Frequently Asked Questions

Can you eat acorn squash skin?

Yes! When cooked, acorn squash skin becomes tender and edible, unlike butternut squash. It adds fiber and saves prep time. The ridged shape makes peeling difficult anyway.

How do you know when acorn squash is ripe?

Look for dull, not shiny, skin (shiny indicates under-ripe), deep green color with orange patches, a heavy feel for its size, and hard, woody stem. The skin should resist puncture with a fingernail.
