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
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.

- 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.
