French Onion Soup

About French Onion Soup:

Onion soups have been popular since the Roman times– often as an inexpensive way to make a meal as onions were easy to grow. The modern version of this soup originated in Paris.  It’s a beef broth soup with plenty of sauteed (or caramelized) onions, and it’s usually topped with a melted cheese slice of baguette.  Sherry or brandy are often added to the soup before serving. In the United States, French Onion Soup surged in popularity in the 60’s- when French cuisine was becoming popular.

French Onion Soup

Lately I’ve been craving soup on a weekly (sometimes daily) basis. It makes the perfect lunch. I can make a big pot of soup on Sunday and then portion it out to take to work with me over the next few days. Lunches made and ready to go for days? Yes, please!

Recently I made a big pot of this French Onion Soup, and it was delicious for Sunday dinner on a cold, rainy day. There’s something magical about toasted cheesy bread on top of a hot bowl of soup! When I make this soup, I like to make extra slices of cheesy bread for dipping. You can add them to the baking sheet when you put your soup bowls into the oven under the broiler.

French Bread in Easy French Onion Soup

Do you order French Onion Soup often when you eat out? I rarely do, but I really enjoyed this homemade version. As you expect from French Onion Soup, this soup is rich and comforting. Slowly caramelizing the onions on the stove brings out their sweetness and adds so much flavor to this soup. Really, you won’t believe how easy it is to make!

The leftovers of this soup make a delicious lunch that you will look forward to eating! If you do have leftover soup, don’t add the cheesy bread until right before serving. With my leftovers, I served bread on the side since I didn’t have time to worry about putting my soup under the broiler at lunchtime.

    Amazing soup! Been searching for a recipe that tastes like one from the French style chain (minus the beer) and FOUND it! Even without the cheese/ bread it tastes so good. Thank you for sharing.
