Silky, vibrant homemade lemon curd bursting with fresh bright lemon flavor and comes together with just a handful of simple ingredients. Made with fresh lemons, it cooks into a smooth, glossy spread that’s perfectly sweet, tangy, and rich. Use it as a cake filling, swirl it into yogurt, spread it over scones, spoon it into tart shells, or eat it straight from the jar (no judgment).

I am going to be honest and say that I get pretty lazy when I think about making lemon curd, only because zesting and juicing feels tedious. But then, whenever I want to impress with my Limoncello Mascarpone Cake, I get my self to the kitchen only to realize how simple and easy this recipe is, (Juicing the lemons still is the hardest part).

There are a few tiny details one should always keep in mind when making homemade curd, and you can find all the tips and trick in this post.

Whole Eggs vs. Egg Yolks

Most lemon curd recipes call for egg yolks only. This recipe uses a combination of both, because I wanted the texture to be as light and bright as the color and the flavor.

When we use whole eggs, we increase the amount of water in the recipe, giving it a lighter texture and brighter color. It also means that the recipe thickens faster due to the increase of protein that coagulate at a lower temperature (egg whites vs. egg yolks).

Make It

Below are step by step images for a visual guide, and I also included all by tips, tricks and lessons I learned when developing this recipe. The complete recipe is at the bottom of this post in the recipe card.

  • Use room temperature ingredients. The process begins as soon as we start mixing, and a smooth curd depends on proper blending from the start. Room temperature ingredients combine more evenly, preventing separation and ensuring a stable, cohesive mixture.
  • Use a rubber spatula, or a wooden spoon to mix while cooking. Some silver and metal spoons (and whisks) may contain aluminum, that when in touch with eggs and heat can react and give the curd into a yellow-grayish color.
  • Cook the mixture over steady, low heat and stay put while constantly stirring. You want to prevent the eggs from cooking, and curdling.
  • The best way to know if the curd is ready is to test it on the back of a spoon or spatula. Run your finger through the center, if the line stays clear and the curd does not run back together, it’s ready.
  • For a thicker curs: increase the amount of butter by 2-3 tablespoons.
  • The curd might seem thin at first when warm, as it cools it will thicken and set.

Recipes To Use Lemon Curd With

Storing

Store the curd in the refrigerator for up to five days. To freeze, place it in a freezer bag, remove as much air as possible, and freeze for up to twenty weeks. When ready to use, refrigerate overnight.

Homemade Lemon Curd | Four Ingredients

Thick and creamy lemon curd made with fresh lemons, comes together in a few simple steps. Perfect as filling, topping and drizzling on pastries, cakes, cookies and more.
Prep Time 15 minutes
Servings 1 Cup

Ingredients

  • 1/2 Cup (100g) Sugar
  • 1 Tablespoon Fresh lemon zest (from about 2 medium lemons)
  • 1 Large Egg at room temperature
  • 2 Large Egg yolks at room temperature
  • 1/2 Cup (120ml) Fresh squeezed lemon juice
  • 6 Tablespoons (85g) Unsalted butter cut into 1/4-inch pieces

Instructions

  • Tun the lemon zest into the sugar (100g).
  • Mix in the egg (1) and egg yolks (2) into the sugar.
  • Pour in the lemon juice.
  • Pour the mixture into a medium saucepan and cook over medium-low heat, while constantly stirring until the mixture has thickened and coats the wooden spoon you are using.
  • Run the curd through a sieve over a bowl.
  • Add the butter (85g) and gently stir until the butter is completely melted.
  • Allow the curd to cool, then use or refrigerate for up to five days.

Notes

  • Use vegan butter to make it dairy free.
  • Store in the refrigerator for up to five days. To freeze, place in an airtight container or a freeze bag for up to eight weeks. When ready to use, place in the refrigerator the night before.
  • To establish the curd’s readiness, swipe the back of a spoon dipped into it with your finger. It’s done when it coats the spoon thickly and exhibits a creamy consistency.
  • Prevent the curd from boiling over low heat, which may cause the eggs to curdle. Use a double boiler to avoid direct heat and take an additional precaution to ensure the recipe’s success.
  • If desired, increase the quantity of butter in the recipe to achieve a thicker curd.
