A toaster oven uses about half the energy of a conventional oven to cook the same meal. And with a convection toaster oven, the savings increase.
Of course, whether you're using a full-sized oven or a toaster oven, it's important to cook efficiently:
Only preheat when necessary (usually only baking requires it),
Don't open the door to peek – it can lower the temperature by as much as 25 degrees.
Turn off the oven several minutes before the recipe indicates. The residual heat will keep the food warm enough to finish cooking.
Use glass or ceramic cookware. Glass and ceramics conduct and retain heat better than metal. If you switch to glass or ceramic, you can lower the oven temperature by 25 degrees.
