This vegan lemon curd delivers rich, tangy-sweet spread flavor and texture without any animal products. Soymilk and margarine work as plant-based substitutes, creating that creamy consistency you’re looking for. The cornstarch thickens everything while the lemon juice brings that signature tartness. You’ll see the mixture change from cloudy to crystal-clear as it boils, which shows it’s thickening right. Once cooled and refrigerated, it keeps getting firmer. This vegan version spreads easily on toast, swirls into yogurt, or fills pastries – all without losing any taste or texture.
The Vegan Lemon Curd Ingredients
This vegan lemon curd uses simple pantry staples that come together to form a rich, tangy spread perfect for pastries, toast, or dessert fillings. Plant-based alternatives replace traditional dairy while keeping the classic bright citrus flavor and creamy texture that makes lemon curd so beloved.
Vegan Lemon Curd (Easy Sauce Recipe)
by veganpreps.com

Ingredients
- 1 cup fresh lemon juice (from 4 to 5 lemons)
- 1/2 cup water
- 1 1/2 cups granulated sugar
- 4 tablespoons cornstarch
- 1/8 teaspoon salt
- 6 tablespoons unsweetened soymilk
- 2 tablespoons vegan margarine
Instructions
- 1In a medium mixing bowl, whisk together the lemon juice, water, sugar, cornstarch, and salt until the cornstarch is fully dissolved with no lumps.
- 2Pour the mixture into a heavy-bottomed saucepan. Place over medium heat and whisk continuously as the mixture heats up. Do not walk away — constant stirring prevents the cornstarch from clumping on the bottom.
- 3Continue whisking over medium heat for 8 to 10 minutes. The mixture will first turn opaque, then gradually become clear and noticeably thicker. This change signals the cornstarch has cooked through. The curd should coat the back of a spoon thickly.
- 4Remove the pan from the heat. Immediately whisk in the soymilk and vegan margarine until fully incorporated and the curd is smooth and glossy.
- 5Pour the finished curd into a clean jar or airtight container. Press a piece of plastic wrap directly onto the surface to prevent a skin from forming. Let cool to room temperature, then refrigerate for at least 2 hours before using. The curd will firm up as it chills and keeps refrigerated for up to 2 weeks.
Notes
- Store leftovers in an airtight container in the fridge for up to 4 days.
- This recipe freezes well for up to 3 months. Thaw overnight in the fridge before reheating.
- Adjust seasoning to taste after reheating, as flavors can mellow during storage.
Use fresh lemon juice rather than bottled varieties, as the quality directly impacts the final flavor. The cornstarch serves as the primary thickening agent, replacing eggs typically used in traditional lemon curd, while soymilk and margarine provide the dairy-free richness. Check that your margarine is specifically vegan to keep the recipe plant-based. The quality of these ingredients will determine how smooth and luxurious your finished curd becomes.
Whisk Constantly Over Medium Heat

Combine 1 cup lemon juice, 1/2 cup water, 1 1/2 cups granulated sugar, 4 tablespoons cornstarch, and 1/8 teaspoon salt in a mixing bowl. Pour the entire mixture into a heavy saucepan. Place the saucepan on the stove over medium heat and whisk the mixture continuously. This constant whisking stops lumps from forming and ensures heat spreads evenly throughout the curd.
Continue whisking over medium heat until the mixture reaches a full boil. You’ll notice the color beginning to change and the mixture starting to thicken as the cornstarch does its work. Once the mixture reaches a rolling boil, stop stirring and allow it to boil for exactly 1 minute without any stirring. During this minute, the curd will become noticeably thickened and should turn from opaque to clear, showing that the cornstarch has properly cooked and thickened the lemon mixture.
Remove the saucepan from heat immediately after the 1-minute boil. While the curd is still hot, add 6 tablespoons soymilk and 2 tablespoons margarine to the pan. Blend these additions in thoroughly using the whisk, making certain the margarine melts completely and incorporates evenly throughout the mixture. A heavy saucepan* is an essential tool for even heat distribution during vegan cooking. Allow the vegan lemon curd to cool to room temperature before transferring it to a covered container and refrigerating it. The curd will continue to thicken as it cools, reaching its final spreadable consistency.
Cornstarch Can Replace Arrowroot
Since cornstarch is a reliable thickening agent you likely already have in your pantry, you can use it in place of arrowroot powder in this vegan lemon curd recipe. Cornstarch works by absorbing liquid and swelling, which creates that smooth, pudding-like texture you’re after. Cornstarch performs especially well when you whisk it constantly over medium heat – this prevents lumps from forming and ensures even thickening. The four tablespoons called for in this recipe will give you the perfect consistency. Both starches work the same way, but cornstarch is more forgiving and affordable, making it the go-to choice for solid results every time.
Serve Over Fresh Berries
Once your vegan lemon curd has cooled and thickened, serve it over fresh berries to let those bright, tangy flavors stand out. Raspberries or blueberries work well because their tartness pairs with the lemon. Spoon the curd over a bowl of berries for a fancy dessert that comes together in minutes. The curd’s creamy texture contrasts nicely with the fruit’s natural juiciness. Layer it with vegan yogurt and granola for a more substantial breakfast option. This combination works great for dinner parties too – impressive without the fuss.
Final Thoughts
Making vegan lemon curd at home gives you full control over the ingredients and flavor, so you’ll end up with a fresher, tastier result than store-bought versions. This recipe is simple, so you can whip up a batch whenever you need it for desserts, breakfast spreads, or sauce. The cornstarch thickens everything without eggs, while soymilk and margarine create that rich, creamy texture you’d expect.
