If it fits, then yes! (After it’s baked, of course.) However, standard pieces of naan are much larger than a regular slice of sandwich bread. So, unless you tear it up into smaller pieces, it likely won’t fit in your toaster. A toaster oven would work perfectly. If you do toast smaller pieces of bread, be sure to watch them closely. Naan is thinner than regular sandwich bread so it’s more likely to burn quickly.
