Ninja Foodi 11-in-1 Multi Cooker 6L Verdict

Who it fits

The Ninja Foodi OP350ANZ earns its place when pressure-cook-then-crisp meals are a recurring part of your routine and you are willing to store and swap two lids to keep both stages in one appliance.

Its 6L cooking pot, 3.7L Cook & Crisp Plate and TenderCrisp system make it a pressure-and-air-fry multicooker rather than a conventional pressure cooker with a longer mode list. The trade-off is equally clear: pressure cooking and crisping use separate lids.

The OP350 makes the most sense when pressure cooking and crisping belong in the same weekly routine. It is not simply a pressure cooker with an extra setting. The TenderCrisp design is built around pressure-cooking food first and then using the separate crisping lid when a dry finish matters.

Its 6L base pot also keeps the product in a different capacity class from 7.5L and 8L competitors. That can be enough for small-to-medium households while keeping batch expectations realistic. If you frequently cook larger pressure batches, the smaller base pot becomes a more important constraint than the number of functions.

What changes the decision

TenderCrisp matters when you actually use the sequence

The defining workflow is simple: pressure cook, then crisp. Pressure can handle the tenderising or wet-cooking stage, while the crisping lid finishes foods that benefit from dry heat and browning.

If that sequence appears regularly in the meals you make, the OP350 solves a real two-stage job. If you mostly cook soups, stews, rice or other dishes that never need a crisp finish, its main differentiator is likely to sit unused.

The 6L pot sets the capacity trade-off

The OP350 has a 6L cooking pot, and Ninja positions the format for up to four people in the AU record. That is enough for many households, but it gives away two litres of nominal base-pot volume to the Instant Pot Duo Plus 8L.

The choice is therefore not simply “more functions versus fewer”. It is whether 6L already covers your normal pressure-cooking volume well enough for integrated crisping to matter more than extra batch headroom.

Two lids are the ownership compromise

The included pressure-cooking lid and TenderCrisp air-fry lid must be handled and stored separately. That may be a minor inconvenience in a roomy kitchen, or the exact friction you are trying to remove in a small one.

The newer Ninja Foodi SmartLid OL650 sits on the other side of this decision: one SmartLid, a 7.5L base pot and a broader pressure/air-fry/SteamCrisp system. The OP350 remains a sensible choice when its two-lid workflow is acceptable and the larger SmartLid platform is unnecessary.

Function count, power and footprint are supporting considerations

The function set includes pressure cook, air fry, slow cook, steam, bake/roast, sear/sauté, grill, yoghurt, dehydrate, keep warm and sous vide. Those 11 functions add breadth, but pressure plus crisping is what materially distinguishes the machine.

The current official Ninja Australia record specifies 1460W; a lower-priority retailer source previously showed 1450W, so the official value is used. Wattage is not treated as proof that the OP350 cooks faster than a rival.

At 38.5cm wide × 35cm deep × 35cm high and 9.56kg, it deserves a deliberate bench and storage plan, including somewhere for the second lid. Those dimensions are placement facts, not a claim that the OP350 is universally harder to live with than every competitor.

The buyer-feedback card below adds current ownership context without changing the permanent fit around capacity, crisping and lid workflow.

The swappable-lid architecture is the ownership trade-off that should be considered before purchase. It gives the OP350 both pressure and air-fry capability, but one lid must be stored while the other is in use. If you regularly use both modes and have storage space, that can be a fair exchange. If lid handling annoys you, a single-lid platform is structurally better suited.

The ceramic-coated pot should also be treated as a real preference point. It supports an easy-release cooking and serving workflow, but it is not stainless steel. Buyers with a hard stainless-vessel requirement should move to an Instant Pot Duo Crisp or a focused stainless pressure cooker rather than treating coating material as a minor detail after purchase.

Who should choose something else

Consider Instant Pot Duo Plus 8L: Families and meal-preppers who want one appliance to replace several (pressure cooker, slow cooker, rice cooker, yoghurt maker, steriliser, sauté pan) and value fast weeknight cooking over air-frying.

PIQSY conclusion

Choose the OP350 when you will genuinely pressure cook and then crisp, 6L is enough, and two lids are an acceptable trade-off. In that scenario, TenderCrisp consolidates a recurring two-stage workflow rather than merely adding another mode.

Skip it when large-batch pressure cooking is the binding need, crisping would rarely be used, or storing and swapping the second lid undermines the convenience you want. Those are structural fit issues, not small disadvantages.
