4.8 from 56 reviews

This Lemon Custard Ice Cream is a creamy, tangy frozen treat made with a rich custard base enhanced by fresh lemon juice and zest. The addition of luscious lemon curd swirled through adds bursts of vibrant citrus flavor, making it a perfectly refreshing dessert for warm days. The recipe uses traditional stovetop cooking to create a smooth custard, which is then churned to achieve a velvety texture.

Ingredients

Scale

Custard Base

  • 1 cup whole milk
  • 2 cups heavy cream
  • ¾ cup granulated sugar, divided
  • 4 large egg yolks
  • 1½ tbsp lemon zest (zest before juicing)
  • ½ tsp vanilla extract
  • Pinch of salt

Flavoring

  • ½ cup fresh lemon juice
  • ½ cup lemon curd (to swirl in before final freeze)

Instructions

  1. Heat Milk and Cream: In a saucepan, combine the whole milk, heavy cream, half the granulated sugar (approximately ⅓ cup), and lemon zest. Warm the mixture over medium heat until it is steaming but not boiling. This infuses the cream with lemon flavor.
  2. Whisk Egg Yolks: In a separate bowl, whisk together the egg yolks, the remaining sugar, and a pinch of salt until the mixture becomes pale and thick. This ensures a smooth custard texture.
  3. Temper the Eggs: Slowly pour the warm milk and cream mixture into the whipped egg yolks while continuously whisking. This careful mixing prevents the eggs from curdling. Then, return the combined mixture to the saucepan.
  4. Cook the Custard: Over medium heat, stir constantly until the custard thickens and coats the back of a spoon, reaching a temperature of 170–175°F (77–80°C). Remove the saucepan from heat.
  5. Strain and Add Flavorings: Pass the custard through a fine mesh sieve to remove any cooked egg bits. Stir in the fresh lemon juice and vanilla extract to add brightness and depth of flavor.
  6. Chill the Base: Cover the custard base and refrigerate it for at least 4 hours, or preferably overnight, to chill thoroughly, which is essential for proper churning.
  7. Churn the Ice Cream: Pour the cold custard into your ice cream maker and churn according to the manufacturer’s instructions until it reaches a soft-serve consistency — about 20 to 25 minutes.
  8. Layer with Lemon Curd: Transfer half the churned ice cream to a container, then spoon half of the lemon curd over it. Gently swirl the curd into the ice cream without fully mixing. Repeat layering with the remaining ice cream and lemon curd. If preferred, you can skip the lemon curd swirl and just fill the container with the churned ice cream.
  9. Freeze Until Firm: Cover the container and freeze for at least 4 hours or until the ice cream is firm enough to scoop. Serve and enjoy your creamy, citrusy lemon custard ice cream.

Notes

  • Zesting the lemon before juicing ensures you get the maximum fresh zest without losing any to the juicing process.
  • Be careful not to overheat the custard when cooking; temperatures above 175°F may cause curdling.
  • If you don’t have an ice cream maker, you can place the custard in a shallow container in the freezer and stir every 30 minutes until frozen, though the texture may be less smooth.
  • Lemon curd swirl is optional but adds delightful texture and bursts of extra lemon flavor.
  • Using fresh lemon juice and zest provides a brighter, fresher flavor compared to bottled juice.
