The slow cooker does all the heavy lifting, so you can toss in your ingredients and come back hours later to a warm and satisfying dinner.

Why You’ll Love This Keto Cheesy Crockpot Chicken and Broccoli Casserole

This casserole brings together everything you want in a keto meal: high protein, low carb, big flavor, and minimal cleanup. The slow cooker method means tender, juicy chicken every time, while the cheesy sauce coats every bite in creamy goodness. Plus, it reheats like a dream, so leftovers are never boring. It’s family-friendly and great for anyone looking to cut carbs without sacrificing comfort food classics.

Can I Use Frozen Broccoli in This Casserole?

Absolutely. Frozen broccoli works just as well as fresh, especially since it softens beautifully in the slow cooker. Just be sure to add it closer to the end of the cooking time to keep it from turning mushy. If you want more bite, fresh broccoli florets are your best bet, but frozen is a convenient and budget-friendly option.

Ingredients for the Keto Cheesy Crockpot Chicken and Broccoli Casserole

This recipe keeps things simple while delivering on flavor. Here’s what you’ll need:

Chicken breasts are the protein base of this dish. Boneless and skinless is easiest, and they shred perfectly after slow cooking.

Broccoli florets bring fiber and nutrients to the mix. They add color, crunch, and balance out the richness of the cheese.

Cream cheese creates the creamy texture that makes this casserole irresistibly smooth.

Shredded cheddar cheese adds that familiar cheesy punch. Sharp cheddar works best for bold flavor.

Chicken broth keeps everything moist and adds savory depth.

Garlic powder adds just the right amount of kick without overpowering the other flavors.

Salt and pepper are simple but essential for seasoning throughout the dish.

Heavy cream helps blend everything together into a luscious sauce.

How To Make the Keto Cheesy Crockpot Chicken and Broccoli Casserole

Step 1: Prepare Your Ingredients

Place the chicken breasts in the bottom of the crockpot. Season them with salt, pepper, and garlic powder. Pour in the chicken broth to keep them moist as they cook.

Step 2: Let It Cook

Cover and cook on low for 4-5 hours, or until the chicken is fork-tender. You can also cook on high for 2-3 hours if you’re short on time.

Step 3: Shred the Chicken

Once cooked, remove the chicken and shred it using two forks. Add it back into the crockpot and stir to combine with the juices.

Step 4: Add the Cheesy Goodness

Stir in the cream cheese, heavy cream, and shredded cheddar. Let everything melt and blend together, stirring occasionally.

Step 5: Add the Broccoli

Toss in your broccoli florets and cover again. Let it cook for another 20-30 minutes, until the broccoli is tender but still has a bite.

Step 6: Serve It Up

Give it one final stir, and your casserole is ready to dish out. The sauce should be creamy, cheesy, and clinging to every bite.
