can i use my regular pyrex dish inside the ninja foodi pressure cooker to make a cheesecake?

No, you cannot use a regular Pyrex dish inside the Ninja Foodi pressure cooker. Using accessory attachments not recommended or sold by SharkNinja can cause injury. Only accessories designed for this unit, such as the removable cooking pot, Cook & Crisp Basket, reversible rack, and Ninja-branded accessories like the Multi-Purpose Pan or Loaf Pan, are safe to use. Unauthorized cookware risks breakage, poor cooking results, and safety hazards. The cooking pot and its accessories are also not safe for use in a conventional oven, microwave, or on a stovetop.
