I included some great Keto lemon curd dessert recipes below, but it can be used as a topping or as a custard-like filling for many of your favorite low carb recipes. Here are a few of my favorite ways to use this microwave lemon curd:

Top off your favorite Gluten Free Scones with a generous dollop
Use as a topping over Fluffy Pancakes and Homemade Waffles
If you happen to over-bake your Keto Lemon Cookies no worries. Just crumble them up and layer them with lemon curd in a mini parfait dish
Add over the top of Keto Pound Cake and a dollop of homemade whipped cream for an extra decadent dessert or even layer with fresh berries for a trifle

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.

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.

Is Lemon Curd the Same as Lemon Pie Filling?

While they are somewhat similar, lemon pie filling is thickened with cornstarch (which isn't Keto) and typically doesn't contain butter. Lemon curd does use butter and thickens naturally from the lemon juice in the mixture.

How Long Does Lemon Curd Last? Should lemon curd be refrigerated?

Without a doubt, it must be refrigerated. It's best to store it in an airtight jar in the fridge for up to a week or so, or several months in the freezer.

Can you Freeze Lemon Curd?

Absolutely, I actually do it all the time! Sometimes I make a batch, but only need part of it, so I freeze the rest and it thaws perfectly. It's nice to always have a little on hand, in case I need some last minute.

What Does Lemon Curd Taste Like?

Much like the ingredients might suggest, it's SUPER lemony. I like to think of it as a more buttery and creamy version of jam.

Tips to Thicken Lemon Curd

Though this Keto lemon curd recipe is almost impossible to mess up, there are 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. But understand, when lemon curd is still hot it's going to be loose. It begins to thicken as it chills in the fridge.
