Homemade Lemon Custard Ice Cream Recipe

Lemon custard ice cream is a rich, egg-yolk–based ice cream flavored with fresh lemon zest and lemon juice. If you can make a crème anglaise or any custard sauce, you can make this bright, creamy lemon ice cream at home.

Two styles of ice cream

Home and commercial ice creams typically follow one of two approaches:

• Custard-based ice cream — made with egg yolks (sometimes whole eggs). This style starts with a crème anglaise, giving a silky texture and a rich, rounded flavor.
• Philadelphia-style ice cream — made without eggs, relying on milk and cream for texture and sweetness.

I prefer custard-based ice creams because the yolks add flavor, color, and a smoother mouthfeel, even with simple flavors like vanilla. In this lemon custard ice cream the result is reminiscent of creamy lemon curd or a lemon creamsicle: bright citrus balanced by a lush, custardy base.

This recipe is adapted from classic custard ice cream methods. The key steps are simple: infuse the dairy with lemon, temper hot dairy into whisked egg yolks, cook gently until the custard thickens, chill thoroughly, then churn and finish in the freezer.

Why the yolks matter

Egg yolks provide three important things: flavor, color, and emulsifying/thickening power. To ensure a smooth custard, whisk the yolks with sugar until very pale and light — a process often called blanchir — which incorporates air and helps dissolve sugar. If you skip this step you risk ending up with flecks of cooked yolk and a less stable custard.

Custard-based ice creams should be cooked on the stove like any crème anglaise, then strained, cooled, and chilled completely before churning. Once churned, homemade custard ice cream tends to freeze firmer than some soft commercial brands. For the best scoopable texture, remove from the freezer for 10–15 minutes before serving.

Equipment

• Whisk
• Wooden spoon
• Medium saucepan
• Fine strainer
• Ice cream maker (frozen drum or compressor model)
• Container for freezing

📖 Recipe — Lemon Custard Ice Cream

Yields: about 6 servings

Prep time: 25 minutes (plus chilling)

Cook time: 10 minutes

Chill time: 4 hours or overnight

Total active time: ~30 minutes

Ingredients

• 375 mL whipping cream (35% fat), divided
• 5 large egg yolks
• 150 g granulated sugar, divided
• 375 mL whole milk (3.25% fat)
• 125 mL fresh lemon juice
• 15 mL finely grated lemon zest
• 5 mL fine kosher salt (reduce by half if using table salt)

Instructions

1. Freeze the ice cream drum or prepare your machine according to manufacturer instructions (if using a frozen bowl, allow it to chill at least 24 hours).
2. Place 250 mL (1 cup) of the cold whipping cream in a 1 L (4-cup) measuring cup and set a fine strainer over it. Set aside.
3. In a large bowl, whisk the egg yolks with half the sugar until the mixture becomes very pale and light in color.
4. In a medium saucepan, whisk the remaining sugar with the milk, the remaining 125 mL (½ cup) cream, the lemon juice, lemon zest, and salt. Heat over medium until the mixture is very hot and almost at a boil.
5. To temper the yolks, slowly pour the hot milk mixture into the whisked yolks while whisking continuously until fully combined, then return the mixture to the saucepan.
6. Switch to a wooden spoon and, stirring constantly, heat the mixture over medium–low until it thickens and reaches about 83°C (181°F). The mixture should coat the back of a spoon.
7. Pour the custard through the strainer set over the reserved cream, pressing gently to pass the mixture through and remove any solids.
8. Cover the custard with plastic wrap (touching the surface to prevent a skin) and refrigerate until completely cold, at least several hours or overnight.
9. Churn in your ice cream maker according to the machine’s instructions. Depending on your machine, churning can take 15 minutes or longer.
10. When the ice cream reaches a soft-serve consistency, transfer it to a container, seal, and freeze for a few hours to firm up before serving.

Notes

• If you use standard table salt instead of a light kosher salt, use roughly half the amount listed to avoid over-salting.
• Homemade custard ice cream will be firmer from the freezer than many commercial brands. Let it sit at room temperature for 10–15 minutes before scooping for the best texture.
• For brighter lemon flavor, use freshly squeezed juice and finely grated zest from unwaxed lemons.
