Outback Steakhouse Walkabout Onion Soup is one of my favorite comfort soups to make at home. I love its creamy, savory flavor with the sweetness of sautéed onions and the richness of melted cheese. It’s cozy, hearty, and feels like a warm hug in a bowl. This homemade version tastes just as good as the restaurant classic — maybe even better.

Why You’ll Love This Recipe

I love this recipe because it’s simple, comforting, and budget-friendly. The onions caramelize beautifully, creating a naturally sweet depth of flavor that blends perfectly with the creamy, cheesy broth. It’s an easy soup that feels special enough to serve for guests but is quick enough for a weeknight dinner. I often make it when I want something soothing and filling on a cold day.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

Yellow onions, thinly sliced
Butter
All-purpose flour
Chicken broth
Half-and-half or whole milk
Shredded Velveeta or cheddar cheese
Salt
Black pepper
Garlic powder
Paprika (optional)
Croutons or toasted bread (for topping)

Directions

I start by melting butter in a large saucepan over medium heat.
I add the sliced onions and cook slowly for 15–20 minutes, stirring occasionally, until they turn soft and golden brown.
I sprinkle the flour over the onions and stir for a minute to create a roux.
I gradually pour in the chicken broth while stirring, making sure there are no lumps.
Once the mixture thickens slightly, I add the half-and-half, salt, pepper, garlic powder, and paprika.
I reduce the heat to low and stir in the shredded cheese until smooth and creamy.
I let the soup simmer for about 10 minutes, stirring occasionally, until it’s rich and velvety.
I ladle it into bowls and top each one with extra cheese, croutons, or a slice of toasted bread for that perfect finishing touch.

Servings and Timing

This recipe serves about 4 people. The prep time takes around 10 minutes, and cooking takes about 30 minutes total.

Variations

Sometimes I use a mix of cheeses like cheddar and Monterey Jack for a sharper flavor. For a lighter version, I substitute evaporated milk or low-fat milk instead of half-and-half. If I want to make it extra indulgent, I top it with a handful of shredded cheese and broil it for a minute until bubbly and golden, similar to a French onion soup style.

Storage/Reheating

I store leftover soup in an airtight container in the fridge for up to 3 days. When reheating, I warm it gently on the stove over low heat, stirring frequently so the cheese doesn’t separate. I avoid boiling it once the dairy is added. It also freezes well — I let it cool completely, freeze it in portions, and reheat it slowly when ready to serve.

FAQs

What kind of onions work best?

I prefer yellow onions for their natural sweetness, but white onions also work well for a milder flavor.

Can I make this soup vegetarian?

Yes, I replace the chicken broth with vegetable broth and use vegetarian cheese. It’s just as creamy and delicious.

Can I use fresh cheese instead of processed cheese?

Absolutely. Sharp cheddar or a mix of cheddar and Swiss melts beautifully and adds a more pronounced flavor.

How can I make it thicker?

I add an extra tablespoon of flour during the roux step or simmer it a few minutes longer to reduce the liquid.

What can I serve with this soup?

I love serving it with crusty bread, a green salad, or even alongside a steak for a restaurant-style meal.

Outback Steakhouse Walkabout Onion Soup is the ultimate comfort food — rich, creamy, and full of caramelized onion goodness. I love how easy it is to make and how every spoonful feels so satisfying. It’s cozy enough for a simple dinner yet special enough for entertaining. Whether I serve it as a starter or main course, this soup always brings warmth and smiles to the table.
