• Here’s the very easiest way to freeze your tomatoes, no peeling or simmering required! Place tomatoes on a baking sheet lined with parchment in a single layer and place in the freezer until solid, 3 to 4 hours.

•  Bag and seal tightly. Transfer the frozen tomatoes to resealable plastic bags, remove excess air, and stash them in the freezer. 

That’s it! Thaw the tomatoes for a few hours in the fridge; the peels will slip off easily, and you can use your fingers to remove the seeds too if you like. In a rush? Run frozen whole tomatoes under warm water to release the skins without having to thaw them first.
