These Korean Rice Balls, known as Jumeokbap (주먹밥), are the ultimate savory treat. They are incredibly simple to make, packed with flavor, and perfect for a quick lunch, a satisfying snack, or a fun appetizer. If you’re looking for a versatile and delicious way to use leftover rice, you’ve found the perfect recipe.
Jumeokbap translates to “fist rice,” which perfectly describes how these delightful bites are made. They are a staple in Korean households, often packed in lunchboxes for both kids and adults. Their charm lies in their simplicity and their endless possibilities for customization.
What Are Korean Rice Balls (Jumeokbap)?
At their core, Korean Rice Balls are seasoned short-grain rice mixed with various ingredients and rolled into bite-sized balls. The most common seasoning includes toasted sesame oil, sesame seeds, and roasted seaweed flakes (gim). This simple combination creates a nutty, savory flavor that is irresistibly delicious.
Unlike Japanese onigiri, which often has a single filling in the center, jumeokbap typically has all the ingredients mixed evenly throughout the rice. This ensures you get a burst of flavor in every single bite.

Essential Ingredients
The beauty of this Korean rice balls recipe lies in its simple, yet flavorful ingredients. Here’s what you’ll need for the base:
- Short-Grain Rice: This is crucial. The higher starch content helps the rice balls stick together. Japanese-style sushi rice or Korean short-grain rice is perfect.
- Toasted Sesame Oil: Adds a rich, nutty aroma and flavor that is quintessentially Korean.
- Roasted Seaweed Flakes (Gim): You can buy pre-shredded roasted seaweed (gimjaban) or simply crush seaweed snack sheets.
- Toasted Sesame Seeds: These add a wonderful texture and boost the nutty flavor.
- Salt: Just a pinch to bring all the flavors together.
For the Tuna Mayo Filling:
- Canned Tuna: Drained well to avoid making the rice balls soggy.
- Mayonnaise: Use a good quality mayonnaise for the best creamy texture. Japanese Kewpie mayo is a great option if you can find it.
- Optional additions: A little sriracha for heat, or finely chopped scallions for freshness.
How to Make Korean Rice Balls (Step-by-Step)
Making Jumeokbap is a straightforward process. Just follow these simple steps for perfect results every time.
- Cook the Rice: First, cook the short-grain rice according to the package directions. For best results, use a rice cooker. The rice should be sticky and fluffy.
- Season the Rice: While the rice is still warm, transfer it to a large mixing bowl. Add the toasted sesame oil, roasted seaweed flakes, toasted sesame seeds, and a pinch of salt. Gently fold everything together until the ingredients are evenly distributed. Be careful not to mash the rice grains.
- Prepare the Filling: In a separate small bowl, combine the drained canned tuna and mayonnaise. Mix until well combined and creamy.
- Combine: Add the tuna mayo mixture to the seasoned rice. Gently mix until the tuna is evenly incorporated throughout the rice.
- Shape the Rice Balls: Lightly wet your hands with water or wear food-grade gloves to prevent sticking. Scoop a small amount of the rice mixture (about 2-3 tablespoons) into your palm. Gently press and roll into a compact, bite-sized ball.
- Serve and Enjoy: Your Korean rice balls are ready to be served immediately at room temperature.

Pro Tips for Perfect Rice Balls
- Use Fresh, Warm Rice: Warm rice is more pliable and easier to shape. It also absorbs the seasonings better than cold rice.
- Don’t Over-Mix: Gently fold the ingredients into the rice to avoid a mushy texture.
- Control Moisture: Always squeeze out excess liquid from fillings like tuna or kimchi to prevent the rice balls from becoming soggy and falling apart.
- Taste and Adjust: Before you start rolling, taste the rice mixture and adjust the seasoning if needed. It might need a little more salt or sesame oil.
What to Serve with Jumeokbap
Korean rice balls are fantastic on their own, but they also pair wonderfully with other dishes. Serve them alongside a spicy soup, a fresh salad like our Beet and Cucumber Salad, or with Korean side dishes (banchan) like pickled radish and kimchi for a complete meal.
Storage Instructions

The main difference lies in how the ingredients are incorporated. In Jumeokbap, the fillings and seasonings are mixed evenly throughout the rice. In Japanese Onigiri, the rice is typically lightly salted and shaped around a central filling.
