In my opinion the OLIXIS 6.34QT is the one to beat for reheating, because its window lets you watch leftovers crisp up without pulling the basket out and losing heat. Here's how four reheat-friendly options compare, and which one fits the way you actually cook.
• OLIXIS 6.34QT — best for everyday leftover duty; pick this if you want a see-through window, a 180–400°F range in 5°F steps, and a 6.34-quart basket that's dishwasher-safe.
• KINSING Air Fryer — best for big-batch reheating; pick this if you need 7.5 quarts of capacity and a wide 160–450°F range with eight presets.
• HealSmart 6.34 — best for a clean white countertop look; pick this if you want stainless steel construction, 8 one-touch presets, and a 1–90 minute timer.
• Kichvoe Air Fryer Rack — best for stacking more food at once; pick this if you already own an air fryer and want to add a second layer for dehydrating or roasting.
This is a 6.34-quart basket-style air fryer with a stainless steel exterior and a grey finish. The number that matters for reheating is the temperature range: 180–400°F, adjustable in 5°F increments. That granularity is genuinely useful, because reheating is not a one-temperature job. Cold pizza wants a moderate, gentle blast to re-crisp the crust without drying the cheese. Fried chicken wants a bit more heat to bring the coating back to life. A 5°F step means you can actually dial in the middle ground instead of picking between two coarse settings.
The built-in window is the feature I'd point a reheater toward first. Reheating is a short, high-stakes process — a couple of minutes too long and yesterday's dinner turns to cardboard. Being able to glance through the glass and see whether the crust has gone golden means fewer basket pulls, and every pull dumps heat out of the chamber and stretches the total time. The 1–90 minute timer covers everything from a 3-minute slice reheat to a long dehydrate session.
Eight presets cover fries, chicken, steak and more, and there's a dedicated reheat use case in the listing alongside bake and dehydrate. For a beginner, that means pressing a button rather than guessing. Cleanup matters here too: the nonstick basket is dishwasher-safe, which is the difference between reheating dinner on a Tuesday and reheating dinner on a Tuesday and hand-scrubbing a greasy basket. Overheat protection and auto-shutoff round out the safety side.
The trade-off is the capacity. At 6.34 quarts it's a solid mid-size, but if you're reheating for four or five people at once — a whole tray of roasted vegetables plus a protein — you'll be doing it in batches. At 1500 watts it's not the most powerful unit in this group either, so dense, wet leftovers will need a little patience. In my opinion that's an easy trade for the window and the fine temperature control. This is the pick for someone reheating two to three portions at a time who wants to see what's happening.
KINSING Air Fryer
The KINSING is the big one: 7.5 quarts, a full metal body in silver, and an oversized visual window. If your idea of reheating is "the whole tray of last night's sheet-pan dinner goes back in at once," this capacity is the reason to pick it. Fourteen pounds of appliance tells you it's built as a countertop fixture rather than something you tuck in a cupboard.
Eight presets span air fry, roast, broil, bake, dehydrate, frozen, proof bread, keep warm and reheat. There's also a Tender Grill Mode aimed at locking moisture into meats, which is a sensible thing to reach for when reheating a pork chop or a steak that's already cooked and just needs to come back to temperature without drying out. Both the basket and pan are food-grade nonstick and dishwasher-safe.
The trade-off is the footprint. At roughly 14 by 13 by 14 inches, it takes up real counter space, and 7.5 quarts is more machine than a single person reheating one portion needs. If you live alone or cook for two, you'll be heating a lot of empty air. In my opinion this is the right call for a family kitchen where leftovers show up in volume and the air fryer stays out on the counter.
The HealSmart is the closest sibling to my top pick on paper: same 6.34-quart capacity, same 180–400°F range in 5°F increments, same 1–90 minute timer, same dishwasher-safe nonstick basket, same window. The differences are in the body and the details. This one is stainless steel inside and out with a white finish, and it's rated at 1700 watts in the title with 1500 watts in the spec fields — either way it's a punchy heating element for the size.
For reheating, the window plus the fine temperature steps is the same winning combination: you can watch browning happen and stop it before it becomes burning. The eight one-touch presets include Air Fry, Chicken, Fries and Dehydrate, and the recommended-uses list is unusually broad — roast, bake, reheat, dehydrate, wings, seafood, vegetables, even custard tart. That breadth tells you the presets are meant to be leaned on rather than ignored.
The scratch-resistant stainless shell is a practical detail for a machine you'll wipe down after every greasy reheat, and overheat protection plus automatic shutoff mean you can walk away from a reheat cycle without watching it. Touch controls keep the front panel clean and easy to swipe.
Kichvoe Air Fryer Rack
This one is different in kind. It isn't an air fryer — it's a stainless steel rack measuring 8.07 by 8.07 by 3.46 inches that drops into a compatible basket to add a second cooking level. It's a 1-pack, weighs under five ounces, and the polished surface is finished to reduce sticking so it rinses and wipes down quickly.
Why does a rack belong in a guide about reheating? Because the most common complaint about reheating in an air fryer is capacity. If you're warming a main and a side at the same time, a single-layer basket forces you to choose or to cook in relays. A stackable rack lets you put the drier item — say, breaded strips or roasted vegetables — on the upper level where the circulating air hits it hardest, and the denser item below. It's also the tool for dehydrating fruit and meat, grilling ingredients, and roasting sides.
The rack is rated for high temperature resistance and quick heating, and stainless steel construction means it won't warp or react with food the way a cheap coated rack might. Because it's a passive accessory, there's nothing to plug in and no controls to learn. It's also small enough to store in a drawer, and the listing notes it works as a gift for someone who already cooks with air fryer accessories.
The trade-off is obvious and worth stating plainly: this does nothing on its own. It only helps if you already own an air fryer with a basket wide enough to seat an 8-inch square rack, and it doesn't add heat, power or presets. In my opinion it's the right add-on for someone whose air fryer is already fine but who keeps running out of room — not a substitute for buying one.
We compared the published specifications and features of each option — capacity, temperature range, timer, control type, materials, window, presets and cleaning requirements — and weighed them against the specific job of reheating cooked food. The ranking is our independent editorial opinion, based on what those specs mean in daily use rather than any hands-on testing. No brand paid for placement, and no product was selected on the basis of price or popularity.
can you reheat food in an air fryer
Yes. Reheating is an explicitly listed use for the OLIXIS, the KINSING and the HealSmart, and all three offer adjustable temperature ranges — 180–400°F on the OLIXIS and HealSmart, and 160°F up to 450°F on the KINSING — so you can warm food through without overcooking it. The circulating hot air is what brings back crispness that a microwave can't.
how long can you reheat food in an air fryer
There's no fixed answer, but the timer ranges tell you the working window. The OLIXIS and HealSmart both run a 1–90 minute timer, so short reheats of a few minutes and long dehydrate sessions are both covered. Thin items like a slice of pizza reheat quickly at moderate heat, while dense leftovers need longer at a lower setting.
how can i reheat food in an air fryer
Set a moderate temperature rather than the maximum, place the food in a single layer so air can circulate, and use the window to judge doneness instead of opening the basket repeatedly. On the OLIXIS and HealSmart, the 5°F temperature increments let you fine-tune; on the KINSING, the Tender Grill Mode is the setting aimed at keeping meat moist.
can you reheat food in an air fryer like a microwave
Not identically. An air fryer moves hot air around the food, which re-crisps coatings and crusts, while a microwave heats from the inside using moisture and tends to steam and soften them. The air fryer takes a little longer, but for anything that was crispy the first time — fried chicken, pizza, spring rolls — the result is far closer to fresh.
