How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the simplest drop-in crisper plate for a small air fryer basket and you mainly cook straight batches of onion rings, choose RASTKY 6.1; if you need a handled grill plate that fits a 2QT mini air fryer with rubber bumpers for stability and dishwasher-safe cleanup, choose KoiLykke Air Fryer Grill.
• RASTKY 6.1 — biggest strength: a perforated iron plate with a double layer non-stick coating and a rubber sleeve that protects the inner pot body from scratches.
• RASTKY 6.1 — biggest trade-off: it is a bare 6.1 inch round plate, machine washable but with a coating warning against rough scrubbers, and it has no separate bumpers or stabilizing feet in the box.
• KoiLykke Air Fryer Grill — biggest strength: a handled, enameled non-stick plate sized at 6 x 5.6 inches for 2QT mini fryers, shipped with four rubber bumpers to keep it steady and dishwasher safe for fast cleanup.
• KoiLykke Air Fryer Grill — biggest trade-off: it is built around a specific small basket size, so it is not the plate for a bigger round basket that wants a full 6.1 inch disc.
• Who each pick is for: RASTKY 6.1 for the cook with a round 6.1 inch basket who wants one plain, protective crisper plate; KoiLykke Air Fryer Grill for the 2QT mini air fryer owner who wants a handled plate plus bumpers for airflow and stability.
RASTKY 6.1 is a replacement crisper plate first, and that is exactly how it behaves. The perforated design is the whole point: air moves up through the holes and around the food, so onion rings, French fries, pizza slices, chicken and steak get even heat instead of sitting in a puddle on a solid surface. If your onion rings have been coming out pale on the bottom, a perforated plate is the low-effort fix, because the hot air can actually reach the underside instead of being blocked.
The build is iron with a double layer non-stick coating, and the included rubber sleeve is the detail I appreciate most. It sits between the plate and the inner pot body, so you are not grinding metal against metal every time you slide the plate in or lift it out. The handle makes removal easy mid-cook, which matters when you want to shake or flip onion rings halfway through without burning your fingers or digging around with tongs.
KoiLykke Air Fryer Grill: Who It's For
KoiLykke Air Fryer Grill is aimed at a narrower, more specific machine: the 2QT mini air fryer and baskets that take a 5.6 x 5.6 inch crisper plate. The headline difference is the shape and the kit. You get one grill plate measuring 6 x 5.6 inches plus four rubber bumpers, and those bumpers are the quiet hero here. They hold the plate steady inside the basket while cooking, which keeps it from sliding around when you shake the basket, and they lift the plate slightly so air can move underneath for crisper results.
The plate itself has a built-in handle, so lifting it out of the basket needs no tools — useful when you want to pull onion rings, chicken wings or fries and get straight to the next batch. The enameled non-stick coating with a double layer spray is the cleanup story: dishwasher safe, and easy to wipe down if you would rather not run a cycle. The listed cooking range is broad — French fries, onion rings, chicken wings, steak, vegetables, pizza and dehydrated snacks — and the removable design means you can cook one food, lift the plate, and start the next without scrubbing the whole basket in between.
Who should buy it: 2QT mini air fryer owners who want a handled plate with bumpers for stability, proper airflow and dishwasher-safe cleaning. Who should skip it: anyone whose basket wants a full round 6.1 inch plate, or who prefers a rubber sleeve protecting the pot wall instead of bumpers under the plate. This is a fit-specific accessory, and fit is the one thing you cannot compromise on with air fryer plates.
Side-by-Side: Which Should You Choose?
• Best for round 6.1 inch baskets → RASTKY 6.1, which matches that diameter exactly at 15.5 cm.
• Best for 2QT mini air fryers → KoiLykke Air Fryer Grill, sized 6 x 5.6 inches for that smaller basket footprint.
• Best for stability while shaking → KoiLykke Air Fryer Grill, because the four rubber bumpers hold the plate steady and keep air flowing underneath.
• Best for dishwasher convenience → KoiLykke Air Fryer Grill, which is explicitly dishwasher safe; RASTKY 6.1 is machine washable but its coating should not meet rough scrubbers.
• Best for onion rings specifically → both work, but RASTKY 6.1's perforated round plate spreads a full basket of rings evenly, while KoiLykke's handled plate makes it easier to lift a load out and reload.
• Best for low-fuss ownership → RASTKY 6.1, since there is one plate and one sleeve to keep track of, with no bumpers to lose.
• Best for multi-batch cooking → KoiLykke Air Fryer Grill, where you lift the plate, cook the next food, and wash everything together at the end.
In my opinion, the deciding factor here is your basket, not the food. If your air fryer takes a round 6.1 inch plate, I would buy the RASTKY 6.1 — the perforated design, double layer coating and rubber sleeve cover everything an onion-ring cook needs, with nothing extra to misplace. If you own a 2QT mini air fryer with a 5.6 inch basket, I would buy the KoiLykke Air Fryer Grill instead, because the handled plate and four bumpers are built for exactly that machine, and the dishwasher-safe enameled coating makes cleanup genuinely easier. Neither is a compromise pick; they are two correct answers to two different basket sizes.
how to air fry onion rings
Spread the rings in a single layer on the crisper plate so hot air can pass through the perforations and around each ring. Leave a little space between them, then shake or flip halfway through so both sides brown evenly.
how to air fry onion rings frozen
Put the frozen rings straight onto the plate in one layer — no thawing needed. Give them a shake partway through so they do not stick together, and add a minute or two if your basket is crowded, since frozen rings release moisture that slows crisping.
how to air fry onion rings in oven
An air fryer crisper plate is not an oven rack, so use a perforated tray or a wire rack set over a baking sheet if you are oven-baking instead. Keep the rings in a single layer and flip once; a rack does the same job the perforated plate does, letting heat reach the underside.
No, but it helps. A plate like these lifts food off the basket base so air circulates underneath, which is why onion rings brown on both sides instead of steaming on the bottom. The KoiLykke bumpers and the RASTKY sleeve both exist to keep that plate sitting correctly while you cook.
If you are weighing these two, check the current price on Amazon before you commit — but check your basket size first, because that is what actually decides this one.
