Gnocchi has an unusually useful opposite-failure pattern. Dough that is too wet can disintegrate in the pot, while dough with too much flour or too much kneading survives easily but becomes heavy. Adding more flour is the right correction for one batch and exactly the wrong correction for the other.
Symptom matcher
Which one looks most like yours?
Small visual differences can point to very different causes.
Test the raw dough for stickiness and moisture.
Check potato variety and how the potatoes were cooked.
Lower the water to a gentle simmer and test one.
Recheck total flour added.
Review how long the dough was kneaded.

Can it be saved?
Yes, if you catch the problem with a test piece before cooking the whole batch.
Limit: Adding too much corrective flour can turn the opposite problem into dense gnocchi, and already-cooked dense gnocchi cannot be made lighter.

Get to the first clue faster
Answer one question at a time. The result comes from the same reviewed diagnosis data below.
Do the gnocchi break apart or dissolve in the cooking water?
Does the raw dough feel very sticky or wet?
Adjust the dough moisture
Sticky dough that disintegrates needs more structure or drier potato.
Likely cause: The potato dough was too wet for the amount of binderCheck the cooking water
If the dough feels workable, violent boiling may be tearing the dumplings apart.
Likely cause: The gnocchi were cooked in a hard rolling boilDo they hold shape but eat dense, dry or chewy?
Check flour amount
Dense but intact gnocchi point first to excess flour.
Likely cause: Too much flour made the gnocchi denseCheck handling and potato moisture
If flour was controlled, review kneading and the moisture of the potato base.
Likely cause: The dough was kneaded or handled too muchDiagnosis
Check the likely causes
Start at the top, but skip anything that clearly does not match your batch. Evidence labels describe the support for each cause, not a fake probability score.
The potato dough was too wet for the amount of binder
The raw dough is very tacky and soft, and a test gnocchi clouds the water or begins to dissolve.
Poach one test piece before shaping the whole batch. If it breaks apart, work a small amount of flour into the remaining dough and test again.
Stop cooking the rest. Adjust the uncooked dough with a small amount of flour and retest one piece.
Use drier potatoes and add flour gradually only until the dough just holds together.
The potatoes brought too much water into the dough
The riced potato feels wet or pasty before flour is added and the dough stays sticky despite repeated dusting.
Check potato type and preparation. Russets are higher-solids and lower-moisture than waxier potatoes, and baking or thoroughly drying potatoes reduces the water load.
If the dough is still uncooked, add only enough flour to pass a test poach.
Choose a high-solids potato and use a preparation that keeps the potato flesh dry.
The gnocchi were cooked in a hard rolling boil
Pieces hold together before cooking but physically break or batter against one another in violently moving water.
Cook one piece at a bare simmer or gentle poach. If it survives while the rolling-boil batch breaks, water movement was important.
Lower the heat to a gentle simmer before cooking the remaining gnocchi.
Poach or simmer gnocchi gently and avoid overcrowding.
Too much flour made the gnocchi dense
The gnocchi survive the pot perfectly but feel dense, dry or bready when bitten.
Compare the flour amount with a tested recipe and notice whether extra flour was repeatedly added to stop sticking.
There is no reliable way to lighten cooked gnocchi made with excess flour.
Add flour incrementally and stop as soon as the dough is cohesive enough to handle and test-poach.
The dough was kneaded or handled too much
The dough becomes smooth, elastic and firm rather than just cohesive and tender.
Think about handling time. If the dough was kneaded like bread after it had already come together, overworking is a strong suspect.
Cooked heavy gnocchi cannot be made pillowy again.
Mix and fold gently only until the ingredients form a workable dough.
Don't jump to conclusions
Common misdiagnoses
Kitchen science
What is actually happening?
Potato gnocchi needs just enough flour and egg, where used, to bind the potato into a dough. Potato moisture changes how much flour the dough needs. High-moisture potatoes demand more binder, while too much flour or prolonged kneading develops a firmer, denser structure.
Testing plan
What we plan to test
Planned tests are shown transparently and are never presented as completed results.
Gnocchi structure: potato moisture, flour and water movement
Wet dough will fail by disintegration, while excess flour or handling will fail by density; hard boiling will create a separate mechanical breakage pattern.

Recommends Russet Burbank because of high solids and low moisture and explains why waxier potatoes are more prone to gluey texture.
