  • 1 baguette, sliced into 1-inch thick rounds: For that perfect crusty topping. You can grab this during your normal shopping trip!

Here’s my classic French onion soup secret that takes it from good to incredible: Don’t skimp on the onions! Seriously, use those four large onions for the best depth of flavor.

For ingredient prep shortcuts on busy weeknights, you can slice the onions ahead of time and store them in the refrigerator. Just make sure they’re in an airtight container to prevent them from drying out.

I love adding extra garlic to my classic French onion soup for that extra kick, but that’s totally optional. Play around with the seasonings and make it your own!

Let’s Make Some!

This is my favorite part of making classic French onion soup – watch the magic happen! Follow these simple steps, and you’ll be enjoying a bowl of pure comfort in no time. For a more detailed guide, check out this French Onion Soup recipe.

  1. Heat the olive oil in a large pot or Dutch oven over medium heat. Add the sliced onions and cook, stirring occasionally, for 30-45 minutes, or until they are deeply caramelized and golden brown. This is where the magic starts happening!
  2. Add the minced garlic, dried thyme, and bay leaf to the pot. Cook for another minute, until fragrant. The aroma will start to fill your kitchen.
  3. Pour in the beef broth and red wine. Bring to a simmer, then reduce heat and cook for 20-30 minutes, allowing the flavors to meld together. In my kitchen, this classic French onion soup usually takes around 25 minutes to meld together perfectly!
  4. Stir in the balsamic vinegar and season with salt and pepper to taste. Don’t be afraid to season generously – it really brings out the flavors.
  5. Preheat your broiler. Ladle the soup into oven-safe bowls. Top each bowl with a few baguette slices, overlapping them slightly. While your classic French onion soup is doing its thing, get ready for some amazing aromas!
  6. Sprinkle the Gruyere and Parmesan cheese over the baguette slices. Place the bowls under the broiler and broil for 2-3 minutes, or until the cheese is melted and bubbly and the bread is golden brown. Your classic French onion soup should smell absolutely incredible right now!
  7. Carefully remove the bowls from the oven and let them cool slightly before serving. Don’t worry if your classic French onion soup looks a little messy – that’s part of its charm!

One of my personal cooking discoveries is that adding a splash of sherry vinegar at the end of cooking can really brighten up the flavors. It’s a happy accident turned flavor booster!

For busy weeknights, you can make the soup base ahead of time and store it in the refrigerator for up to 3 days. Just add the baguette and cheese before broiling.
