Essential Ingredients

Here’s what you’ll need to make this delicious dish:

Yellow Onions: Use about 4-5 medium onions for the best sweetness when caramelizing.
Beef Broth: Opt for low-sodium beef broth to control saltiness while enhancing flavor.
Dry White Wine: A splash adds depth; choose something you’d enjoy drinking!
Butter: Unsalted butter works best for cooking down those onions to golden perfection.
Baguette: Sliced into rounds, it’s essential for soaking up that delicious broth.
Gruyère Cheese: This melty cheese is a must-have; it brings creaminess and richness!
Fresh Thyme: A few sprigs will elevate the flavor with herby notes.
Salt and Pepper: Season well to enhance all those yummy flavors.

The full ingredients list, including measurements, is provided in the recipe card directly below.

Let’s Make it together

Caramelize Those Onions: Start by melting 4 tablespoons of butter in a large pot over medium heat. Add thinly sliced onions and stir occasionally until they turn golden brown—about 25-30 minutes. Be patient; they’ll reward you later!

Deglaze with Wine: Pour in half a cup of dry white wine after the onions become deeply caramelized. Scrape any tasty bits off the bottom of the pot—this step adds incredible flavor!

Add Broth and Seasonings: Once deglazed, add 6 cups of low-sodium beef broth along with fresh thyme sprigs. Bring everything to a gentle simmer for about 20 minutes so those flavors can mingle beautifully.

Prepare Your Baguette Topping: While your soup simmers away like magic, slice your baguette into thick rounds. Toast them lightly until golden brown—this ensures they won’t go soggy when added to the soup later.

Assemble and Broil : Ladle hot soup into oven-safe bowls and top each with toasted baguette slices and generous amounts of Gruyère cheese. Pop them under the broiler until bubbly and golden—around 3-5 minutes—but keep an eye on them!

Savor Every Bite!: Remove from oven (careful—these bowls are hot!). Allow them to cool slightly before serving—you don’t want anyone burning their tongue! Serve with a sprinkle of fresh thyme on top for that extra flair.

French onion soup is more than just a dish; it’s an experience filled with warmth and comfort. Enjoy every spoonful as you share laughter and stories around your dinner table!
