Squash Leaves (Hobak-ip)
Cucurbita moschata
Hobakip — squash leaves — embodies the Korean principle of total-plant utilization. When Korean gardeners grow hobak in their home gardens, the vigorous vines produce enormous leaves far in excess of what the plant needs for photosynthesis. Rather than wasting this abundance, Korean cuisine turned the leaves into one of summer's most distinctive foods. The preparation requires a specific skill: peeling the fuzzy, slightly prickly skin from the underside of each leaf, a meditative task that Korean grandmothers have passed down through generations. Hobakip-ssam is a quintessential Korean summer home-cooking dish, rarely found in restaurants but beloved at family dinner tables.
New to Squash Leaves (Hobak-ip)?
Is this edible?
Yes! Many cuisines eat squash and pumpkin leaves — they're common in African, Southeast Asian, and Korean cooking.
What does it taste like?
Very mild — almost like a soft, edible napkin that subtly tastes of squash. The flavor is intentionally neutral because the leaf serves as a wrapper.
Where to buy
Korean grocery stores in summer, or grow your own. Some Korean groceries carry frozen pre-peeled hobakip. If you grow zucchini or butternut squash, those leaves work too.
How to prepare
The peeling step is critical: hold the stem, and use it to peel the fuzzy fibrous skin from the back of each leaf, pulling toward the edges. Steam the peeled leaves for 5-7 minutes until very soft. Serve with rice and ssamjang.
Pro tip: Peeling is the make-or-break skill for hobakip. If you skip peeling, the leaves will be unpleasantly scratchy on the tongue. Watch a Korean cooking video for the technique — it's much easier to learn by watching.
