Rinse and drain your can of chickpeas, making sure to dry them well. (If using home-cooked chickpeas, you'll need 1 and a 1/2 cups.) When done, set aside.
On a baking sheet lined with parchment paper, bake falafels in the oven for about 20-30 minutes (may vary depending on the size of your falafels).
When done, let cool completely. This is a very important step - the falafel will be very fragile when they're first out of the oven.
