Jamie Oliver’s version of English onion soup takes inspiration from the French classic but incorporates British flavors with Worcestershire sauce and English cheddar. The onions are caramelized slowly to develop a deep, sweet flavor, then simmered in a rich stock before being topped with crusty bread and cheese for a deliciously golden, bubbly finish.
Caramelize the onions: Melt the butter and olive oil in a large pot over medium-low heat. Add the sliced onions and cook slowly for 30-40 minutes, stirring occasionally, until deep golden brown and caramelized.
Add garlic and herbs: Stir in the minced garlic, thyme, and bay leaf. Cook for another minute until fragrant.
Deglaze with wine: Pour in the white wine (if using) and scrape up any browned bits from the bottom of the pot. Let it simmer for 2-3 minutes until the alcohol evaporates.
Add Worcestershire sauce and stock: Stir in the Worcestershire sauce and pour in the beef or vegetable stock. Season with salt and pepper. Bring to a gentle simmer and let it cook for another 20 minutes to allow the flavors to meld.
Prepare the bread topping: While the soup simmers, toast the baguette slices until crispy.
Assemble and broil: Preheat your oven’s grill/broiler. Ladle the soup into oven-safe bowls, place a toasted baguette slice on top of each, and sprinkle generously with grated cheese.
Melt the cheese: Place the bowls under the broiler for 2-3 minutes, or until the cheese is bubbling and golden brown.
Serve: Remove from the oven carefully and serve immediately with extra bread on the side.
