Can you freeze zucchini and summer squash?


We are overwhelmed with zucchini and summer squash! Can I freeze either or both for winter use in soups, etc? If so, how do I prepare them — just cut up or dice and put in freezer bags, or otherwise?

You can definitely freeze zucchini and summer squash! (Or sneak it onto your neighbor’s porch under the cover of night). You can freeze them sliced or grated (grated squash is a great addition to frittatas!). From our Bulletin #4384: Freezing Vegetables

See the bulletin for complete instructions on blanching and selecting containers. Happy harvesting!
