Korean rice cakes, or tteok, are chewy rice-based cakes used in dishes such as tteokbokki, a popular Korean preparation simmered in a spicy-sweet sauce. For this recipe, soak frozen cylindrical rice cakes for 20 minutes, then simmer them in the sauce for 10 minutes; refrigerated cakes usually need only about 8–10 minutes of simmering. The exact time depends on their shape, thickness, and whether they start frozen or thawed.
Ingredients
- 1 lb (450 g) frozen cylindrical Korean rice cakes (garaetteok), ideally separated into individual pieces. This recipe is timed for frozen cakes; refrigerated cakes can be used without the soaking step.
- 2 cups (480 ml) water, to make enough sauce to coat the rice cakes and keep them tender as they simmer.
- 2 tablespoons (30 g) gochujang, Korean fermented chili paste. If unavailable, use 1 tablespoon (15 g) sambal oelek plus 1 teaspoon (5 g) miso and 1 teaspoon (4 g) sugar; the sauce will taste less fermented and may be thinner.
- 1 tablespoon (6 g) gochugaru, Korean red pepper flakes. Substitute ½–1 teaspoon (1–2 g) crushed red pepper for a sharper, less fruity heat, adjusting to taste.
- 1 tablespoon (15 ml) soy sauce, for savory depth.
- 1 tablespoon (12 g) granulated sugar, to balance the chili paste. Use 2 teaspoons (8 g) for a less sweet sauce.
- 1 small garlic clove (3 g), finely minced, or ½ teaspoon (2 g) garlic powder.
- 2 scallions (about 30 g), thinly sliced, with the white and green parts separated if you like.
- 1 teaspoon (3 g) toasted sesame seeds, optional, for serving.
Instructions
- Soak the frozen rice cakes for 20 minutes. Put them in a bowl and cover with cold water while you measure the sauce ingredients and slice the scallions. Separate any pieces that are stuck together as they soften. Drain them before cooking. If using refrigerated, soft rice cakes, skip the soak and rinse briefly if they are dusty or clinging together. The recipe’s prep time includes the 20-minute soak plus about 5 minutes of active measuring and cutting.
- Mix the sauce. In a wide skillet or shallow saucepan, whisk together the water, gochujang, gochugaru, soy sauce, sugar, and garlic. A wide pan lets the cakes sit in a fairly even layer and makes it easier to stir without breaking them. The sauce may look thin at this point; it will reduce as it simmers and cling more closely to the rice cakes.
- Bring the sauce to a simmer, about 2 minutes. Set the pan over medium-high heat and stir until the gochujang dissolves. When the sauce begins bubbling across the surface, add the drained rice cakes. Avoid leaving the pan unattended: a sugary chili sauce can catch on the bottom if the heat is too high or the liquid reduces too quickly.
- Simmer the rice cakes for 10 minutes. Reduce the heat to medium or medium-low so the sauce bubbles gently. Stir every minute or two, scraping the bottom of the pan, and turn the cakes so they cook evenly. If the sauce becomes thick before the centers are soft, add water 1 tablespoon (15 ml) at a time. If the cakes are still firm after 10 minutes, continue in 1-minute increments rather than raising the heat.
- Finish with the scallions for 2 minutes. Stir in the white parts of the scallions during the final 2 minutes of cooking, then add the green parts just before serving. The rice cakes are ready when they are hot through, soft and springy rather than hard in the center, and coated in a glossy sauce. The full cooking time is about 14 minutes: 2 minutes to bring the sauce to a simmer, 10 minutes to cook the cakes, and 2 minutes to finish. Sprinkle with sesame seeds if using.
Tips
- Use the right shape. This timing is for cylindrical garaetteok, whether long pieces cut into shorter lengths or short tubes. Thin oval rice cakes used in tteokguk cook faster, often in about 3–5 minutes in a simmering soup, so follow the package and check early.
- Soak only when needed. Frozen cakes can have a firm or dry center if they go straight into a thick sauce. A 20-minute cold-water soak helps them cook more evenly. Soft, refrigerated cakes generally need no soaking; if they feel especially stiff, soak them for 10 minutes and start checking before the full cooking time.
- Keep the simmer gentle and stir. A hard boil can make the sauce reduce before the centers soften, while frequent gentle stirring helps prevent sticking. Add a splash of water if the pan looks dry; simmer a little longer with the lid off if the sauce is too thin.
- Check package directions and freshness. Rice cakes vary in thickness, moisture, and processing. Use the package’s storage and preparation guidance when available, and rely on texture—not only the clock—to decide when they are done.
Serving Suggestions
Serve tteokbokki hot as a shared snack, a casual lunch, or a simple dinner. The chewy cakes and chili sauce are filling, so a bowl can be served on its own or divided alongside steamed rice and a mild vegetable side such as cucumber salad, blanched greens, or lightly dressed cabbage. A side dish with a cool, crisp texture provides contrast to the warm, sticky sauce.
For a meal with more variety, put the rice cakes in a shallow serving bowl and spoon extra sauce over the top. Offer sliced scallions and sesame seeds at the table so each person can add them to taste. If serving more than two people, scale the ingredients proportionally and use a wide pan; crowded cakes are harder to stir and may cook less evenly. Keep extra sauce in the pan rather than letting the cakes sit uncovered for a long time, since they continue absorbing liquid as they cool.
Variations
Milder sauce: Reduce the gochugaru to ½ teaspoon (1 g) or leave it out, then taste before adding more. Gochujang itself has some heat, so omitting the flakes softens the dish without removing all of its chili flavor. For a sweeter, less spicy version, add another teaspoon (4 g) of sugar and a little water if needed to keep the sauce loose.
More vegetables: Add ½ cup (50 g) thinly sliced cabbage or ½ cup (60 g) sliced onion with the rice cakes. These vegetables release moisture and soften as they cook, so the sauce may take a minute or two longer to thicken. Add a small splash of water if it gets too concentrated before the vegetables are tender.
Use another rice-cake shape: Thin oval rice cakes can replace cylindrical ones, but they need less time and are easier to overcook. Add them after the sauce is simmering and start checking after 3 minutes; many are ready in 3–5 minutes, depending on thickness and whether they are frozen or thawed. For any shape, stop cooking when the center is tender and pleasantly chewy.
Adjust the sauce consistency: For a saucier result, stir in ¼ cup (60 ml) water near the end and warm it through. For a thicker, more concentrated coating, simmer uncovered for another minute or two, stirring continuously. The sauce thickens as it cools, so take the pan off the heat while it is still a little looser than you want on the plate.
Storage and Reheating
For food safety, refrigerate cooked rice cakes within 2 hours. Store leftovers in a covered container in the refrigerator for 3–4 days. The rice cakes firm up as they cool and may absorb much of the sauce; this change in texture is normal, though the leftovers will be less springy than freshly cooked tteokbokki.
Reheat a portion in a skillet over low to medium-low heat with 1–3 tablespoons (15–45 ml) of water. Stir gently until the sauce loosens and the rice cakes are hot throughout. USDA FSIS guidance is to reheat leftovers to 165°F (74°C); use a food thermometer to check. A microwave also works: cover loosely, heat in short bursts, and stir between bursts, adding a little water if the sauce becomes sticky. Avoid repeated reheating and cooling; warm only the portion you plan to eat. For longer storage, freeze cooled portions in an airtight container for up to 2 months for best quality, then thaw overnight in the refrigerator and reheat with added water.
Frequently Asked Questions
How long do Korean rice cakes take to cook?
Frozen cylindrical rice cakes in this recipe soak for 20 minutes and then simmer for about 10 minutes once the sauce is bubbling. The sauce takes about 2 minutes to reach a simmer, and the scallions cook for another 2 minutes, making the stove time about 14 minutes. Refrigerated cylinders often take 8–10 minutes of simmering, while thin oval rice cakes can be ready in 3–5 minutes.
Do I have to soak frozen rice cakes before cooking?
Soaking is helpful but not always essential. A 20-minute cold-water soak loosens frozen cakes and helps them soften evenly, especially if they are stuck together. If you cook them from frozen, allow extra time, keep the sauce loose with small additions of water, and check that the centers are tender before serving.
How can I tell when rice cakes are done?
They should be hot through, soft enough to bite without a hard or chalky center, and still pleasantly chewy. Lift one out and cut or bite through it to check the middle. If it is firm, simmer for another minute and check again; cooking time varies with the cake’s thickness and starting temperature.
Why are my Korean rice cakes hard or tough?
They may be undercooked, especially if they started frozen or were thicker than the pieces used for the recipe timing. Add a little water and continue at a gentle simmer until the center softens. Rice cakes can also harden as they cool, so serve them soon after cooking and loosen leftovers with water when reheating.
Can I cook rice cakes without soaking them?
Yes. Soft refrigerated rice cakes can usually go directly into simmering sauce. Frozen cakes can also be cooked without soaking, but they may need several extra minutes and are more likely to soften unevenly. If they are frozen into a solid clump, soak them first so you can separate the pieces and stir them easily.
Can I use tteokguk rice cakes for tteokbokki?
Yes, thin oval rice cakes can be used, although their shape and texture differ from the cylindrical cakes traditionally used for this style of tteokbokki. Because they are thinner, add them to the simmering sauce later and check after 3 minutes. They may be tender in 3–5 minutes, so avoid automatically using the full 10-minute simmer for cylinders.
