There’s no comforting soup like a hearty bowl of French onion soup, and this recipe will show you how to make it at home with no mistakes. This famous soup involves caramelizing onions to bring out their natural sweetness and then slow cooking them in a broth. The result is a rich and flavorful soup perfect for chilly winter nights.

The Finest Types Of Onions To Use

For this soup, you’ll need to use yellow onions. They have the perfect balance of sweetness and sharpness essential for this dish. You could also use white onions, but they aren’t quite as sweet, so you may need to add more sugar to the recipe.

The Impact Of Wine

While the soup is cooking, the wine will evaporate and leave behind its flavor. This is why it’s essential to use a good quality wine that you enjoy drinking. If you don’t like the taste of wine, you can omit it from the recipe altogether.

Substitutes and Alterations You Can Make

  • If you’re not a fan of onions, you can try substituting shallots or leeks. These vegetables have a similar taste and will work well in this soup.
  • If you want to make a vegetarian version of French onion soup, you can use vegetable broth instead of beef broth.
  • If you prefer not to include alcohol in your soup, you can leave out the wine and use additional broth.

How To Slice Your Onions

One of the most critical steps in making this soup is slicing your onions properly. You’ll want to slice them very thinly so that they caramelize evenly. The best way to do this is to use a mandoline slicer, but you can also use a sharp knife if you’re careful.

Topping Variations

Traditionally, you can top the french onion soup with a piece of toasted bread and some Gruyere cheese. However, there are many other variations that you can try. Some people like to top their soup with croutons, while others prefer to use Parmesan cheese. The best types of cheese to top the soup include:

  • Mozarella
  • Gouda
  • Parmesan
  • Gruyere
  • Provolone
  • Cheddar

Tips For Perfection

  • When cooking the onions, be sure to stir them frequently not to burn.
  • If your soup is too thick, you can thin it out with additional broth.
  • If your soup is too thin, you can thicken it by cooking it for an additional hour or adding some flour to the mixture.
  • Taste the soup before adding any salt, as the broth may already be salty enough.
