I have often thought about what to serve with French Onion Soup. You need a side dish that is just as amazing as the caramelized onion soup!
French onion soup is incredibly rich and delicious. It has lots of herbs like sage and thyme. The caramelized onions are also very powerful and sweet.
You also can’t forget about the melted gruyere cheese that tops the French onion soup.
You need to keep all of these strong flavors in mind when choosing a side dish recipe for French onion soup.
We considered all of the flavors in French onion soup when making this list of the best French onion soup side dishes. We had to do a lot of taste testing too!
It is also important to think about the seasonality of French onion soup. It is definitely a cold-weather dish. You want to choose a side dish that has wintery, warm flavors.
This is a lot to think about when planning a meal! Don’t worry because we did all the hard work for you.
