Regardless of where you’re working from, a solid midday meal can be clutch when dinner is hours away.

I was recently asked to share some of my favorite low-lift lunch suggestions with Well + Good. I highlighted chamchi deopbap, or a simple Korean tuna rice bowl, as my top pick. And it made me realize I’ve never shared an official recipe on the blog. That needed to change!

What is Chamchi Deopbap?

In Korean, chamchi means tuna and deopbap means “over rice”. It’s a simple meal consisting of warm rice, canned tuna, kewpie mayo, and various vegetables and other toppings. It’s one of those meals that’s perfect when you don’t feel like cooking.

Technically, you could also call this recipe chamchi mayo deopbap, Korean tuna mayo deopbap, or Korean tuna mayo rice bowl and all would be more or less accurate and correct.

You can also think of is as a template with options to add other ingredients (more on that below). 

Korean Tuna Rice Bowl Ingredients

• Cooked rice. I always use a short grain or medium grain rice, like this Kokuho Rose brand. But nearly any type of rice can work, including sushi rice, jasmine rice, long-grain rice, or even instant or microwave rice. 
• Canned tuna. Again, use what you have available but if you can get to a Korean grocery store, I really recommend trying Korean canned tuna. The first time I tried it I immediately noticed a difference. The flakes are bigger and chunkier, plus it comes in a wider variety of flavors such as this one packed in kimchi juice. 
• Kewpie mayo. This Japanese-style mayo is made with egg yolks and MSG (monosodium glutamate). It’s extra rich and creamy, and helps moisten the flakes of tuna when it’s all mixed together. I much prefer this over regular mayonnaise but if that’s all you have, it works just fine.
• Kimchi, cut or sliced into bite-sized pieces
• Chopped veggies such as the matchstick carrots I used (optional, but I like the fresh crunch it adds)
• Green onions
• Toasted sesame seeds
• Gim/nori (dried and roasted sheets of seaweed) for serving

How to Make a Korean Tuna Rice Bowl

This easy meal could not be easier to build. Follow these simple steps:

1. Reheat your pre-cooked rice and layer it into the bottom of a small bowl. You’re making a single portion, so it can be a regular bowl, not a mixing bowl. If you’re making fresh steamed rice, adjust the cooking time accordingly, but you can reheat rice in the microwave in a couple of minutes or less. 
2. Use kitchen shears to cut kimchi into bite-sized pieces (as needed). Layer this on top of the rice so it starts to warm up from the heat of the rice. 
3. Next, open the can of tuna. You want to drain most or all of the liquid off so you don’t end up with soggy rice. Flake it apart and add that on top of the kimchi. 
4. Add your other veggies, including extra kimchi, and anything else you plan to use. I recommend matchstick carrots (shown here), pickled onions, or something similar that will complement the other flavors and textures. 
5. Drizzle the kewpie mayo over the top. It doesn’t have to look picture-perfect! And if you like more of a spicy kick, you can mix a little bit of gochujang with the mayo before adding it. 
6. Finally, garnish with plenty of sliced green onions and toasted sesame seeds. Grab a package of gim or nori (dried and roasted sheets of seaweed) for serving. Enjoy!

Street Smart Nutrition Tip: If you want to avoid dragging out a knife and cutting board, or just want to minimize cleanup, use kitchen shears to cut the green onions. It won’t be as uniform, but it easily gets the job done if you’re prepping this tuna rice bowl in a hurry.

Tuna Rice Bowl Swaps and Substitutions

As I mentioned, this meal is super easy to customize. Since deopbap means “over rice” you can add pretty much anything to a base of cooked rice. Here are a few suggestions:

• Top with scrambled eggs or a fried egg for added protein. Or try canned salmon, shredded rotisserie chicken, or any other protein you have on hand.
• Switch to brown rice if you’re partial to that variety.
• Add a drizzle of sesame oil, soy sauce, or scoop of gochujang (Korean red pepper paste) to mix into your bowl. Korean food features these ingredients often, so there’s absolutely no reason you can’t doctor it up when you make your version at home!
• And no Korean meal is complete without a few small side dishes for the table (banchan). Try Oi Muchim (seasoned cucumber salad) or various types of kimchi. 

There’s truly no “wrong” way to make chamchi deopbap (Korean tuna rice bowl). Just let your taste buds be your guide! I provide some estimated measurements in the recipe card below.

But just know this is a very forgiving, simple recipe that doesn’t require exact measurements. If you don’t love how it turns out, just make a few adjustments the next time you try it. Eventually you’ll land on the version that feels just right for you!

Tuna Rice Bowl Storage Tips 

​As written, this recipe assumes you’ll split a large can of tuna between two servings.

This can be great if you’re eating at home and have someone to share with, but if not, you’ll have a whole ‘nother portion ready to go. I personally think chamchi deopbap tastes best on the first go-round, but I can’t deny how convenient it is to have one that’s literally ready to eat.

Cover or seal in an airtight container. You can store it in the fridge for a few days. And remember, the texture of the rice is best when reheated, so use the microwave to heat in short increments until it’s warmed through.

I think quick meals like this are so underrated. Chamchi deopbap (Korean tuna rice bowl) has been a reliable, easy meal for years and I hope you enjoy it as much as I do!

Korean Tuna Rice Bowl FAQs

Are tuna rice bowls healthy?

Yes! This is an all-in-one meal with plenty of carbs, fat, and protein to fill you up and nourish your body.

The addition of vegetables also adds dietary fiber, crunchy textures, and extra flavor to make this meal as enjoyable as it is healthy.

Can I use brown rice instead of white rice in a tuna rice bowl?

Yes, this Korean Tuna Rice Bowl is a great way to use leftover rice of any kind.

Can I use regular mayonnaise instead of Kewpie mayo?

Yes, if you don’t have kewpie mayo, you can use regular mayonnaise…AKA, the real stuff. It’s richer and more creamy than mayo substitutes, although not as savory or tangy as Japanese-style kewpie mayo.

Can I use fresh tuna instead of canned tuna?

You can use fresh tuna instead of canned tuna for tuna rice bowls, but it adds extra prep and cooking time. Account for that as you plan your meal, and make sure you look for fresh, high quality fresh or frozen tuna to cook for this recipe.

As an alternative to cooking fresh tuna, you can also use canned salmon, canned mackerel, or any other type of canned or tinned fish you have.

Can I add other vegetables to this tuna rice bowl?

Absolutely! The more the merrier when it comes to adding more vegetables.

You can include fresh or cooked (leftover) vegetables like bell peppers, mushrooms, broccoli, corn, onions, or more traditional Asian-style vegetables. My spicy Korean cucumber salad, quick pickled cucumbers and onions, or quick pickled red onions would also be a delicious pairing.
