The only real “danger” with an oven bag is forgetting to cut a few small slits in the top. You read that right—the bag needs steam vents so it doesn’t puff up like a balloon. Just snip a few little holes with scissors, and you’re golden. Think of it like poking holes in a baked potato so it doesn’t explode.
And please, please don’t fill the bag to the brim. Leave a little space for hot air to circulate. A cozy turkey is great; a cramped turkey is just sad.
