Rich French Onion Soup with Bone Broth
Just when you think winter can’t get cozier, this rich French onion soup with bone broth proves otherwise. It’s a deeply savory, soul-warming classic made even better with a homemade foundation. The long, slow caramelization is the only secret you need.
Serving: 4 | Pre Time: 15 minutes | Cooking Time: 2 hours 15 minutes
Ingredients
– Yellow onions – 3 lbs
– Unsalted butter – 4 tbsp
– Beef bone broth – 6 cups
– Dry white wine – ½ cup
– Fresh thyme – 4 sprigs
– Bay leaf – 1
– Salt – 1 tsp
– Black pepper – ½ tsp
– Baguette – 4 slices
– Gruyère cheese – 8 oz, shredded
Instructions
1. Peel and thinly slice 3 lbs of yellow onions.
2. Melt 4 tbsp of unsalted butter in a large Dutch oven over medium-low heat.
3. Add all sliced onions to the pot and stir to coat with butter.
4. Cook onions for 45 minutes, stirring every 10 minutes, until they are soft and translucent. (Tip: Do not rush this step; low heat is key for even cooking without burning.)
5. Increase heat to medium and cook for another 45 minutes, stirring every 5 minutes, until onions are deeply browned and caramelized.
6. Pour in ½ cup of dry white wine to deglaze the pot, scraping up any browned bits from the bottom.
7. Add 6 cups of beef bone broth, 4 sprigs of fresh thyme, 1 bay leaf, 1 tsp salt, and ½ tsp black pepper.
8. Bring the soup to a boil, then reduce heat to low and simmer uncovered for 45 minutes. (Tip: Simmering uncovered allows the flavors to concentrate and the soup to reduce slightly.)
9. While soup simmers, preheat your oven’s broiler to high.
10. Place 4 baguette slices on a baking sheet and toast under the broiler for 1-2 minutes per side until golden and crisp.
11. Remove thyme sprigs and bay leaf from the finished soup and discard.
12. Ladle the hot soup into 4 oven-safe bowls placed on a baking sheet.
13. Top each bowl with 1 toasted baguette slice and evenly divide 8 oz of shredded Gruyère cheese over the bread. (Tip: For a perfectly melted, bubbly top, shred the cheese yourself instead of using pre-shredded.)
14. Broil for 3-5 minutes until the cheese is melted, bubbly, and spotty brown.
15. Carefully remove bowls from the oven and let cool for 5 minutes before serving.
Beneath the golden, cheesy crust lies a soup with a velvety, rich texture from the long-simmered bone broth. The deeply caramelized onions provide a sweet, complex base that balances the savory, umami notes perfectly. For a creative twist, serve individual crocks with a small side salad dressed in a sharp vinaigrette to cut through the richness.
