This classic roast chicken with potatoes and onions is the ultimate high-protein comfort meal. By infusing the meat with fresh rosemary and garlic under the skin, you ensure every bite is succulent and aromatic. This method produces beautifully golden skin and tender meat, while the potatoes and onions roast underneath, absorbing the savoury juices and herbs for a depth of flavour that shop-bought rotisserie chicken simply cannot match.
Ideal for a traditional Sunday lunch or a nutritious midweek dinner, this recipe is designed with efficiency in mind. By roasting two chickens at once, you can enjoy a fresh, homemade meal tonight and keep the second bird for salads, sandwiches, or a hearty soup tomorrow. Serving the carved chicken with the natural pan juices provides a light yet rich finish that highlights the quality of the ingredients.

How to make Roast Chicken with Potatoes and Onions
Back to contentsWash chickens; pat dry. Starting at neck end, slide fingers under breast skin. Slide 2 rosemary sprigs and several garlic slices onto each breast half. Rub outside of each chicken with 1 teaspoon sea salt and 1/2 teaspoons pepper. Fold wing tips under; tie legs together. Wrap in plastic; chill 4 hours.
Position 1 rack in top third and 1 rack in bottom third of oven; preheat to 191°C. Spread 1 tablespoon butter all over each chicken. Place chickens, breast side down, on rack set on large rimmed baking sheet. Pour wine and water onto baking sheet.
Coat another large rimmed baking sheet with nonstick spray. Toss potatoes, onions, chopped rosemary, unpeeled garlic cloves, and olive oil in large bowl; spread vegetables on prepared sheet and sprinkle with salt and pepper. Place chickens on top rack of oven and vegetables on bottom rack. Roast 30 minutes. Turn chickens over; stir vegetables. Roast chickens until thermometer inserted into thickest part of thigh registers 71°C, about 45 minutes longer. Let chickens rest 15 minutes. Continue roasting vegetables until brown and tender, about 30 minutes longer.
Transfer 1 chicken to cutting board; reserve second for soup (recipe follows). Remove rack from baking sheet; scrape pan juices into small bowl. Spoon off fat. Carve chicken on cutting board; reserve carcass for soup. Arrange chicken and vegetables on platter. Serve with pan juices.
