This simple onion soup recipe can be the foundation for a variety of tasty soups and stews. 6 basic ingredients make this one come together with minimal effort, and is a great way to take advantage of onions on sale at the local grocery store.
We use MSG in this recipe for a few different reasons: first, it’s easier and more space-effective to keep MSG on hand in your pantry. Second, it results in the soup having a clean onion flavor and keeps it vegetarian if you are into that. This recipe could even be vegan if you swap out the butter for olive oil.
If you hate the idea of using MSG, you can swap out that ingredient and the water for an equal amount of stock. But before you get your pitchfork out, read about why I love MSG.
