Why Youโll Love This Recipe
What makes this French onion soup unique? Itโs faster and lighter than traditional recipes, but just as rich and satisfying. Instead of hours of simmering, Iโve streamlined the process without sacrificing any of that deep, savory flavor. Plus, I use a hint of balsamic vinegar to add depth, which gives it a slightly sweet tang that complements the caramelized onions beautifully.
If youโve ever been overwhelmed by recipes that call for fancy cookware or complicated techniques, youโre in the right place. This soup is simple, delicious, and guaranteed to impress anyone at your table.
Tips for the Perfect French Onion Soup
- Take Your Time with the Onions: The key to great French onion soup is deeply caramelized onions. Donโt rush this stepโitโs worth every minute. Cook them low and slow until they turn a rich, golden brown.
- Donโt Skip the Balsamic Vinegar: This is my little twist! A splash of balsamic at the end of caramelizing the onions adds a unique depth of flavor.
- Use Good Cheese: Gruyรจre is the classic choice, but donโt let that stop you from experimenting. Swiss, provolone, or even a sharp cheddar work beautifully.
- Homemade Broth, If You Can: While store-bought broth is perfectly fine, a homemade beef or vegetable stock will elevate this soup to a whole new level.

Easy French Onion Soup Recipe
Serves: 4
Prep Time: 10 minutes
Cook Time: 50 minutes
Ingredients
- 3 large yellow onions, thinly sliced
- 3 tbsp unsalted butter
- 1 tbsp olive oil
- 1 tbsp sugar
- 1 tbsp balsamic vinegar
- 4 cups beef or vegetable broth
- 1 cup water
- 1/2 cup dry white wine (optional)
- 1 tsp fresh thyme leaves (or 1/2 tsp dried thyme)
- Salt and pepper, to taste
- 4 slices of baguette or crusty bread, toasted
- 1 1/2 cups shredded Gruyรจre cheese
Instructions
- Caramelize the Onions: In a large pot, melt butter with olive oil over medium heat. Add the onions and sugar, stirring to coat. Cook, stirring occasionally, until the onions are golden brown, about 25โ30 minutes. Stir in the balsamic vinegar and cook for another 2 minutes.
- Simmer the Soup: Add the broth, water, wine (if using), and thyme. Bring to a boil, then reduce heat to low and let simmer for 15โ20 minutes. Season with salt and pepper to taste.
- Assemble and Broil: Preheat your ovenโs broiler. Ladle the soup into oven-safe bowls. Top each with a slice of bread and a generous handful of shredded cheese. Place the bowls under the broiler until the cheese is bubbly and golden.
- Serve Hot: Carefully remove the bowls (theyโll be hot!) and serve immediately. Enjoy the cheesy, oniony goodness!

Common Questions About French Onion Soup
1. Can I make this soup vegetarian?
Absolutely! Just use vegetable broth instead of beef broth. The balsamic vinegar adds enough depth that you wonโt miss the meat.
2. Can I use a different type of onion?
Yes! While yellow onions are traditional, sweet onions like Vidalia or red onions can be used for a different flavor profile.
3. What if I donโt have oven-safe bowls?
No problem! Toast the bread slices with cheese on a baking sheet under the broiler, then place them on top of the soup just before serving.
4. Can I make this soup ahead of time?
Definitely! The soup itself can be made a day or two in advance and reheated. Wait to add the bread and cheese until just before serving.
