Yes, you can freeze cherry tomatoes whole and you don't even need to blanch them! Wash and dry your cherry tomatoes, then transfer them to a sheet pan. Place the sheet pan into the freezer until the cherry tomatoes are frozen. Place the tomatoes into a freezer-safe bag and label with the date. Frozen tomatoes aren't ideal for salads or recipes that call for fresh tomatoes, instead use them in sauces, soups, and stews.
