Preheat the oven to 225 degrees F (110 degrees C). Line a baking sheet with parchment paper.
Spread banana slices out onto the prepared baking sheet
making sure slices are not touching. Brush with lemon juice.
Bake in the preheated oven for 90 minutes. Check bananas
lifting slices up to separate from the paper once or twice. Continue baking until bananas are dried out
30 to 90 minutes more.
Let bananas cool until crispy
at least 5 minutes.
Recipe Tips
If your bananas are too ripe
they'll be more difficult to slice. Slice into 1/4-centimeter slices if using metric units.If the bananas don't start to go crispy after 5 minutes of cooling time
pop them back into the oven for another 15 minutes.
