*Exact measurements are listed in the recipe card below.
How to Make 5 Minute Low Carb Lemon Curd
Add the eggs into a large mixing bowl and whisk.
Mix in the Swerve for 2 minutes or until well combined.
Then add the remaining ingredients and mix well. Cook in the microwave for 1 minutes, remove and whisk.
Place back in the microwave to cook for another minute, remove and whisk. Repeat the process 3 more times, for a total of 5 minutes.
You'll notice it thickens a little more each time. By the 5th time it's perfect curd consistency.
Allow to cool at room temperature for 10-15 minutes, then store leftovers in the fridge for up to a week, or in the freezer in an air tight container for up to couple of months.
Are Lemons Keto?
Absolutely! They're low in carbs and high in fiber. So go ahead and flavor your water or unsweetened tea with the juice of a lemon, or make your favorite Keto lemon dessert.
Not only are they low in carbs, the nutrients in lemons are reportedly linked to being a potential aid in weight loss and digestive issues. They're an excellent source of vitamin C and have other health benefits that you can read more about in this article.
So, How Many Carbs in Lemons?
There's only 1.4 gram of carbs in lemon juice for 1 tablespoon. This entire recipe uses only ½ cup, making lemon juice a great low carb flavoring option.
How to Thicken Lemon Curd
Though this Keto lemon curd recipe is almost impossible to mess up, there're a couple of things that can happen that causes lemon curd to be runny. The key to making it thick is heating it enough during the cooking phase. The eggs and lemon work together when heated to make a custard like texture, so make sure to cook it for all of the 5 minutes.
Depending on your microwave, you may have to cook it for another 30 seconds and whisk again. But understand, when lemon curd is still hot it's going to be loose. It begins to thicken as it chills in the fridge.
You can use this lemon curd to fill my Lemon Meringue Cupcakes...
You can also use it in my Lemon Mascarpone Tart!
Or my Mini Lemon Curd Tarts...

RECIPE NOTES
Yum! Very excited to make these for my Mom. They are her favourites. Can you suggest a substitute for the oat fiber? Thanks.
Looks go good!! Cant wait to make your lemon mascarpone dessert with this!!! Thank you!!
Looks great, hope you enjoy!
I left a comment earlier about the consistency of this after cooking it for 3 minutes. Then after I posted it I saw my LEMON JUICE sitting on the counter. After I added it, it was PERFECT. I LOVE this and will definitely be using this in several dishes!.
Changing my rating to a 5 star!!!
Oh wow, yeah that would definitely change the consistency a bit. Glad to hear that you love it now 🙂
I only use Swerve Confection sweetener and I get the crystals every time I put it in the refrigerator. I have tried other recipes with the same results. Its good till I put it in the fridge.
My lemon five minute curd was like curd when done not creamy like picture. Not sure if because I didn't put enough lemon juice or not. What do I do with it? I don't like the strong flavor do didn't put quite as much in. 1/3 cup
Yep, followed it to the T. So you think it could maybe be the zest?
It's certainly possible because you will have little chunks of zest in the curd, rather than the sweetener crystalizing.
Amazing recipe!! I just have one question, when I pulled it out of the fridge to use again, there were little sugar crystals in it, is that normal?
There really shouldn't be if you are using Swerve confectioners. If you use granular, you will get those crystals.
I made this yesterday using powdered Swerve. After refrigerating overnight, I (sadly) have the same problem. The flavor is great though. 8/20/20
I could eat this all the time. Made spoon bread and drizzle some on it when I went to eat it
Awesome! I love it too 🙂
This is great, I love it.
Awesome, glad you love it!
Delicious
Hello and thank you for this. Just made it and its tasting amazing. I did use granual sweetener so it is a bit gritty but it doesnt spoil it. Next time i will gtind it before hand. I am going to greeze in ice tray so can take a little at a time.
Yes, granular will do that, which is why I prefer using confectioners. Love the ice cube tray idea, thanks for sharing!
I've been on a strict 20 gram low carb diet for a 1 1/2 years due to medical condition. My husband had to start low carb for his sugar so now I can afford to cook meals. I'm just learning how to cook this way and can you please tell me what lemon zest is and how long can I freeze the curd? Thank you so much for your recipes and following my Heavenly Father and sharing Christ with the world. May God bless and keep you and yours always.
Hi Ronda,
Lemon zest is just the outer rind of the lemon. You take a microplane and gently scrape just the yellow part (not the white pith) off the lemon. It has tremendous flavor, so I use it in this curd, and many other recipes. You can freeze the curd for at least a few months, in an airtight container. Thank for your kind words and blessings from the Lord, I appreciate it 🙂
I love the flavor, but why does the erythritol test gritty in this recipe.
Hi Liz,
Did you use the Swerve confectioners? Regular granular erythritol will get gritty, that's why I use the confectioners it tends to stay smooth.
I don't understand the serving size, it says 12 servings? But it makes 1.5 cups., so a serving is one ounce?
1 servings is about 2 tablespoons.
I’m in uk are the measurements different for uk
Hi Julie,
You can click on the "metric" link in the recipe card and it will convert all the measurements for you.
This is the best stuff ever!!! I made one mistake. I didn’t double it!
So easy to make and just luscious.
Hi Teresa,
Glad to hear you liked it! It's amazing how good it tastes for only cooking 5 minutes in a microwave! Enjoy 🙂
