Homemade French Onion Soup

The very first thing I ate after arriving in Paris last Spring was French Onion Soup.  Of course in Paris it is not called French Onion Soup, it is called Soupe à l’oignon.  No need for the French part because you’re in France!
Whenever I go to a restaurant that has French Onion Soup on the menu I order it, even here in the United States.  I love it but I had never made it at home because I thought it was just too hard to make.  I am happy to report that I was wrong!!
Remember those Slow Cooker Caramelized Onions I shared a few weeks ago?  Well, they make a perfect onion soup and make it so easy.

French Onion Soup

What is French Onion Soup?

French Onion soup is made with a base of meat stock or broth and onions. It is served “gratineed” which means it is topped with a slice of bread covered in cheese.  Place it under the broiler to melt the cheese and you have Soupe à l’oignon.  Translation:  delicious!

How to Make French Onion Soup

  • Broth. I used half beef broth and half chicken broth. You can use broth from a can or you can make your own.
  • Caramelized onions. I used my slow cooker to make my caramelized onions but they can also be made on the stove top in a pan. Add in as much caramelized onions as you like but I use 1/4 cup of onions to 2 cups of broth.

  • Baguette. Use a crusty French baguette. Slice the baguette into about 3/4 inch thick slices. Brush the bread with a little olive oil and placed it under the broiler to toast.

The Best Cheese to Use For French Onion Soup

Traditionally it is made with Gruyere and Parmesan cheese but I have also made it with Swiss and Mozzarella.

  • Cheese. Place the toasted bread on top of the soup in a bowl. Cover the bread with a slice of Swiss or Gruyere cheese and then sprinkled with grated Parmesan or Mozzarella cheese. My favorite part of French onion soup is the cheesy part on top. Lots of ooey, gooey cheese!
  • Broil. Place the bowl onto a cookie sheet and place it under the broiler.  Watch it carefully and pull it out when the cheese has melted and gotten bubbly and golden brown on top.

Can I Freeze It?

This soup is best frozen without the bread and cheese on top. Store the soup in the refrigerator in an airtight container for 3-4 days or in the freezer for up to 3 months. Thaw soup and reheat before adding bread and cheese on top.

Then grab a spoon and dig it!!  Just close your eyes and imagine yourself sitting at a little sidewalk cafe in Paris!  Oh la la!!

From some other tastes from France try these:

  • French Cream Puffs and Eclairs
  • French Macarons
  • Crepe Bar

    This turned out great. I used Gruyere and Parmesan cheeses. I like that this recipe calls for balsamic vinegar rather than red wine, the vinegar gives it a little more brightness. I did add a dash of soy sauce too. And I love the slow cooker caramelized onions. So easy to add to the soup and I have plenty left over to freeze or just eat up!

    Yum! What kind of onions did you use? Yellow or white or sweet?

      You can use either yellow or white. Don’t really need sweet because the onions sweeten up as they cook for so long. I think I used yellow this time because that is what I had.
