Copycat Outback baked potato soup lands on the table thick, creamy, and loaded the way a good steakhouse soup should be. The broth clings to the spoon instead of running off it, the potatoes stay hearty, and the bacon, cheddar, and chives on top give every bite that familiar baked-potato finish. It tastes indulgent without being fussy, which is exactly why it earns repeat requests.
The trick is building a real roux first, then whisking in the milk, cream, and broth slowly enough that the base stays silky. Baked russet potatoes do the heavy lifting here because they’re dry and fluffy, which means they break down into the soup without turning it gluey. I also mash a few pieces right in the pot. That gives you the thick, restaurant-style body without needing extra flour.
Below, I’ve included the detail that matters most: how to keep the dairy smooth when the soup thickens, plus the best way to adjust the texture if you want it even thicker. The little finishing choices matter here more than they do in a lot of soups.
The soup thickened up exactly like the restaurant version, and the sour cream stayed smooth instead of curdling. I added a little extra bacon on top and my husband said it was better than Outback.
Save this Outback-style baked potato soup for the nights when you want a thick, cheesy bowl with crispy bacon and almost no fuss.
The Roux Is What Keeps This Soup Thick Instead of Thin
A lot of potato soups lean on extra broth or too much milk, and that’s how they end up tasting bland and looking watery. The butter-and-flour base here gives the soup body before the dairy goes in, so the finished texture stays creamy even after the potatoes are folded through. If the roux is undercooked, the soup can taste floury. Two minutes in the pot takes that raw edge off and sets you up for a smooth finish.
The other mistake is rushing the liquid. When milk and cream hit a hot roux all at once, you can end up with little lumps that never fully disappear. Pour in gradually and whisk as you go. The mixture should look loose at first, then thicken into a base that lightly coats the back of a spoon before the potatoes and cheese ever enter the pot.
What Each Ingredient Is Actually Doing in This Bowl
- Russet potatoes — These are the right potato for this soup because they bake up dry and fluffy, which helps the soup thicken naturally when you mash a few pieces in. Waxy potatoes stay firmer and won’t give you the same body.
- Bacon — Cook it until crisp so it stays snappy on top. You can use thick-cut bacon, but it needs a little more time in the pan to render out enough fat and get crisp enough to stand up to the soup.
- Whole milk and heavy cream — This combination gives the soup its steakhouse richness without making it taste greasy. If you swap in low-fat milk, the soup will be thinner and less plush, though it will still work.
- Cheddar cheese — Shred it yourself if you can. Pre-shredded cheese carries anti-caking starches that can make the soup a little grainy when it melts.
- Sour cream — This adds the signature tang that makes the soup taste like a baked potato instead of a plain cream soup. Stir it in off the heat or over very low heat so it stays smooth.
- Chicken broth — Just enough broth keeps the soup from tasting heavy and flat. It should support the dairy, not take over the flavor.
The 20 Minutes That Turn Potatoes Into Soup
Building the Base
Melt the butter in a large pot over medium heat, then whisk in the flour and let it cook for about two minutes. You want it to look like a pale paste and smell faintly nutty, not raw or pasty. If the heat is too high, the roux can darken too fast and the soup will pick up a scorched taste before the dairy even goes in.
Whisking in the Dairy
Slowly add the milk, cream, and broth while whisking constantly. The mixture may look a little loose at first, then it will turn smooth and slightly glossy as it heats. Keep stirring as it thickens so nothing catches on the bottom of the pot. If you walk away here, the dairy can scorch and leave a thin, burned layer underneath.
Adding the Potatoes
Fold in the chopped baked potatoes, then mash some of them against the side of the pot with your spoon or a potato masher. That’s what gives the soup its thick, rustic texture. Leave some chunks intact so it still eats like baked potato soup and not like gravy. If you mash every piece completely, the texture can turn heavy and pasty.
Finishing with Cheese and Sour Cream
Turn the heat down before you add the cheddar and sour cream. Stir until the cheese melts and the soup looks smooth, then season with salt, pepper, and garlic powder. If the soup is bubbling hard when the sour cream goes in, it can separate. Low heat keeps the texture silky and lets the tang stay clean.
How to Adapt This for Different Kitchens and Different Leftovers
Gluten-Free Version
Swap the all-purpose flour for a 1:1 gluten-free flour blend. The texture stays close to the original because the flour is only here to thicken the base, not build structure. Whisk it well into the butter and cook it the same way so you don’t end up with a starchy taste.
Lighter But Still Creamy
Use half-and-half in place of the heavy cream if you want a slightly lighter soup. It won’t be quite as lush, but the roux and potatoes still keep it thick. I wouldn’t drop to skim or low-fat milk, because the soup loses that restaurant-style body fast.
Vegetarian Version
Skip the bacon and use vegetable broth instead of chicken broth. The soup will still be rich from the butter, milk, cream, cheese, and sour cream, but it will lose the smoky edge the bacon brings. Smoked paprika can help replace some of that depth if you want a little more background flavor.
Storage and Reheating
- Refrigerator: Store in an airtight container for up to 4 days. It thickens as it chills, so expect a denser texture the next day.
- Freezer: It can be frozen, but the dairy may separate a little when reheated. Freeze in portions and thaw overnight in the refrigerator for the best results.
- Reheating: Warm it gently over low heat, stirring often. Don’t boil it, or the sour cream and cheese can split. Add a splash of milk or broth if it gets too thick.
