There’s just something wonderful about the way the sweet and sour chutney balances the savory chicken. If you don’t have mango chutney on hand, you can easily make your own chutney-based sauce with a couple mangos, onions, ginger, spices, and some sugar and vinegar. Perfect for a quick and easy mid-week meal! Add the chopped mango, ginger, raisins, mustard seeds, red pepper flakes, vinegar, water, and sugar. Bring to a simmer, reduce heat to low, cover the pan, and let cook gently for 30 minutes. Rinse the chicken thighs in water, pat dry. Rub some olive oil all over the chicken pieces, sprinkle with salt and pepper. Place chicken pieces in roasting pan. Cook in oven until the juices run clear when poked with a sharp knife, or when the internal temperature of the thighs is 170°F, about 25 minutes. If the chicken pieces are not browned enough for you, you can finish them in the broiler for the last 5 minutes of cooking. If your chicken pieces are extra large, after 25 minutes, lower the heat to 350°F and cook until the chicken pieces are cooked through. Put mango sauce into the roasting pan with remaining chicken drippings. Spread the sauce over the whole bottom of the pan. Let sit for a few minutes to soften the drippings, then scoop up and place into a serving dish. Adjust seasonings. If too acidic, add more sugar. Add salt to taste. Serve chicken with mango chutney sauce and steamed rice or Spanish rice.
