Slow Cooker Butter Chicken

2 tablespoons butter

2 tablespoons vegetable oil

4 large skinless, boneless chicken thighs, cut into bite-sized pieces

1 onion, diced

3 cloves garlic, minced

2 teaspoons curry powder

1 tablespoon curry paste

2 teaspoons tandoori masala

1 teaspoon garam masala

1 (6 ounce) can tomato paste

15 green cardamom pods

1 cup low-fat plain yogurt

1 (14 ounce) can coconut milk

salt to taste

Melt the butter and vegetable oil in a large skillet over medium heat. Stir in the chicken, onion, and garlic. Cook and stir until the onion has softened and turned translucent, about 10 minutes. Stir in the curry powder, curry paste, tandoori masala, garam masala, and tomato paste until no lumps of tomato paste remain. Pour into a slow cooker, and stir in the cardamom pods, coconut milk, and yogurt. Season to taste with salt.

Cook on High 4 to 6 hours, or on Low 6 to 8 hours until the chicken is tender and the sauce has reduced to your desired consistency. Remove and discard the cardamom pods before serving.
