Does parchment paper make baking time longer?

No, parchment paper generally does not make baking time longer. In fact, it can sometimes slightly shorten baking time. Here's why:

* Even Heat Distribution: Parchment paper helps distribute heat evenly across the baking sheet, leading to more consistent and faster cooking.

* Reduced Stickiness: Parchment paper prevents food from sticking to the baking sheet, eliminating the need to grease it. This reduces the amount of time it takes for the food to reach the desired temperature.

* Air Circulation: Parchment paper allows for better air circulation around the food, promoting more even browning and faster cooking.

However, there are a few factors that could make baking time longer:

* Thickness of Parchment Paper: Thicker parchment paper can slightly insulate the food, potentially slowing down the cooking process.

* Type of Food: Some foods, like cookies or brownies, might require slightly longer baking times with parchment paper, due to its insulating properties.

Overall, parchment paper is a beneficial baking tool that can often lead to faster and more consistent results. If you're unsure about the baking time for a specific recipe, it's always best to check the recipe instructions or use a food thermometer to ensure proper doneness.
