Save this recipe on:

Lemon curd has always been one of those little luxuries I love to keep on hand — velvety smooth, bright with citrus, and just the right balance of sweet and tart. Whether I’m spreading it over toast, spooning it into tart shells, or swirling it into yogurt, this luscious lemon curd brings a touch of sunshine to every bite. I started making my own a few years ago, and I’ve never looked back. Once you taste the fresh, real-deal version, store-bought simply doesn’t compare.

The best part? It’s surprisingly easy to make at home. With just a handful of ingredients and a bit of careful stirring, you get a gorgeous golden spread that’s endlessly versatile. I love how quickly it comes together — and how impressive it feels even when I’m just slathering it on a biscuit for breakfast.

Why You’ll Love This Homemade Lemon Curd

This lemon curd is deeply flavorful with an ultra-smooth texture that’s both creamy and luxurious. You’ll love how it balances the vibrant acidity of fresh lemons with the richness of butter and the gentle sweetness of sugar. It’s ideal for filling cakes, layering in trifles, or simply eating by the spoonful (no judgment here). Plus, it stores beautifully, so you can make it ahead and enjoy a burst of citrus any day of the week.

What Kind of Lemons Should I Use?

Fresh, juicy lemons are essential for this recipe — ideally organic, since we use both the zest and juice. Meyer lemons are a fantastic option if you can find them: they’re sweeter and more floral than regular lemons, which makes for a slightly gentler, more aromatic curd. However, standard lemons work perfectly and deliver that signature tart punch.

---

Options for Substitutions

If you’re out of lemons or just want to experiment, you can substitute lime juice and zest for a vibrant lime curd, or even use blood oranges for a dramatic color twist and subtle sweetness. For a dairy-free version, swap the butter with a high-quality vegan butter. Want to reduce the sugar? You can slightly cut back without compromising texture — but avoid sugar substitutes, as they may affect the curd’s consistency.

Ingredients for this Homemade Lemon Curd

• Egg yolks – They create the luxurious, creamy base and help thicken the curd to that perfect pudding-like consistency.
• Granulated sugar – Balances the tartness of the lemon and contributes to the smooth texture.
• Fresh lemon juice – The key flavor component; it adds brightness and the signature citrus zing.
• Lemon zest – Infuses even more concentrated lemon flavor, enhancing the overall aroma and taste.
• Unsalted butter – Adds richness, silkiness, and helps stabilize the curd as it cools.
• Salt (just a pinch) – A small amount enhances the overall flavor and cuts the edge off the sweetness.

Step 1: Prepare Your Ingredients

Before you begin, separate your egg yolks from the whites (you’ll only need the yolks here), zest your lemons finely, and squeeze enough juice to get a fresh and vibrant flavor. This preparation step makes the process smoother and ensures everything’s ready to go.

---

Step 2: Whisk the Yolks and Sugar

In a medium heatproof bowl or saucepan, whisk together the egg yolks and granulated sugar until the mixture is pale and slightly thickened. This not only blends the ingredients but also helps begin the thickening process.

---

Step 3: Add Lemon Juice and Zest

Pour in the fresh lemon juice and add the zest. Stir everything to combine thoroughly. The acidity in the lemon juice is what will interact with the egg yolks to form the base of your curd.

---

Step 4: Cook Over Gentle Heat

Place the bowl over a saucepan of simmering water (double boiler method) or cook directly over low heat if using a heavy-bottomed saucepan. Stir constantly with a silicone spatula or wooden spoon, making sure to scrape the sides and bottom as it cooks. This will prevent curdling and ensure even thickening.

---

Step 5: Add Butter

Once the curd has thickened to coat the back of a spoon (about 10–12 minutes of stirring), remove it from the heat and stir in the butter, a few cubes at a time. The butter melts into the curd, giving it a silky, luxurious finish.

---

Step 6: Strain for Smoothness (Optional but Recommended)

For the smoothest lemon curd possible, pour the hot mixture through a fine mesh sieve into a clean bowl. This removes any bits of zest or accidental cooked egg.

---

Step 7: Cool and Store

Let the lemon curd cool slightly, then transfer it to a clean jar or airtight container. Once cooled completely, store it in the fridge. It will thicken further as it chills, developing that classic spreadable texture.

How Long to Prepare Homemade Lemon Curd

Making lemon curd doesn’t take much time, but it does require attention during cooking.

Prep Time: Preparing your ingredients — separating egg yolks, zesting, and juicing lemons — takes about 10 minutes. It’s helpful to have everything measured and ready before you start heating.

Cook Time: Cooking the curd over gentle heat usually takes 10–12 minutes. You’ll need to stir constantly until the mixture thickens. Once done, it takes another 10 minutes to cool slightly before transferring to jars.

Tips for Perfect Lemon Curd

• Use fresh lemons. Bottled lemon juice just won’t give the same brightness or depth of flavor.
• Constant stirring is key. Don’t walk away! Stirring ensures even thickening and prevents scrambled egg bits.
• Cook over low heat or a double boiler. High heat can curdle the eggs quickly.
• Strain the curd. Even if it looks smooth, straining removes zest and any accidental cooked egg for a silky finish.
• Use unsalted butter. This gives you control over the salt content and enhances the creamy texture.

---

Watch Out for These Mistakes While Cooking

• Overcooking: If the curd is left on heat too long or at too high a temperature, it can curdle.
• Skipping the straining step: This can leave bits of zest or egg in the final texture.
• Using metal bowls with reactive surfaces: Lemon is acidic and can react with certain metals, creating off-flavors. Stick with stainless steel or heatproof glass.
• Not cooling properly: Putting hot curd into a sealed jar immediately can create condensation, affecting shelf life.

Frequently Asked Questions

How do I know when lemon curd is done?

It’s done when it coats the back of a spoon and leaves a clear line when you run your finger through it.

Can I use whole eggs instead of just yolks?

Yes, but the texture will be slightly less rich and creamy. Yolks alone give the silkiest finish.

Why did my lemon curd curdle?

Most likely, the heat was too high or you stopped stirring. Always use low heat and stir constantly.

Can I can lemon curd for long-term storage?

Lemon curd is not safe for traditional water bath canning due to its egg content. Stick with refrigeration or freezing.

Is lemon curd gluten-free?

Yes, this recipe contains no gluten and is naturally gluten-free.
