Ingredients You’ll Need
For this recipe, we’ll keep the ingredient list simple. You might already have most of these in your pantry or local supermarket:
- 6 medium-sized yellow onions (sweet or yellow onions work best)
- 4 tablespoons of butter
- 2 tablespoons of olive oil
- 2 cloves of garlic (minced)
- 1 teaspoon of sugar (optional, helps with caramelization)
- Salt and pepper to taste
- 8 cups beef broth (you can use chicken broth or vegetable broth as alternatives)
- 1/4 cup dry white wine (optional for extra flavor)
- 4 slices of baguette (other crusty bread works too)
- 1 cup shredded Gruyère cheese (Swiss or mozzarella can also work)
Step-by-Step Instructions
Step 1: Prepare Your Ingredients
- Peel and thinly slice the onions into half-moons. It may take some time, but slicing the onions evenly ensures they’ll cook properly.
- Mince the garlic and prepare your bread slices.
Step 2: Caramelize the Onions
Caramelized onions are the heart of this soup. Here’s how to get them right:
- Heat the butter and olive oil in a large pot or deep skillet over medium heat.
- Add the sliced onions to the pot and stir them to coat with the butter and oil.
- Sprinkle a pinch of salt and (optionally) sugar over the onions. Stir occasionally as they cook.
- Lower the heat slightly after a few minutes. The goal is to cook the onions slowly to coax out their natural sweetness. This step may take 30–40 minutes. Be patient!
- Once the onions turn golden brown and soft, add the minced garlic. Stir and cook for another minute or two.
Step 3: Build the Soup
Once your onions are caramelized, it’s time to create the broth:
- Add the dry white wine (if using) to the pot. Let it simmer for a few minutes to cook off the alcohol.
- Add the beef broth to the pot, stirring to combine it with the onions.
- Season the soup with salt and pepper to taste. You can adjust based on your preference.
- Bring the soup to a boil, then reduce the heat and let it simmer for 20–30 minutes. This step allows the flavors to blend beautifully.
Step 4: Prepare the Bread and Cheese
The cheesy bread topping makes this soup extra special:
- Preheat your oven’s broiler or a toaster oven. Lay the baguette slices on a baking tray.
- Toast the bread lightly until it’s firm but not completely browned.
- Sprinkle shredded Gruyère cheese generously over each slice of bread.
Step 5: Assemble and Serve
Now comes the fun part—bringing everything together:
- Ladle the hot soup into oven-proof bowls (if you don’t have oven-proof bowls, don’t worry—you can adjust this step).
- Place a slice of cheesy bread on top of each bowl of soup.
- If your bowls are oven-proof, place them in the oven under the broiler for a few minutes, until the cheese is melted and bubbling. If you’re using regular bowls, toast the bread with the cheese separately, then transfer the cheesy slices onto the soup.
- Serve the soup immediately, garnished with a sprinkle of fresh thyme or parsley (optional).
Tips for Success
- Be patient with the onions: Rushing the caramelization process can lead to burnt onions instead of sweet and soft ones.
- Customize the broth: Beef broth gives you the traditional flavor, but chicken or vegetable broth works just fine if that’s what you have.
- Choose the right cheese: Gruyère is the classic choice, but you can experiment with Swiss cheese, mozzarella, or even cheddar.
