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

  1. Excess moisture from sauce or toppings

    Generally accepted

    Toppings · from Base is soggy

    High-water-content toppings (mushrooms, fresh tomato, under-drained pineapple) release liquid onto the base during baking.

    Why it fits
    • Recorded cause of "Base is soggy", ranked 1 of 4 by PizzaHQ's editors.
    How to tell it apart
    The sogginess sits under the wettest toppings or heaviest sauce, often with visible liquid pooled on top.
    Rescue it now
    Finish briefly on a very hot surface or under a broiler if the top is already done but the base isn't set
    Next time
    Pre-cook high-moisture toppings, preheat the baking surface thoroughly, and don't over-sauce

  2. Baking surface not preheated enough to set the base quickly

    Generally accepted

    Bake environment · from Base is soggy

    A cooler surface takes longer to set the base, giving moisture more time to soak in before the crust firms up.

    Why it fits
    • Recorded cause of "Base is soggy", ranked 2 of 4 by PizzaHQ's editors.
    How to tell it apart
    The base is soggy all over, edges included, and the stone, steel or tray went in with the pizza or had only a short preheat.
    Rescue it now
    Finish briefly on a very hot surface or under a broiler if the top is already done but the base isn't set
    Next time

Also possible

  1. Bake time too short or temperature too low for the moisture load

    Generally accepted

    Bake environment · from Base is soggy

    A quick, hot bake evaporates surface moisture faster than a slow, cool one.

    Why it fits
    • Recorded cause of "Base is soggy", ranked 3 of 4 by PizzaHQ's editors.
    How to tell it apart
    The whole pizza looks pale and underdone, top and bottom, rather than wet only in particular spots.
    Rescue it now
    Finish briefly on a very hot surface or under a broiler if the top is already done but the base isn't set

  2. A thin peel, screen, or pan with low thermal mass, specifically when the sogginess is concentrated in the middle rather than the whole base

    Generally accepted

    Equipment · from Base is soggy

    A thin baking surface has little stored heat to give up as the pizza's centre — the last part of the base to firm up — needs it; the edges often set fine from residual ambient oven heat while the middle stays underdone and absorbs moisture. A stone or steel with real thermal mass fixes this specifically, where simply baking longer often just overcooks the edges instead.

    Why it fits
    • Recorded cause of "Base is soggy", ranked 4 of 4 by PizzaHQ's editors.
    How to tell it apart
    The edges are crisp but the middle is wet, on a thin tray, screen or pan, and baking longer only darkens the edges.
    Rescue it now
    Finish briefly on a very hot surface or under a broiler if the top is already done but the base isn't set

  3. Not enough bottom heat to evaporate topping water as fast as it arrives. In a domestic oven baking on a bare shelf or an unheated tray, the base is the coolest part of the pizza throughout the bake.

    Why it fits
    • Applies only if you are using "Pizza in a domestic oven".
    How to tell it apart
    The base is wet specifically in the middle, under the sauce, while the rim is dry and cooked.
    Rescue it now
    Move the pizza directly onto a preheated surface for the last two minutes, or onto the oven's lowest shelf.
    Next time
    Fit a stone or steel and preheat it fully, and reduce the water going on in the first place — strained sauce, drier cheese, pre-cooked vegetables.

  4. The tray was floured or used dry rather than generously oiled. On a low-mass tray, oil is the mechanism that conducts heat into the base — without it there is nothing to crisp against.

    Generally accepted

    Why it fits
    • Applies only if you are using "Pizza on a baking tray".
    How to tell it apart
    A tray-baked pizza is soft and pale underneath with no crisping at all.
    Rescue it now
    Little can be done mid-bake; move it as low in the oven as possible.
    Next time
    Oil the tray properly — more than feels right — and use the heaviest, darkest tray you own. Consider preheating a second tray beneath it.

Less likely

  1. A solid liner or tray under the pizza catches the water and fat the pizza releases and holds them against the base, where an open basket would let them drain and the air dry the underside.

    Why it fits
    • Applies only if you are using "Pizza in an air fryer".
    How to tell it apart
    The base is wet rather than merely pale, with moisture or fat pooled on a liner or in a solid-bottomed tray under the pizza.
    Rescue it now
    Lift the pizza off the liner onto the bare basket or rack for the last few minutes so the underside can dry.
    Next time
    Cook on the perforated basket or rack, using only a liner the appliance maker allows and one with holes, and pre-cook or drain any wet toppings you add.

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.
