Prep the melon. Slice the honeydew in half, scoop out the seeds, and remove the rind.
Cut into rounds and then into thin half-moons or full rounds, about 1/8 inch thick. Thinner slices mean crisper chips.
Pat dry well. Lay the slices on paper towels or a clean towel. Gently press another towel on top to remove as much surface moisture as possible.
This step is key to crisp chips.
Lightly season. Sprinkle a tiny pinch of salt over the slices. If using, mix sugar with cinnamon or ginger and dust lightly over both sides. Add a few drops of lemon or lime juice to brighten the flavor.
Don’t overdo the liquid.
Air fryer setup. Preheat your air fryer to 300°F (150°C) for 3–5 minutes. Line the basket with a perforated parchment liner to prevent sticking, or lightly mist the basket with oil.
Arrange the slices. Place honeydew pieces in a single layer with space between them. Avoid overlap.
Very lightly mist the tops with oil spray to encourage even browning. Too much oil will make them leathery.
Cook low and slow at first. Air fry at 300°F (150°C) for 10–12 minutes. Flip the slices halfway through.
They should look drier and slightly translucent.
Crisp them up. Reduce moisture further by lowering to 275°F (135°C) if edges are browning too fast, or maintain 300°F if they still look wet. Continue for another 8–12 minutes, flipping once. Aim for dry and lightly golden edges.
Final dry-out phase. If your air fryer has a dehydrate function, switch to 160–180°F (70–80°C) for 10–15 minutes.
If not, keep at 250–275°F (120–135°C) for 5–8 more minutes. You want a firm, crisp texture, not rubbery.
Cool to finish crisping. Transfer immediately to a cooling rack in a single layer. Chips will crisp more as they cool.
Wait 5–10 minutes before tasting for final texture.
Repeat in batches. Keep batches small. Crowding traps steam and makes chips soft.
