Baking time covers the distance between the food’s starting temperature and the temperature it needs to reach. Food taken from the refrigerator at 4°C / 40°F starts farther from the finish line than food that has warmed on the counter, and that difference adds to the cooking time. The difference may be a few minutes for thin pieces but as much as half an hour for thick, dense ones. There is a food-safety limit to leaving food on the counter.
An oven heats food toward the oven temperature, and that heating starts from the temperature of the food. A refrigerator is around 4°C / 40°F, while a kitchen is around 20°C / 70°F; the difference adds directly to the distance the center of the food has to travel. For a thin borek or vegetables arranged in a single layer, this difference amounts to a few minutes. It is much more noticeable with a deep casserole dish, a whole bird, or cold cake batter, and the recipe’s stated time may not be enough. Extend the cooking time to make up the difference; do not raise the temperature.
With glass and ceramic dishes, the dish’s own temperature also matters; a cold dish warms along with the food. Check the instructions for that specific product to confirm oven suitability and conditions for transferring it from refrigerator to oven. Do not assume that warming a dish slightly or heating it along with the oven is safe for every glass dish.
Food safety sets the limit on how long food can sit out. Raw or cooked food is in a range where bacteria multiply rapidly between 5–60°C / 41–140°F, and should not remain in this range for more than a total of 2 hours; above 32°C / 90°F, the limit is 1 hour. So it is not a good idea to leave food on the counter for hours to “come to room temperature.” For thin pieces, 15–20 minutes is usually enough; for thick pieces, half an hour is usually enough, and both fit within the 2-hour limit. Put raw poultry and ground meat directly into the oven without leaving them on the counter.
Some foods are meant to start cold. Breaded and frozen products go into the oven without thawing; the coating falls apart if thawed. In laminated dough, keeping the butter cold helps the layers separate, so put the dough in the oven as soon as it comes out of the refrigerator. Cookie dough is also baked cold so it does not spread on the baking sheet. These recipes give cooking times for a cold start, and letting the dough warm up will spoil the result. The recipe will say when a cold start is intended.
Measuring is the most reliable way to estimate cooking time. For food that starts cold, check it at the end of the recipe’s stated cooking time, and leave it in the oven for a few more minutes if needed. For meat and poultry dishes, use a thermometer to decide; the thickest part of poultry should reach 74°C / 165°F. Raising the oven temperature does not make up for a cold start; it only causes the outside to brown too early, while the center continues to heat at its own pace.

Tarifteki sürelerin oda sıcaklığındaki malzemeye göre yazıldığını hiç düşünmemiştim. Dolaptan çıkardığım güveci doğrudan fırına veriyor ve süre dolunca ortası soğuk çıkınca fırını suçluyordum. Yarım saat tezgâhta beklettiğimden beri sorun kalmadı.
Cam kabın kendi sıcaklığının da hesaba katılması iyi bir ayrıntı, borcam bende gerçekten geç ısınıyor.
