Spicy stir-fried octopus is a dish that excites the senses with its bold flavors, balancing heat, umami, and a touch of sweetness. The natural brininess of octopus pairs perfectly with the depth of Korean spices, creating a dish that is both vibrant and satisfying. Traditionally served over rice, it provides a delightful contrast between tender, chewy seafood and the punchy, aromatic seasoning. Every bite carries layers of flavor, making this a must-try for seafood lovers who enjoy a spicy kick.
Ingredient Breakdown
The success of this dish begins with selecting the right octopus—long-arm octopus is ideal due to its delicate texture and ability to absorb seasonings. Properly cleaning and tenderizing it ensures a pleasant chew without toughness. Essential aromatics such as garlic, ginger, and chili peppers build a robust base, infusing the dish with warmth and complexity. Soy sauce adds depth and saltiness, while onions and green onions provide natural sweetness and enhance the umami-rich profile. The signature heat and sweetness balance comes from gochugaru (Korean hot pepper flakes) and rice syrup, which work together to create a fiery yet slightly caramelized glaze. The choice of oil is also crucial; a neutral vegetable oil allows the ingredients to shine, while a finishing drizzle of toasted sesame oil brings a nutty, fragrant note that ties everything together.
Step-by-Step Cooking Guide
Preparing the Octopus
Before cooking, the octopus needs thorough cleaning to remove any grit or residue. A vigorous massage with flour or salt helps break down tough fibers while ensuring any remaining impurities are lifted from the suction cups. Once massaged, the octopus is rinsed under cold running water until it no longer feels slippery, ensuring a fresh and clean base for cooking.
Blanching for Optimal Texture
A quick blanch in boiling water firms up the octopus slightly, making it easier to slice and preventing it from becoming overly chewy during stir-frying. The octopus is submerged for just 10 to 12 seconds before being transferred to a cutting board, where it is allowed to cool briefly before being sliced into bite-sized pieces. Proper blanching helps retain the natural tenderness of the octopus while preparing it to absorb flavors more effectively.
Making the Signature Seasoning Sauce
The bold seasoning sauce is a crucial element that coats every piece of octopus, ensuring a balance of spice, sweetness, and umami. Gochugaru provides an intense, smoky heat, while soy sauce delivers the necessary savoriness. A hint of sugar rounds out the sharpness of the spice, and potato starch helps thicken the sauce, allowing it to cling beautifully to the octopus. Rice syrup introduces a glossy finish, and a touch of ground black pepper adds subtle warmth. Mixing these ingredients thoroughly ensures that every component is evenly distributed, resulting in a well-balanced sauce that enhances the overall dish.
Stir-Frying the Octopus to Perfection
The key to achieving a fragrant and well-caramelized stir-fry lies in properly heating the oil before adding the aromatics. Garlic, ginger, and chili peppers are sautéed first, releasing their intense fragrance and creating a deeply flavorful foundation. Onions and green onions follow, softening to add sweetness and depth. The octopus is then added along with the prepared seasoning sauce, quickly tossed to ensure each piece is evenly coated. Cooking over high heat for just a few minutes prevents the octopus from becoming rubbery while allowing the sauce to infuse every bite with bold, spicy goodness. A final drizzle of toasted sesame oil enhances the dish with a nutty aroma before serving.

Ingredients
1 package (1½ pounds) frozen long-arm octopus, thawed in the refrigerator
2 tablespoons flour (or salt)
7 garlic cloves, minced
2 teaspoons minced ginger
1 large Korean green onion (or 4 green onions), chopped
4 ounces onion, chopped
1 Korean spicy green chili pepper (or jalapeño), chopped
2 to 3 tablespoons vegetable oil
1 teaspoon toasted sesame oil
For the Seasoning Sauce:
¼ cup Korean hot pepper flakes (gochugaru)
3 tablespoons soy sauce
1 tablespoon sugar
1 tablespoon potato starch (or cornstarch)
¼ cup rice syrup
½ teaspoon ground black pepper
Instructions
Begin by preparing the octopus. Slice open the heads and remove the intestines and beaks. Place the octopus in a large mixing bowl, sprinkle with flour, and vigorously massage for about 2 minutes. This step is essential for both tenderizing and thoroughly cleansing the octopus, removing any residual grit from the suction cups. Rinse well under cold running water until the texture is no longer slippery. Drain completely.
Bring a pot of water to a rolling boil. Quickly blanch the octopus for 10 to 12 seconds, then remove and transfer to a cutting board. Allow it to cool slightly before slicing the arms and heads into bite-sized pieces. Set aside.
Make the Seasoning Sauce:
In a small bowl, combine the hot pepper flakes, soy sauce, sugar, potato starch, rice syrup, and ground black pepper. Mix thoroughly with a spoon until well blended, ensuring the starch dissolves evenly into the mixture.
Stir-Fry the Dish:
Heat a large pan over high heat and add vegetable oil. Once the oil is shimmering, toss in the garlic, ginger, chili pepper, onion, and green onion. Stir-fry for about 3 minutes, allowing the garlic to turn golden and the onions to soften and become translucent.
Add the prepared octopus along with the seasoning sauce. Stir everything together for 2 to 3 minutes, ensuring each piece is evenly coated and absorbs the bold, spicy flavors. Remove from heat and drizzle in the toasted sesame oil, mixing well.
Transfer the stir-fried octopus to a serving plate and serve immediately with a bowl of warm rice.
