Lemon curd is a bright, tangy, and creamy spread that adds a burst of citrus flavor to many desserts and breakfast dishes. While the traditional version uses eggs and butter to thicken the curd, a simpler and equally delicious method uses cornstarch as the thickening agent. Making lemon curd with cornstarch is perfect for those who want a smooth, egg-free option or just prefer a lighter, more stable version of this popular treat. Whether you’re spreading it on toast, swirling it into yogurt, or using it as a tart filling, this method delivers rich flavor and a velvety texture.
What Is Lemon Curd with Cornstarch?
Lemon curd with cornstarch is a variation of the classic lemon curd that uses cornstarch to thicken the mixture instead of relying solely on eggs. This method produces a smooth, glossy curd with a bright lemon flavor. It’s often used as a filling for cakes, tarts, pies, and pastries, or as a topping for scones, pancakes, and toast. The use of cornstarch makes the curd more stable, which is especially helpful in warm weather or for make-ahead desserts.
Benefits of Using Cornstarch
Cornstarch offers several advantages in lemon curd recipes:
- No eggs needed: Great for people with egg allergies or those following a vegan diet (if butter is also substituted).
- Consistent results: Cornstarch thickens reliably and creates a smooth, pudding-like consistency.
- Stays stable: The texture of lemon curd with cornstarch holds up well in tarts and layered desserts.
Basic Ingredients
Making lemon curd with cornstarch doesn’t require many ingredients, and most are easy to find. Here’s what you’ll typically need:
- Fresh lemon juice
- Lemon zest (for extra flavor)
- Granulated sugar
- Cornstarch
- Water
- Butter (for richness and a glossy finish)
- A pinch of salt (optional but enhances flavor)
Optional Additions
Some recipes may include a few drops of vanilla extract for a rounded flavor or a bit of turmeric for a natural yellow color. These are entirely optional but can enhance the final result.
How to Make Lemon Curd with Cornstarch
Making lemon curd with cornstarch is easy and takes less than 20 minutes. Here’s a step-by-step guide:
Step 1: Combine Dry Ingredients
In a saucepan, mix together sugar, cornstarch, and a pinch of salt. Stir until well combined. This prevents clumps when the liquid is added.
Step 2: Add Liquids
Slowly pour in the water and lemon juice while stirring constantly. Add the lemon zest at this stage. Stir well to ensure everything is blended smoothly.
Step 3: Cook Until Thickened
Place the saucepan over medium heat and cook the mixture while stirring continuously. After a few minutes, it will start to thicken. Be patient and don’t walk away, as the cornstarch can clump if left unattended.
Step 4: Remove from Heat and Add Butter
Once the curd has thickened to a pudding-like consistency, remove it from the heat and stir in the butter until fully melted and combined. The butter adds richness and a silky finish to the curd.
Step 5: Cool and Store
Let the curd cool slightly, then pour it into a jar or bowl. Cover it and refrigerate for at least an hour. As it cools, it will continue to set and develop flavor. Store in the fridge for up to one week.
How to Use Lemon Curd with Cornstarch
This versatile spread can be used in a variety of sweet dishes. Here are some popular ways to enjoy it:
- Tart filling: Spoon into pre-baked tart shells for a quick dessert.
- Layered desserts: Add to trifles or parfaits for a citrus twist.
- Spread on toast: Replace your regular jam or jelly with lemon curd.

Pairing Ideas
Lemon curd pairs beautifully with:
- Fresh berries like strawberries, blueberries, and raspberries
- Whipped cream or yogurt
- Shortbread cookies and scones
- Angel food cake or pound cake
Tips for Success
To get the best results when making lemon curd with cornstarch, keep these tips in mind:
- Use fresh lemons: Bottled lemon juice won’t give the same bright flavor as fresh juice and zest.
- Stir constantly: This prevents the cornstarch from clumping and ensures even cooking.
- Don’t overcook: Once thickened, remove from heat immediately to avoid breaking down the cornstarch structure.
- Strain if needed: For an ultra-smooth texture, strain the curd before storing.
Thickening Too Much?
If your lemon curd becomes too thick, you can gently reheat it and add a splash of water or lemon juice to loosen it to your desired consistency.
Storage and Shelf Life
Lemon curd made with cornstarch should be kept in an airtight container in the refrigerator. It stays fresh for about 5 to 7 days. Because this version doesn’t contain eggs, it tends to be more stable than traditional curd, making it ideal for batch preparation.
If you’d like to freeze lemon curd, let it cool completely, then store it in a freezer-safe container. It can be frozen for up to two months. Thaw in the refrigerator overnight before using.
Why Choose Cornstarch Lemon Curd?
There are several reasons why many bakers choose this version of lemon curd:
- Allergy-friendly: No eggs makes it suitable for more people.
- Consistent texture: Cornstarch provides a smoother and more predictable result.
- Simpler prep: No tempering eggs or worrying about curdling.
- Budget-friendly: Fewer ingredients and no need for specialty tools.
It’s especially helpful for novice bakers or anyone looking to simplify their baking process without sacrificing flavor or quality.
