  • Preheat the oven to 400°F (200°C).
  • In a bowl, mix red grapes with balsamic vinegar, olive oil, salt, and pepper.
  • Place chicken in a baking dish, surround with grape mixture, and sprinkle with fresh rosemary.
  • Roast until the chicken is cooked through, and the grapes are caramelized.

Red Grapes in Desserts: Red grapes can add a burst of sweetness to various desserts. Their natural sugars can enhance the flavor of baked goods, sauces, and even ice cream. Consider making a red grape compote as a topping for cheesecake or incorporating them into a grape and almond tart.

Recipe Example: Red Grape and Almond Tart


  • Pie crust
  • Red grapes
  • Almond meal
  • Sugar
  • Eggs
  • Butter
  • Vanilla extract


  • Pre-bake the pie crust according to the package instructions.
  • In a bowl, mix almond meal, sugar, eggs, melted butter, and vanilla extract.
  • Spread the almond mixture onto the pie crust.
  • Arrange halved red grapes on top and bake until the filling is set and golden.

How Does it Compare to Other Foods?

Red Grapes vs. Other Fruits: Compared to other fruits, red grapes are relatively low in calories and high in antioxidants. While they may not be as rich in vitamin C as citrus fruits, they offer unique health benefits due to their resveratrol content. Resveratrol has been associated with heart health and may contribute to improved insulin sensitivity.
