Step‑by‑Step Instructions for Keto Lemon Curd

Step 1: Prep Lemons
Begin by washing and zesting 4-5 medium lemons, aiming for about 1-2 tablespoons of zest. Cut the lemons in half and juice them to yield roughly 1/2 cup of fresh lemon juice. Strain the juice through a fine-mesh sieve to remove any seeds and pulp, ensuring a silky-smooth base for your Keto Lemon Curd.

Step 2: Whisk Base
In a heavy-bottomed saucepan, combine four large eggs, 2/3 to 3/4 cup of powdered erythritol (or allulose), your freshly strained lemon juice, lemon zest, and a pinch of salt. Whisk these ingredients together thoroughly until smooth and well combined. This will form the rich and vibrant foundation of your keto lemon curd, so take your time to ensure it’s lump-free.

Step 3: Cook Mixture
Place the saucepan over low to medium-low heat and whisk constantly, allowing the mixture to warm gradually. Continue this gentle stirring for about 7-12 minutes until the curd thickens enough to coat the back of a spoon—a key visual indicator for doneness. Be careful not to let it boil, as this could affect the delicate flavor.

Step 4: Incorporate Butter
Once the mixture has thickened, remove the saucepan from the heat. Add six tablespoons of cut-up unsalted butter into the hot lemon curd, whisking it in until completely melted and smooth. If you like, incorporate a 1/2 teaspoon of vanilla extract at this stage to deepen the flavor.

Step 5: Strain Curd
To achieve an ultra-smooth texture, immediately pour the cooked curd through a fine-mesh sieve into a clean bowl or jar. This straining step will catch any lumps and bits, ensuring your Keto Lemon Curd is as velvety as possible.

Step 6: Cool and Set
Cover the surface of the warm lemon curd with a piece of parchment paper to prevent a skin from forming as it cools. Allow your curd to chill in the refrigerator for at least 2 hours, letting it thicken further. Once fully cooled, your Keto Lemon Curd is ready to be enjoyed in various delightful ways!

How to Store and Freeze Keto Lemon Curd

Fridge: Store your keto lemon curd in a sealed glass jar for up to 1 week. Make sure the lid is tightly closed to maintain freshness and prevent odors from other foods.

Freezer: For longer storage, freeze the lemon curd in small portions in airtight containers or ice cube trays for up to 3 months. Thaw in the fridge overnight before using.

Reheating: If the curd thickens after freezing, gently reheat it in a saucepan over low heat while stirring until it reaches the desired consistency. This ensures your keto lemon curd is smooth and creamy again.

Labeling: Always label your jars or containers with the date of preparation to keep track of freshness, allowing you to enjoy your delightful keto lemon curd for as long as possible!

Make Ahead Options

These Keto Lemon Curd preparations are perfect for busy home cooks looking to save time! You can prepare the entire keto lemon curd mixture up to 3 days ahead of time. Simply follow the initial cooking instructions, allow the curd to cool completely, and then store it in an airtight container in the refrigerator. To ensure the best texture, place a piece of parchment directly on the surface of the curd to prevent a skin from forming. When you’re ready to use it, simply give the curd a good stir, and it will be just as delicious as when freshly made. Enjoy the convenience of having this zesty delight ready for your favorite snacks or desserts!

Keto Lemon Curd Recipe FAQs

What type of lemons should I use for the best flavor?
Absolutely! For the best flavor, I recommend using fresh, plump, and organic lemons. Look for lemons that are bright yellow without any dark spots or blemishes. You’ll need 4-5 medium lemons to yield about 1/2 cup of juice and 1-2 tablespoons of zest, ensuring that vibrant, tangy flavor shines through in your keto lemon curd.

How should I store my keto lemon curd?
To keep your delicious keto lemon curd fresh, store it in a sealed glass jar in the refrigerator for up to 1 week. Make sure to close the lid tightly to prevent odors from other foods infiltrating your curd. If you want to enjoy it longer, it can also be frozen!

Can I freeze keto lemon curd, and if so, how?
Very! Freezing keto lemon curd is a fantastic option. Start by pouring the curd into an airtight container or ice cube trays for small portions. It will last for up to 3 months in the freezer. When you’re ready to use it, simply thaw it in the fridge overnight. If it thickens too much after freezing, gently reheat it on low heat in a saucepan, stirring until you reach the desired consistency.

What should I do if my lemon curd turns out too thick or lumpy?
If you find your keto lemon curd has thickened more than you’d like or has developed lumps, don’t worry! Simply returning it to a saucepan over low heat can help. Add a splash of lemon juice or a tiny bit of water while stirring continuously until it smooths out. The key is to heat it gently to avoid cooking the eggs further, which can change the flavor.

Does keto lemon curd have any dietary restrictions I should consider?
The beauty of keto lemon curd is its sugar-free nature, making it suitable for those following low-carb diets. However, it’s essential to consider any allergies. If preparing for others, ensure that there are no egg allergies, as the recipe uses four large eggs that contribute both richness and texture. It’s always good to ask before serving!
