Craving a cozy, low-carb dinner that basically cooks itself? This Keto Cheesy Crockpot Chicken and Broccoli Casserole is everything you want in a weeknight meal—rich, creamy, packed with flavor, and best of all, keto-friendly. It takes comfort food to a whole new level while keeping your macros in check.

Whether you’re meal-prepping or feeding a family, this casserole brings together tender shredded chicken, vibrant broccoli florets, and a cheesy sauce that melts into every bite. And thanks to your slow cooker, it’s all done with minimal fuss.

Preparation Phase & Tools to Use

Making this casserole is a breeze, especially with the right tools at hand:

Crockpot/Slow Cooker: This is the heart of the recipe. It ensures the chicken becomes fall-apart tender while letting the flavors meld perfectly over time.
Cheese Grater: Freshly grated cheese melts better and adds more creaminess than pre-shredded bags.
Mixing Bowls: For prepping your cheese mixture and tossing ingredients before adding to the crockpot.
Tongs or Forks: Handy for shredding the cooked chicken before mixing it back in.
Measuring Cups & Spoons: Essential to keep your keto-friendly portions accurate, especially for ingredients like cream cheese and cheddar.

Having everything ready before you start helps streamline the process and keeps your kitchen mess-free.

Ingredients for the Keto Cheesy Crockpot Chicken and Broccoli Casserole

Each ingredient here is carefully chosen to deliver flavor and keep things keto.

Chicken Breasts: Lean protein base of the dish. They absorb the cheesy sauce and fall apart beautifully after slow cooking.
Broccoli Florets: Adds crunch, fiber, and vibrant color. Also keeps the casserole feeling fresh.
Cream Cheese: Gives that rich, creamy texture while keeping carbs low.
Heavy Cream: Adds silkiness to the sauce and enhances the richness without needing a roux.
Shredded Cheddar Cheese: Melts into the casserole and creates that signature golden crust on top.
Garlic Powder & Onion Powder: Essential low-carb seasoning that infuses savory flavor.
Salt & Pepper: For seasoning and balance.
Paprika (optional): Adds a mild kick and a touch of color to the finished dish.

How To Make the Keto Cheesy Crockpot Chicken and Broccoli Casserole

Step 1: Prep and Layer

Place raw chicken breasts at the bottom of the crockpot. Season with salt, pepper, garlic powder, and onion powder.

Step 2: Creamy Blend

In a separate bowl, whisk together the softened cream cheese and heavy cream until smooth. Pour this over the chicken.

Step 3: Add the Broccoli

Scatter the broccoli florets evenly on top. Don’t stir—just let the steam soften them gently as the casserole cooks.

Step 4: Cook Low and Slow

Set your crockpot on LOW for 5 to 6 hours or HIGH for about 3 hours. The chicken should be fork-tender and the cream mixture well blended.

Step 5: Shred and Combine

Once cooked, remove the chicken, shred it using two forks, then mix it back into the crockpot along with the broccoli and sauce.

Step 6: Cheese Finish

Top with shredded cheddar cheese, cover again, and let sit for another 10–15 minutes until melted. For a bubbly finish, you can transfer to an oven-safe dish and broil for a few minutes.

Serving and Storing Your Keto Chicken and Broccoli Casserole

This casserole is best served warm, straight from the crockpot or after a quick broil for a crispy cheese top. Pair it with a fresh side salad or cauliflower rice for a full keto meal. Garnishing with fresh parsley adds brightness and contrast.

To store leftovers, let the casserole cool completely before transferring to an airtight container. Refrigerate for up to 4 days. It reheats well in the microwave or oven. For freezing, portion it into meal-sized containers and store for up to 2 months.

Frequently Asked Questions

Can I use frozen broccoli?

Yes, but thaw it first and pat it dry. Otherwise, it may water down the sauce.

Can I substitute chicken thighs?

Absolutely. Thighs are juicy and flavorful, and they also work great in this recipe.

How do I make this spicier?

Add a pinch of red pepper flakes or stir in a spoonful of your favorite keto-friendly hot sauce.

What can I use instead of cream cheese?

Try mascarpone or a keto-friendly ricotta. Just be aware the texture will be a bit different.

Can I bake this in the oven instead of using a crockpot?

Yes! Combine everything in a baking dish and bake at 375°F for 25-30 minutes, or until the chicken is fully cooked and cheese is bubbling.
