I love making this creamy sourdough ice cream whenever I have extra sourdough starter sitting in my kitchen. The tangy flavor from the sourdough pairs perfectly with the rich cream and sweet vanilla, creating a smooth homemade dessert that feels both unique and comforting. I find that this recipe gives classic ice cream a slightly complex flavor while still staying creamy and refreshing.
Why You’ll Love This Recipe
I enjoy this recipe because it transforms leftover sourdough starter into something completely unexpected. The slight tang balances the sweetness beautifully, and the texture stays incredibly creamy after freezing. I also appreciate how simple the ingredients are since I usually already have most of them at home. This ice cream tastes homemade in the best possible way, with a rich custard-like base and a subtle sourdough depth that makes every scoop memorable.
Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
2 cups heavy cream
1 cup whole milk
3/4 cup granulated sugar
1/2 cup active sourdough starter
4 large egg yolks
1 teaspoon vanilla extract
1/4 teaspoon salt
Directions
I whisk the egg yolks and sugar together in a medium bowl until the mixture becomes pale and smooth.
In a saucepan over medium heat, I combine the heavy cream, whole milk, and salt. I warm the mixture until it begins to steam but not boil.
I slowly pour a small amount of the warm cream mixture into the egg yolks while whisking constantly to temper the eggs.
I return the tempered mixture back into the saucepan and cook it over low heat, stirring continuously, until the custard thickens slightly enough to coat the back of a spoon.
I remove the saucepan from the heat and stir in the sourdough starter and vanilla extract until fully combined.
I strain the custard through a fine mesh sieve for an extra smooth texture.
I chill the mixture in the refrigerator for at least 4 hours, though I usually leave it overnight for the best flavor.
Once chilled, I pour the custard into my ice cream maker and churn according to the manufacturer’s instructions.
I transfer the churned ice cream into a freezer-safe container and freeze for 3 to 4 hours before serving.
Servings and Timing
Servings: 6 servings
Prep Time: 15 minutes
Cook Time: 10 minutes
Chilling Time: 4 hours
Churning Time: 25 minutes
Total Time: About 4 hours 50 minutes
Variations
I sometimes mix chocolate chips or crushed cookies into the ice cream during the final minutes of churning for added texture. Fresh berries also work wonderfully with the tangy sourdough flavor. When I want a warmer flavor profile, I add a pinch of cinnamon or nutmeg to the custard base. For a caramel-style version, I drizzle salted caramel sauce into the churned ice cream before freezing.
storage/reheating
I store the ice cream in an airtight container in the freezer for up to 2 weeks. To keep the texture creamy, I press a layer of parchment paper or plastic wrap directly onto the surface before sealing the container. Before serving, I let the ice cream sit at room temperature for about 5 minutes so it softens slightly and scoops more easily. I never reheat ice cream, but I do allow it to thaw gently for the best consistency.
FAQs
Can I use discard sourdough starter instead of active starter?
I can use sourdough discard as long as it smells fresh and pleasant. The flavor may be slightly tangier, which I personally enjoy in this recipe.
Do I need an ice cream maker?
I get the creamiest texture with an ice cream maker, but I can also freeze the mixture in a container and stir it every 30 minutes until firm.
What does sourdough add to the ice cream?
I find that sourdough adds a gentle tanginess and subtle depth that balances the sweetness beautifully.
Can I make this recipe without eggs?
I can make an egg-free version by thickening the base with a small amount of cornstarch instead of egg yolks, though the texture will be slightly different.
How long does homemade sourdough ice cream last?
I usually enjoy it within 2 weeks for the freshest flavor and creamiest texture.
