Velvety, thick, and loaded with baked potato flavor, this copycat Outback baked potato soup has the kind of creamy body that clings to the spoon and settles into something closer to a meal than a starter. The bacon, cheddar, and sour cream on top aren’t just garnish here; they’re part of the whole restaurant-style experience, right down to the salty bite and the cool finish.
What makes this version work is the way the potatoes are treated. Baking them first gives the soup that deep, dry potato flavor you don’t get from boiling, and mashing a portion of the pieces right into the pot naturally thickens the broth without making it gluey. The flour-butter base gets cooked long enough to lose that raw taste, then the dairy goes in gradually so the soup stays smooth instead of turning grainy or lumpy.
Below, I’ve laid out the little details that matter most: how to keep the soup thick but not pasty, when to stir in the cheese so it melts cleanly, and how to adjust the texture if your potatoes are extra starchy.
The soup got that restaurant-style thickness after about 10 minutes, and I loved that the baked potato chunks stayed intact instead of disappearing. My husband kept going back for more because the bacon and cheddar on top made it taste just like Outback.

The Trick to Keeping This Soup Thick Without Turning It Gluey
The most common mistake with baked potato soup is chasing thickness too early. If you start with too much flour or let the soup boil hard after the dairy goes in, the texture turns heavy and a little pasty instead of creamy. The goal here is a smooth, spoon-coating base with potato pieces that still look like potato.
The baked potatoes do half the thickening for you. Once they’re folded in, mash some of the pieces against the side of the pot, but leave plenty intact. That mix of chunks and starch gives the soup body without making it feel like mashed potatoes in milk.
- Russet potatoes — These are the right choice because they bake up fluffy and starchy, which helps the soup thicken naturally. Yukon golds will work in a pinch, but the texture will be a little denser and less classic.
- Butter and flour — This is the base that keeps the soup stable. Cook the flour for the full 2 minutes so the finished soup tastes rich instead of raw and chalky.
- Whole milk and heavy cream — The combination gives you the restaurant-style body. Lower-fat milk will thin the soup and make the cheese sauce more likely to taste flat.
- Sour cream — Stir it in off the heat or over very low heat so it stays smooth. If you add it to a boiling pot, it can split and leave tiny curds behind.
- Cheddar — Use a good sharp cheddar if you can. Freshly shredded melts better than bagged cheese, which is often coated with anti-caking starch that can make the soup slightly grainy.
Building the Base Before the Cheese Goes In
- Chopped baked potatoes — Bake them until the skins are dry and the centers are fully tender. Cool them before peeling so they hold their shape a little better when chopped.
- Bacon — Cook it until crisp, not chewy. A softer bacon topping goes limp in the hot soup, while crisp bacon keeps its bite.
- Chicken broth — This doesn’t make the soup taste chickeny; it keeps the dairy from tasting flat and gives the base a little savory depth. Vegetable broth works if needed, but the flavor will be slightly less rounded.
- Garlic powder — Just enough to echo the restaurant-style seasoning without overpowering the potato. Fresh garlic is stronger and can pull the soup away from the familiar baked-potato flavor.
Make the Roux First
Melt the butter over medium heat, then whisk in the flour and cook it for about 2 minutes. It should smell nutty and look like a smooth paste, not a dry clump. If the heat is too high, the roux will brown too fast and can give the soup a toasted flavor that doesn’t belong here.
Whisk in the Dairy Slowly
Add the milk, cream, and broth in a slow stream while whisking constantly. That gradual addition is what keeps the base smooth. If you dump it all in at once, the roux can seize into little lumps that take forever to dissolve. Keep the heat at medium and stir until the soup thickens enough to coat a spoon.
Finish With Potatoes, Cheese, and Sour Cream
Fold in the chopped baked potatoes, then mash a few pieces against the side of the pot to thicken the soup naturally. Stir in the cheddar until it melts completely, then add the sour cream and seasonings. Pull the pot off the heat if the cheese starts looking stringy or grainy; that’s your cue the burner is too hot.
How to Adapt This for Lighter, Louder, or Dairy-Free Bowls
Make It Gluten-Free
Swap the all-purpose flour for a cup-for-cup gluten-free flour blend and cook it in the butter the same way. The soup will still thicken well, though it may need an extra minute or two on the stove to reach full body.
Go Bacon-Lighter Without Losing the Flavor
Use four strips of bacon in the soup and save the rest for topping, or swap in turkey bacon for a leaner finish. You’ll lose a little of the smoky richness, so add an extra pinch of salt at the end to bring the flavor back into focus.
Dairy-Free Version
Use unsweetened oat milk or plain almond milk, plus a dairy-free butter and a creamy plant-based sour cream and cheddar alternative. The soup will be a little less rich and less tangy, but the baked potato texture still carries the dish.
Extra-Chunky Restaurant Style
Leave most of the potato pieces intact and mash only a small portion into the broth. You’ll get a soup with more bite and less of the mashed-potato feel, which is great if you want each spoonful to have visible potato chunks.
Storage and Reheating
- Refrigerator: Store for up to 4 days. It will thicken as it chills, so the texture gets a little tighter the next day.
- Freezer: It can be frozen, but the dairy may separate a bit when thawed. Freeze in portions and whisk well while reheating for the best result.
- Reheating: Reheat gently over low heat on the stove with a splash of milk or broth. Fast boiling is the mistake that makes the cheese turn grainy and the dairy split.
