Instructions

• If your zucchini is not already sliced, cut the 1 large zucchini crosswise into 1/4-inch rounds and pat the slices dry with a paper towel.
• Choose your cooking method: for oven — preheat oven to 400°F and line a baking sheet with parchment paper; for air fryer — set the air fryer to 400°F (preheat if your model recommends).
• Arrange the zucchini slices in a single layer on a large plate (for staging) or directly on the lined baking sheet. Work in batches if needed to avoid overlap.
• Assemble the bites: spread the 1/4 cup marinara sauce evenly over the zucchini slices (about 1 teaspoon per slice), top each slice with pieces from the 1/2 cup mini pepperoni and the 1/4 cup sliced black olives, then sprinkle the 1 cup freshly shredded mozzarella over the slices. Evenly sprinkle the 1 teaspoon Italian seasoning and 1 teaspoon red pepper flakes over all the bites.
• Air fryer method: place the assembled zucchini slices in a single layer in the air fryer basket (cook in batches if necessary). Cook at 400°F for 5 minutes, or until the cheese has melted and the edges are lightly browned. Remove and serve immediately.
• Oven method: place the assembled zucchini slices on the prepared baking sheet in a single layer. Bake at 400°F for 8 minutes, then switch to broil and broil 3–4 minutes more until the cheese is golden brown and bubbling (watch closely to avoid burning). Remove and serve immediately.
• Let the bites cool for a minute if needed before serving.
