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. ๐Ÿ˜‰ 

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!

  • 20 ounces fresh broccoli florets

  • 1 teaspoon garlic powder
  • ½ teaspoon ground black pepper
  • ¼ teaspoon salt
  • 2 cups cooked, chopped chicken
  • ¼ cup grated Parmesan


  1. Preheat oven to 350 degrees.
  2. Add the broccoli to a large microwave safe bowl along with 2 tablespoons of water. Cover tightly with plastic wrap and microwave for 2 minutes. Let sit, covered, for 2 minutes.
  3. Carefully remove the plastic wrap and drain the liquid.
  4. Add the cream cheese, mayonnaise, cheddar, garlic powder, salt, and pepper to a small bowl and mix well to combine.
  5. Stir the cream cheese mixture and chicken into the steamed broccoli until well combined.

Rotisserie chicken, leftover cooked chicken, or the frozen chunks of grilled chicken you can buy at the store all work well in this recipe. If you using frozen chicken, thaw before adding to the casserole.

  1. Linda Vermette

    I had no problem with adding any of the items I just mixed them all together and put them in the oven and wow it was great

  2. I just tried your recipe and oh my goodness! Delicious!!! I feel like I am a terrible cook but appreciate good food. I had great success with your recipe. Thank you!!!

  3. 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?

    1. Karly Campbell

      Yep, I think that would work fine. You might want more of the cheese mixture if you’re coating pasta too, though.

    1. Karly Campbell

      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. ๐Ÿ™‚

  4. Hi, did not see a place to post a picture. How do I do that or maybe it is not available?

  5. 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.

    1. Karly Campbell

      Hi Paulet! Sorry about the confusion – the recipe should be baked in a 9×13. I’ll update the recipe card now. ๐Ÿ™‚

    1. Karly Campbell

      Hi Kyle! I didn’t measure by volume, just divided it into 4 equal servings.

  6. Hi Karly, Iโ€™m just a little unsure when/where to add the chicken? Thanks much…….Jan

    1. Karly Campbell

      Sorry about that, Jan! It gets mixed with the broccoli and cheese mixture. ๐Ÿ™‚

  7. Janet Stout

    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?

    1. Karly Campbell

      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. ๐Ÿ™‚

  8. Teresa Matney

    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.

    1. Karly Campbell

      Sorry about that, Paula! It gets mixed in when you combine the broccoli and cheese mixture.

    1. Karly Campbell

      Hi Ida! Can you tell me what issues you’re having? The print button seems to be working fine for me.

  9. Sharon Reische

    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.

    1. Karly Campbell

      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.
