Step 1: Prep the Ingredients
Chop the onion and mince the garlic. Grate the ginger finely so it melts into the sauce. Cut the chicken into bite-sized pieces and set everything aside.

Step 2: Add Everything to the Slow Cooker
Place the chicken, onion, garlic, and ginger in the slow cooker. Pour in the tomato sauce and coconut milk. Sprinkle the garam masala, cumin, paprika, salt, and pepper over the top.

Use a spoon to stir everything together until the chicken is well coated in the sauce and spices. Spread it out evenly in the slow cooker.

Step 3: Cook Low and Slow
Cover and cook on low for 6–7 hours or high for 3–4 hours, until the chicken is tender and cooked through. Stir once or twice during cooking if you can, but it’s not essential.

Step 4: Taste and Finish
Before serving, give the tikka masala a stir and taste for seasoning. Adjust with more salt, pepper, or a dash of garam masala if needed.

Garnish with fresh cilantro just before serving.

Step 5: Serve and Enjoy
Spoon the chicken tikka masala over bowls of hot basmati rice or alongside fluffy naan bread. Serve with lime wedges or a dollop of yogurt if desired.
