The whole family will love this cheesy Keto Shredded Chicken and Broccoli Casserole! Made with simple ingredients, less than 40 minutes, and 2 different ways to make it.

Colder temperatures always scream comfort food and casseroles to me. Especially healthier casseroles like my low-carb Chile Relleno Casserole, Baked Zucchini Noodle Spaghetti, or Keto Chicken Divan Casserole! What’s so great about all of these casseroles is that you’d never believe they were healthy.
As a nutritionist, I like to take comfort foods and make lighter variations. All great flavor (hello healthy fats and cheesy goodness), but with some veggies too. Casseroles also make the best family dinners on busy weeknights. You can make it in advance and immediately put it in the oven. Or do some meal prep on the weekends to get everything ready with minimal prep!
In this recipe, you will definitely like the white garlic cheddar sauce. It pairs perfectly with fiber-rich broccoli! I’m also giving you a few options for topping dinner with cauliflower rice (or plain rice if you prefer a more kid-friendly option).

Make this Keto-Friendly Chicken Broccoli Casserole
Here are the ingredients you will need:
- Broccoli
- Pre-cooked chicken
- Butter
- Minced garlic
- Cream cheese
- Half and half
- Dijon mustard
- White cheddar
- Black pepper and sea salt
- Rice or cauliflower rice (optional)
We start by boiling broccoli florets. We want it to be al dente, slightly softened, but not too much! It will only take about 3 minutes. Place in a 9×13 casserole dish and toss with the shredded chicken, and cauliflower rice (or rice if using).
Meanwhile, make your cheesy sauce in a small saucepan. Melt the butter, then add the garlic and sauté for 1-2 minutes. Add cream cheese, half and half, dijon mustard and salt. Whisk the sauce until smooth and heat. Pour over broccoli and chicken.



Transfer the casserole to the oven and bake for 20 – 25 minutes, or until bubbly and lightly browned. Serve hot!
