Essential Ingredients
Here’s what you’ll need to make this delicious dish:
Onions: Use yellow onions for their sweetness, ideally about four medium-sized ones for depth of flavor.
Butter: A generous amount helps caramelize the onions perfectly, giving them that rich golden color.
Beef Broth: Opt for low-sodium broth to control saltiness while enhancing the savory flavor profile.
Cognac or Sherry: A splash adds sophistication and depth; don’t skip this step if you can help it!
Baguette: Slices should be sturdy enough to hold up under the gooey cheese without disintegrating.
Gruyère Cheese: The meltability factor is key here—grate it fresh for maximum flavor and texture.

Let’s Make it Together
Slice those Onions!: Start by slicing your onions thinly; aim for even cuts to ensure they cook uniformly. A sharp knife works wonders here!
Caramelize Away!: In a large pot over medium heat, melt butter until foamy. Add your sliced onions and cook until they turn golden brown—about 30 minutes—stirring occasionally to avoid burning.
Add in Some Flavor!: Pour in cognac or sherry to deglaze the pot, scraping up all those flavorful brown bits stuck at the bottom. Let it simmer for about five minutes until slightly reduced.
Pour in that Broth!: Add beef broth into the pot along with some salt and pepper. Bring everything to a gentle boil before reducing heat and letting it simmer for another 20 minutes. Your kitchen will smell divine!
Bake Those Bread Slices!: While your soup simmers away, toast baguette slices until golden brown either in an oven or toaster; this gives them that satisfying crunch against the creamy soup.
Top It Off!: Ladle hot soup into oven-safe bowls and place toasted baguette slices on top, covering them generously with grated Gruyère cheese. Pop these under a broiler until bubbly—just 3-5 minutes will do!
This easy French onion soup is more than just a meal; it’s an experience filled with warmth and laughter. Enjoy every bite!
