The Complete Recipe
Thank you for sticking with me through this delicious journey! Now, let’s get to the good stuff – the recipe itself. You’re going to love making this!
French Onion Soup with Rich Caramelized Onions
Ingredients
- 4 large yellow onions, thinly sliced
- 4 tablespoons unsalted butter
- 1 tablespoon olive oil
- 1 teaspoon sugar (to aid caramelization)
- 8 cups beef broth
- 1 cup dry white wine (optional)
- 2 tablespoons all-purpose flour
- Salt and pepper, to taste
- 1 baguette, sliced
- 2 cups shredded Gruyère cheese
Tip: For a deeper flavor, try using low-sodium broth and adding fresh herbs like thyme or bay leaves during simmering.
Step-by-Step Instructions
Step 1: Caramelize the Onions
In a large pot, melt the butter and olive oil over medium heat. Add the sliced onions and sugar, stirring to coat. Cook for about 30-40 minutes, stirring occasionally. You want them to become golden brown and sweet, not burned. The magic is in this step, so take your time!
Step 2: Add the Flour
Once the onions are caramelized, sprinkle the flour over them. Stir well to combine, cooking for about 2 minutes. This will help thicken the soup later. You want to ensure there are no lumps!
Step 3: Deglaze the Pot
If you’re using wine, pour it in now. Scrape up any brown bits stuck to the bottom of the pot – that’s flavor! Let it simmer for about 5 minutes until slightly reduced. If not using wine, skip to the next step.
Step 4: Add the Broth
Pour in the beef broth, and season with salt and pepper. Bring the mixture to a simmer and let it cook for about 20-30 minutes. This allows the flavors to meld beautifully.
Step 5: Toast the Bread
While the soup is simmering, preheat your oven to 375°F (190°C). Place the baguette slices on a baking sheet and toast them until golden brown, about 10-15 minutes. This will add a delightful crunch to your soup!
Step 6: Assemble and Broil
When the soup is ready, ladle it into oven-safe bowls, top with toasted baguette slices, and generously sprinkle with Gruyère cheese. Place the bowls on a baking sheet and broil in the oven until the cheese is bubbly and golden, about 3-5 minutes. Keep a close eye on them!
Step 7: Serve and Enjoy!
Carefully remove the bowls from the oven and let them cool slightly. Serve hot and watch everyone’s faces light up with joy. This is the moment you’ve been waiting for!
