Recipe FAQs

Do I need to peel the zucchini first?

Peeling is up to you. The skin is thin so it is easy to consume, but some people find it hard to digest. You can go either way.

How else can I use frozen zucchini?

Frozen zucchini is perfect for soups and stews. You can add it to your pot frozen and it’ll thaw and heat perfectly. I just don’t recommend eating it in things like stir fry as it does lose its crunch as it thaws.
