Ingredients
Instructions
- Simmer thinly sliced onions in water until tender.
- Dissolve chicken bouillon in the water.
- Add the dissolved bouillon to the onions and simmer a few minutes.
- Place a few croutons and a slice of French bread or toast in each bowl.
- Add a slice of Swiss or Mozzarella cheese on top of the bread.
- Pour the hot soup over the cheese and bread in each bowl.
- Sprinkle with Parmesan cheese and let stand for a minute or two to melt the cheese.
Tips & Substitutions
For added flavor, try sautéing the onions in a bit of butter before simmering them in water. If you prefer a vegetarian version, substitute the chicken bouillon with vegetable bouillon. You can also use Gruyère cheese instead of Swiss or Mozzarella for a more traditional taste. This soup pairs beautifully with Noodle Soup for a comforting meal.
Serving Suggestions
Serve the soup hot, garnished with additional Parmesan cheese and fresh herbs like thyme or parsley for a pop of color. It pairs wonderfully with a simple green salad or a side of crusty baguette. For a heartier meal, consider serving it alongside Chicken In Tomato And Onion Sauce.
Storage & Reheating
Store leftover soup in an airtight container in the refrigerator for up to 3 days. To reheat, warm the soup gently on the stove or in the microwave until hot, ensuring not to boil it to preserve the texture of the cheese. You can also freeze the soup, but it's best to add the cheese when serving.

Frequently Asked Questions
Can I use different types of cheese?
Yes, you can absolutely experiment with different cheeses. Gruyère is a classic choice for French onion soup, but you can also use a sharp cheddar or a creamy fontina for a unique twist. Just remember that the cheese should melt well to achieve that perfect gooey topping.
How can I make this soup thicker?
If you prefer a richer flavor, adding a splash of dry white wine during the onion cooking process can enhance the depth of the soup. Just ensure to let the alcohol cook off before adding the broth.
Can I make this soup ahead of time?
Absolutely! French onion soup can be made a day in advance. Simply prepare the soup and store it in the refrigerator. When ready to serve, reheat the soup on the stove, then assemble with bread and cheese just before serving for that freshly melted topping.
