Preheat your oven to 400°F (200°C) and grease a 24-cup mini muffin tin with cooking spray.

Wash and grate the zucchinis, then squeeze out excess moisture using a clean kitchen towel.

In a medium bowl, mix together the squeezed zucchini, beaten egg, minced onion, cheddar cheese, breadcrumbs, salt, and pepper until well combined.

Spoon the mixture into the muffin tin, pressing down firmly to form compact shapes.

Bake for 16-18 minutes, or until golden brown and crisp.

Let the Zucchini Tots cool for 5 minutes, then loosen them from the tin for easy removal.

For extra crunch, broil for 2 minutes, watching closely to prevent burning.
