CrockPot Butter Chicken with Butternut Squash and Spices

This aromatic slow cooker butter chicken combines tender chicken thighs with warm Indian spices, butternut squash, and golden raisins for a comforting meal. The rich tomato-based sauce gets its depth from garam masala, turmeric, and fresh ginger, while half and half creates the signature creamy finish. Perfect for busy weeknights when you want restaurant-quality flavors with minimal effort. The addition of butternut squash and spinach makes this version heartier than traditional recipes, while serrano peppers add just the right amount of heat.

FAQ
Can I use chicken breasts instead of thighs?
Yes, but thighs stay more tender during long cooking. If using breasts, check at 4 hours on low to avoid overcooking.
Can I make this dairy-free?
Replace half and half with full-fat coconut milk for similar richness. Add it in the final 10 minutes just like the dairy version.
How long will leftovers keep?
Store covered in refrigerator up to 4 days. Reheat gently on stovetop or microwave, adding splash of stock if needed to thin sauce.
