Recipe preparation

Essential Ingredients

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

  • Onions: Use yellow or sweet onions for the best flavor; they caramelize beautifully.
  • Butter: The richness of butter adds depth and creaminess to the broth.
  • Beef Broth: Opt for low-sodium beef broth for better control over flavor.
  • Baguette: A crusty baguette is perfect for soaking up the broth and holding onto melted cheese.
  • Gruyère Cheese: This nutty cheese melts wonderfully; feel free to mix in some mozzarella if you like extra stretch!
  • Tarragon (optional): A sprinkle adds an aromatic twist without overpowering the dish.

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

Let’s Make it Together

Caramelize Those Onions: Start by slicing your onions thinly. In a large pot over medium heat, melt butter until bubbly. Add onions and stir frequently until they turn golden brown and fragrant—about 20-30 minutes should do the trick!

Add Some Flavor: Once the onions are caramelized nicely, sprinkle in salt and pepper to taste while stirring well. This step enhances their sweetness beautifully while creating layers of flavor.

Pour in Broth: Next up, pour in your beef broth slowly while scraping up any tasty bits stuck to the pot’s bottom. Bring everything to a gentle simmer—let those flavors mingle for about 15-20 minutes.

Prepare Your Bread and Cheese Topping: While your soup simmers away happily, slice your baguette into thick rounds (about 1 inch). Toast them lightly on both sides until golden brown—this helps prevent sogginess later. Now it’s time to grate that gruyère cheese!

Assemble Your Bowls: Ladle hot soup into oven-safe bowls or crocks. Top each bowl generously with toasted baguette slices followed by heaps of grated cheese—don’t be shy here!

Bake It Up!: Preheat your oven to broil mode (around 500°F or 260°C). Place bowls on a baking sheet lined with foil (for easy cleanup) and slide them under the broiler until the cheese bubbles and turns golden brown—keep an eye on them so they don’t burn!

As you pull out those steamy bowls of heaven from your oven, let them cool slightly before diving in; trust me—your taste buds will thank you later!

Now that you’re equipped with this fabulous recipe for french onion soup, you’re ready to impress family or even just treat yourself! Enjoy every cheesy bite!
