Key Ingredients

I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.

Fresh Lemon Juice & Zest

Always use fresh lemons for maximum citrus brightness. Fresh juice provides authentic flavor and pleasant tartness.

Egg Yolks

Large egg yolks create structure and a deep golden color. They make the curd exceptionally creamy and rich.

Granulated Powdered Sweetener

Powdered erythritol or monk fruit dissolves smoothly without leaving any gritty texture. It adds clean sweetness without carbs.

Unsalted Butter

Cold unsalted butter emulsifies into the hot liquid easily. It thickens the curd while adding a glossy, luxurious sheen.

How to Make Keto Lemon Curd

I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.

1. Whisk egg yolks, lemon juice, lemon zest, and sweetener together in a small saucepan over medium-low heat for 2 minutes.
2. Cook the mixture continuously while stirring with a silicone whisk for 6 to 8 minutes until it thickens to a custard-like texture.
3. Remove the saucepan from the stove heat immediately once the mixture coats the back of a spoon thick and glossy.
4. Stir cold cubed butter into the warm mixture one piece at a time until completely melted and smooth.
5. Strain the curd through a fine-mesh sieve into a glass jar to catch any bits of cooked egg or heavy zest.

Pro Tip: Keep your stove temperature low to prevent scrambling the egg yolks while whisking.

Common Mistakes to Avoid

• Using bottled lemon juice: Bottled juice lacks vibrant flavor and creates a dull, sour taste.
• Scrambling the eggs: High heat cooks the yolks too fast, so maintain a low temperature constantly.
• Skipping the strainer: Straining ensures an ultra-smooth finish by removing accidentally cooked egg specks.
• Granular sweeteners: Non-powdered sweeteners can leave a crunchy aftertaste once the curd cools down.

Required Equipment

• Silicone Whisk — prevents scratching pans and blends egg yolks smoothly.
• Small Saucepan — distributes heat evenly to prevent premature scorching.
• Fine-Mesh Sieve — removes solid bits to yield a silky finish.
• Glass Mason Jar — preserves freshness safely inside your refrigerator.

Caleb’s Recipe Tips

• Use Room Temperature Eggs: Warm egg yolks blend smoothly into lemon juice without separating.
• Powder Your Sweetener: Blend standard granular sweetener in a high-speed blender first for maximum smoothness.
• Add Pinch of Salt: A micro-pinch of fine sea salt enhances the lemon flavor dramatically.
• Chill Before Serving: Allow the curd to cool in the fridge, as it thickens significantly when cold.

Storage Instructions

• Refrigerator: Store in a sealed airtight glass container for up to 10 days.
• Freezer: Freeze in a freezer-safe container for up to 3 months safely.
• Containers: Glass mason jars work best to avoid flavor transfer.
• Shelf Life: Keep chilled constantly; do not leave at room temperature overnight.
• Reheating: Thaw frozen curd in the fridge overnight and stir well before serving cold.
