Slice the strawberries into ¼ inch pieces. There are two different ways to do this - I have shown them in options a and b. I slice the tops off (save them - see below), then either option a) slice them lengthwise, or option b) slice them through the middle in circles.
Lay the strawberries out on the tray of a dehydrator, ideally not touching each other so that they can dry fully on all sides. Optionally, you can drizzle them with a little lemon juice or sprinkle a little sugar on them, but we don't think it is needed.
Place the trays in the dehydrator, then set the temperature on the dehydrator to the fruit setting, on mine it is 135°F. If you are using a smaller dehydrator that doesn't have a temperature control, just turn it on.
Set a timer for 6 hours, but check the fruit after a few (maybe 3 or 4) hours to make sure that everything is drying out as expected. It should take between 6 and 10 hours to try out fully - if cut evenly, they should all be done in 8 hours.
Totally optional, but I like to also dehydrate the tops of the strawberries and feed them our dog as treats. Sometimes she acts like she likes them. You can also dry them out and save them to steep and make strawberry tea!
Dehydrated strawberries are ready when they are chewy with a little bit of bend to them - kind of like the pliable but tearable texture of jerky.
The final step is to "condition" your strawberries. If you put them into an airtight container when they are warm and fresh out of the dehydrator, you will trap moisture and they will likely grow mold or get soft.
Let the strawberries come to room temperature, then place them in an airtight container. I like to use glass jars over plastic because I have noticed that things like dried fruit, crackers, chips, etc. will start to absorb the taste of plastic after a while.
For about 7 days, check on your strawberries daily, shaking the jar around and checking for moisture. Once you are certain that the strawberries are completely dry, place a desiccant pack in the jar with them and place them in a dry place that doesn't get really hot.
Enjoy when you want something sweet!
