Common Mistakes to Avoid
- Adding the dairy too early: Greek yogurt and cottage cheese can separate or become grainy during prolonged slow cooking, so add them near the end.
- Using frozen cauliflower rice without accounting for moisture: Excess water can make the casserole soupy, so thaw and drain frozen cauliflower rice first.
- Overcooking the chicken: Cooking substantially beyond the recommended time can make chicken breast dry and stringy.
- Adding too much liquid: Cauliflower releases moisture as it cooks, so the recipe intentionally uses only a small amount of broth.
Required Equipment
- 6-quart slow cooker — provides enough space for even cooking and easy mixing.
- Large mixing bowl — makes combining the creamy ingredients simple.
- Wooden spoon or silicone spatula — helps distribute ingredients without scratching the cooker.
- Two forks — make shredding the cooked chicken quick and easy.
- Measuring cups and spoons — keep the casserole’s liquid and seasoning ratios consistent.
Storage Instructions
Let the casserole cool before transferring leftovers to airtight glass or BPA-free food containers. Refrigerate within a reasonable time after cooking and use within 3–4 days.
For freezing, portion the completely cooled casserole into freezer-safe containers. Freeze for up to 2 months for best quality. Thaw overnight in the refrigerator before reheating.
For meal prep, individual portions are especially convenient. The casserole remains protein-rich after refrigeration or freezing, although cauliflower rice may become somewhat softer after thawing.

📝 Ingredients
For the Casserole
- 2 lb (900 g) boneless, skinless chicken breasts
- 5 cups (600 g) cauliflower rice, fresh or frozen
- 1 cup (225 g) low-fat cottage cheese
- 1 cup (225 g) plain nonfat Greek yogurt
- 1 cup (100 g) shredded part-skim mozzarella cheese
- 1/2 cup (50 g) shredded sharp cheddar cheese
- 1/2 cup (120 ml) low-sodium chicken broth
- 1 small yellow onion (about 100 g), finely diced
- 3 cloves garlic, minced
- 1 tbsp Dijon mustard
- 1 tsp smoked paprika
- 1 tsp Italian seasoning
- 1/2 tsp onion powder
- 1/2 tsp black pepper
- 1/2 tsp salt, or to taste
- 1/4 tsp red pepper flakes — optional
- 2 tbsp chopped fresh parsley
Ingredient notes: If using frozen cauliflower rice, thaw it completely and squeeze out excess water before adding it. Low-fat cottage cheese and nonfat Greek yogurt help keep the casserole protein-forward without adding excessive fat.
Directions
- Prepare the slow cooker.
Lightly coat the inside of a 6-quart slow cooker with cooking spray or a small amount of olive oil. - Season the chicken.
Place the chicken breasts in the slow cooker. Sprinkle with smoked paprika, Italian seasoning, onion powder, black pepper, salt, and optional red pepper flakes. - Add the vegetables and broth.
Add the diced onion, minced garlic, cauliflower rice, and chicken broth. Spread everything into an even layer around and over the chicken. - Slow cook the chicken.
Cover and cook on LOW for 5–6 hours or HIGH for 3–4 hours, until the chicken reaches a safe internal temperature and is tender enough to shred easily. - Shred the chicken.
Transfer the cooked chicken to a plate or bowl. Let it rest for 3–5 minutes, then shred it with two forks. Return the shredded chicken to the slow cooker. - Prepare the creamy mixture.
In a separate bowl, whisk together cottage cheese, Greek yogurt, and Dijon mustard until reasonably smooth. A blender can be used if you prefer an especially silky texture. - Add the dairy mixture.
Turn the slow cooker to LOW or WARM. Stir the cottage cheese and Greek yogurt mixture into the chicken and cauliflower rice. Mix gently until evenly distributed. - Add the mozzarella.
Stir in about half of the mozzarella. The residual heat should begin melting it into the casserole. - Top with cheese.
Sprinkle the remaining mozzarella and cheddar evenly over the surface. Cover the slow cooker and cook on LOW/WARM for 10–15 minutes, until the cheese is completely melted. - Check the texture.
The finished casserole should be creamy and thick rather than watery. If it seems slightly loose, leave the lid ajar for 5–10 minutes on WARM to allow some moisture to escape. - Finish and serve.
Sprinkle with fresh parsley and let the casserole stand for 5 minutes before serving. This allows the creamy filling to settle slightly.
High-protein cooking tip: Add the Greek yogurt and cottage cheese near the end instead of exposing them to several hours of slow cooking. This helps maintain a smoother texture while keeping the recipe’s protein-rich ingredients intact.
