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.
