Which Ninja models does this basket fit?

It fits the DoubleStack XL air fryers SL401, SL451, SL401Q and SL451C. It does not fit DualZone, Foodi or other Ninja air fryer lines.

Is this a whole drawer or just the basket?

It is the basket that sits inside the drawer. The outer drawer, handle and crisper plate are not included, so order those separately if they are what you need.

Can I put it in the dishwasher?

Yes, the nonstick basket is dishwasher safe. Hand washing with a soft sponge keeps the coating in better shape over time.

Will my old recipes and timings still work?

Yes. It matches the capacity and shape of the original DoubleStack XL basket, so existing recipes and cook times carry over.

Does it come with a crisper plate?

No. The basket is sold on its own, so keep the crisper plate from your original drawer or buy one separately.

Is it worth buying as a spare?

If you cook in batches or your original basket is scratched or damaged, a second basket saves washing between rounds. If your current basket is fine, there is little to gain.
