Tuna Mayo Rice Bowl (Chamchi Mayo Deopbap)

This is the dish every Korean college student and young professional knows by heart—chamchi mayo deopbap, a dead-simple tuna mayo rice bowl you can throw together in under five minutes with pantry staples. It’s not fancy restaurant food; it’s survival cooking that happens to taste great. When you’re too tired to cook or just craving something comforting and savory, this bowl delivers with minimal effort and maximum satisfaction.

Prepare the Tuna Mayo Mixture

Open your can of tuna and drain it very well—press it against the lid or use a fork to squeeze out excess liquid. Soggy tuna makes a watery bowl. Transfer the drained tuna to a small bowl.

Add the mayonnaise, soy sauce, and sesame oil to the tuna. Mix thoroughly with a fork, breaking up any large chunks until everything is evenly combined and creamy. The mixture should hold together but still be fluffy, not pasty. Taste it—if you want more richness, add a pinch more mayo; if you want more savory depth, add a few drops of soy sauce.

💡 Tip: Tuna packed in oil has more flavor, but if you only have water-packed, add an extra ½ teaspoon of sesame oil to boost richness.

Fry the Egg

Heat a small nonstick pan over medium heat and add a drizzle of neutral oil. Crack the egg into the pan and cook for 2–3 minutes until the whites are fully set but the yolk is still runny. You want that golden yolk to break and coat the rice when you dig in. If you prefer a fully cooked yolk, cover the pan with a lid for the last minute or flip the egg gently.

Season the egg lightly with a pinch of salt or a few drops of soy sauce while it’s still in the pan.

Assemble the Bowl

Spoon the warm rice into your serving bowl. If your rice is cold, microwave it for 30–60 seconds—this dish is best with warm, fluffy rice.

Place the seasoned tuna mayo mixture on top of the rice in a generous mound. Slide the fried egg on top of the tuna. Crumble or tear the roasted seaweed sheet over everything, then scatter the sliced green onion and sesame seeds on top.

Drizzle a small amount of soy sauce over the egg and rice (start with about 1 teaspoon—you can always add more). If you like a little heat, add a pinch of black pepper or a dab of gochugaru (Korean red pepper flakes).

Mix and Eat

The magic happens when you break the egg yolk and mix everything together with your spoon. The runny yolk, creamy tuna mayo, soy sauce, and rice all blend into a rich, savory, umami-packed bite. Don’t be shy—stir it all up thoroughly so every grain of rice gets coated.

Eat it straight from the bowl while it’s warm. This is the kind of meal that hits different late at night or when you need something fast and satisfying.

Serving Suggestions and Substitutions

Serve this bowl on its own for a quick solo meal, or pair it with a simple cucumber salad or kimchi on the side for contrast. A cold glass of barley tea (boricha) or water is all you need.

Substitutions: If you can’t find Korean roasted seaweed (gim), use Japanese nori sheets—they’re nearly identical. No sesame oil? A tiny drizzle of toasted nut oil works, or just skip it and add a bit more mayo. If you want extra vegetables, toss in some shredded lettuce, sliced cucumber, or avocado on top before mixing. For a spicy version, stir ½ teaspoon of gochujang (Korean red pepper paste) into the tuna mayo mixture.

This is adaptable, forgiving, and exactly the kind of no-stress cooking that makes Korean student food so beloved. Keep a couple cans of tuna and seaweed in your pantry, and you’ll always have a solid meal five minutes away.
