Ingredients for French Onion Soup Classic
To create this delightful french onion soup classic, you’ll need a handful of simple yet essential ingredients. Each one plays a vital role in crafting that rich, comforting flavor we all love. Here’s what you’ll need:
- 4 large onions, thinly sliced: Choose sweet varieties like Vidalia or Walla Walla for a naturally sweeter flavor. The key is to slice them evenly so they cook at the same rate.
- 2 tablespoons unsalted butter: This adds richness and depth to the soup. Feel free to let it melt gently in your Dutch oven before adding the onions.
- 1 tablespoon olive oil: This helps prevent the butter from burning and adds a lovely flavor. A good quality extra virgin oil works wonders!
- 8 cups beef broth: Homemade is best, but store-bought works just fine! Look for low-sodium options to control the saltiness. The broth is the heart of your soup, so choose one with robust flavor.
- 1 cup dry white wine (optional): This adds a touch of acidity and enhances the overall flavor. If you’re not using wine, you can substitute with an extra cup of broth.
- For the Topping:
- 4 slices French bread: You’ll want this toasted to a golden crisp. It will soak up the broth while still holding its shape when topped with cheese.
- 1 cup gruyere cheese, shredded: This cheese melts beautifully and adds a nutty flavor. If you can’t find gruyere, look for a nice Swiss cheese as a substitute.
With these ingredients at hand, you’re well on your way to creating a soul-soothing bowl of classic French onion soup. Trust me, the magic of caramelized onions and melted cheese will have you dreaming of this dish long after it’s gone!
How to Prepare French Onion Soup Classic
Making a classic French onion soup is truly an art, and the process is just as delightful as the final product! Let’s dive into the steps that will lead you to a bowl of cozy goodness.
Step 1: Caramelizing the Onions
The magic begins with the onions. In your Dutch oven, melt the unsalted butter and olive oil over medium heat. Once the butter is bubbling, it’s time to add your thinly sliced onions. Now, here’s where patience comes in! You’ll want to cook those onions for about 30 minutes, stirring occasionally. The goal is to achieve that beautiful golden-brown color. You’ll know they’re done when they are soft and fragrant, and you can see that rich caramel color developing. Trust me, the aroma alone will have everyone peeking into the kitchen!
Step 2: Adding the Broth
Once your onions are perfectly caramelized, it’s time to elevate their flavor with beef broth. Pour in the 8 cups of beef broth and the dry white wine (if you’re using it). Give it a good stir to mix everything together. Increase the heat and bring the mixture to a boil, then reduce the heat to low and let it simmer for about 15 minutes. This simmering time is crucial as it allows all those flavors to meld together beautifully. You can take a moment to taste the broth during this step; feel free to adjust the seasoning if needed!
Step 3: Preparing for Broiling
Now, let’s get ready for the grand finale! Preheat your broiler to high while you prepare your serving bowls. Ladle the hot soup into oven-safe bowls, filling them generously. Top each bowl with a slice of toasted French bread, ensuring it sits right on the surface of the soup. Then, sprinkle a generous amount of shredded gruyere cheese over each slice. You’ll want enough cheese to create that glorious, gooey topping that we all crave!
Step 4: Broiling the Soup
It’s time to transform your soup into something spectacular! Place the bowls under the broiler for about 2-3 minutes. Keep a close eye on them because we want that cheese to melt and bubble, turning a lovely golden color. You’ll know it’s ready when it looks irresistibly gooey and slightly browned. Carefully remove the bowls from the oven (they’ll be HOT!), and let them cool for a minute before serving. Now, take a moment to admire your work—this is a labor of love that’s sure to impress!

FAQ About French Onion Soup Classic
Q1: What’s the best type of onions to use for French onion soup?
For the best flavor, I recommend using sweet onions like Vidalia or Walla Walla. They caramelize beautifully and bring a natural sweetness to your french onion soup classic. Yellow onions can also work in a pinch, but sweet onions really shine in this recipe!
Q2: Can I make this soup ahead of time?
Absolutely! This classic French onion soup is perfect for making ahead. Just prepare the soup, let it cool, and store it in the refrigerator. When you’re ready to serve, reheat it on the stove and follow the broiling steps to finish. It actually tastes even better the next day as the flavors meld!
Q3: Can I use a different cheese instead of gruyere?
While gruyere is the traditional choice for its melting qualities and flavor, you can substitute it with Swiss cheese or even mozzarella if needed. Just keep in mind that the flavor profile will change slightly, but it’ll still be delicious!
Q4: How can I make this soup vegetarian?
To make a vegetarian version of this french onion soup classic, simply swap out the beef broth for a rich vegetable broth. You can also enhance the flavor by adding a splash of soy sauce or miso paste for depth. The caramelized onions will still shine through!
Q5: What should I serve with French onion soup?

- Wine is Optional but Recommended: Adding dry white wine enhances the flavors beautifully. If you’re not a fan of wine, you can use additional broth or even a splash of apple cider vinegar for some acidity.
- Experiment with Cheese: While gruyere is traditional, don’t hesitate to mix it up! Combine it with a bit of aged cheddar or fontina for a unique twist. Just keep in mind that the melting quality will vary.
- Make it Ahead: Remember, this soup tastes even better the next day! If you’re prepping in advance, store the soup and toppings separately until you’re ready to broil. This keeps the bread from getting soggy.
- Add Fresh Herbs: A sprinkle of fresh thyme or parsley right before serving can elevate your soup with a pop of freshness. It’s a simple touch that makes a big impact!
- Mind the Broiling: Keep a close watch when broiling! Ovens can vary, and you don’t want your cheese to burn. You’re aiming for bubbly and golden, not charred!

Storage & Reheating Instructions
When it comes to leftovers, you’ll want to ensure your classic French onion soup stays as delicious as the day you made it! Here’s how to properly store and reheat it:
Storing Leftovers: Allow the soup to cool to room temperature before transferring it to an airtight container. It’s best to store the soup without the toppings to maintain the bread’s crispness and the cheese’s texture. If you have any leftover toasted bread, store it separately to keep it crunchy. The soup can be kept in the refrigerator for up to 3-4 days.
Freezing for Later: If you’d like to enjoy your french onion soup classic later on, you can freeze it! Just make sure to cool it completely, then portion it into freezer-safe containers or resealable bags. It should keep well for about 2-3 months. Remember to label the containers with the date for easy reference.
Reheating Instructions: When you’re ready to enjoy your soup again, simply thaw it overnight in the refrigerator if frozen. To reheat, pour the soup into a pot and warm it over medium heat, stirring occasionally, until heated through. If the soup thickens up a bit, feel free to add a splash of broth or water to reach your desired consistency.
Once hot, follow the broiling steps as outlined earlier to top it with fresh bread and cheese for that cozy, golden finish. Enjoy every comforting spoonful just like it was freshly made!
