  • 1 large Vidalia onion peeled and root end removed
  • 1 tsp neutral vegetable oil grapeseed or sunflower
  • 1 tsp unsalted butter
  • 1-1/2 TBS unflavored brandy
  • 2 cups heavy cream
  • 1-1/2 cups whole milk
  • 1-1/2 cups granulated sugar
  • 1/4 tsp pure vanilla extract
  • 1/4 tsp sea salt
  • 2 tsps minced chives
  • 1/4 cup dry roasted peanuts optional


  • Cut the onion in half and cut into thin slices. In a sauté pan over medium heat, warm the oil. Add the onion slices and cook until they are soft and a caramel color, approximately 40 minutes. You will need to stir often to prevent burning. Reduce the heat to medium-low if the onions are turning a darker color too quickly.
  • Once the onions are the color of maple syrup, add the brandy and deglaze the pan until the alcohol burns off. You will know when there is no longer a smell of liquor and the onions are only slightly moist.
  • Measure out 2/3 cup of the onions. If there are extra, use them to flavor soups or to spread on toast. Place the 2/3 cup in a saucepot over high heat with the cream, milk, sugar, vanilla, and salt. Bring just to a boil and remove the pot from the heat. Do not allow the cream to boil over. Set aside to steep and cool for 15 minutes.
  • Transfer the dairy and onion mixture to a blender. Blend until smooth and creamy.
  • Place the ice cream base in a shallow metal pan. Stir in the chives and peanuts, if desired. Place the pan in the freezer. Stir every 20 minutes for approximately 2 to 3 hours until the desired consistency is achieved.
  • Scoop or spoon into bowls and enjoy.
