Before you start
What this method is trying to achieve
Potatoes give soup plenty of natural body, but high-speed blending can release too much starch. This method blends only part of the cooked soup, then folds it back into the chunky portion before cream and toppings are added.
Success looks like
Know the target before you cook
The soup should be thick and creamy but still flow from the ladle, with tender potato pieces and no sticky, stretchy or paste-like texture.
Ingredients
What you need
Base
- 6 slices bacon, cut into small pieces
- 3 medium carrots, diced
- 3 stalks celery, diced
- 1 medium onion, diced
Potatoes
- 6 small russet potatoes, peeled and diced
Liquid
- 1.9 L low-sodium chicken or vegetable broth — About 8 cups.
Thickener
- 240 ml milk — About 1 cup.
- 3 tbsp all-purpose flour
Finish
- 120 ml heavy cream — About 1/2 cup.
- 100 g cheddar cheese, grated — For serving.
- 2 tbsp chives or parsley, chopped — For serving.
Method
Cook by the cues, not just the clock
Render bacon
Cook the bacon in a soup pot over medium heat until crisp. Remove the bacon and leave a thin coating of rendered fat in the pot.
Cook vegetables and potatoes
Add carrots, celery and onion and cook briefly, then stir in the diced potatoes. Add broth and bring to a gentle boil. Cook until the potatoes are just tender, about 10 to 15 minutes depending on size.
Add measured thickener
Whisk the milk and flour until smooth, pour it into the pot and simmer about 5 minutes so the flour thickens the liquid and loses its raw taste.
Blend only part
Remove roughly half the soup, cool it briefly as needed for safe blender use, and pulse only until smooth. Return the puree to the unblended soup.
Finish gently
Stir in the cream and warm through without aggressive boiling. Adjust salt and pepper, then serve with cheddar, bacon and herbs.
Critical checkpoints
Stop here and check
Before blending: potatoes tender but not disintegrating?
The cubes hold shape but pierce easily.Stop the simmer before they collapse into starch-heavy fragments.
During blending: smooth already?
The blended portion has just lost visible chunks.Stop the blender immediately instead of chasing an ultra-smooth puree.
Soup sticky or stretchy?
The texture becomes paste-like, gummy or elastic rather than creamy.Use CookClue's potato-soup-gluey diagnosis to check blending, starch, thickener and reduction.

After cooking
Storage, reheating & substitutions
Storage
Refrigerate covered after cooling. Stir gently when reheating rather than re-blending.
Reheating
Warm over low to medium-low heat, adding a small amount of broth or milk if it has thickened too much.
Substitutions
Vegetable broth can replace chicken broth. Bacon may be omitted and olive oil used for the vegetable base.

Food Network's potato soup cooks potatoes in broth, adds a measured milk-flour mixture, blends only about half the soup and finishes with cream, parsley, cheddar and bacon.

Food Network explicitly warns to puree potato soup only until smooth because overworking the potatoes produces a gummy result.
