Description
A foolproof, beginner-friendly French onion soup recipe that delivers restaurant-quality depth of flavor using just six core ingredients. This comforting dish features deeply caramelized onions, rich beef broth, and a cheesy Gruyère topping, all made in one pot for minimal cleanup.
Ingredients
- 6 large yellow onions (about 3 lbs / 1.4 kg), sliced into half-moons
- 4 tablespoons unsalted butter
- 1 teaspoon granulated sugar
- 4 cloves garlic, minced
- 1 teaspoon dried thyme
- 1/2 cup dry white wine (such as Pinot Grigio or Sauvignon Blanc)
- 4 cups low-sodium beef broth
- 1 tablespoon soy sauce
- Salt and black pepper, to taste
- 6 slices French bread or baguette (about 1/2 inch thick)
- 2 cups Gruyère cheese, shredded
Instructions
- Prep ingredients: Peel and slice onions into 1/4-inch thick half-moons. Mince garlic, measure butter, sugar, and spices. Shred Gruyère cheese and slice bread.
- Sauté onions: Melt butter in a large Dutch oven over medium heat. Add onions and sugar, stirring to coat. Cook for 10 minutes until softened.
- Caramelize: Reduce heat to medium-low. Cook onions for 35-45 minutes, stirring every 5-10 minutes, until deep golden brown and sweet. Deglaze with a splash of water or broth if sticking occurs.
- Build soup: Add minced garlic and dried thyme to the onions; cook for 1 minute until fragrant. Pour in white wine to deglaze, scraping up browned bits, and simmer for 2 minutes.
- Simmer: Add beef broth and soy sauce. Stir to combine and bring to a gentle simmer. Cook for 5-7 minutes to meld flavors. Taste and adjust seasoning with salt and pepper.
- Preheat broiler: While soup simmers, preheat broiler to high. Arrange bread slices on a baking sheet or keep ready.
- Assemble: Ladle hot soup into broiler-safe bowls. Top each with a slice of bread and generously sprinkle with shredded Gruyère cheese.
- Broil: Place bowls on a baking sheet and broil for 2-4 minutes, watching closely, until cheese is melted, bubbly, and golden brown.
- Serve: Serve immediately, allowing soup to cool slightly before eating.
Notes
[‘Do not rush the onions; low and slow cooking is essential for proper caramelization.’, ‘Shred your own cheese to avoid anti-caking agents that prevent smooth melting.’, ‘Soy sauce adds umami depth without making the soup taste Asian.’, ‘Soup base can be made ahead and refrigerated for up to 3 days or frozen for 3 months (without bread and cheese topping).’, ‘If using red wine, reduce amount to 1/4 cup to avoid overpowering flavor.’, ‘For gluten-free version, use gluten-free bread and ensure broth/soy sauce are certified gluten-free.’]
