For extra crispiness, make sure there is some space between each zucchini piece on the wire rack while baking.
These are best fresh, but you can store leftovers in the fridge for up to 3 days. Reheat in a toaster oven or air fryer to bring back some of the crispiness.
You can air fry at 400°F for 10–12 minutes, flipping halfway through. Keep an eye on them toward the end to make sure the cheese doesn’t burn.
Freshly grated Parmesan melts and crisps up much better than pre-shredded, which often contains anti-caking agents that prevent it from sticking and browning as nicely.
Make sure your zucchini is firm and not too large, as small to medium-sized, younger zucchinis will yield the best texture and flavor.
While garlic aioli is the perfect pairing, you can also try marinara sauce, sriracha mayo, or homemade ranch dressing for dipping!
