Baked Chicken in Sweet and Tangy Red Pepper Sauce

This comforting baked chicken features tender pieces coated in seasoned flour and baked until golden, then smothered in a vibrant red pepper sauce. The sauce combines sweet bell peppers with onions in a slightly sweet and tangy glaze brightened with vinegar and a hint of heat from red pepper flakes. Perfect for weeknight dinners or Sunday family meals, this one-dish recipe delivers restaurant-quality flavors with minimal effort. The chicken stays moist from the initial butter coating while the sauce adds layers of flavor that complement rather than overpower the meat.
