Blueberry-Swirl Buttermilk Ice Cream

This gorgeous homemade ice cream is a showstopper, thanks to bold swirls of blueberry syrup that cut through tart buttermilk-yogurt cream.


  • 2 large eggs
  • ½ cup sugar plus ¼ cup, divided
  • ¼ teaspoon salt
  • 1 cup buttermilk
  • 2 cups whole-milk plain Greek yogurt
  • 1 (12 ounce) package frozen unsweetened blueberries
  • 2 tablespoons lemon juice
  • Blueberries & mint for garnish


  • Prep
  • Ready In
  1. Whisk eggs, ½ cup sugar, and salt in a heavy saucepan until slightly thick. Whisk in buttermilk. Cook over medium-low heat, stirring constantly, until the mixture coats a metal spoon and reaches 165°F, about 10 minutes. Set the pan in a bowl of ice water and stir until cooled. Stir in yogurt. Refrigerate for 8 to 24 hours.
  2. Meanwhile, combine blueberries, the remaining ¼ cup sugar, and lemon juice in a small saucepan. Bring to a boil over medium-high heat, whisking frequently. Reduce heat and simmer until syrupy, about 5 minutes. Let cool. Transfer to a bowl and refrigerate for 8 to 24 hours.
  3. Freeze the chilled buttermilk mixture in a 1½- or 2-qt. ice cream maker according to manufacturer's directions. Transfer to a freezer container. Swirl in the blueberry mixture. Freeze until firm, 6 to 8 hours.
  4. Let stand at room temperature for 20 to 30 minutes before serving. Garnish with fresh blueberries and mint, if desired.
