It was OUTSTANDING. We will be using this recipe over and over. It's outrageously delicious. Didn't change anything in the recipe. It's perfect.
Keto Cooking Christian
Hi Joyce, it sounds like a very happy mistake! Using chicken thighs is even better for Keto, due to the higher fat content, not to mention they are more tender! I'm so glad you enjoyed it, thanks for taking the time to let me know 🙂

16 oz chicken by weight or volume?
