Can You Freeze Lemon Bars?

Lemon bars are delicious. They are probably one of the best lemon desserts out there. They have a crumbly exterior made out of shortbread and a lemon-flavored custard inside. If you’re going to make them, you don’t want to go to all the effort just to make a few bars. It is better to make them in bulk. However, can you freeze the ones that you don’t eat that day? The answer is yes, but you have to follow stringent guidelines because they are delicate and might react badly to freezing. However, we are going to tell you how to freeze them so that they are delicate and light.

Freezing Lemon Bars

Freezing temperatures can cause freezer burn which means that your food will dry out. You don’t want this to happen with your lemon bars as they are delicate and creamy. To avoid this, you should follow our instructions, and then you will get lemon bars that taste as good as fresh ones. 

You may want to make lemon bars solely for freezing (see also Can You Freeze Lemons?) or you may just want to freeze ones that are leftover. Whichever it is, the instructions are exactly the same. 

Don’t leave the lemon bars at room temperature for too long before freezing. This can make them dry out. However, if you have just made them, leave them to cool at room temperature before freezing. If you put warm lemon bars in the freezer, it will put the temperature up in the freezer and that can mean that food will spoil.

The first thing to do is to cut the lemon bars into portions. The best thing to do is to cut them into single-serve slices so that you can thaw just as many as you need. Once you have done this, wrap each bar in plastic wrap. It is best to wrap it twice so that it is secure. Check that there are no bits exposed as this can cause freezer burn, but with two layers of plastic wrap, you should be alright. Next place them in a resealable bag or an airtight plastic container. Try and make sure that there isn’t excess air in either the bag or the container as this is what causes freezer burn. 

It is a good idea to put a label on the bag or container saying when you froze the lemon bars. If you freeze a lot of items it is easy to forget when you put them in the freezer. You don’t want your lemon bars to sit in the freezer for months on end as their flavor will deteriorate. 

Shelf Life of Lemon Bars in the Freezer

Lemon bars can keep for up to six months in the freezer (see also Freezing Lemon Tarts). However, they are best eaten earlier than this, perhaps up to one month. They won’t go off, but the flavor could deteriorate and they may dry out. 

Thawing Lemon Bars

It’s really easy to thaw lemon bars. Just take out as many as you want and put them in the fridge overnight. As with all food, don’t refreeze them as that can cause bacteria to form.

Reheating Lemon Bars

It’s not necessary to reheat lemon bars once they have thawed as they taste best slightly cold. However, you can warm them up if you wish. Just put them on a parchment-lined baking dish and heat in the oven for a few minutes at 350 degrees Fahrenheit.


Yes, you can freeze lemon bars, but you need to keep them moist. If you follow the tips we have given you, you will be able to have perfect lemon bars whenever you want.
