How To Make the Keto Cheesy Crockpot Chicken and Broccoli Casserole

Step 1: Prep the Chicken

Place your raw chicken breasts in the bottom of your slow cooker. Season with garlic powder, onion powder, salt, and pepper.

Step 2: Add Creamy Ingredients

Cube the cream cheese and scatter it over the chicken. Pour the heavy cream evenly across the top.

Step 3: Cook Low and Slow

Cover and cook on low for 4-6 hours, or until the chicken is cooked through and fork-tender.

Step 4: Shred and Stir

Remove the chicken and shred with two forks. Stir it back into the creamy mixture until evenly combined.

Step 5: Add Broccoli

Add in broccoli florets and half of the shredded cheeses. Stir well, then smooth the top.

Step 6: Top and Melt

Sprinkle the remaining cheese on top. Cover and cook for an additional 20-30 minutes until the broccoli is tender and the cheese is melted and bubbly.
