You can freeze whole tomatoes directly in zip-top bags, and the freezing process actually makes peeling them easier when you’re ready to use them in soups, sauces, and stews, which is a key benefit of preserving your garden harvest through this method, allowing for easy use in various dishes with minimal preparation.

Freezing Whole Tomatoes

Why struggle with tomato freezing methods when whole tomatoes make it simple? Wash and dry your ripe tomatoes thoroughly, then toss them straight into freezer bags.

Peeling Frozen tomatoes becomes effortless—skins slip right off after thawing. While Texture Changes occur, Flavor Retention stays strong for six months.

Best Varieties include beefsteaks and heirlooms. Avoid Freezing Green tomatoes since they lack developed flavor.

Remove excess air from bags to prevent freezer burn and maintain quality.
