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
Bottom heat dominant relative to top heat, common with a very hot steel and weak top element
Generally acceptedBake environment · from Base cooks before the toppings finish
A steel's high thermal mass can finish the base well before a moderate top element browns the toppings and melts the cheese fully.
- Why it fits
- Recorded cause of "Base cooks before the toppings finish", ranked 1 of 2 by PizzaHQ's editors.
- How to tell it apart
- Even a light topping lags behind a finished base, usually on a very hot steel under a weak top element.
- Rescue it now
- Finish briefly under a broiler, or move to a higher rack for the remainder of the bake
- Next time
- Balance top and bottom heat sources, and pre-cook slow-cooking toppings before assembly

Toppings too thick or dense to finish in the base's cook time
Generally acceptedToppings · from Base cooks before the toppings finish
Some toppings genuinely need more time or heat than the base does.
- Why it fits
- Recorded cause of "Base cooks before the toppings finish", ranked 2 of 2 by PizzaHQ's editors.
- How to tell it apart
- Thinly topped areas finish with the base, and only the thick, dense or piled toppings stay underdone.
- Rescue it now
- Finish briefly under a broiler, or move to a higher rack for the remainder of the bake
- Next time
- Balance top and bottom heat sources, and pre-cook slow-cooking toppings before assembly

Also possible
This is the steel's characteristic imbalance rather than a fault. Fitting a steel solves bottom heat so effectively that top heat becomes the limiting factor, and nothing about the steel addresses the top of the pizza.

- Why it fits
- Applies only if you are using "Cooking on a pizza steel".
- How to tell it apart
- The base is properly done and the cheese has melted but not browned, on a steel in a domestic oven.
- Rescue it now
- Finish under the grill for 60–120 seconds.
- Next time
- Position the steel about 15–18 cm below the grill element and treat the grill finish as part of the method rather than a rescue. Check whether your oven disables the grill above a certain set temperature.

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.
