Begin by washing the zucchini thoroughly. Trim the ends.
Slice the zucchini into lengths, about 0.5 cm (0.2 inches) thick. Ensure they are not too thick or too thin for even cooking.
Lay the zucchini slices on a clean surface or baking sheet. Generously sprinkle them with salt and let them sit for about 10 minutes. This process draws out excess moisture, which is key for crispiness.
After salting, use paper towels to thoroughly pat dry each zucchini slice. Remove as much moisture as possible.
Lightly sprinkle about 1 teaspoon of corn starch on both sides of the dried zucchini slices. Use your fingers to spread it evenly all over. You don't need a thick layer.
