Add Ingredients: Place chicken breasts in the slow cooker. Pour Italian dressing over the chicken and sprinkle brown sugar evenly on top. Optionally, add sliced onions.
Cook: Cover and cook on low for 6–7 hours or high for 3–4 hours, until chicken is tender and fully cooked (internal temperature 165°F / 74°C).
Serve: Spoon sauce over chicken and serve with your favorite sides, such as rice, potatoes, or roasted vegetables.
