Chicken Katsu Musubi Recipe: How to Make Japanese Fried Chicken Rice Balls

Today I’ll show you how to make Chicken Katsu Musubi. It’s a straightforward recipe: the most challenging part is frying the katsu, but once that’s done assembling the musubi is quick. These are great for lunches the next day, but I prefer them fresh so the katsu stays crispy.

🍱 About This Recipe

I developed this recipe when I grew tired of Spam musubi. Spam is tasty, but I wanted a less processed option. Chicken katsu works wonderfully in a musubi: it’s crispy, juicy, and pairs naturally with rice. The shape of a katsu also lends itself to forming a neat rectangular musubi.

For shaping, I use an empty Spam can. A musubi mold works the same and is more convenient, but a clean, empty can is a free, effective substitute.

🍙 How To Shape Rice Using A Spam Can

An empty Spam can provides a perfect rectangular form. Moisten the inside with water, pack it with warm sushi rice, then invert and shake to release a neatly shaped rice block.

🧂 Ingredients

• Chicken: Boneless, skinless chicken thighs (or breasts). Pound to about ½-inch thickness so they cook evenly.
• Batter: A simple wet batter of eggs, all-purpose flour, salt, and black pepper. I combine egg and flour for one-step dredging.
• Panko breadcrumbs: The crispy coating that makes katsu distinctive.
• Nori sheets: Dried seaweed cut into strips for wrapping the musubi.
• Sushi rice: Short-grain rice—sticky enough to hold shape.
• Tonkatsu sauce: Store-bought or homemade; a little goes a long way on the rice.
• Oil for frying: A neutral oil with a high smoke point.

🔪 Instructions

STEP 1: Pound the chicken to an even ½-inch thickness using a meat mallet or rolling pin.

STEP 2: In a shallow dish, whisk together eggs, flour, salt, and pepper to form a wet batter that’s slightly thinner than pancake batter. Adjust with water or flour to reach the right consistency.

STEP 3: Dip the chicken in the wet batter, let excess drip off, then press it into panko breadcrumbs until well coated.

STEP 4: Heat oil to about 350°F (175°C) and fry the chicken for 4–6 minutes, or until the internal temperature reaches 165°F (74°C). Transfer to a wire rack to rest so the crust stays crisp.

STEP 5: Lay a nori strip on a clean surface. Moisten the Spam can or mold to prevent sticking, place it perpendicular to the nori, fill with about ½ cup of rice, press firmly, then remove the mold. Brush a little tonkatsu sauce on the rice, set a piece of katsu on top, and wrap the nori tightly around the musubi, sealing the edge with a touch of water.

Serve immediately for the crispiest result, or wrap and refrigerate for a packed lunch.
