Ingredient Notes & Substitutions

Equipment Needed
To make French Onion Soup, you’ll need a few pieces of basic kitchen equipment, including a large pan, a bowl, a cheese grater, and an oven. You’ll also need some broiler-safe bowls to assemble and serve the soup.
Some other equipment you may find useful includes:
- A mandoline or sharp knife to slice the onions thinly and evenly
- A wooden spoon or silicone spatula to stir and scrape the bottom of the pan
- A cheese cloth or fine-mesh strainer to strain the soup and remove any solids
Step-by-Step Instructions

- Add beef broth to the pan and bring to a boil, then reduce heat and let simmer for 10 minutes.
- Butter slices of bread and toast until golden brown.
- Assemble the soup by placing toasted bread slices in the bottom of a bowl, ladling the onion soup over the bread, and topping with grated cheese.

Visual Guide & Tips
As you cook, keep an eye on the color and texture of the onions, as they should be dark golden brown and caramelized. The beef broth should be rich and flavorful, with a deep, savory color. And, when assembling the soup, make sure to toast the bread until it’s golden brown and crispy.
Some other tips to keep in mind:
- Use a medium-low heat to caramelize the onions, as high heat can burn them
- Stir occasionally to prevent the onions from burning or sticking to the pan
- Don’t overfill the bowls, as the soup will bubble up and overflow during baking
Pro Tips & Tricks
Achieving perfect caramelization is key to making a great French Onion Soup. To do this, cook the onions over medium-low heat, stirring occasionally, until they are dark golden brown and fragrant. You can also add a touch of sugar to help bring out the natural sweetness of the onions. The caramelization process involves complex chemical reactions like the Maillard reaction that create the rich flavors and colors.
Using high-quality Gruyère cheese is also crucial, as it adds a rich, creamy element to the dish. Look for a cheese with a nutty, slightly sweet flavor, and grate it freshly over the soup for the best results.
Some other tips to keep in mind:
- Use a mixture of sweet and savory ingredients to balance out the flavor of the soup
- Add a touch of acidity, such as a splash of white wine or a squeeze of fresh lemon juice, to brighten the flavor
- Experiment with different types of cheese, such as Comté or Beaufort, to find the one you like best
