Step-by-Step Instructions for Keto Cheesy Crockpot Chicken and Broccoli Casserole

Ingredient Overview

Before starting, ensure you have the following key ingredients ready. Quality matters, especially for keto dishes, where each component contributes significantly to flavor and macros.

• Chicken: Boneless, skinless chicken breasts or thighs (thighs add more fat and tenderness, breasts are leaner)

• Broccoli: Fresh broccoli florets for best texture

• Cheese: Sharp cheddar and cream cheese for richness and meltability

• Cream: Heavy cream to create a luscious sauce

• Seasonings: Garlic powder, onion powder, salt, pepper, and optional herbs or spices

• Additional: Chicken broth or stock to keep the casserole moist and flavorful

Step 1: Prepare the Chicken

1. Trim any excess fat from the chicken breasts or thighs. If using breasts, consider pounding them to an even thickness for more uniform cooking.

2. Season both sides generously with salt, pepper, garlic powder, and onion powder.

3. Optionally, lightly brown the chicken in a skillet with a bit of olive oil or butter for added flavor and color. This step is optional but adds depth.

Tip: Browning chicken before slow cooking is optional but recommended if you want more complex flavor. If short on time, you can skip directly to the crockpot.

Step 2: Prepare the Broccoli

1. Wash the broccoli thoroughly and cut into bite-sized florets.

2. For even cooking, avoid cutting pieces too large or too small.

3. You can blanch the broccoli in boiling water for 1-2 minutes to soften slightly if desired, but this is optional since the crockpot will cook it thoroughly.

Tip: Blanching helps prevent the broccoli from becoming too mushy in the slow cooker.

Step 3: Mix the Creamy Cheese Sauce

1. In a medium mixing bowl, combine:

   • 8 oz cream cheese, softened

   • 1 cup shredded sharp cheddar cheese

   • ½ cup heavy cream

   • ½ cup chicken broth

2. Whisk together until smooth and creamy.

3. Add additional seasonings such as garlic powder, onion powder, salt, pepper, or smoked paprika to taste.

Pro Tip: Use full-fat dairy products for the best keto macros and a rich mouthfeel.

Step 4: Assemble the Casserole in the Crockpot

1. Spray the inside of your crockpot with non-stick cooking spray or lightly grease with butter or olive oil.

2. Place the seasoned chicken pieces at the bottom of the crockpot, spreading them evenly.

3. Add the broccoli florets on top of the chicken.

4. Pour the creamy cheese sauce evenly over the chicken and broccoli, ensuring thorough coverage.

Step 5: Cook Low and Slow

1. Cover and set your crockpot to Low heat for 4-6 hours or High for 2-3 hours.

2. The chicken should be fully cooked (internal temperature of 165°F/74°C), and the broccoli tender but not mushy.

Important: Avoid opening the crockpot frequently, as this extends cooking time and lowers temperature.

Step 6: Check for Doneness and Final Touches

1. Once the cooking time is complete, check that the chicken is cooked through and the sauce has thickened slightly.

2. If you prefer a thicker sauce, remove the lid and cook on High for an additional 15-30 minutes to reduce excess liquid.

3. Optionally, sprinkle extra shredded cheddar cheese on top and cover for 5 minutes to melt before serving.

Step 7: Serve and Enjoy

1. Carefully scoop portions onto plates or bowls.

2. Garnish with fresh chopped parsley or chives for a fresh herbal note.

3. Serve alone or with keto-friendly sides such as cauliflower rice, mashed cauliflower, or a crisp green salad.

Optional Add-Ins and Variations

• Add mushrooms or spinach to increase veggie content and add flavor complexity.

• Stir in crushed red pepper flakes or smoked paprika for a bit of heat.

• Incorporate bacon bits for extra fat and smoky flavor.

• For a ranch-inspired casserole, add a packet of ranch seasoning to the cheese sauce.
