Preheat oven to 200 ℉ or the lowest setting available.
Thinly slice your strawberries about ⅛ inch thick. You can slice them thicker, but don’t slice them any thinner or they’ll burn and get too crispy when baking.
Add the sliced strawberries to a baking sheet lined with parchment or silicone baking mat (do not use wax paper, a plain baking sheet or aluminum foil).
Bake in pre-heated oven for about 2 hours. If you want, you can flip them over the last 30-45 minutes.
Once they’re to your desired crisp-ness you can remove from the oven and let them cool completely.
Gently peel them from the parchment paper and they're ready to use.
Notes
The more evenly the berries are sliced, the more evenly they’ll cook. You can also use an egg slicer for perfectly even slices.
Be sure to bake these on parchment paper or a silicone baking mat. Anything else such as a plain baking sheet, wax paper, or aluminum foil will cause the strawberries to stick.
If you want a more chewy dried strawberry, you can slice them a little thicker but they might take a little longer to cook.
These strawberries will last a couple of weeks in an airtight container at room temperature.
