Preheat the oven to 150° or the lowest your oven will go, making sure it’s below 200°. Line your baking sheet with a silpat and set aside.
In the blender add the strawberries, lemon juice and sugar. Blend until you have a smooth puree. Pour the puree onto the baking sheet and smooth using a knife or an offset spatula. Tapping the pan on the counter a few times can help get it nice and even.
Bake for 6-8 hours, or until the leather is no longer tacky. Remove from the oven and allow to cool completely before using a pizza cutter to cut into strips for fruit roll ups or into rectangles for pieces of fruit leather. If you would like to roll it, cut a strip of parchment paper to roll up with it so it does not stick to itself.
