Pizza troubleshooter
Choose what you saw — up to three things — and, if you know them, what you baked on, the style and the bake. PizzaHQ ranks the likely causes from its 57 documented symptoms, 137 recorded causes and 36 equipment-specific branches, and for each one says why it fits, how to tell it apart from its neighbours, what you can still rescue, and what to change next time.
Ranked causes
Most likely
High-fat cheese baked too long or at too high a sustained temperature
Generally acceptedBake environment · from Cheese releases excessive oil
Extended heat exposure breaks down cheese proteins further, releasing more of the fat they were holding.
- Why it fits
- Recorded cause of "Cheese releases excessive oil", ranked 1 of 2 by PizzaHQ's editors.
- How to tell it apart
- A cheese that usually behaves well oiled off this time, after a longer or hotter bake than usual.
- Rescue it now
- Blot excess oil with a paper towel after baking
- Next time
- Blend a high-oil-release cheese with a more stable one, and avoid overbaking

Cheese blend skewed toward high-oil-release varieties like cheddar without a stabilising cheese
Generally acceptedCheese · from Cheese releases excessive oil
Some cheeses are simply more prone to oiling off than others when used alone.
- Why it fits
- Recorded cause of "Cheese releases excessive oil", ranked 2 of 2 by PizzaHQ's editors.
- How to tell it apart
- The oiling happens every time with this cheese, such as cheddar used alone, even at a normal bake time.
- Rescue it now
- Blot excess oil with a paper towel after baking
- Next time
- Blend a high-oil-release cheese with a more stable one, and avoid overbaking

Also possible
The cheese has been held past the point where its protein network contracts and squeezes out fat. A long domestic-oven bake keeps cheese at temperature far longer than a 90-second high-heat bake does, so it passes that point routinely.

- Why it fits
- Applies only if you are using "Pizza in a domestic oven".
- How to tell it apart
- Oil has pooled on the surface after a bake of eight minutes or more, particularly with a generous cheese layer.
- Rescue it now
- Blot the surface with kitchen paper — the oil sits on top and comes off cleanly.
- Next time
- Pull the pizza as soon as the cheese browns rather than waiting for more colour, use slightly less cheese, and consider adding it partway through a very long bake.

How this works
Every cause shown is one PizzaHQ has already documented, either on a symptom page or as an equipment-specific branch. The troubleshooter does not invent causes; it ranks the documented ones against what you told it.
A cause starts from its recorded evidence confidence and its editorial rank within its symptom. An equipment-specific cause for the equipment you used rises sharply, and causes for equipment you are not using are set aside. A kind of cause (bake environment, fermentation, toppings…) that also explains another thing you saw rises again — one explanation for two observations is more likely than two separate faults.
If you name a style, its recorded equipment fit, bake temperature and bake time are compared with yours; a bake far outside the style's range, or equipment PizzaHQ records as a compromise for that style, raises the heat and equipment causes and says why.
Assumptions
- Causes are bucketed — most likely, also possible, less likely — rather than given a percentage; the underlying ranking is additive and every addition is listed under 'Why it fits'.
- 'How to tell it apart' is the observation PizzaHQ records as distinguishing that cause from the symptom's others.
- Bake temperature and time only count when a style is chosen, because they are judged against that style's recorded range.
Limitations
- Only documented symptoms can be diagnosed. If what you see is not listed, the closest symptom page is the better starting point.
- Equipment-specific branches exist where equipment genuinely changes the answer; most dough-stage problems have none, by design.
- A ranking is a starting point for checking, not a verdict — the distinguishing observations are there so you can confirm or rule out each cause yourself.
