History of French Onion Soup & Walkabout Twist

French onion soup originated in 18th-century France as a simple peasant dish. Caramelized onions, rich beef broth, and toasted bread with melted cheese made it hearty and affordable. Over time, restaurants like Outback Steakhouse put their spin on it, creating the Walkabout Onion Soup — slightly sweeter, richer, and topped with a bubbling crown of Swiss cheese for an unforgettable presentation.

This version honors that tradition while being approachable for home cooks. With simple ingredients and a little patience in caramelizing the onions, you can achieve that restaurant-style depth of flavor in your own kitchen.

Ingredients

For the Soup:

• 4 large yellow onions, thinly sliced
• 4 tablespoons unsalted butter
• 2 tablespoons olive oil
• 1 teaspoon sugar
• 2 tablespoons all-purpose flour
• 6 cups beef broth (preferably low-sodium)
• 1 cup dry white wine
• 2 teaspoons Worcestershire sauce
• 1 teaspoon fresh thyme (or ½ tsp dried)
• Salt and black pepper, to taste

For the Topping:

• 1 French baguette, sliced into ½-inch rounds
• 2 cups shredded Swiss cheese (or Gruyère for extra richness)
• 1 tablespoon olive oil (for brushing bread)

Instructions

Step 1: Caramelize the Onions
In a large heavy-bottomed pot, heat butter and olive oil over medium heat. Add sliced onions and sugar, stirring occasionally. Cook for 30–40 minutes until onions are deeply golden brown and sweetly caramelized.

Step 2: Add Flour
Sprinkle flour over the onions and stir for 1–2 minutes. This will thicken the soup slightly.

Step 3: Deglaze with Wine
Pour in the white wine, scraping the bottom of the pot to release all caramelized bits. Let it simmer for 3–4 minutes to reduce slightly.

Step 4: Add Broth & Seasonings
Add beef broth, Worcestershire sauce, and thyme. Stir well and bring to a gentle simmer. Cook for 20 minutes, allowing the flavors to meld. Season with salt and black pepper to taste.

Step 5: Prepare the Toasted Bread
While the soup simmers, preheat your oven to 375°F (190°C). Brush both sides of baguette slices lightly with olive oil. Toast in the oven for 8–10 minutes until golden and crisp.

Step 6: Assemble and Broil
Ladle soup into oven-safe bowls. Place a toasted baguette round on top of each bowl and cover with a generous amount of shredded Swiss cheese.

Place bowls on a baking sheet and broil in the oven for 2–4 minutes until cheese is melted and bubbly. Watch closely to avoid burning.

Step 7: Serve Immediately
Serve hot, straight from the oven, and enjoy the rich, savory goodness with melted cheese and crisp bread in every spoonful.
