How to Make Outback Steakhouse Walkabout Onion Soup

Step 1: Caramelize the Onions

Start by melting butter in a large skillet over medium heat. Add thinly sliced yellow onions and cook slowly, stirring frequently, until they become deeply golden brown and sweetly caramelized. This process usually takes around 30-40 minutes but is key to unlocking the soup’s rich flavor.

Step 2: Prepare the Broth Base

Sprinkle in flour and stir to coat the onions, cooking for another minute to remove any raw flour taste. Gradually pour in beef broth while stirring to avoid lumps. Add Worcestershire sauce, minced garlic, salt, and pepper. Bring the mixture to a gentle simmer.

Step 3: Simmer and Blend Flavors

Let the soup simmer for 20-30 minutes, occasionally stirring to meld all the flavors and thicken the broth nicely. This slow simmer develops the savory richness that makes Outback Steakhouse Walkabout Onion Soup so beloved.

Step 4: Toast the Bread

Slice bread and lightly toast it with butter until golden and crispy. This step ensures the bread holds up under the soup and becomes delectably crunchy.

Step 5: Assemble and Broil

Ladle the hot soup into oven-safe bowls, float a toasted bread slice on top of each, then cover generously with shredded mozzarella cheese. Place the bowls under a broiler for 2-4 minutes until the cheese is bubbly and golden.

Pro Tips for Making Outback Steakhouse Walkabout Onion Soup

• Take Your Time: Patience during caramelizing onions is essential for deep flavor development, so don’t rush this step.
• Use Quality Broth: Opt for a well-flavored beef broth or homemade stock to elevate the soup’s richness.
• Thin Onion Slices: Slice onions uniformly thin for even caramelization and a soft, silky texture.
• Broil Carefully: Watch the soup closely under the broiler to avoid burning the cheese or bread.
• Warm the Bowls: Pre-warming bowls prevents the soup from cooling down too fast when served.

How to Serve Outback Steakhouse Walkabout Onion Soup

Garnishes

Fresh chopped parsley or chives sprinkled on top add a pop of color and gentle herbaceous notes that brighten the soup. A light dusting of cracked black pepper enhances the aroma just before serving.

Side Dishes

This soup pairs beautifully with a crisp green salad or a fresh baguette to soak up every bit of the broth and melted cheese. For a heartier meal, serve alongside a grilled steak or roasted vegetables to complement the savory flavors.

Creative Ways to Present

Serve the soup in rustic ceramic bowls for that classic steakhouse feel or use mini cast iron pots to impress guests with individual servings. Adding a drizzle of truffle oil on top elevates the experience with a subtle, luxurious aroma.

Make Ahead and Storage

Storing Leftovers

Store any leftover Outback Steakhouse Walkabout Onion Soup in an airtight container in the refrigerator for up to 3 days. Keep the toasted bread and cheese separately to maintain their texture until ready to reheat and serve.

This soup freezes well without bread or cheese. Transfer cooled soup to freezer-safe containers, leaving some space for expansion, and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.

Reheating

Gently reheat the soup on the stovetop over low heat, stirring occasionally. Add toasted bread and fresh cheese just before serving to maintain the delicious contrast in textures.
