Pressing the speed cook button triggers the oven's golden heater for cooking that's three times faster than normal convection.

If you thought cooking couldn't get any faster than the air fryer, Sharp's new high-speed oven may have just upped the ante. 

Until now, air fryers have been our go-to for cooking foods that we'd normally make in the oven or on the stovetop in far less time. Sharp's new $4,000 Celerity High-Speed Oven, which I saw in action last week at the KBIS home show, cuts cooking time even further.

I saw the Celerity in action at KBIS 2026. Here's everything you need to know.

The innovative built-in appliance uses three types of heat to cook a whole chicken in 30 minutes -- about three times faster than a standard convection oven and even faster than an air fryer, which takes roughly 45 minutes to cook a 4-pound bird.

The quick-cook function, which the brand has dubbed the "golden heater," uses traditional true convection combined with microwave rays to penetrate food quickly and deeply, and infrared heat to sizzle and crisp the outer layer.

The Celerity oven is smaller than most and closer to the size of a microwave.

The use of microwave heat accounts for the expedited cooking time, while more traditional convection is meant to prevent food from drying out. Plus, we're told the oven requires almost no preheat time when the golden heater mode is implemented.

In a live demo, the Sharp team members baked cookies that emerged from the oven gooey and golden in 9 minutes. A traditional convection oven would take at least 15 minutes to do the same job. We tasted them, and they were as good as grandma's -- gently crispy on the outside and perfectly soft and melty inside.

Speaking of air fryers, if you prefer that method, this oven offers it, too. In all, the oven has nine manual modes, including air fry, quick cook, microwave, convection bake and roast.

I asked the on-site representative whether they're concerned that home cooks will struggle to adapt recipes to this new form of heat. Because it's an industry-first cooking mode, they said, the oven includes dozens of preloaded cooking programs -- all tested by the company's culinary experts -- to help with the learning curve.

The oven also packs in a range of smart features, many of which are familiar from other modern models. Its "Sensor Cook" tech uses moisture sensors to determine ideal cooking times and temperatures, while a built-in camera lets you monitor your food as it cooks to help prevent burning.

The Celerity is available on Sharp's website now for $4,000.
