French onion soup has been one of the most adored soups from the time I first tried it in middle school French class. Many restaurants have perfected French onion soup, and now you can too!
French onion soup is not something I make often, because it is slightly time consuming, but I’m always happy when I do make it. It is especially comforting in the depths of winter. Preparation time for this soup takes about an hour and forty-five minutes, and you can’t walk away for too long during the caramelizing of the onions. It’s a good feeling once you see those golden, perfectly caramelized onions. Depth and richness is added to this soup with a generous splash of pinot noir and hearty beef stock. We use Homemade Croutons to soak up this delicious broth.
The secret to the best French onion soup is the caramelized onions. It is important to cook them low and slow, stirring occasionally but not constantly. When all the water is absorbed out of the onion, they begin to brown and develop a natural sweetness. This is why using yellow onions is better than other onion varieties, as yellow onions are naturally sweet. The texture of caramelized onions is almost melt in your mouth soft. It always seems like overkill to start with a pot full of sliced onions, but over time, they will reduce to about a cup of caramelized onions.

Important note about Broiling
An important note is to use good quality oven safe baking bowls or French onion soup crocks. This will ensure that they do not break in the oven while broiling the cheese.
Can this soup be refrigerated?
Yes! French onion soup can be refrigerated without the croutons and cheese. To prepare it after refrigeration, microwave the soup in the baking bowl or crock for 3 minutes. Add the croutons to the bowl, cover with the cheeses, and broil for 4-5 minutes. This soup can also be frozen, again, without the croutons and cheese. Thaw frozen soup in the refrigerator and reheat the same way as if it were refrigerated.
