Step-by-Step French Onion Soup Instructions
Preparing Your French Onion Soup
This French onion soup recipe is a labor of love, but the results are so worth it. With a prep time of just 15 minutes and a cook time of 45 minutes, you’ll have this comforting masterpiece ready to enjoy in just 60 minutes. You’ll need a large heavy-bottomed pot or Dutch oven to bring this dish to life.
1- Begin by thinly slicing the 3 large yellow onions. The key here is to slice them as evenly as possible so they cook at the same rate.
2- In your pot, melt the 2 tablespoons of unsalted butter with the 1 tablespoon of olive oil over medium heat. Once the butter is foaming, add the sliced onions and stir to coat them evenly in the fat. Cook the onions, stirring occasionally, for about 30-35 minutes, until they’re deeply caramelized and golden brown.
3- Once the onions have reached the perfect level of caramelization, pour in the 4 cups of beef broth and 2 cups of chicken broth. Add the 1/2 cup of dry white wine, 2 teaspoons of fresh thyme leaves, and 1 bay leaf. Bring the soup to a simmer and let it cook for an additional 10-15 minutes, allowing the flavors to meld.
4- As the soup simmers, you’ll notice the broth becoming rich and the onions becoming even more tender and flavorful. The aroma filling your kitchen will be absolutely mouthwatering.
5- To finish, ladle the hot soup into oven-safe bowls and top each one with slices of toasted baguette. Generously sprinkle 2 cups of shredded Gruyère cheese over the top.
6- Place the bowls under the broiler for 2-3 minutes, until the cheese is melted and bubbly. Serve immediately, allowing your guests to savor the caramelized onions, rich broth, and gooey, cheesy goodness.
