French Onion Soup

Yayy! Its thanksgiving time! Time for some exciting desserts and other recipes too! To start with, the first on the list is soup. Winters always makes us lazy and crave for something warm and comfortable, especially food.  So, who is ready for a cozy bowl of French onion soup?

Perfectly caramelized onions flavored with broth (traditionally beef) and a hint of wine and mild spices is the best crowd pleaser for this thanksgiving! The best part of the soup is yet to come. Those toasted baguette slices or croutons with melting gruyere or even mozzarella cheese is the most amazing part of the soup.

The name –French onion soup can be intimidating for many. Fear not, because this soup is extremely simple and includes only a few and basic ingredients. To start off with, onions are an important part of this soup recipe.

So, which onions to choose from – yellow, white or red! To be speaking in fairness, I have used only red onions because of the unavailability of white or yellow onions here in my place. But, the original recipe calls for yellow onions. But, you can replace it with any type available- red or white!

White onions tend to be sweet whereas the red onions have a very sharp taste. Yellow onions are perfect for any type of cooking especially ones that involve caramelizing. Now, to make this French onion soup, the main step is to caramelize onions slowly in butter. This step brings out most of the flavors in the soup!

So, how to caramelize onions? This requires plots of patience because you have to take it low and slow. This is the most crucial part. It is very important to cook the onions in a low heat because you do not want the onions to get burnt. Also, taking it slow means that the sugar in the onions tend to melt and gives it the natural and beautiful golden color. That’s the whole point right?!

Browning the onions is different from caramelizing it. So, if you rush the process then the real flavors will not be brought out. Also, another thing is to stir it to again make sure that it does not burn. Do not neglect them and walk away from the stove while doing this. Oh, come-on! A French onion soup without perfect caramelized onions is nothing, right?!

Back to the ingredients, one other important ingredient which cannot be substituted is butter. For that perfect flavor, butter is very important. At the end, flavor is all that matters right?! So, do not skip it or replace it!

Next, to deglaze, we use wine and broth / stock. You can use any type of wine – white or even red. You can use cognac or sherry too! Anyways, using wine is optional. Beef broth is traditionally used to deglaze. But again, I have used chicken broth here. If you like beef broth, you are more than welcome to try it traditionally and let me know too!

Use baguette slices or croutons to top the soup with. Again, any melting cheese can be used – gruyere, or even mozzarella. I had a combination of mozzarella and cheddar which I have used. You can toast the bread slices in the oven or even on a tawa and then top it off with cheese and melt it in the stovetop itself. If you happen to have a Dutch oven, then you can serve the soup in microwave soup bowls and place the bread slices topped with cheese on the soup and broil it until melted and golden brown.  

This French onion soup is a meal in itself. It can be paired with some salads on the side. It can also be had as a starter for a very elaborate meat dinner. This is a classic soup recipe to be had the way you like it. Enjoy having this French onion soup with your loved ones on a very cold day! And a very Happy Thanksgiving too! Stay safe; stay healthy! Happy cooking and eating!

  • Yellow onions are best for the recipe. But you can substitute with white or even red onions if yellow ones are not available.
  • Do not saute the onions on high heat. This will only burn the onions and not caramelize them.
  • Stir in between to make sure the onion does not burn.
  • Butter gives the original French taste. Do not replace it.
  • You can use white wine / red wine / sherry or even cognac. Or substitute with a bit of white wine vinegar too, to make it alcohol-free.
  • To toast the baguette slices, you can toast them in a pre-heated oven until golden or even on a tawa.
  • If using oven, then ladle the soup into microwave safe soup bowls, place a toasted baguette slice and top with grated cheese and broil until cheese is melted and golden spots appear.
