To ensure the best results, choose fresh and firm zucchinis. Wash the zucchini thoroughly under cold water and pat them dry.
Slice the zucchini into thin, even pieces. Aim for slices that are about 1/4 to 1/2 inch thick.
Place the sliced zucchini in a large mixing bowl and drizzle with olive oil to lightly coat the slices.
Toss the zucchini to ensure each slice is evenly coated with the oil. Then, toss in the bread crumbs and season with salt and pepper.
Arrange the seasoned zucchini pieces in a single layer inside the air fryer basket. Avoid overcrowding the basket, as this can lead to uneven cooking. If necessary, cook the zucchini in batches.
Air fry the zucchini at 400°F (200°C) for 12-15 minutes, flipping them halfway through the cooking time. I usually just shake the air fryer basket well, so all the pieces move around and don’t stick to the basket or each other.
Notes
The thickness you cut the zucchini to allows it to cook evenly and become crispy without turning mushy.
I like to sprinkle on some grated Parmesan cheese before serving, but this is optional.
