Ingredients

For the Soup:

  • 4 large yellow onions (about 2 lbs), thinly sliced
  • 4 tbsp unsalted butter
  • 1 tbsp olive oil
  • 1 tsp kosher salt
  • 1/2 tsp black pepper
  • 1 tsp sugar (optional, to aid caramelization)
  • 2 cloves garlic, minced
  • 1/2 cup dry white wine (e.g., Sauvignon Blanc)
  • 6 cups low-sodium beef broth
  • 1 tbsp Worcestershire sauce
  • 2 sprigs fresh thyme (or 1/2 tsp dried)
  • 1 bay leaf

Topping Ingredients:

  • 8 slices of baguette (1/2-inch thick)
  • 1 1/2 cups shredded Gruyère cheese
  • 1/4 cup grated Parmesan cheese

For Serving:

  • Optional: Fresh thyme sprigs
  • Suggested Accompaniments: Side salad, crusty bread
  • Suggested Pairings: Red wine, sparkling water
  • Suggested Aesthetic: Serve in white ceramic crocks
  • Suggested Equipment: Large pot, oven-safe crocks, baking sheet

Step-by-Step Process

  1. Caramelize Onions: In a large pot over medium heat, melt butter with olive oil. Add sliced onions, salt, pepper, and sugar (if using). Cook, stirring occasionally, for 30-40 minutes until onions are deep golden brown and caramelized. Reduce the heat if browning too quickly.
  2. Add Garlic and Wine: Stir in minced garlic and cook for 1 minute. Add white wine, scraping up browned bits, and simmer for 2-3 minutes until slightly reduced.
  3. Build Soup: Add beef broth, Worcestershire sauce, thyme sprigs, and bay leaf. Bring to a simmer, then reduce heat to low. Cover and simmer for 20-25 minutes to meld flavors. Remove thyme and bay leaf. Taste and adjust salt or pepper.
  4. Prepare Topping: Preheat the oven broiler. Arrange baguette slices on a baking sheet and toast under the broiler for 1-2 minutes per side until golden. Set aside.
  5. Assemble and Broil: Ladle soup into oven-safe white ceramic crocks, filling 3/4 full. Place 1-2 toasted baguette slices on each, then sprinkle generously with Gruyère and Parmesan. Place crocks on a baking sheet and broil for 2-3 minutes until the cheese is melted and bubbly, watching closely to avoid burning.
  6. Serve: Garnish with thyme sprigs. Serve hot in white ceramic crocks with a side salad, crusty bread, and red wine.

Tips for Better French Onion Soup

  • Slice onions thinly and evenly for uniform caramelization.
  • Stir onions occasionally, but let them sit to develop color; low heat prevents burning.
  • Use low-sodium broth to control saltiness, especially with the cheese topping.
  • Choose a dry white wine for deglazing; avoid sweet varieties.
  • Toast the baguette slices well to prevent sogginess in the soup.
  • Broil the cheese topping carefully; it burns quickly under high heat.
  • Use oven-safe crocks for an authentic presentation and safety.
  • Enhance aesthetic: Place the thyme sprig delicately and serve in white ceramic crocks for a rustic look.
Variations and Customization
  • Vegetarian French Onion Soup: Use vegetable broth and omit Worcestershire or use a vegan alternative.
  • Gluten-Free French Onion Soup: Use a gluten-free baguette and ensure the broth is gluten-free.
  • Vegan French Onion Soup: Use vegan butter, vegetable broth, vegan Worcestershire, and vegan cheese.
  • Spicy French Onion Soup: Add 1/4 tsp cayenne or 1 diced chili with garlic.
  • Mushroom French Onion Soup: Add 1 cup sliced mushrooms with onions.
  • Low-Sodium French Onion Soup: Use low-sodium broth and reduce salt to 1/2 tsp.
  • White Onion Soup: Use white onions for a milder flavor.
  • Slow Cooker French Onion Soup: Caramelize onions on the stovetop, then combine all ingredients in a slow cooker; cook on low for 6-8 hours.
Storage and Serving Tips
  • Store soup (without the cheese topping) in an airtight container in the fridge for 4 days.
  • Reheat on the stovetop over medium heat, stirring, or microwave for 1-2 minutes.
  • Freeze soup (without bread or cheese) for 3 months; thaw in the fridge, reheat, and add a fresh topping.
  • Serve hot for the best texture; cold soup is thicker.
  • Add fresh bread and cheese topping when reheating for the best results.
  • Don’t leave at room temperature for over 2 hours.
  • Pair with light sides, like salad, to balance richness.
  • Presented in white ceramic crocks with thyme for elegant charm.
