Low Carb Chicken Casserole: Ultimate Keto Potluck Dish

Do you ever just want a big steaming bowl of comfort food?  You know, something that tastes good, but also just makes you feel good inside. 

Food is so much about endorphins for some of us, and this recipe is one that is perfect for my keto lifestyle but also has that feel good sensation I sometimes need.

I confess this probably shows up on my menu more often than any other recipe. All because it is just so delicious and comforting.

Do I have to use broccoli in this casserole?

Every child will say that they hate broccoli. Okay, not every kid, but many.  Broccoli just gets a bad reputation, but it really is amazing.

I realize that not everyone feels that way about it though, so I have to answer this question for you. 

No. You do not have to use broccoli in this recipe.  You do, however need a vegetable option that is low in carbs. 

Below are a few options you could use instead of broccoli. 

  • Cauliflower
  • Brussels sprouts
  • Asparagus
  • Green beans
  • Artichoke Hearts

You could also mix in greens like spinach, kale, or collards, but they wouldn’t give the same texture and snap you want with a heartier green vegetable. 

For a completely new flavor give this Tex-Mex cabbage beef skillet recipe, keto jalapeno popper casserole recipe a try or how about one of these keto freezer meals!

What I serve with this low carb chicken casserole with broccoli

Typically when you think of the word casserole, you think of an all in one meal.  When you are low-carb or keto, that isn’t always the case.

Or, if you live in a home with keto and non-keto individuals, you’ll need to provide something else with this casserole. 

For those who can bypass the temptation, pasta or rice is a great way to make this a full meal. 

If you just can’t overlook the pasta, then grab some zoodles or spaghetti squash to serve this over.  It gives you the pasta feel with zero guilt. 

Other keto options are this low carb potato salad made with cauliflower, low carb cheddar biscuits, or this truly amazing grain free bread

The key is to make sure you are satisfied at meal times so you don’t fall off plan due to temptations. 

The fats in this meal help me stay full, but when in doubt, a slice of avocado on top with some grain free bread makes a very satisfying meal.

My favorite cheese blends for the keto diet

I love cheese. There, I said it. Cheese is just so good!  Thankfully, it is a staple on low carb and keto diets. In this recipe, I use cheddar, but there are some great ideas for other cheeses you could mix into this recipe. 

  • Cheddar – Mild or a mix of sharp and mild 
  • Pepper Jack 
  • Mozzarella 
  • Colby Jack
  • Gouda
  • Fontina
  • Gruyere
  • Swiss

Note: Avoid buying already shredded cheese if you are following your macros closely. It often has fillers to keep it from sticking together that add unwanted carbohydrates. This isn’t important for everyone, but for some, every little bit counts.

Tips for keeping this keto chicken and broccoli from sticking to your pan

One of my least favorite things to do is stand over the sink scrubbing gunk out of the bottom of a casserole dish.  The problem is, I kind of like those sort of burnt on pieces of cheese in casseroles. 

My solution? Don’t fear the butter.  Seriously, just slather butter all over that casserole dish before you pour in the chicken, veggies, and cheese mixture.  While you still get your somewhat crispy edges, they will slide right off with no struggle. 

If all else fails, assign someone else dishes duty and go relax while they struggle with the stuck on food.

      1. This was really good. I doubled it and used Velveta for part of cheese, it was to much cheese. I will use less next time.

  1. Now that I am watching my sugar and carbs this is a great weeknight meal that will make a great breakfast of leftovers the next morning. If there are any;)
