This Copycat Outback Steakhouse Walkabout Soup is for anyone who remembers that creamy onion soup and wants the same cozy bowl without waiting for it to come back on a menu. It is rich, mild, and full of soft sweet onions rather than browned French onion flavor.
The soup works because the onions are cooked until tender but not dark, then folded into a thick white sauce with broth and cheese. It tastes like a steakhouse starter, but it is easy enough for a cold weeknight.
The creamy onion lineup
Use sweet yellow onions if you can find them. They soften into the soup without the sharp bite you get from stronger onions.
Whole milk, butter, and melty cheese give the soup its smooth body. Low-sodium broth helps you control the final seasoning.
- Sweet yellow onions. They bring the gentle onion flavor that makes this soup taste familiar and mild.
- Butter. Softens the onions and forms the base of the roux.
- All-purpose flour. Thickens the milk so the soup feels creamy instead of thin.
- Whole milk. Gives the white sauce body and a soft dairy richness.
- Chicken broth. Loosens the sauce and adds savory depth.
- Chicken bouillon. Adds the stronger steakhouse-style seasoning in a small amount.
- Velveeta and cheddar. Melt into a smooth, cheesy finish without turning stringy.
- Green onion. Adds a fresh bite on top of the finished bowl.
Copycat Outback Steakhouse Walkabout Soup Method
- Soften the onions. Cook sliced sweet onions in butter over medium-low heat until tender and translucent. Stir often and do not brown them.
- Build the broth base. Add chicken broth, bouillon, salt, pepper, and a pinch of paprika. Keep it warm while you make the white sauce.
- Make the roux. Melt butter in a second saucepan, whisk in flour, and cook for about 1 minute. Slowly whisk in milk until thick and smooth.
- Combine the pots. Stir the white sauce into the onion broth a little at a time. Keep the heat gentle so the dairy stays smooth.
- Melt the cheese. Add Velveeta and cheddar off the highest heat, stirring until creamy. Simmer gently for 15-20 minutes.
- Finish the bowls. Taste for salt and pepper, then serve hot with shredded cheddar, green onion, and bread.
Keep the onions pale
The biggest difference between this soup and a deeper onion soup is color. You are not caramelizing the onions. Cook them slowly until they look glossy, soft, and almost clear. If they brown hard around the edges, the soup leans toward French onion and loses the mild steakhouse flavor.
A medium-low burner is your friend here. Stir every minute or two and give the onions enough time to slump down. If the pan looks dry, add a small knob of butter instead of turning up the heat. For a darker onion soup mood, save that technique for Classic Crockpot French Onion Soup. For this bowl, pale onions are the whole point. You can also compare it with the site's Outback Walkabout Soup if you want another cozy copycat take.
Make the roux behave
The white sauce is what gives Walkabout Soup its spoon-coating texture. Melt the butter, whisk in the flour, and let it cook just long enough to lose the raw flour smell. Then add the milk slowly. A splash at first will look too thick, but keep whisking and it will loosen into a smooth sauce.
If you dump in all the milk at once, lumps are more likely. If you walk away, the bottom can scorch. Keep the heat at medium and whisk until the sauce looks like loose pudding. That texture means it is ready to join the onion broth. This same gentle dairy logic is useful in other creamy bowls, especially Cheddar Cauliflower and Roasted Garlic Soup, where cheese and milk need calm heat to stay silky.
Cheese goes in gently
Velveeta is not fancy, but it melts cleanly and gives this soup the smooth copycat texture people remember. A small amount is enough. I like adding a little cheddar too, because it gives the soup a sharper finish without making it greasy.
Take the pan down to low before the cheese goes in. Stir in small pieces and let each handful melt before adding more. Do not boil the soup after this point. Boiling dairy and cheese can make the soup look broken or grainy. If the soup gets too thick while it sits, thin it with a splash of warm milk or broth. For another comfort bowl with that creamy steakhouse feel, Baked Potato Soup is a natural next stop.
Serving and storing it
This soup is best served hot, right after the cheese melts in. Spoon it into warm bowls and finish with cheddar, sliced green onion, and black pepper. Dark bread is very good here because it balances the sweet onions and dairy. A crisp salad helps if you are serving it before a heavier dinner.
Leftovers keep well in the fridge for up to 3 days. Cool the soup, cover it, and reheat it over low heat with a splash of milk or broth. Stir often and stop as soon as it is hot. The USDA has clear leftover food-safety guidance if you want timing details. I do not love freezing this one. The dairy base can split when thawed.
Summary
Serve this soup hot with shredded cheddar, green onion, and dark bread or a crisp salad.
FAQs
- What is Walkabout Soup?
Walkabout Soup is a creamy onion soup inspired by the former Outback Steakhouse menu item. It is not a dark French onion soup. The onions stay pale and sweet, and the broth is thickened with a buttery white sauce.
- Can I make it without Velveeta?
Yes, but the texture changes. Velveeta melts very smoothly, which helps the soup taste close to the restaurant-style version. If you skip it, use mild cheddar and add it off the heat in small handfuls.
- Can I use vegetable broth?
You can use vegetable broth for a meatless version. Choose a mild broth so it does not cover the onion flavor. You may need a little extra salt because chicken bouillon brings more savory depth.
- Why did my soup turn grainy?
Graininess usually comes from heat that is too high after the cheese goes in. Lower the burner before adding cheese and stir until just melted. Do not let the soup boil once the dairy is added.
- How long do leftovers keep?
Refrigerate leftovers in an airtight container for up to 3 days. Reheat slowly on the stove with a splash of milk or broth. Freezing is not ideal because the dairy base can separate.
- What should I serve with it?
Dark bread, a baked potato, a wedge salad, or a simple grilled steak all fit the steakhouse mood. For a lighter meal, pair it with roasted vegetables or a crisp green salad.
