Freezing Strawberries

I have been seeing strawberries in the grocery store since mid-winter. Before we know it, strawberries will begin bearing in our area. When strawberries are ripe, we get many calls asking for directions to freeze strawberries. So, if you need directions and AnswerLine is not open now, read on.

Freezing or any type of preserving of food never improves the quality of the food. So choose only fully ripe and firm berries. Look for a nice deep red color on the berries. Do not freeze anything that is immature, green, or damaged. Always wash produce well before freezing. Remove the caps from the berries.

Often, the recommendation for freezing fruit includes using a sugar syrup. The reason for this is to preserve the color and texture of the food. We do not use syrups to make the berries sweeter. There are several different syrups to choose. You will want to choose the one that best fits how you will use the strawberries once you have thawed them. Whole berries are best to freeze in syrup.


Syrups to use when freezing fruit

Type of syrup Percent syrup Cups of sugar Cups of water Yield of syrup
Very Light




4 ½ cups




4 ¾ cups


1 ¾


5 cups


2 ¾


5 1/3 cups
Very Heavy




6 cups


You can also freeze whole berries in a sugar pack. Simply add ¾ cup of sugar to a quart of strawberries. Stir the mixture until the sugar dissolves or you can let it stand for 15 minutes. Place into a container but allow enough room so the strawberries can expand in the freezer without pushing the lid off.

If you prefer sliced berries, use the sugar pack after you have prepared and sliced the berries. Stir until the sugar dissolves or let them sit for 15 minutes. Freeze and enjoy.
