Preheat the oven to 225°F (110°C). Place parchment paper on a baking tray.
Organize the banana slices on the ready baking sheet, ensuring the slices don’t contact. Brush with lemon juice.
Bake within the preheated oven for 90 minutes. Look at the banana, lifting the slices as much as separate them from the leaf a few times. Proceed baking till bananas are dry, one other 30 to 90 minutes.
Let bananas cool till crisp, at the least 5 minutes.
If the banana is just too ripe, will probably be tough to slice it. Reduce into 1/4-inch slices if utilizing metric items.
If the bananas do not begin to flip crispy after 5 minutes of cooling time, set them again for one more quarter-hour.
