Ojingeo-bokkeum (오징어볶음) is one of the most popular Korean stir-fried dishes: fresh squid coated in a gochujang-based sauce and stir-fried over intense heat with onion, courgette, and green onion until the squid takes on a slightly charred edge and the sauce thickens to a glossy, lacquered coating. The technique requires high heat to achieve the characteristic char and caramelisation — a pan that is not sufficiently hot will steam the squid rather than sear it, producing tough, watery results. The squid must be prepared with diagonal cross-hatching on the tube and cut to size before cooking to promote even heat penetration and sauce adhesion.

The Method
1
Score the squid tubes diagonally in a crosshatch pattern, cutting through roughly two-thirds of the flesh without piercing the other side, so that the cuts open dramatically on contact with heat and give the sauce far more surface to cling to. Cut the scored tubes into bite-sized pieces. Leave tentacles whole or halved.
2
Combine all sauce ingredients — gochujang, gochugaru, ganjang, sesame oil, sugar or maesil-cheong, and minced garlic — in a bowl and mix to a uniform paste. Premix completely before any heat is applied, so that the moment the paste hits the hot pan it caramelises as one rather than scorching in patches where the gochujang lands first.
3
Set a wok or heavy pan over the highest available heat, add the neutral oil, and continue heating until the pan is visibly smoking, because a pan that falls short of this will draw moisture out of the squid and steam it to a pale, watery, and tough result rather than searing it. This is where the dish lives or dies: the oil should shimmer and produce wisps of smoke before anything enters the pan.
4
Add the onion and courgette to the smoking pan and stir-fry over sustained high heat until the onion is translucent at its edges and the courgette has taken a little colour but retains structure. Cook them through completely at this stage, because the squid will spend only seconds in the pan and cannot carry the vegetables to doneness.
5
Add the squid and pour the premixed sauce over in a single addition, tossing everything together continuously over high heat so the paste coats and lacquers rather than sitting and burning on one side. The squid is done when the crosshatch cuts have opened and curled, the sauce has thickened to a glossy coating, and the edges of the squid show the first signs of char — the total time from squid entering the pan to removal must not exceed 90 seconds, beyond which toughening is inevitable.
6
Add the green onion batons in the final seconds of cooking and toss once, keeping them in the pan just long enough to lose their raw sharpness while holding their colour and a faint bite. Remove the pan from the heat immediately.

Quality Hierarchy
01
Reserve — Day-boat fresh squid, scored and cut to order; maesil-cheong in place of sugar; artisan single-batch gochujang.
02
Estate — Fresh squid purchased the morning of cooking; maesil-cheong; CJ Haechandle gochujang as cited in the source.
03
Market — Fresh squid from a fishmonger; standard supermarket gochujang; sugar in place of maesil-cheong.
04
House — Frozen squid, thoroughly thawed and patted very dry to reduce moisture release; any available gochujang. Expect a less lacquered, potentially watery sauce.

Sensory Tests
◇Sight. The pan produces visible wisps of smoke before any ingredient is added — the minimum threshold for searing rather than steaming.
◇Sight. The crosshatch cuts on the squid tubes have opened and the pieces have curled, indicating sufficient heat penetration.
◇Sight. The sauce has reduced to a glossy, lacquered coating that clings to each piece of squid and vegetable without pooling at the base of the pan.
◇Sight. The edges of the squid carry the first signs of char — faint browning that signals caramelisation without overcooking.
◇Where it lives or dies. The pan must be smoking hot before the squid enters; anything less steams the squid in its own moisture, producing a watery, pale, and irreversibly tough result.

Chinese 辣炒鱿鱼 (stir-fried squid with doubanjiang) — fermented chilli paste, high heat, fast cook; the structural template shared with ojingeo-bokkeum. Thai pad prik squid (stir-fried squid with chilli and basil) — the same high-heat, short-window, fermented-chilli approach applied to squid across Southeast Asian tradition.

Pan-Korean. Ojingeo-bokkeum is a staple banchan and simple lunch dish found in every Korean household regardless of region, with no single provincial claim of origin. It appears equally as a standalone banchan and as ojingeo-bokkeum-bap — the squid served over rice in the 덮밥 (dolsot) manner.
