2. Ingredients for French Onion Soup with Cheesy Croutons

  • 4 large yellow onions, thinly sliced
  • 3 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 2 teaspoons sugar (to enhance caramelization)
  • 4 cups beef broth (for rich flavor)
  • 1 cup dry white wine (optional but adds depth)
  • 2 bay leaves
  • 1 teaspoon fresh thyme leaves or ½ teaspoon dried thyme
  • Salt and black pepper to taste
  • 1 baguette, sliced into rounds
  • 2 cups shredded Gruyère cheese (or Swiss cheese as a substitute)
  • Fresh parsley for garnish (optional)

3. Step-by-Step Instructions to Make French Onion Soup with Cheesy Croutons

1. Caramelize the Onions

In a large pot, melt the butter with the olive oil over medium heat. Add the sliced onions and cook, stirring frequently, until they become soft and golden brown, about 30-40 minutes. Add the sugar during the last 10 minutes to help achieve a beautiful caramelization. This step is crucial for that signature sweet and savory onion flavor that defines this french onion soup.

2. Deglaze and Simmer

Pour in the white wine (if using) to deglaze the pot, scraping up any browned bits for extra flavor. Add the beef broth, bay leaves, and thyme. Season with salt and pepper. Bring the mixture to a boil, then reduce heat and let it simmer uncovered for about 30 minutes to develop a rich, layered taste.

3. Prepare Cheesy Croutons

While the soup simmers, preheat your oven to 375°F (190°C). Arrange the baguette slices on a baking sheet and toast until lightly golden, about 10 minutes. Remove from oven, sprinkle generously with the Gruyère cheese, and bake until melted and bubbly, about 5 minutes. These cheesy croutons add the perfect crispy, cheesy topping that elevates this comfort food.

4. Assemble and Serve

Remove the bay leaves from the soup. Ladle the hot soup into oven-safe bowls, place a cheesy crouton on top of each, and sprinkle with additional cheese if desired. For an authentic presentation, broil the bowls until the cheese is golden and bubbling. Garnish with fresh parsley and serve immediately for a truly indulgent experience.

4. Storage Tips for French Onion Soup

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm on the stovetop over low heat, adding a splash of beef broth if needed to loosen the soup. Note that this classic soup recipe is best enjoyed fresh when the cheese on the croutons remains crispy — for best texture, re-toast the croutons before serving.

5. Serving Suggestions for French Onion Soup with Cheesy Croutons

Pair this comfort food with a light green salad or roasted vegetables for a balanced meal. For a complete French-inspired dining experience, include some crusty bread or a glass of dry white wine. Check out the green bean casserole for a side dish that complements the richness of this soup.

6. Tips to Make the Perfect French Onion Soup

  • Use yellow onions for their natural sweetness and optimal caramelization.
  • Caramelize the onions slowly to develop deep, complex flavors.
  • Choose a good quality beef broth or homemade for an authentic taste.
  • Broil the cheese-topped croutons for a bubbly, golden finish.
  • Experiment with different cheeses like Fontina or Parmesan for variation.

7. Frequently Asked Questions (FAQs) about French Onion Soup with Cheesy Croutons

What type of onions are best for French onion soup?

Yellow onions are ideal due to their natural sweetness and excellent caramelization properties, but sweet onions or shallots can also be used for a slightly different flavor.

Can I make this soup vegetarian?

Absolutely! Use vegetable broth instead of beef broth and add some sautéed mushrooms or smoked paprika to enhance the depth of flavor.

How do I prevent the cheese from burning during broiling?

Keep a close eye on the soup while broiling and remove it as soon as the cheese is bubbly and golden. You can also lightly cover with foil if the cheese starts to brown too quickly.
