Why You’ll Love This Recipe
This onion soup is not just any soup; it’s a comforting embrace on a chilly day. The combination of caramelized onions, hearty broth, and a crispy slice of buttered toast topped with melty cheese is irresistible. It’s incredibly easy to prepare, using ingredients you likely have on hand. And, the depth of flavor achieved in such a short cooking time will easily make this a staple in your meal rotation.
Ingredients Notes
For the best results, choose sweet onions for their caramelizing qualities. You’ll also need a good beef broth; homemade or store-bought, ensure it’s low-sodium to control the salt levels. A crusty baguette and Gruyère cheese create the perfect topping, but feel free to experiment with different bread and cheese combinations.
Recipe Steps
Step 1
Begin by slicing six large onions thinly. In a large pot over medium heat, melt two tablespoons of butter, then add the onions. Cook, stirring occasionally, until they turn a deep golden brown, about 45 minutes.
Step 2
Sprinkle one tablespoon of flour over the onions, stirring to coat. This ensures the soup will have a slightly thickened texture.
Step 3
Gradually add eight cups of beef broth to the pot, stirring constantly. Bring to a boil, then reduce the heat and let the soup simmer for another 30 minutes to meld flavors.
Step 4
Preheat your oven’s broiler. Ladle soup into oven-safe bowls, placing a slice of baguette on top of each. Generously sprinkle Gruyère cheese over the bread.

Storage Options
Leftover onion soup can be stored in an airtight container in the refrigerator for up to four days. For freezing, let the soup cool completely before transferring to a freezer-safe container, leaving some room for expansion. Reheat gently on the stove over low heat. Do keep in mind that the bread and cheese topping should be added fresh upon reheating, for best results.
Variations & Substitutions
If you’re looking to cater to dietary needs, consider using vegetable broth to make this a vegetarian dish. For a different take, swap out the Gruyère for Swiss or Parmesan cheese. Add sliced mushrooms or a hint of garlic for an extra flavor dimension.
Serving Suggestions
This soup makes a perfect centerpiece for a light lunch or part of a larger dinner. Pair it with a fresh green salad and a glass of crisp white wine for a balanced meal. It’s also a fantastic starter for your next dinner party!
Frequently Asked Questions
Can I make this soup ahead of time? Yes, you can prepare the soup base a day ahead, storing it in the refrigerator. Simply reheat it on the stovetop, and complete the bread and cheese topping just before serving.
What can I use instead of Gruyère cheese? While Gruyère is traditional for its great melting qualities, you can substitute it with Swiss cheese, sharp cheddar, or even a mixture of Parmesan and mozzarella for a different flavor profile.
Is there a way to make this soup gluten-free? Absolutely! Use a gluten-free bread option for the topping and make sure the broth is certified gluten-free. You can also omit the flour used for thickening without much impact on the overall texture.
