bake according to the chart on your turkey.
i have been using oven bags for several years and i have never made a bad turkey ( i give all the credit to the bag- big birds still scare me!).
another quick tip- if you have 20 pounds of potatoes to wash for your thanksgiving meal throw them in the top shelf of the dishwasher. set on the quick rinse cycle and let your dishwasher clean the potatoes. not something i would do every day, but definitely a space and time saver during the holidays.
i can’t even begin to know how to cook a turkey without a bag!! that’s all i ever learned
