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 your thinly sliced onions and cook them slowly, stirring every so often. This patience is key—about 25 minutes of gentle cooking transforms the onions into irresistibly sweet, golden brown ribbons that form the rich foundation of your soup.
Step 2: Create a Roux Base
Sprinkle the flour over the caramelized onions and stir well to combine. Cooking this mixture for about 2 minutes will help develop a slight roux, adding body and thickness to the soup without overwhelming its delicate flavors.
Step 3: Add Broth and Herbs
Pour in the beef broth and add the teaspoon of thyme. Bring everything up to a boil, then reduce the heat so the soup gently simmers for 15 minutes, allowing all the flavors to marry beautifully.
Step 4: Season to Perfection
Before moving on, taste your soup and season with salt and pepper. These simple seasonings make all the difference, ensuring each spoonful is perfectly balanced.
Step 5: Prepare the Topping
While the soup is simmering, get your baguette slices into the oven to toast until they’re golden and crispy. Once toasted, sprinkle the shredded Gruyère cheese generously on top. The combination of crunch and gooey melted cheese is a huge part of what makes this Easy French Onion Soup Recipe so special.
Step 6: Assemble and Serve
To serve, ladle the hot soup into bowls, then gently float a cheesy baguette slice on top of each. The warmth of the soup will perfectly melt the cheese further, creating a delightful contrast of textures and flavors in every bite.

Creative Ways to Present

FAQs
Can I use a different type of cheese?
While Gruyère gives that classic nutty, creamy flavor, you can experiment with Swiss or even mozzarella if you prefer a milder taste or are in a pinch. Just choose cheeses that melt well for best results.
Is beef broth necessary, or can I use vegetable broth?
Beef broth provides deep savory notes essential to the traditional flavor, but vegetable broth is a fine substitute if you want a lighter or vegetarian option. Just keep in mind it will slightly alter the taste.
How long should I caramelize the onions?
Patience is key here. It typically takes around 25 minutes on medium heat for the onions to reach that perfect golden brown and sweet caramelized stage that defines this soup.
Can I make this soup gluten-free?
Yes! Simply swap out the flour for a gluten-free alternative and choose gluten-free bread for the topping. This way, everyone can enjoy this hearty soup without worry.
What’s the best way to get that crispy cheese topping?
Toasting the baguette slices first, then generously adding shredded Gruyère before broiling or baking until bubbly golden, gives you that perfectly crispy, cheesy crust that’s signature to this Easy French Onion Soup Recipe.
