Ninja’s SP351 13-in-1 Toaster Oven Air Fryer solves a common kitchen problem: the space and time trade-off. Instead of juggling multiple appliances, this single unit offers thirteen cooking functions, from air frying and dehydrating to toasting and reheating. Its standout feature is the Dual Heat Technology, which pairs a 500°F cyclonic fan with a 500°F searplate. This combination crisps the top of your food while simultaneously searing the bottom, a tangible upgrade over standard single-source air fryers.

In daily use, this dual system means frozen fries get crispy all over without flipping, and chicken thighs emerge with a genuinely seared skin. The touch controls are intuitive, and the flip-away door is a small but meaningful design choice that saves counter space when open. It’s a capable toaster oven, but where it truly excels is as a rapid, high-heat cooking hub for everything from weeknight salmon to reheating pizza without sogginess.

The stainless steel build feels durable, though its full-size footprint requires a dedicated spot on your counter. For a household looking to consolidate appliances and achieve better browning and texture, the SP351 delivers a noticeable performance edge that justifies its presence.
