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!

How to: 

We love this keto chicken and broccoli casserole for a few reasons:

  1. It’s extra cheesy!
  2. It’s perfect for keto!
  3. It’s QUICK and EASY!

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.

KEEP IT SIMPLE: Buy a bag of already chopped broccoli florets! 

The microwave steams the broccoli just a bit to give 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!

Next, you’ll just dump in the rest of the ingredients! 

You’ll need leftover chicken, cream cheese, mayo, cheddar, garlic powder, salt, and pepper. 

PRO TIP: If you don’t have leftover chicken, you can grab a rotisserie chicken from the store or use a bag of the pre-cooked, frozen chunks of grilled chicken. Just thaw them in the microwave before using.

Stir all of that together until it’s combined and then spread it into a 9×13 baking dish.

Sprinkle a bit of shredded Parmesan over the top to add a little salty crunch factor. 

This bakes up in just 15 minutes.

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!

  1. Revise your recipe to mention “cooked chicken” at every instance otherwise it is easily missed. Like I missed it. Raw chicken and baked broccoli with cheese is not awesome.

      Sorry to hear that you missed it. It’s clearly stated to use cooked chicken in both the post, the recipe, and the notes. Hope you give it a try with cooked chicken…it’s so good! 🙂

    Sort of left field but I was in a hurry and out this recipe in a pressure cooker and it was great! Added a bit of bacon and 1.5 tbsp of heavy cream. Somewhere between a stew and soup and was really really good.
