Ingredients

Boneless skinless chicken thighs 450g, cut into 2.5cm bite-sized pieces
Uncooked short-grain white rice 360g (2 US cups)
Low-sodium soy sauce 60ml (1/4 cup)
Mirin 45ml (3 tbsp)
Sake (dry white wine as substitute) 30ml (2 tbsp)
Granulated sugar 16g (1 tbsp + 1 tsp)
Broccoli florets 200g
Carrot 120g (1 medium), cut into matchsticks
Cucumber 150g (1 medium), thinly sliced
Rice vinegar 30ml (2 tbsp)
Table salt 6g (1 1/4 tsp)
Toasted white sesame seeds 9g (1 tbsp)
Vegetable oil 15ml (1 tbsp)
Large eggs 100g (2 units)

Steps

1

Cook the short-grain rice

Rinse 360g uncooked short-grain white rice under cold running water for 2 minutes until runoff water is completely clear, then add to a rice cooker with 480ml (2 cups) cold water. Cook on the standard white rice setting for 20 minutes, then let rest, covered, for 10 minutes before fluffing with a bamboo rice paddle. Stir in 5ml (1 tsp) rice vinegar and a 1g pinch of salt, then set aside to cool to room temperature.

2

Prep quick pickled vegetables

Combine 120g matchstick-cut carrot and 150g thinly sliced cucumber in a small glass bowl. Toss with 25ml (1 tbsp + 2 tsp) rice vinegar, 4g (1 tsp) granulated sugar, and 2g (1/2 tsp) salt until evenly coated. Let rest at room temperature for 15 minutes, stirring once at the 7-minute mark, then drain all excess brine before assembly.

3

Sear the chicken thighs

Heat 15ml (1 tbsp) vegetable oil in a large non-stick skillet over medium heat (175°C/350°F). Pat 450g bite-sized chicken thigh pieces completely dry with paper towels, then arrange in a single, uncrowded layer in the skillet. Cook for 4 minutes per side, until deep golden brown on all sides and internal temperature reaches 74°C/165°F.

step3:Sear the chicken thighs

Glaze chicken with teriyaki

Whisk 60ml low-sodium soy sauce, 45ml mirin, 30ml sake, and 8g (2 tsp) granulated sugar in a small bowl until sugar dissolves, then pour the mixture over the seared chicken. Reduce heat to medium-low (150°C/300°F) and simmer for 3 minutes, stirring occasionally, until the glaze thickens to a syrupy consistency and coats every chicken piece. Turn off heat and toss with 4.5g (1/2 tbsp) toasted sesame seeds.

5

Blanch the broccoli florets

Bring 1L (4 cups) of water mixed with 2g (1/2 tsp) salt to a rolling boil over high heat. Add 200g broccoli florets and cook for exactly 2 minutes until bright, vivid green and crisp-tender. Use a slotted spoon to immediately transfer broccoli to a bowl of ice water for 1 minute to stop cooking and lock in color, then drain fully and pat dry with paper towels.

Step 5
step5:Blanch the broccoli florets
6

Make sweet rolled omelet

Whisk 2 large eggs with 4g (1 tsp) granulated sugar and a 1g pinch of salt until fully smooth with no streaks of egg white. Heat a small non-stick skillet (or tamagoyaki pan) over low heat (135°C/275°F), lightly coat with a thin wipe of oil, then pour a thin 1/4 layer of egg to cover the pan base. Once the egg is just set (1 minute), roll it into a tight log from one pan edge to the other, push the log back to the starting edge, add another thin layer of egg, and repeat until all egg is used. Let the rolled omelet cool for 2 minutes, then slice into 2.5cm thick pieces.

7

Assemble the bento boxes

Divide the cooled rice evenly across 4 lidded, divided bento boxes, filling roughly 1/3 of each box’s total space. Add a 110g portion of teriyaki chicken to a second section, then fill the remaining divided spaces with equal portions of drained pickled vegetables, dried blanched broccoli, and sliced sweet omelet. Sprinkle the remaining 4.5g (1/2 tbsp) toasted sesame seeds over the rice and chicken, then seal lids tightly until ready to eat.

Tips

1.Always pat chicken dry with paper towels before searing; excess moisture will cause the chicken to steam instead of brown, leading to a soft exterior that won’t hold the teriyaki glaze properly.
2.Let all cooked components cool to near room temperature before sealing the bento lid; trapped hot steam will create condensation that makes rice mushy and vegetables soggy during storage.
3.If your bento box doesn’t have built-in dividers, use small silicone baking cups or food-safe paper liners to separate strong-flavored items like pickled vegetables from milder rice and sweet omelet.

Bento Box:Frequently Asked Questions

1.Can I use boneless, skinless chicken breasts instead of thighs for this teriyaki chicken?
You absolutely can, but thighs are ideal for bento because their higher fat content stays juicy and flavorful even when chilled for hours ahead of eating. If you use breast, pound it to an even ½-inch thickness, marinate 10 extra minutes, cook 2–3 minutes less to avoid dryness, and always slice against the grain before packing for the most tender bite.
2.I don’t keep mirin or sake stocked—what easy pantry swaps work for the teriyaki sauce?
For sake, use equal parts dry white wine (the recipe’s noted substitute!) or low-sodium chicken broth with a small pinch of extra sugar to match its mild, fermented depth. For mirin, swap 1 tablespoon dry white wine plus 1 teaspoon granulated sugar per tablespoon of mirin to get that perfectly balanced sweet-savory teriyaki glaze without an artificial aftertaste.
3.How do I pack the bento so teriyaki sauce doesn’t make the rice soggy by lunchtime?
First, let every cooked component (chicken, rice, rolled egg) cool fully to room temperature before sealing the box—trapped hot steam creates excess moisture that sogs out food. Tuck a small wax paper liner under the sliced chicken to catch extra glaze drips, and nestle tangy quick pickles in a divider or tiny silicone cup to keep their brine separate.
4.Can I use regular long-grain white rice instead of short-grain for this bento?
Short-grain rice is traditional for bento because its slightly sticky, fluffy texture holds together well for portable meals and pairs perfectly with savory teriyaki glaze. If you only have long-grain on hand, you can absolutely use it—just reduce cooking water by 1 tablespoon per cup of rice to avoid mushy grains, though it won’t have that classic soft, cohesive bento rice texture.

Took a chance on this for my partner’s birthday bento picnic and it was a massive hit! The teriyaki glaze has that perfect balance of sweet and salty, not that cloying store-bought teriyaki taste I’m used to. I added a little extra steamed broccoli and pickled ginger on the side and it felt like we picked it up from our favorite local Japanese spot. 10/10

So glad it worked out for your picnic! Adding extra veggies and pickled ginger is such a smart call to round out the bento, love that idea.

Super easy recipe, perfect for beginners! I was nervous I’d mess up the teriyaki sauce but it came together in like 5 minutes, no fancy ingredients needed. The chicken got that nice crispy edge just like the recipe said, no burnt bits at all. Great weeknight dinner option.

Wait, does anyone know if I can swap the chicken thighs for chicken breast? I only have breast in the freezer right now and don’t wanna run to the store in the rain lmao

30 minutes ago

I did that last week! Just pound the breast to even thickness so it doesn’t dry out, and maybe let it marinate 10 extra minutes. Turned out great for me!

5 minutes ago

Great tip from RamenFan99! You can absolutely use chicken breast here — just keep an eye on the cook time so it doesn’t overcook, since breast is leaner than thighs. Happy cooking!

Brought these mini bento boxes to my office potluck last week and people were literally begging for the recipe! I cut the chicken into bite-sized pieces for easy serving, and paired it with the rice and a little edamame just like the recipe suggested. Even my boss who’s super picky about Asian food went back for a third helping lmao

5 days ago

That makes us so happy to hear! Bite-sized pieces are such a perfect tweak for potlucks, no forks required basically. Genius call!

Made this for a day hike last weekend, packed it in our insulated bento boxes and it held up perfectly even after 3 hours in the pack. The glaze didn’t get all runny, the rice stayed fluffy, zero sogginess. Way better than packing sad granola bars for trail lunch, will definitely be a regular on our hike rotation.

Wait, cook time says 40 minutes — is that accurate? I have exactly 45 minutes between getting home from work and taking my oldest to soccer practice, so I need something I can crank out fast without rushing.

yesterday

I timed it last night! 38 minutes flat for me, and that included making the rice and steaming a side of veggies. You’ve totally got time, just have your ingredients pre-measured before you start and it’s a breeze.

2 hours ago

That time is spot on! Most of the cook time is passive while the rice simmers and the chicken glazes, so you won’t be stuck running around the kitchen the whole 40 minutes. It’s perfect for busy weeknights!

5 days ago

Full transparency: I burn 90% of the Asian recipes I try because I’m terrible at balancing sauces, but this one was foolproof! The teriyaki measurements are so straightforward, no weird guesswork, and it tasted just like the bento I used to get from the food truck near my old college apartment. I’m actually proud of myself for pulling this off lmao

3 days ago

Same! I’m the worst at making sauces from scratch but this one was so easy, I didn’t even mess it up on my first try. The key is just not walking away from the pan when the glaze is thickening, right?

Quick question! Can I make this gluten free? My roommate has celiac and I wanna make this for our weekly roommate dinner night without making her sick.

2 days ago

Absolutely! Just swap the regular soy sauce for tamari (make sure it’s certified gluten free) and it works perfectly. The flavor is almost identical, no one will even notice the swap!

I collect cute bento boxes and have been looking for recipes that actually look as good as they taste to pack in them, and this one delivered! I arranged the chicken, rice, a little onigiri, some carrot flowers and cucumber slices next to it and it looked straight out of a food magazine. So fun to make, even more fun to eat.

30 minutes ago

Uh, quick dumb question… when the recipe says to glaze the chicken, do I just pour the sauce over it while it’s in the pan? I’ve never made teriyaki before and I don’t wanna mess it up 😅

5 minutes ago

No dumb questions! Yep, once the chicken is almost cooked through, pour the mixed sauce in the pan and toss the chicken around as it simmers for a couple minutes. It’ll thicken up and coat every piece perfectly, just stir it so it doesn’t stick.

Perfect explanation from HomeCookHero! Just make sure your heat is on medium-low when you add the sauce so the sugar in the glaze doesn’t burn, and you’ll be golden. It’s way easier than it sounds, promise!

How long do these keep in the fridge for? I usually prep 5 days of lunches on Sunday and wanna know if this will hold up through Friday.

5 days ago

Stored in an airtight container, this bento will keep for up to 4 days in the fridge! I usually recommend prepping Sunday for Monday-Thursday lunches to keep everything at peak freshness, but it’ll still taste great on Friday if you don’t mind the rice being a tiny bit firmer.

Added a teaspoon of chili garlic sauce to the teriyaki glaze for a little kick and it was *chef’s kiss*. If you like a tiny bit of heat with your sweet and savory, do yourself a favor and try that tweak. Game changer level good, I’ll never make plain teriyaki again.

OMG you guys, my kids are so picky about chicken, they usually turn their noses up at anything that’s not plain nuggets, but they both devoured this last night! My youngest even asked if we could have it for breakfast this morning, which is the highest possible compliment in our house. SO good!

yesterday

Same here! My 6 and 9 year old went crazy for it, I think the slightly sweet glaze is what hooked them. I even let them help mix the teriyaki sauce and they thought that was the coolest thing ever.

30 minutes ago

There’s no better review than a kid asking for leftovers for breakfast! Getting kids involved in mixing the sauce is such a fun way to get them excited about trying new foods, love that idea.

I was gonna pay $18 for a bento box from the place down the street for my lunch today, but decided to try making this instead and it tasted better than takeout! Total cost per portion was like $3, I’m never ordering takeout teriyaki again lmao

2 hours ago

The cost savings are insane right? I did the math too, it’s a fraction of what takeout costs and you can control exactly what goes in it, no weird added preservatives or too much sugar. I make this every other week now!

Wait, can I cook the chicken in the air fryer instead of pan frying it? I use my air fryer for literally everything and hate cleaning extra pans if I don’t have to.

2 days ago

I did this! Cooked the chicken at 380F for 12 minutes, flipping halfway, then brushed the glaze on the last 2 minutes of cook time. It came out so crispy, even better than pan fried in my opinion, and way less cleanup!

yesterday

Thanks for sharing that hack Mia! Air fryer teriyaki chicken is such a great low-mess alternative, we might have to add that tip to the recipe notes for fellow air fryer fans.

Made this for my at-home date night with my girlfriend last weekend, set out little divided plates with the chicken, rice, miso soup, and mochi for dessert, and she said it was better than the fancy Japanese restaurant we went to for our anniversary. Total win, 10/10 will make again to impress people lmao

5 minutes ago

I usually hate leftover chicken because it gets all rubbery and weird, but this was actually even better the next day! The glaze soaked into the chicken a little more and the flavors melded so well, I fought my roommate for the last portion at lunch today lmao

just now

We love hearing that! A lot of teriyaki recipes actually taste better the next day as the flavors develop, which makes it perfect for meal prep. Glad you and your roommate enjoyed it!
