Ninja Flip SP151: What Is the Basket Made Of?
The Ninja Flip SP151 is a flip-up countertop oven with “Stainless” in its name. We couldn’t confirm what its mesh basket is made of or whether it is coated. Ninja’s own papers don’t say, so ask Ninja before you buy.

The short answer
We couldn’t confirm the Ninja Flip’s basket. Ninja’s list names aluminum and stainless steel for this oven series but doesn’t say which part is which. Ninja’s SP151 page says “Material: stainless steel” for the whole product, not the basket. A search result says Ninja’s FAQ calls the basket not nonstick, but not nonstick doesn’t mean uncoated.
What's on this page
What is the basket made of?
We couldn’t find out. Ninja’s SP151 page says “Material: stainless steel” and “Dishwasher Safe: No” for the whole product. That doesn’t name the basket. A parts page for the basket says only “Mesh basket designed for excellent airflow”.
We would choose the Flip for its flip-up shape, not for what is inside, because nothing we read says what is inside.
Ninja Flip SP151
Ninja’s page says “stainless steel” for the whole product, but not what the basket is.
Listed for the flip-up design. We couldn’t confirm what its basket is made of.
Good for families who want a flip-up countertop oven and are fine with the basket question staying open.
Coating: We couldn’t confirm
- Ninja’s chemical list for this series shows no PTFE on that line
- The list doesn’t say if the mesh basket is coated
- Ninja’s page says “stainless steel” for the whole product, not the basket
- The manual copy we read has no model number and says nothing on materials

What does Ninja’s list say?
SharkNinja, the company behind Ninja, publishes a list for California. For this oven series it names aluminum and stainless steel, and PTFE isn’t on that line. That is more than many brands share.
It doesn’t say which part uses which, and it doesn’t say whether the basket is coated. It is dated 2025, so a newer version could differ. We matched the SP151 to this series by its number, so ask Ninja if that matters to you.
Is it right for me?
In its favor
- You want a flip-up countertop oven
- You’re willing to ask Ninja about the basket
- You like a brand that publishes a list
Against it
- You want a statement about the basket before you buy
- You want to know what the inner walls are
What should I ask Ninja?
Give your model number from the label and ask:
- What metal is the air fry basket, and is it coated?
- What about the sheet pan and wire rack?
- Are the inside walls coated, and with what?
- Does that apply to units made now?

Common questions
What is the Ninja Flip air fryer basket made of?
We couldn’t confirm it. A parts page describes a mesh basket and names no material. Ninja’s SP151 page says “Material: stainless steel” for the whole product. Ask Ninja in writing.
Is the Ninja Flip basket nonstick?
We only saw this in a search result. Ninja’s FAQ answers “Is the air fry basket nonstick?” with “No”. We couldn’t open that page. Not nonstick doesn’t mean uncoated.
Does the Ninja Flip have PTFE?
PTFE, the slick nonstick coating best known as Teflon, is not on the line for this series in Ninja’s list. The list is dated 2025 and doesn’t cover every part, so it isn’t proof that nothing is coated.
