Cooking every kind of pizza
Cooking frozen pizza
What is the best way to cook a frozen pizza — straight on the rack, on a tray, on a stone or steel, or in an air fryer?
Short answer
Start from the pack instructions; they are the product maker's tested baseline, and some frozen pizzas are not ready-to-eat (see the safety notes). Within those instructions, the base usually does better with more heat from below: a fully preheated oven and either the bare rack (for thin, firm pizzas the pack allows on the rack) or a preheated tray, stone or steel. A cold tray is the most common reason for a pale, soft base. A conductive surface such as a steel tends to shorten the bake, so check from the earliest time on the pack rather than the latest.
Why the base and the top cook at different speeds
A frozen pizza goes into the oven as a block of ice-bound dough, sauce and cheese. The top is heated by hot air and radiation from the oven walls and upper element; the base is heated by whatever it sits on. Those two routes deliver heat at very different rates, which is why the common complaint is a browned or even scorched top over a pale, soft or still-cold middle — or, on a very hot surface, a dark base under cheese that has barely melted.
Before anything can brown, the ice has to melt and a good share of the water has to evaporate. Evaporation takes a lot of energy and holds the surface it is leaving close to the boiling point of water, so browning cannot start until that surface has dried. The underside of the base is trapped against whatever it rests on, so its moisture escapes more slowly than the open top's; that is the mechanism behind a soft base on an otherwise well-coloured pizza. PizzaHQ's explainers on heat transfer and on moisture and evaporation go into this in more detail.
Many frozen pizza crusts are already partly or fully baked, so the job is less about setting raw dough than about heating through, driving off moisture and browning. That is why the target is a balance: enough heat from below to dry and crisp the base in roughly the time the top needs to melt and colour.
Why a cold tray softens the base
A baking tray that goes in cold has to warm up alongside the frozen pizza, so for the first part of the bake it is absorbing heat rather than delivering it. Meanwhile it seals the underside, so steam from the thawing base has nowhere to go. The result is often a base that is heated through but pale and bready rather than crisp.
Preheating the tray with the oven changes this: the base meets a hot surface straight away and starts drying sooner. The bare oven rack does the opposite of sealing — it lets hot air reach the underside and steam escape — which is why many packs suggest it for thin, firm pizzas. Thin trays heat quickly; heavy, dark trays and stones take much longer to come up to temperature, and America's Test Kitchen notes that an under-preheated stone produces a pale base.
A stone or steel stores heat and delivers it fast, steel faster than stone. Baking Steel, which sells steels, advises a long preheat, setting the oven a little below the pack temperature, and checking well before the pack time, because a conductive surface shortens the bake and a thin crust can go from browned to burnt quickly. Treat that as a reason to check early, not as evidence that a steel is necessary.
Thickness and airflow change the method
Thin, firm frozen pizzas have little mass to heat through, so the risk is the base and edges over-browning before the cheese is done; the rack or a preheated tray usually suits them, and a very hot steel can overdo them. Thick, rising-crust or pan-style frozen pizzas have a large cold mass in the middle, so the risk is the reverse: a browned top over an underheated centre. They usually need the full pack time and a moderate, steady heat from below rather than a very hot surface, and are often sold on their own tray for that reason.
Airflow matters too. A fan oven moves hot air across the top, which speeds melting and browning of the cheese but can also dry the edges; packs often give a lower temperature for fan ovens, because moving air transfers heat to the food faster than still air at the same setting. A crowded oven — two pizzas on two shelves, or one pizza over a tray of something else — blocks the air and radiant heat, and the lower pizza usually cooks slower underneath. PizzaHQ's oven settings and shelf position explainer covers what each setting does.
Air fryers and grills, honestly
An air fryer is a small fan oven with a heating element close to the food. It can crisp a small, thin frozen pizza quickly, but the strong top heat means the cheese and edges can colour before the centre and base are done, and only pizzas that fit flat in the basket without touching the element work at all. Whether it is safe to use depends on the product: use an air fryer only if the pack names it as a method (see the safety notes), and follow the appliance maker's guidance on preheating and liners.
A grill or barbecue with a lid can cook a frozen pizza, but most packs do not give grill instructions, the heat from below is usually much fiercer than from above, and the risk of a charred base under unmelted cheese is high. A stone or steel on the grill, indirect heat and a closed lid all reduce that imbalance. If the pack gives no grill method, it is an experiment, and the safety notes still apply. PizzaHQ's BBQ guides cover grill heat in general.
To thaw or not to thaw
Most packs say to cook from frozen, and the timings on the pack assume a frozen start. Opinion outside the pack genuinely differs. A pizza chef quoted by MEL Magazine argues that a pizza thawed properly can bake better on a hot surface; a food scientist in the same piece counters that pack instructions reflect the maker's testing and that melting ice crystals tend to soften texture. PizzaHQ does not settle this, and has not tested it.
What is clear is that a thawed pizza cooks faster than the pack time assumes, so a frozen-start time will overcook it, and thawing changes the food-safety picture — see the safety notes before deciding to thaw a product whose pack says to cook from frozen.
How the methods compare
| Method | Heat from below | Moisture escape | Main risk | Suits | Verdict |
|---|---|---|---|---|---|
| Bare oven rack | Moderate, from hot air and the element below | Good: the underside is open | Thin pizzas sagging between bars, or dripping toppings | Thin, firm pizzas whose pack allows the rack | Often the pack's own suggestion for thin pizzas, and a sensible default when it is. |
| Cold baking tray | Low at first: the tray is warming too | Poor: the tray seals the base | Pale, soft base | Floppy or heavily topped pizzas that need support | Convenient but the most common cause of a soft base; preheat the tray if the pack allows. |
| Preheated baking tray | Good from the start | Fair: still sealed, but drying starts sooner | Very thin pizzas browning fast underneath | Most pizzas, especially larger or floppier ones | A good all-round choice that adds support without a cold start. |
| Preheated stone | Strong and steady, once fully preheated | Fair to good: porous surface | Pale base if under-preheated; long preheat | Thin and medium crusts | Works well if genuinely preheated; check from the earliest pack time. |
| Preheated steel | Very strong: conducts heat fastest | Fair: sealed, but the base dries quickly | Base or edges over-browning; shorter bake | Thin crusts, checked early | Fast and crisp, but the most likely to overshoot; check well before pack time. |
| Air fryer | Moderate; strong heat from above | Good: fan-driven air | Top colouring before the centre is done; undercooking | Small, thin pizzas, only where the pack names the method | Quick for a small pizza, but use only if the pack names it (see the safety notes). |
| Grill or barbecue with lid | Very strong and often uneven | Good | Charred base under unmelted cheese | Experiments; rarely covered by pack instructions | Possible with indirect heat and a stone, but outside most packs' instructions. |
Food safety
These points come only from official food-safety bodies. Where they differ, both are given; follow the authority where you live.
Some frozen products look cooked but are not ready-to-eat. USDA FSIS says labels such as 'Cook and Serve', 'Ready to Cook' and 'Oven Ready' mean the product must be cooked, that the package instructions should be followed, and that a food thermometer is the way to check it has been cooked safely. FSIS's review of a 2021 Salmonella outbreak linked to a not-ready-to-eat frozen chicken product found it was undercooked in microwaves and air fryers when no thermometer was used; the same caution applies to any not-ready-to-eat frozen food, so use only the appliances the package names. EFSA gives the same advice for frozen vegetables not labelled ready-to-eat: cook them thoroughly, following the instructions on the pack.

Checking it is cooked: USDA FSIS advises that colour and appearance are not reliable indicators of safety and that a food thermometer is the way to check. Its chart gives no figure for pizza as such; its safe minimum internal temperature for leftovers and casseroles, the nearest category, is 165 °F (74 °C). The UK FSA asks for food to be steaming hot all the way through, and gives 70 °C for 2 minutes in the middle of the food as the standard for food to be fully cooked. Follow the pack if it states a different check.

Thawing: if you thaw a frozen pizza at all, USDA FSIS and the UK FSA advise thawing in the fridge rather than on the worktop, and the FSA advises using defrosted food within 24 hours. Where the pack says 'cook from frozen', follow it.

Common misconceptions
- “The cooking time on the box is a fixed number to set a timer for.”
- It is the maker's tested range for a typical oven. Ovens run hotter or cooler than their dial, and a preheated stone or steel shortens the bake, so check from the earliest time given and judge by the base and the cheese, not the clock.
- “A soft middle means the oven was not hot enough.”
- Often it means the heat from below was too low relative to the top — a cold tray, a crowded oven or too high a shelf — rather than the oven as a whole being too cool. Turning the whole oven up can scorch the top before the base dries.
- “A frozen pizza that looks cooked only needs warming through.”
- Some frozen products look cooked but are not ready-to-eat. Check the label and follow the pack instructions; see the safety notes.
What this page cannot tell you
PizzaHQ has not tested any product or method on this page. Packaged pizzas differ widely in thickness, toppings and how far the crust has been cooked, and domestic ovens differ in how hot they really run, so the pack instructions remain the baseline and any adaptation here is a starting point to check, not a setting to trust. Food-safety advice differs between countries: follow your local food-safety authority. The method comparison describes mechanisms, not measured results, and the question of thawing is genuinely contested outside the pack instructions.
