Essential Ingredients
Here’s what you’ll need to make this delicious dish:
Sweet Onions: Use Vidalia or Walla Walla onions for optimal sweetness; they caramelize beautifully.
Butter: A good quality unsalted butter enhances the richness of the broth.
Beef Broth: Opt for low-sodium beef broth to control salt levels while still capturing deep flavors.
Dry White Wine: A splash adds acidity and depth; choose a wine you’d enjoy drinking.
Baguette: A crusty baguette is perfect for soaking up the broth and supporting that melty cheese layer.
Gruyère Cheese: This cheese melts beautifully and adds a nutty flavor; feel free to mix with Parmesan for extra richness.

How to Make French Onion Soup
Caramelize the Onions: Start by melting butter in a large pot over medium heat. Add thinly sliced sweet onions and sauté until they turn translucent and golden brown – about 30 minutes. Stir occasionally to prevent burning.
Add Flavorful Elements: Once onions are caramelized, sprinkle them with salt and sugar to enhance sweetness further. Pour in dry white wine and scrape any bits stuck on the bottom – those add extra flavor!
Pour in Beef Broth: Gradually pour in low-sodium beef broth while stirring gently. Bring the mixture to a simmer; let it bubble away for about 20 minutes to meld those flavors together.
Prepare Your Baguette Topping: While your soup simmers, slice your baguette into thick pieces and toast them lightly until golden brown – this ensures they hold up against all that delicious broth.
Melt Cheese on Top: Ladle hot soup into oven-safe bowls, place toasted baguette slices on top, then generously sprinkle Gruyère cheese over everything. Place bowls under broiler until cheese is bubbly and golden brown.
Enjoy this delightful French onion soup with family or friends; it’s sure to be a hit at any gathering!
