Serve this curry ladled into bowls over steaming basmati rice or coconut rice (rice where half or more of the cooking water is replaced with coconut milk). If desired, experiment with adding different vegetables to the curry, like cauliflower, green beans or potatoes.
¼ cup plus 2 tablespoons vegetable oil
1 large onion, finely chopped
2-inch piece fresh ginger, peeled and finely chopped
4 large cloves garlic, finely chopped
½ teaspoon ground turmeric
½ teaspoon ground cumin
½ teaspoon ginger powder
½ teaspoon ground coriander
¼ teaspoon cayenne pepper
¼ teaspoon ground cardamom
1 14.5-ounce can diced tomatoes
1 cup chicken or vegetable broth
1 ½ pounds broccoli, chopped into small florets
1 medium sweet potato (about ½ pound), peeled and cut into ¾-inch pieces
1 medium red bell pepper, seeds removed, cut into ½-inch pieces
1 ½ pounds boneless, skinless chicken breasts, cut into 1-inch pieces
salt and pepper
1 13.5-ounce can coconut milk
½ cup roughly chopped fresh cilantro, plus more for serving
1) Heat the 1/4 cup oil in a large saucepan set over medium heat. Add the onions, fresh ginger and garlic, and cook, stirring occasionally, until softened, about 5 minutes. Add the turmeric, cumin, ginger, coriander, cayenne and cardamom, and cook, stirring, until fragrant, 1–2 minutes.
2) Add the tomatoes with their juice and bring to a simmer. Stir in the broth, broccoli, sweet potato and red pepper (it is okay if the vegetables are not submerged); raise heat to medium high, bring to a boil, then cover the saucepan, lower the heat to low, and cook until vegetables are just tender, 8–10 minutes.
3) Meanwhile, heat remaining 2 tablespoons oil in a medium pan set over medium heat. Add the chicken, and season with salt and pepper. Cook, stirring occasionally, until lightly browned, about 5 minutes. Add browned chicken, coconut milk and 1/2 cup cilantro to the saucepan; raise heat to medium and bring to a simmer, then lower heat back to low and cook, partially covered, until vegetables are tender but not mushy, and the sauce has thickened slightly, about 10 minutes. Season generously with salt and pepper, and serve topped with more chopped cilantro.
