Good Housekeeping reports that storing sheet pans and other items in an oven can interfere with heat circulation and may affect cooking performance. Items left inside can also be damaged or create a fire risk if they are not oven-safe; the report recommends checking that the oven is empty before use.
Good Housekeeping has reported that storing sheet pans and other items inside an oven can obstruct heat circulation, potentially affect cooking results and add strain to the appliance. The warning, attributed to AO.com appliance expert Jade Golding-Gault, centers on a common kitchen habit: leaving cookware in the oven and forgetting it is there when the oven is turned on.
Golding-Gault said trays or pans inside an operating oven can restrict airflow and prevent heat from circulating efficiently. The effect depends on the item’s size and position and the oven setting. In a fan-assisted oven, a large pan on the floor may block circulating air; in a conventional oven, a tray on the lowest shelf can absorb heat from below. The report says this may contribute to uneven cooking and make the oven work harder.
The report also warns of possible longer cooking times and higher energy use, but its cost example is an estimate rather than a measurement of the effect of storing pans. It cites Go Compare’s figure of 53 pence per hour for using a 2,000-watt electric oven, or £192.36 per year, then estimates that an additional 10 minutes of oven use per hour would add about £30 annually. The source does not provide a study showing that stored cookware causes that extra operating time.
Repeatedly heating items unintentionally may also cause wear to cookware, especially items not designed for prolonged high temperatures, Golding-Gault said. The report warns that forgotten items such as cookware with plastic or rubber handles, food packaging or other household objects may melt or become damaged, and in some cases could pose a fire risk. Golding-Gault said regular oven loading may also put additional demand on heating elements and fan systems.
How Stored Pans Can Affect Cooking
For households using the oven regularly, keeping it clear can reduce the chance that an item interferes with airflow or is exposed to heat by mistake. Those issues could affect cooking and, according to the expert cited, place added demand on oven components. The supplied report does not quantify how often such problems occur or establish a typical increase in energy bills or repair costs, so the possible financial effects should not be read as guaranteed outcomes.
The most immediate practical concern is forgetting what is inside before switching the oven on. A pan may be suitable for baking but still have handles or coatings that are not intended for the oven’s operating conditions. Packaging and other household items may be less suitable still. Clearing the cavity before use is a simple way to avoid heating an item unintentionally.
The Case for a Clear Oven
The Good Housekeeping report addresses a storage workaround for kitchens short on cupboard or drawer space. An oven can look like an unused compartment when it is off, and cookware may appear suited to heat. The report’s central distinction is between having an item in a cold oven and leaving it there when the appliance is used: the stated concerns arise during operation or when an item is forgotten.
Some people put a spare tray on the oven floor to catch drips and spills. Golding-Gault advises against using a tray there, and the article instead suggests a reusable oven liner designed for that purpose. It says to check compatibility with the oven, follow the manufacturer’s replacement guidance, and replace a liner if it warps or becomes damaged. The source estimates liners often last around six months, while directing readers to confirm timing with the brand.

How Much Extra Energy Use
The report does not quantify the typical effect of stored pans on cooking time, energy consumption, breakdowns or repair costs. Its £30 annual cost example assumes an extra 10 minutes of oven use per hour; the supplied material does not establish that cookware storage causes that specific delay. It is also unclear how much the impact varies among oven designs, settings and cookware placements.
The report does not identify a particular test or data set behind its performance and wear warnings. Readers should treat them as risks described by the cited appliance expert, rather than as outcomes that will occur every time a pan is left in an oven. The precise compatibility and replacement schedule for oven liners also depend on the oven and liner manufacturer’s instructions.
Check Before Turning It On
Before using the oven, remove stored trays, pans and other items, then check the cavity for anything that could melt, become damaged or obstruct airflow. For spill protection, consult the oven manual and the liner manufacturer’s instructions to confirm that a reusable liner is compatible and where it can be placed. Replace a liner if it is warped or damaged, and follow its stated care and replacement guidance.
Key Questions
Can sheet pans stay in the oven while it is off?
The report focuses on risks when the oven is operating or when stored items are forgotten. It recommends keeping the oven clear before use; it does not claim that a cold oven will damage every pan.
Why can a pan affect cooking?
According to AO.com expert Jade Golding-Gault, a pan can restrict airflow or absorb heat, depending on its position and the oven setting. That may affect heat distribution and cooking results.
Can a stored pan create a fire risk?
The report says forgotten items that are not oven-safe, including cookware with plastic or rubber handles and food packaging, may melt or become damaged and could in some cases create a fire risk.
What can go on the oven floor to catch spills?
The article suggests a reusable oven liner rather than a tray, provided it is compatible with the oven. Check the oven and liner instructions, and replace the liner if it warps or becomes damaged.
