In a large bowl, combine the crushed tomatoes, coconut milk, butter, minced garlic, minced ginger, and all spices (garam masala, cumin, turmeric, paprika, cayenne pepper, and salt). Mix well to create a smooth sauce.
Place the chicken thighs in the bottom of the crockpot, ensuring they are spread out evenly.
Pour the prepared sauce mixture over the chicken, covering it completely.
Set the crockpot to low heat and cook for 6-8 hours or on high for 3-4 hours until the chicken is tender and cooked through.
Once cooking is complete, shred the chicken inside the crockpot using two forks and mix it well with the sauce.
Adjust the seasoning if necessary, adding more salt or spices according to your taste preference.
Serve the butter chicken over steamed rice or with naan bread for a delicious meal. Garnish with fresh cilantro before serving.
Notes
Adjust the cayenne pepper for desired spice level.
