Bake in the preheated oven, without moving or turning, until the internal temperature of the thickest part of the chicken reaches at least 165° F. This will take about 30-40 minutes, depending on the size of your chicken thighs. During the last 15 minutes, place the cherry tomatoes on baking tray & roast. Remove chicken thighs & tomatoes from oven. Slice thighs in 1/4-inch thick slices. Keep chicken & roasted tomatoes warm.
