This high heat allows the bread to quickly take on color and become crispy while warming fillings in just seconds.

Need for Speed: How Does Subway Achieve Lightning-Fast Toasting?

Subway uses high-speed impingement ovens that rapidly toast sandwiches using jets of hot air.

The combination of powerful fans and heating elements allows the oven to very quickly surround food with hot air, toasting subs in just seconds.

This allows Subway to toast sandwiches faster than a regular pop-up toaster or convection oven.

Time is of the Essence: How Long Does Subway Toast Their Subs?

The total toasting time for a Subway sandwich is around 3-5 seconds. The speed of the impingement oven allows subs to receive optimum toasting in just a few seconds.

Employees are trained on how long to toast particular subs to achieve the perfect level of crispness without burning.
