how to make Outback Steakhouse Walkabout Onion Soup

Ingredients:

4 large onions, thinly sliced
4 tablespoons unsalted butter
1 teaspoon sugar
3 cups beef broth
1 tablespoon soy sauce
1 tablespoon Worcestershire sauce
1 teaspoon salt
½ teaspoon black pepper
1 cup Gruyère cheese, shredded
Crusty bread for serving

Directions:

In a large pot, melt the butter over medium heat.
Add the thinly sliced onions and cook, stirring frequently. After about 10 minutes, add the sugar to help with caramelization. Continue cooking until the onions are golden brown and tender, around 20 minutes total.
Stir in the beef broth, soy sauce, Worcestershire sauce, salt, and black pepper. Bring everything to a boil and then reduce the heat. Let it simmer for about 20 minutes to allow the flavors to blend.
Preheat your oven to broil. While waiting for the oven, ladle soup into oven-safe bowls and top each with a slice of crusty bread. Pile on the shredded cheese generously atop the bread.
Place the bowls under the broiler for about 2-3 minutes, or until the cheese is bubbly and golden brown. Keep a close eye to ensure they don’t burn.
Carefully remove from the oven and let them cool slightly. Serve with additional crusty bread and savor every bite!

how to serve Outback Steakhouse Walkabout Onion Soup

Serve the soup hot, ideally straight from the oven. The melted cheese should be bubbling, and the crusty bread on top offers a delightful crunch. It’s wonderful as a starter before a main meal or as a warming snack on its own.

how to store Outback Steakhouse Walkabout Onion Soup

If you have leftovers, let the soup cool completely before storing. Place it in an airtight container and keep it in the refrigerator for up to 3 days. Reheat gently on the stove or in the microwave. Avoid reheating it in the oven since the bread and cheese topping might not stay as crispy.

tips to make Outback Steakhouse Walkabout Onion Soup

Use sweeter onions like Vidalia or Walla Walla for a milder taste.
Feel free to customize the cheese. If Gruyère isn’t available, Swiss cheese or mozzarella can also work well.
For extra flavor, add some fresh herbs like thyme or rosemary while simmering the soup.

You can make a vegetarian version of this soup by replacing beef broth with vegetable broth. This way, you still enjoy hearty flavors without meat.

FAQs

1. Can I make this soup ahead of time?
Yes, you can prepare the soup a day in advance. Just store it in the fridge and reheat before serving. Add the cheese and bread just before broiling.

2. What type of bread should I use?
Crusty bread like a baguette or sourdough works best. Make sure it’s thick enough to hold up to the soup and cheese!

3. Can I freeze this soup?
While you can freeze the soup base, avoid freezing the bread and cheese. They don’t reheat well. Store the soup in an airtight container for up to 3 months and reheat when ready to serve.
