Big, spoon-coating potato soup is all about getting the texture right, and this copycat version lands in that sweet spot where it feels rich and hearty without turning gluey or flat. The potatoes stay present in the bowl, but enough of them are mashed in to give the broth that thick, restaurant-style body people expect from Outback’s version. The toppings matter just as much as the soup itself, because the cold sour cream, sharp cheddar, smoky bacon, and chives hit every spoonful in layers.
What makes this one work is the base: a flour-butter roux cooked long enough to lose that raw taste, then milk, cream, and broth whisked in gradually so the soup stays smooth. The baked potatoes are added after the soup thickens, which keeps them from breaking down completely and turning the whole pot into mashed potatoes. Stirring the cheddar and sour cream off the heat helps the dairy melt in cleanly instead of grainying or separating.
Below, I’ve included the details that matter most — how to keep the soup silky, how much to mash the potatoes, and the best way to reheat it without losing that creamy finish.
The soup turned out thick and creamy without being heavy, and mashing some of the potatoes right in gave it that perfect Outback-style texture. My husband kept going back for another bowl, and the bacon on top kept it tasting fresh instead of one-note.
Save this Outback-style baked potato soup for the nights when you want a thick, cheesy bowl with crispy bacon and barely any fuss.
The Potato Choice That Makes This Soup Taste Like the Restaurant Version
Russet potatoes are the right call here because they break down in a way that makes the soup thick and fluffy without going past the line into gluey. Waxy potatoes hold their shape too well and never give you that baked-potato-meets-cream-soup texture. Baking the potatoes first matters more than it looks like it should, because that dry, fluffy interior gives the soup a deeper potato flavor than boiling ever will.
The bacon does more than garnish the top. A few spoonfuls stirred into the pot bring smoky saltiness into the base, and the rest can stay crisp for serving. If your soup tastes a little flat, it usually means the potatoes needed more salt than you thought or the broth was too mild.
What Each Ingredient Is Actually Doing in This Soup
- Russet potatoes — These give the soup its baked-potato body. Bake them until fully tender, then peel and chop while they’re cool enough to handle. A few mashed chunks help thicken the soup naturally; leave some pieces intact so the bowl still eats like potato soup, not puree.
- Butter and flour — This roux is what keeps the dairy from feeling thin. Cook it for the full 2 minutes so the soup won’t taste raw. If you skip that step, the finished pot can taste pasty instead of rich.
- Whole milk and heavy cream — Whole milk builds the base, while cream gives the soup its restaurant-style richness. You can use half-and-half in place of the cream, but the soup will be a little lighter and less luxurious. Keep the heat moderate so the dairy thickens smoothly instead of scorching.
- Cheddar and sour cream — Add both after the soup has thickened and the heat is lower. Cheddar brings sharpness, and sour cream gives the tang that makes this taste like a loaded baked potato in spoon form. If the soup is boiling when they go in, the dairy can turn grainy.
- Chicken broth — This keeps the soup from tasting like straight milk and potato. It adds savory depth without making the flavor chicken-heavy. Vegetable broth works in a pinch, but the soup will taste a little softer.
- Bacon, chives, and extra toppings — These aren’t decoration. They give every bowl salt, smoke, fresh onion bite, and texture against the creamy base. Don’t bury them in the pot; keep most of them for serving so the contrast stays sharp.
Building the Soup Base Without Letting It Turn Grainy
Cooking the Roux
Melt the butter over medium heat, then whisk in the flour until you’ve got a smooth paste that smells a little nutty, not raw. That 2-minute cook time matters because it takes the floury edge off and gives the soup a clean finish. If the roux clumps, your heat is too high or the butter isn’t fully melted before the flour goes in.
Whisking in the Dairy
Pour in the milk, cream, and broth gradually while whisking constantly. The goal is a smooth base with no lumps, and the easiest way to lose that is dumping in cold liquid too fast. Keep the soup at a gentle simmer, not a hard boil, and stir often so the bottom doesn’t catch.
Thickening and Adding the Potatoes
Let the soup cook until it coats a spoon and leaves a visible trail when you drag a spatula through it, about 8 to 10 minutes. Then fold in the chopped baked potatoes and mash some of them against the side of the pot with the back of a spoon. That partial mash is what gives the soup its thick, hearty body without making it pasty.
Finishing the Cheese and Sour Cream
Take the pot off the heat before stirring in the cheddar and sour cream. Residual heat is enough to melt the cheese and smooth out the sour cream, and pulling the pot off the burner helps prevent separation. Season at the end with salt, pepper, and garlic powder, then taste again before serving because the bacon and cheddar add their own saltiness.
How to Adapt This for a Lighter Bowl or a Bigger Crowd
Dairy-Free Version
Swap the butter for a neutral plant-based butter, use unsweetened oat milk or cashew milk in place of the whole milk, and replace the cream with canned coconut milk or a dairy-free cooking cream. The soup will still thicken, but it won’t taste as sharp or tangy unless you add a little more salt and a splash of acid like lemon juice at the end.
Gluten-Free Swap
Use a measure-for-measure gluten-free flour blend in the roux, or thicken the soup with a cornstarch slurry instead. The texture will still be creamy, but a cornstarch-thickened version sets a little more sharply than the original flour base.
Extra-Hearty Loaded Potato Soup
Stir in an extra half cup of cheddar and a few more chopped potatoes if you want a thicker, more filling pot. The tradeoff is that the soup becomes more casserole-like, so loosen it with a splash of milk if it sits and tightens up on the stove.
Storage and Reheating
- Refrigerator: Store in an airtight container for up to 4 days. It will thicken as it chills.
- Freezer: It can be frozen, but the dairy may separate a bit when thawed. For the best texture, freeze before adding the sour cream and cheddar, then stir those in after reheating.
- Reheating: Warm it slowly on the stove over low heat, stirring often. Don’t boil it, or the dairy can split and the potatoes can turn grainy. Add a splash of milk if it has thickened too much in the fridge.
