Ingredients
To create this delightful French Onion Soup, you’ll need:
- 2 1/2 lbs beef finger ribs: Juicy and tender, these will form the base of your rich broth.
- 1/2 onion, chopped: Adds a base layer of flavor for the stock.
- 2 large carrots, chopped: Sweet and earthy, complementing the beef wonderfully.
- 2 celery ribs, chopped: Brings a crisp texture and aromatic quality.
- 4 garlic cloves, smashed: Infuses a delightful fragrance into the broth.
- 2 fresh bay leaves: Adds depth to the flavor profile.
- 20 cups water: The foundation of our hearty broth.
- 4 tablespoons unsalted butter: For richness and flavor in caramelizing onions.
- 3 white onions: They caramelize beautifully and add a sweet note.
- 3 yellow onions: Adds complexity to the soup’s flavor.
- 3 garlic cloves, thinly sliced: To amplify the garlic notes.
- 1 tablespoon fresh thyme leaves: Provides a hint of herbal freshness.
- 2 teaspoons Dijon mustard: This elevates the savory complexity.
- 1 tablespoon Worcestershire sauce: Enhances the umami flavors.
- 8 cups beef stock: Rich and savory, the heart of the soup.
- Kosher salt and freshly cracked black pepper: Essential for seasoning.
- 1/2 French baguette, sliced 1 inch thick: Crispy and ideal for toasting.
- 3 tablespoons softened butter: For coating the bread.
- 1 garlic clove: For rubbing on the toasted bread.
- 1 1/2 cups shredded Gruyère cheese: Melts beautifully, adding creaminess.
Step-by-Step Directions
Roast the bones: Begin by lining a baking sheet with foil and placing the beef ribs side by side. Position an oven rack in the top third of the oven and broil the ribs for 12-15 minutes, flipping halfway through, until they are beautifully browned. This step adds a depth of flavor to your stock.
Make the stock: Transfer the roasted bones and any juices to an 8-quart stock pot. Add the chopped onion, carrots, celery, bay leaves, and smashed garlic before pouring in 20 cups of water. Bring everything to a simmer, skimming off any foam that rises to the surface. Allow it to simmer until the liquid reduces by just over half, resulting in 8-10 cups of broth. Once ready, strain the broth through a mesh strainer into mason jars and discard the solids.
Slice the onions: For even cooking, use a mandoline to slice the white and yellow onions into 2 mm thick pieces. Set them aside, as this will be the star of the French onion soup.
Caramelize the onions: In a large Dutch oven, melt the butter over medium heat. Once it’s foamy, add the sliced onions, ensuring they are well-coated. Cover the pot for the first 5 minutes, then uncover, reduce the heat to medium-low, and season lightly with salt and pepper. Stir in the sliced garlic and bay leaves and allow the onions to cook, stirring every 5-10 minutes, until they are deeply golden brown, which typically takes about 45 minutes to an hour.
Season the onions: Once caramelized to perfection, increase the heat to medium and add the Dijon mustard, Worcestershire sauce, and thyme leaves to the onions. When the onions start sizzling, introduce the vermouth and simmer for an additional 5 minutes.
Make the soup: Pour the prepared beef stock into the caramelized onions and bring it to a gentle simmer. Allow it to simmer for 15-20 minutes until slightly thickened. Don’t forget to taste and adjust the seasoning with salt and pepper as needed.
Preheat the oven to 425°F for toasting the toppings.
Toast the bread: Arrange the slices of baguette on a baking sheet, spreading softened butter over each slice. Season with a sprinkle of salt and pepper. Toast them in the oven for about 7-10 minutes, or until golden brown. Once removed, rub each slice with a clove of garlic for an extra flavor boost.
Broil: Finally, ladle the flavorful soup into oven-safe bowls. Top with a slice of the toasted baguette and generously sprinkle shredded Gruyère cheese atop the bread. Place the bowls on a baking sheet and transfer them to the oven for 10 minutes. For a final touch, broil briefly if desired, until the cheese is melted and bubbly.
Tips & Tricks
- Use High-Quality Ingredients: The flavors of your soup rely heavily on the quality of the onions and beef stock, so choose fresh and premium products.
- Patience is Key: Allow the onions to caramelize slowly for that perfect sweetness. Rushing the process can lead to uneven cooking.
- Cheese Variations: While Gruyère is classic, feel free to experiment with Swiss cheese or a mix for a twist.
- Herbs and Spices: Add a dash of cayenne pepper for heat or a sprig of rosemary for a fragrant profile.
- Making Ahead: The soup can be made a day in advance; flavors will deepen and improve when allowed to sit.
Serving Suggestions & Pairings
French Onion Soup is perfect as a starter for a fancy dinner or paired with a light salad for a complete meal. Serve with a side of crusty bread or a simple arugula salad drizzled with lemon vinaigrette. A crisp white wine like Sauvignon Blanc can beautifully complement the flavors.
