Thick, creamy potato soup doesn’t need a long ingredient list to taste like something you’ve been simmering all afternoon. This version turns humble russet potatoes into a bowl that’s hearty, smooth, and studded with enough chunks to keep every spoonful interesting. The cream of chicken soup gives it body fast, and the sour cream finishes it with a gentle tang that keeps the whole pot from tasting flat.
What makes this one work is the order. The potatoes cook in broth first, which seasons them from the inside out and gives you a starchy cooking liquid that helps the soup thicken naturally when you mash some of the potatoes back in. The cream of chicken soup goes in after the potatoes are tender, so it blends in without catching on the bottom, and the sour cream gets stirred in off the heat or on very low heat so it stays smooth instead of turning grainy.
Below, I’ve included the texture cue that tells you when the potatoes are ready, the one substitution that keeps this soup working, and a few ways to stretch it into a fuller meal without losing the simplicity that makes it so good.
The potatoes got perfectly tender in about 20 minutes, and mashing half of them made the soup thick without turning it gluey. I added cheddar and bacon on top and my husband went back for a second bowl immediately.

The Fastest Way to Ruin This Soup Is Boiling It Too Hard
Potato soup looks forgiving, but the texture goes sideways fast if you rush the simmer. A hard boil breaks the potatoes apart before they cook evenly, which gives you a mix of chalky centers and gluey edges instead of a bowl that’s creamy with a few soft chunks. A steady simmer is what keeps the potatoes intact long enough to cook through while still letting the broth pick up body from the starch.
The other place people trip up is after the potatoes are tender. If you stir in the sour cream while the pot is still ripping hot, it can curdle or turn grainy. Low heat is enough here. You’re warming the soup through, not cooking it again.
What Each Ingredient Is Actually Doing in This Soup
- Russet potatoes — These are the backbone of the soup. Russets break down more readily than waxy potatoes, which helps thicken the broth without needing flour or cornstarch. If you swap them, use another starchy potato, not a firm salad potato, or the soup will stay thin.
- Cream of chicken soup — This is doing the heavy lifting for both flavor and body. It gives you built-in seasoning and a creamy base in one can. If you need a different option, cream of celery works, but the soup will taste lighter and a little less savory.
- Chicken broth — Broth cooks the potatoes and seasons them at the same time. Use a broth you’d actually drink, because bland broth makes bland soup. If your broth is very salty, hold back on extra salt until the end.
- Sour cream — This is what makes the soup taste finished instead of just thick. It adds tang and a smoother, richer texture. Full-fat sour cream is best here because lower-fat versions are more likely to split when heated.
Building the Soup So It Stays Creamy, Not Gluey
Cooking the Potatoes in Broth
Put the cubed potatoes and broth in a large pot and bring it to a boil, then lower the heat to a steady simmer. You want the potatoes tender enough to break apart easily with a fork, but not so overcooked that they disintegrate before you mash them. If the pot is boiling hard, the outside of the potatoes will collapse before the centers are done.
Mashing for Texture
Once the potatoes are tender, mash most of them right in the pot. Leave some chunks behind so the soup still feels hearty and homemade. An immersion blender is not the move here unless you want a much smoother, heavier soup, because blending all the potatoes can turn the texture past creamy and into paste-like.
Finishing With the Dairy
Stir in the cream of chicken soup until it disappears into the broth and potatoes, then lower the heat before adding the sour cream. Stir until the soup looks smooth and even, with no streaks of white. If you add the sour cream to a very hot pot, it can separate, so keep the heat gentle and stop as soon as the soup is hot through.
How to Adapt This for a Bigger Pot, a Lighter Bowl, or a Dairy-Free Swap
Make it dairy-free
Use a dairy-free sour cream and a dairy-free condensed cream soup if you can find one. The result will be a little less rich and a little more savory, but the potatoes still give the soup enough body to feel substantial.
Use cream of celery instead of cream of chicken
This swap keeps the same creamy texture and makes the soup a little lighter in flavor. It works especially well if you’re serving it with bacon or cheddar on top, since those toppings bring back some of the savory depth.
Add extra vegetables without losing the texture
A handful of finely diced celery or a cup of frozen corn can go in with the potatoes. Keep the pieces small so they blend into the soup instead of fighting the soft potato texture.
Storage and Reheating
- Refrigerator: Store in an airtight container for up to 4 days. It will thicken as it sits, especially once the potatoes cool.
- Freezer: It freezes, but the texture changes a bit because of the sour cream. Freeze in portions if you want, then thaw overnight in the fridge before reheating.
- Reheating: Warm it slowly on the stove over low heat, stirring often. If it looks too thick, add a splash of broth to loosen it. High heat can make the dairy separate and can scorch the bottom of the pot.

Method
- Place cubed potatoes and chicken broth in a large Dutch oven, then bring to a boil. Once boiling, keep the bubbles active for the start of the simmer, using the potatoes as your visual cue for doneness timing.
- Reduce heat to a simmer and cook for 18-20 minutes, until the potatoes are very tender. You should be able to press a chunk easily with a spoon and have it break apart.
- Mash most of the potatoes directly in the pot, leaving some chunks for texture. Stop mashing when the soup looks partially thickened with visible potato pieces.
- Stir in the cream of chicken soup until fully incorporated. Mix until no streaks remain and the soup looks uniformly creamy.
- Reduce heat to low, then stir in the sour cream until smooth and heated through. Keep it at low heat—watch for a silky texture without bubbling strongly.
- Season with salt and pepper if needed. Taste and adjust until the flavor pops without overpowering the potato sweetness.
- Ladle the soup into bowls. Top each serving with shredded cheddar, green onions, and bacon bits if desired.
