Frying tofu in a toaster is not recommended and can be dangerous. Toaster ovens are not designed for deep frying or cooking with large amounts of oil, and attempting to fry tofu in a toaster could lead to fire hazards, damage to the toaster, and personal injury.
Toasters and toaster ovens are typically meant for toasting, baking, and light cooking tasks, such as reheating or cooking small items like bread, pastries, and pizza slices. They are not designed to handle the high temperatures and large quantities of oil required for deep frying.
If you want to fry tofu or any other food that requires deep frying, it's best to use a dedicated deep fryer or a heavy-bottomed pot with enough oil to fully submerge the tofu pieces. Always follow the safety guidelines and instructions for the specific equipment you are using.
If you prefer a healthier cooking method for tofu, consider baking it in the toaster oven or using the toaster oven for other creative tofu recipes. However, keep in mind that toaster ovens have their limitations, and for more extensive cooking tasks, a regular oven or stovetop may be more suitable.
