This slow cooker chicken tikka masala recipe delivers tender chicken in a rich, creamy tomato sauce with classic Indian flavors, made easy in the crockpot.
Season the Chicken: Cut chicken into large bite-sized pieces. In a large bowl, toss chicken with salt, lemon juice, yogurt, chili powder, garam masala, turmeric, coriander, cumin, paprika, cayenne (if using), black pepper, ginger, and garlic. Let sit for 15–30 minutes if time allows (or proceed immediately).
Fill the Slow Cooker: Heat oil in a skillet over medium heat. Add diced onions and cook for 5–7 minutes, until softened and lightly golden. Transfer onions to the slow cooker. Add marinated chicken and tomato purée. Stir gently to combine.
Slow Cook: Cover and cook on LOW for 3 ½ to 4 hours, or HIGH for 2-3 hours until chicken is tender and cooked through.
Finish the Sauce: Stir in heavy cream, sugar (I find this balances the flavor), and tomato paste. Cook on HIGH for 20 minutes. Taste and adjust salt or spice as needed. Stir in chopped cilantro just before serving. Enjoy!
Notes
Chicken thighs stay extra juicy and are ideal for the slow cooker. If using breasts, check at the earlier end of the cooking time.
Kashmiri chili powder adds color and mild heat; regular chili powder will be spicier, but still delicious.
Serve with basmati rice, naan, or cauliflower rice.
Leftovers taste even better the next day and this recipe freezes well for up to 3 months.
