They are the same concept but don't taste the exact same. Shallots have a flavor that is a mix of a mild onion with a bit of garlic. They're delicious but the flavor isn't as strong as fried onions. In U.S.-based grocery stores, you can purchase cans of fried onions. Almost all of those brands are breaded fried onions. If you're gluten-free, these shallots will accommodate your dietary needs.
