Yes, using aluminum foil can indeed affect the cooking time and temperature of your recipe. Since aluminum foil is a good conductor of heat, it can cause food to cook faster than it would without foil.
This can potentially reduce the cooking time needed for your recipe. Moreover, because foil reflects heat, it might result in a higher effective cooking temperature. Therefore, when cooking with foil, it’s crucial to monitor your food closely to prevent overcooking.
Adjustments to cooking time or temperature might be necessary based on your oven and the particular dish you’re preparing.
