3 pieces naan bread
1 red onion, halved and thinly sliced
1 pound baby red-skinned potatoes, halved or quartered if large
1 fresno chile or red jalapeno pepper, halved lengthwise, seeded and sliced
1 small bunch cilantro, leaves and tender stems separated, chopped
1 1/2 pounds skinless, boneless chicken thighs (about 6)
1 tablespoon garam masala
kosher salt and freshly ground pepper
2 tablespoons unsalted butter, cut into pieces
1 cinnamon stick
1 15-ounce can tomato sauce
1/2 cup heavy cream
kosher salt
1. Crumble 1/2 piece naan into coarse crumbs; transfer to a 6-quart slow cooker. Add the red onion, potatoes, chile and cilantro stems.
2. Arrange the chicken thighs in a single layer over the vegetables and sprinkle with the garam masala, 3/4 teaspoon salt and a few grinds of pepper.
3. Dot with the butter and add the cinnamon stick. Pour the tomato sauce over the top. Cover and cook on low, 7 hours.
4. Uncover and switch to the warm setting or turn off. Gently stir in the heavy cream, breaking the chicken into large chunks; let stand 10 minutes. Stir in the cilantro leaves and season with salt. Serve with the remaining naan.
