Korean Squid (Ojingeo)

TL;DR: Ojingeo (오징어) — Korean squid — is a versatile cephalopod central to Korea’s coastal cooking, especially along the East Sea. It appears fresh in fiery stir-fries and clean raw platters, and dried as Korea’s classic drinking snack. Low in fat yet rich in protein and taurine, squid delivers a springy texture and savory umami depth that Korean home cooks build entire meals around.

Ojingeo (오징어) is the Korean word for squid, a lean, high-protein seafood harvested mainly from Korea’s East Sea. Prized for its springy texture and clean, briny-sweet flavor, it appears in dishes ranging from spicy ojingeo-bokkeum to chewy dried snacks, and is one of the richest dietary sources of taurine.

What Is Ojingeo (Korean Squid)?

Ojingeo (오징어) is the Korean name for squid, a ten-armed cephalopod mollusk. The species most Koreans eat is Todarodes pacificus, the Japanese flying squid, hauled in by the boatload from the East Sea off Gangwon Province, Sokcho, and the island of Ulleungdo. It is distinct from two relatives that share Korean tables: gapojingeo (갑오징어) — cuttlefish, with its broad internal bone — and nakji (낙지) or muneo (문어), the smaller and larger octopuses.

Squid has been a coastal staple for centuries. Because fresh squid spoils quickly, fishing communities long ago learned to air-dry the catch on seaside racks, turning a perishable animal into a shelf-stable trade item. That tradition still shapes how Koreans buy and eat squid, which is why dried squid is as familiar here as fresh. Ojingeo is, in short, a lean cephalopod that has anchored Korea’s East Sea fishing economy for generations.

What Does Ojingeo Taste Like?

Fresh ojingeo has a mild, clean, faintly sweet flavor with a gentle brine — far less "fishy" than oily fish, with a savory umami undertone that comes from its naturally high free-amino-acid content. The defining quality, though, is texture: Koreans prize the jjolgit (쫄깃) springy chewiness that good squid delivers.

That texture is also unforgiving. Squid is tender when cooked either very briefly (a minute or two over high heat) or low and slow (a long braise), but turns rubbery in the awkward middle. Scoring the flesh in a crosshatch pattern before cooking helps it stay tender and lets sauce cling. A splash of rice wine and a little ginger tames any residual brine without masking the sweetness. Dried squid is a different experience entirely: drying concentrates the amino acids into an intense, lingering umami, and the chew becomes deliberate and satisfying — exactly what makes it such an addictive snack.

How Is Ojingeo Used in Korean Cooking?

Ojingeo is one of the most adaptable ingredients in the Korean kitchen, but three preparations show off its range best.

1. Ojingeo-bokkeum (오징어볶음) — spicy stir-fried squid. This is the dish most foreigners meet first: squid stir-fried over high heat with onion, scallion, and a glossy red sauce built on gochujang and gochugaru (Korean red pepper powder). It is sweet, spicy, and savory all at once, and it is a regional point of pride along the East Sea — the spicy stir-fried squid served at coastal restaurants like this Gangwon specialist in Goseong leans on impeccably fresh local catch. The gochujang at the heart of the sauce carries its own deep history of Korean jang fermentation.

2. Mareun ojingeo (마른오징어) — dried squid as anju. Dried squid is Korea’s quintessential anju (안주) — food eaten while drinking — torn into strips and chewed alongside beer or soju, often grilled briefly and dipped in mayonnaise-gochujang sauce. Shredded dried squid is also stir-fried into a sweet-spicy banchan called ojingeo-chae-bokkeum (오징어채볶음). A popular halfway form is pidegi (피데기) — semi-dried squid that keeps a little moisture for a softer bite.

3. Ojingeo-sundae (오징어순대) — stuffed squid. This Gangwon specialty stuffs whole squid tubes with a savory mix of glass noodles, pork, and vegetables, then steams and slices them into pinwheels. The dangmyeon filling is the same springy sweet-potato glass noodle used in japchae. Squid also adds chew and brine to haemul pajeon, the Korean seafood scallion pancake, and on Ulleungdo it is sliced fresh as hoe (회) — raw seafood — served with a ssamjang-style dipping paste.

How Do You Store Ojingeo?

Fresh squid is highly perishable and should be cooked within one to two days of purchase, kept on the coldest shelf of the refrigerator over ice if possible. To store longer, clean it first — remove the head, innards, beak, and cartilage "pen," peel the skin if desired, then rinse and pat dry — and freeze in an airtight bag for up to about three months. Squid freezes well; thaw it overnight in the refrigerator rather than at room temperature to keep the texture firm.

Dried squid is far more forgiving. Fully dried mareun ojingeo keeps for several months in a cool, dry, dark place, and for even longer in the freezer, where it also stays pleasantly chewy. Semi-dried pidegi retains moisture, so refrigerate or freeze it and use it within a few weeks. If dried squid develops a faint white surface bloom, that is usually harmless crystallized taurine and amino acids — a sign of good drying, not spoilage.

What Can I Substitute for Ojingeo?

The closest substitute for fresh ojingeo is cuttlefish (gapojingeo), which is slightly more tender and a touch sweeter and behaves the same way in stir-fries and braises. Octopus (nakji or muneo) works in spicy stir-fries too, though it needs longer cooking and brings a meatier chew. Outside Korean markets, calamari is simply the Mediterranean name for the same animal, so any fresh or frozen calamari tube or ring can stand in directly.

For texture rather than species, shrimp or scallops can replace squid in seafood pancakes and soups, though they lose the signature springiness. When a recipe calls for dried shredded squid and you cannot find it, dried shredded cuttlefish is the standard swap and is often used interchangeably in Korean home kitchens. Match the cut and the cooking time, and most squid dishes adapt gracefully.

Nutritional Profile & Health Benefits

Squid is a standout lean protein: about 16 grams of protein per 100 grams raw, with very little fat, according to USDA FoodData Central. It is rich in selenium, vitamin B12, copper, and — notably — taurine, a sulfur-containing amino acid that supports bile production and is concentrated in muscle and skin tissue. Ojingeo is, in fact, one of the richest dietary sources of taurine available.

The honest caveat is cholesterol: squid carries roughly 230 milligrams per 100 grams, which is high relative to most seafood. For most people, current evidence suggests dietary cholesterol has only a modest effect on blood cholesterol, and overall eating pattern matters far more, as Harvard Health explains — but those advised to limit cholesterol should be mindful of portions. Dried squid is also salty, so it is best enjoyed in moderation, and as a mollusk it is a shellfish allergen.

Frequently Asked Questions

What does ojingeo taste like? Fresh ojingeo tastes mild, clean, and slightly sweet with a light brine and savory umami depth — much less fishy than oily fish. Its hallmark is a springy, chewy texture Koreans call jjolgit. Dried squid is more intense, with concentrated umami and a deliberate, satisfying chew.

How do you store ojingeo? Cook fresh squid within one to two days, kept very cold. To store longer, clean it and freeze in an airtight bag for up to three months, thawing overnight in the fridge. Fully dried squid keeps for months in a cool, dry place and even longer frozen.

What can I substitute for ojingeo? Cuttlefish is the closest match in both flavor and texture, and calamari is the same animal under a different name. Octopus works in spicy stir-fries with longer cooking. For dried shredded squid, dried shredded cuttlefish is the usual swap in Korean home cooking.

Is squid high in cholesterol? Yes — squid contains around 230 milligrams of cholesterol per 100 grams, higher than most seafood. However, for most people dietary cholesterol modestly affects blood levels, and overall diet matters more. Those managing cholesterol should simply watch portion size and pair squid with vegetables and whole grains.

How are squid, cuttlefish, and octopus different in Korean cooking? Ojingeo (squid) is the most common, with long tubes and a springy chew. Gapojingeo (cuttlefish) is broader, softer, and sweeter. Nakji and muneo (octopuses) are meatier, need longer cooking, and star in their own spicy dishes. All three are popular but not perfectly interchangeable.

🩺 Dr.’s Nutritional Insight

Squid is among the richest dietary sources of taurine, a sulfur-containing amino acid that does more than aid digestion. In cultured human skin models, taurine has been shown to stimulate ceramide synthase and hyaluronic-acid synthase while suppressing MMP-1, the enzyme that breaks down collagen (Experimental and Therapeutic Medicine, 2023). Together these actions support a stronger skin barrier and better hydration, which is why this lean cephalopod offers benefits beyond its impressive protein content.
