Break the apricot in half and remove the pit. If they are a little firm you can use a small knife to cut around the fruit and then remove the pit.
Place the halves on a baking sheet lined with parchment paper or a baking mat. This makes getting the apricots off of the sheet much easier.
Freeze overnight.
Then next day, remove the pan from the freezer and place the frozen apricots in a zipper-topped freezer bag. Close the bag securely and store in the freezer until you are ready to use.
Notes
Frozen apricots are wonderful to use in smoothies, fruit leather, and jam.
You can also let them thaw a few hours and eat them while they are still slushy and partially frozen as a side to a meal.
You don't need a certain quantity of apricots for this method. You can freeze as few or as many as you have on hand to preserve.
Stock up when apricots are in-season at your local orchard, grocery store, or farmers' market to get the best price on this fruit.
