Roasted Chicken Thighs with Peanut Butter Barbecue Sauce

Make the barbecue sauce: In a medium saucepan, heat oil. Add onion and cook over moderate medium heat, stirring occasionally, until softened, about 2 minutes. Add tomato paste and cook, stirring, until lightly caramelized and deepened in color, about 2 minutes. Whisk in the remaining ingredients and 6 tablespoons water. Simmer until flavors are combined, and the sauce is slightly thickened, about 5 minutes.

Make the chicken: Heat oven to 425 degrees. Set a rack over a rimmed baking sheet.

In a large bowl, combine chicken, oil and 1/4 cup of the barbecue sauce and season with salt. Toss to evenly coat and arrange on the rack. Roast, using a brush to baste with the remaining 1/2 cup sauce every 10 minutes, until the chicken is cooked through and deep golden in color, about 30 minutes. Serve with the leftover sauce on the side, or store sauce in the refrigerator for later use.
