How to Make Outback Steakhouse Walkabout Onion Soup

Step 1: Caramelize the Onions

Start by melting butter with olive oil in a large pot over medium heat. Add thinly sliced onions and a pinch of salt, stirring occasionally, until they turn golden brown and sweetly fragrant—this can take up to 40 minutes but is essential for that signature flavor.

Step 2: Add Aromatics and Deglaze

Stir in minced garlic and fresh thyme, cooking for another minute. Then pour in dry white wine, scraping the brown bits from the bottom of the pot to incorporate those rich flavors into the soup base.

Step 3: Pour in Beef Broth and Simmer

Add the beef broth to the pot, bring to a gentle simmer, and let it cook for 20-25 minutes, allowing the flavors to develop and marry beautifully.

Step 4: Prepare the Toasted Bread

While the soup simmers, slice the sourdough bread and toast it until crisp but not overly hard; this will form the perfect base for the melted Gruyère topping.

Step 5: Assemble and Broil

Ladle the soup into oven-safe bowls, place a slice of toasted sourdough on top of each, and generously cover with shredded Gruyère cheese. Pop the bowls under a broiler until the cheese is bubbly and golden brown, about 3-5 minutes.

Pro Tips for Making Outback Steakhouse Walkabout Onion Soup

• Patience is key: Slow caramelization of onions ensures maximum sweetness and depth.
• Use quality broth: A well-flavored beef broth elevates the entire soup.
• Thin, even slices: Cutting onions uniformly helps them cook evenly and beautifully.
• Broil carefully: Keep a close eye on the cheese to avoid burning during the final step.
• Fresh herbs make a difference: Thyme adds an aromatic lift that balances the richness.

How to Serve Outback Steakhouse Walkabout Onion Soup

Garnishes

Sprinkle with a bit of fresh chopped parsley or cracked black pepper to add a fresh, colorful final touch that enhances both presentation and flavor.

Side Dishes

Creative Ways to Present

Serve the soup in mini cast-iron skillets or rustic crockery for an authentic Walkabout experience, or add a twist by topping with caramelized shallots or crispy bacon for extra indulgence.

Make Ahead and Storage

Storing Leftovers

Keep any leftover soup in an airtight container in the refrigerator for up to 3 days. For best texture, store the toasted bread and cheese separately and assemble just before reheating.

Freezing

Scoop the soup (without toppings) into freezer-safe containers and freeze for up to 3 months. Thaw overnight in the fridge before reheating on the stove.

Reheating

Warm the soup gently on the stovetop over medium heat, stirring occasionally. Add toasted bread and cheese afterwards, then broil briefly to re-melt the cheese for the perfect finish.
