Preheating in a toaster oven is very different from a traditional wall oven. The space inside traditional ovens is huge and preheating can 10 to 20 minutes. Thatâs a lot of energy being used to heat all that air! The interior of toaster ovens, on the other hand, are very small. Even the largest models donât have all that much air to heat up.
1 Be sure you are waiting long enoughâit can take from 15 to 20 minutes to heat the oven to 350Â°F. 2  Keep the door closed during preheat to minimize the time required.  If your oven has a hidden heat element (where the heating element is hidden under the floor of the oven), it may take longer to preheat.
