Ingredients You’ll Need
The magic of this Easy French Onion Soup Recipe lies in its simple yet essential ingredients. Each one plays a key role, from the sweetness of caramelized onions to the savory richness of beef broth and the creamy melt of Gruyère cheese. Here are the essentials you’ll gather before you start:
- 4 large onions, thinly sliced: They are the star of the show, slowly caramelizing to bring natural sweetness and deep flavor.
- 2 tablespoons butter: Adds richness and helps the onions soften gently without burning.
- 4 cups beef broth: Builds the hearty base of the soup, giving it that classic savory backbone.
- 1 teaspoon thyme: Fresh or dried thyme gives a subtle herbal brightness that lifts the soup.
- 1 tablespoon flour: Acts as a light thickener, giving a slight velvety texture to the broth.
- 4 slices baguette: Toasted to crispy perfection, they provide a wonderful textural contrast.
- 1 cup Gruyère cheese, shredded: Melts beautifully over the bread for that iconic bubbly, golden topping.
- Salt and pepper to taste: Essential finishing touches to balance and enhance all the flavors.
How to Make Easy French Onion Soup Recipe
Step 1: Caramelize the onions
Start by melting the butter in a large pot over medium heat. Add the thinly sliced onions and cook them slowly, stirring occasionally. This low and slow approach allows the onions to transform into a luscious golden-brown caramelized state, releasing their natural sugars and building a rich foundation for your soup. This process takes about 25 minutes, so be patient—it’s worth every minute!
Step 2: Create the roux
Sprinkle the tablespoon of flour evenly over the caramelized onions and stir well to combine. Cooking the flour with the onions for about 2 minutes helps to cook out any raw taste and forms a light roux that will gently thicken your soup without overpowering the flavor.
Step 3: Add broth and thyme
Pour in the beef broth and add the thyme. Bring everything to a boil, then reduce the heat and let the soup simmer gently for 15 minutes. This simmering step lets the flavors marry and intensify, making every spoonful a cozy, savory experience.
Step 4: Season perfectly
Before you move on to the final touches, season the soup with salt and black pepper according to your taste. Because of the slow caramelization and the rich broth, the flavors will be deeply developed, so go easy and adjust gradually.
Step 5: Prepare the topping
While the soup simmers, set your oven to toast the baguette slices until they are golden and crisp. Once toasted, pile the shredded Gruyère generously over each slice. This step is crucial because as the soup is served, these cheese-topped croutons will melt gloriously on top, creating that trademark bubbly crown.
Step 6: Serve and enjoy
Ladle the hot soup into bowls and gently float a cheesy baguette slice on top of each. The contrast of textures—from the smooth, savory broth to the crisp bread and stretchy melted cheese—will make you want to dive right in.
How to Serve Easy French Onion Soup Recipe
Garnishes
For an extra touch of flair, sprinkle a little fresh chopped parsley or thyme leaves on top. It adds a pop of color and a subtle freshness that brightens the deep flavors beautifully. A light drizzle of olive oil can also complement the soup’s rich profile.
Side Dishes
This soup pairs wonderfully with a simple green salad dressed lightly with vinaigrette or even a crisp glass of white wine. If you want a heartier meal, roasted vegetables or a charcuterie board can accompany the soup perfectly without overshadowing it.
Creative Ways to Present
Serve your Easy French Onion Soup Recipe in mini cast iron pots or individual oven-safe crocks for a charming artisanal touch. You can broil the cheese-topped bread directly on the soup in these containers for an extra bubbly finish. It’s a delightful way to impress guests and elevate a humble dish.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, store the soup (without the cheese toasts) in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen overnight, so leftovers can taste even better.
Freezing
Freezing leftover soup is totally doable. Just pour the cooled soup into freezer-safe containers, leaving some space for expansion. It will keep well for up to 2 months. When ready to eat, thaw overnight in the fridge before reheating.
Reheating
Reheat the soup gently on the stove over medium heat, stirring occasionally until warmed through. Add fresh cheese-topped baguette slices just before serving to maintain that satisfying crunch and gooey topping.
FAQs
Can I use chicken broth instead of beef broth?
Yes, you can substitute chicken broth for beef broth if you prefer a lighter soup. Keep in mind the flavor will be milder, but still delicious and comforting.
What type of onions work best for this soup?
Yellow onions are best for their balance of sweetness and pungency. They caramelize nicely and develop rich flavor over time, which is essential for this recipe.
Is Gruyère cheese necessary, or can I use another cheese?
Gruyère is traditional and prized for its creamy melt and nutty flavor. However, Swiss or even mozzarella can work in a pinch, though the taste and texture might differ slightly.
How do I prevent the onions from burning while caramelizing?
Take your time and cook the onions on medium to medium-low heat. Stir frequently and if they start to stick, add a splash of water to loosen them and prevent burning.
Can this soup be made vegetarian?
Absolutely! Replace beef broth with a rich vegetable broth and skip the cheese or use a plant-based alternative for a vegetarian version full of flavor.

- 1 tablespoon flour
- Salt and pepper to taste
Toppings
- 4 slices baguette
- 1 cup Gruyère cheese, shredded
Instructions

- Add Flour: Sprinkle the flour over the caramelized onions and stir well to combine. Cook for an additional 2 minutes to form a slight roux, which helps thicken the soup.

- Season: Taste the soup and season with salt and pepper according to your preference.
- Prepare Toppings: While the soup simmers, toast the baguette slices in the oven until golden and crispy. Once toasted, top each slice evenly with shredded Gruyère cheese.

Notes
- For a vegetarian variation, use vegetable broth instead of beef broth and omit the cheese or substitute with a vegetarian cheese alternative.
- Caramelizing onions slowly is key to developing rich flavor; avoid rushing this step.
- You can broil the cheese topped baguette slices briefly instead of toasting separately to melt the cheese perfectly.
- Gruyère cheese adds authenticity, but Swiss or Emmental are good alternatives if unavailable.
- Adjust thyme quantity according to taste preference or substitute with fresh thyme for more aroma.
