Indulge in the rich, deep flavors of this classic French onion soup, where caramelized onions meet a savory broth, topped with a golden, cheesy crust. A perfect blend of simple ingredients, this dish transforms into a warm, comforting bowl of deliciousness.
Ingredients
- 4 pounds yellow onions, peeled and thinly sliced (about 5–6 large onions)
- 3 tablespoons butter (or vegan alternative)
- 4 cloves garlic, minced
- 3 tablespoons flour (use gluten-free if needed)
- ½ cup dry white wine
- 6 cups beef or vegetable stock
- 1 teaspoon Worcestershire sauce
- 1 whole bay leaf
- 3 sprigs fresh thyme (or 1 teaspoon dried thyme)
- Salt & black pepper, to taste
- 1 baguette, sliced for topping
- Gruyère, Asiago, Swiss, Gouda, or Mozzarella cheese, grated or sliced
Instructions
- Caramelize the Onions – Melt butter in a large pot over medium-high heat. Add sliced onions and sauté for 30 minutes, stirring frequently, until deeply caramelized. Stir in minced garlic and cook for 2 more minutes.
- Build the Flavor – Sprinkle in flour, stir for a minute, then pour in the white wine to deglaze the pan. Scrape up any browned bits for extra richness.
- Simmer to Perfection – Add stock, Worcestershire sauce, bay leaf, and thyme. Stir well, bring to a simmer, then reduce heat and let cook for at least 10 minutes. Discard the bay leaf and thyme sprigs. Season with salt and black pepper to taste.
- Prepare the Toasted Topping – Preheat oven to 400°F. Slice the baguette into 1-inch pieces and toast on a baking sheet for 6-8 minutes until golden and crisp.
- Assemble and Broil – Switch oven to broil. Ladle soup into oven-safe bowls, top with toasted baguette slices, and generously layer with cheese. Broil for 2-4 minutes until the cheese is melted and bubbling. Serve immediately.
Notes
- Vegan Option: Use plant-based butter, vegetable broth, and dairy-free cheese.
- Gluten-Free Alternative: Replace flour with gluten-free flour and use gluten-free bread.
- Make Ahead: Caramelized onions can be made in advance and stored in the fridge for up to 3 days.
