Our classic Romesco Sauce, made with tomatoes, sweet peppers, and almonds really makes this roast chicken breast dish special.
Preheat oven to 450 degrees. In a small bowl, combine thyme, sugar, 1 teaspoon coarse salt, and teaspoon pepper. Place chicken on a rimmed baking sheet; rub with thyme mixture.
Bake until chicken is opaque throughout and an instant-read thermometer registers 165 degrees when inserted in thickest part of breast (avoiding bone), 25 to 35 minutes. Serve chicken topped with romesco sauce.
