If you do not wish to fry the fritters, preheat the oven to 400°F (200°C), line a baking sheet with parchment paper or a silicone baking mat, and lightly spray with olive oil. Spread the patties on the prepared sheet and lightly spray with olive oil. Bake for 20 to 25 minutes, until firm and golden, flipping once halfway through to ensure even cooking.
