Open Frying


So, what is open frying?

Open frying submerges food in an open vat of hot oil, a cooking method commonly used for items that should be crispy when done — like fries, for example.

Why choose an open fryer?

Kitchens utilize open fryers instead of pressure fryers for a variety of menu items, including foods that float while cooking. There are lots of reasons you might go with an open fryer; they produce a crispier product, increase throughput, and allow plenty of freedom for customization.

Whether your goal is saving money on oil, maintaining consistent food quality, increasing capacity, or simply introducing an all-purpose ‘workhorse’ to your kitchen, we’ve got you covered.


Built to make your life easier.

For more than 60 years, Henny Penny has been leading the way in fryer innovation. Take, for instance, our built-in oil filtration systems that come standard on every open fryer. This automatic system helps extend oil life and reduces the manual effort required to keep your fryers functioning.

Quality you can trust.

Faster temperature recovery is also a hallmark of Henny Penny open fryers, with third-party testing confirming our designs help save energy and keep things running efficiently.
