I used to spend $14 a day on lunch. Every single workday.
Then I made one bento box, and I haven’t bought a sad desk salad since.
There’s a reason bento boxes have been Japan’s go-to lunch format for centuries. They’re portioned, they’re pretty, and they somehow make leftover rice and chicken feel like an event.
I’m sharing my go to teriyaki chicken bento here, but honestly this formula works for almost anything you’ve got in the fridge. Once you get the rhythm down, you’ll never look at a lunch box the same way again. 🍱
What You’ll Need
Here’s everything going into this bento. I like to think of it in four parts: protein, carb, veggies, and sauce.
For the teriyaki chicken:
- 1 lb boneless chicken thighs, cut into bite sized pieces
- 3 tbsp soy sauce
- 2 tbsp honey
- 1 tbsp rice vinegar
- 1 clove garlic, minced
- 1 tsp fresh ginger, grated
- 1 tbsp cornstarch
- 1 tbsp neutral oil (avocado or vegetable)
For the rice:
- 1 cup short grain white rice
- 1 1/4 cups water
- 1 tsp rice vinegar (optional, but I always add it)
For the veggies:
- 1 cup broccoli florets
- 1 medium carrot, sliced thin
- 1/2 cup edamame, shelled
- Sesame seeds, for garnish
Extras that make it feel special:
- 1 hard boiled egg per box
- A few slices of cucumber
- Pickled ginger, if you’re into it
Tools You’ll Need
- A bento box (any style works, but the ones with dividers save you time)
- A small saucepan for the rice
- A skillet for the chicken
- A steamer basket or microwave safe bowl for the veggies
- Measuring spoons
- A cutting board and sharp knife
Pro Tips
I’ve made more bentos than I can count at this point, so here’s what actually matters.
- Cool your rice before packing it. Warm rice creates steam, and steam turns your crisp veggies into sad, soggy veggies. Give everything 10 minutes to cool on the counter first.
- Cut your chicken pieces small and even. Bento boxes reward small bites. Big chunky pieces of chicken just don’t pack the same way.
- Don’t skip the cornstarch on the chicken. It’s what gives you that glossy, slightly sticky coating that makes teriyaki taste like teriyaki. Skip it and you’ll just have chicken in soy sauce.
- Pack wet and dry ingredients separately. Sauce touching your rice all morning turns lunch into mush. A tiny sauce container or even a folded piece of parchment paper solves this.
- Use color as your guide. If your box only has brown and beige in it, add something green or red. It’s an easy fix and it genuinely changes how appetizing the whole thing looks.
Substitutions and Variations
This recipe is flexible, which is honestly why I keep coming back to it.
- No chicken thighs? Chicken breast works, just watch your cook time since it dries out faster.
- Want it vegetarian? Swap the chicken for extra firm tofu, pressed and cubed, or tempeh.
- Gluten free? Use tamari instead of soy sauce.
- Low carb? Cauliflower rice holds up better than you’d expect here.
- Spicy version? A teaspoon of sriracha or chili crisp in the sauce takes this in a completely different direction.
- Different veggies? Snap peas, bell peppers, and shredded cabbage all work great in this format.
Make Ahead Tips
This is where bento boxes really shine for busy weeks.
- Cook a double batch of chicken and rice on Sunday. It keeps well for 4 days.
- Steam your veggies in bulk and store them separately from everything else.
- Boil a handful of eggs at once so you’re not doing it every single morning.
- Assemble the night before if you’re not a morning person. Just add sauce right before you eat, not before.
Quick Nutrition and Pairing Notes
One full bento with all the components above comes in around 450 to 500 calories, with a solid 30+ grams of protein depending on your chicken portion.
If you want more staying power, add an extra egg or a scoop of edamame. Both add protein without messing with the balance of the box.
For drinks, this pairs really well with unsweetened iced tea or sparkling water with a splash of lime. Nothing too sweet, since the teriyaki sauce already brings plenty of flavor on its own.
How to Make This Bento Box Meal
Step 1: Marinate the chicken. Mix the soy sauce, honey, rice vinegar, garlic, and ginger in a bowl. Add the chicken pieces and let them sit for at least 15 minutes, or up to overnight in the fridge.
Step 2: Cook the rice. Rinse your rice until the water runs clear. Add it to a saucepan with the water, bring to a boil, then cover and simmer on low for 15 minutes. Let it rest off heat for 5 more minutes before fluffing.
Step 3: Steam the veggies. Steam your broccoli and carrots for about 4 to 5 minutes, just until bright and tender. Add the edamame in the last minute to warm through.
Step 4: Cook the chicken. Heat oil in a skillet over medium high heat. Remove chicken from the marinade (save the liquid) and cook for 5 to 6 minutes, stirring occasionally, until it’s cooked through and starting to caramelize.
Step 5: Make the glaze. Whisk the cornstarch into the leftover marinade, then pour it into the skillet with the chicken. Stir constantly for 1 to 2 minutes until it thickens into a glossy sauce that clings to every piece.
Step 6: Cool everything. Let the rice, chicken, and veggies sit at room temperature for about 10 minutes. This step matters more than it sounds like it should.
Step 7: Pack your bento. Add rice to one section, chicken to another, and veggies to the rest. Tuck in your hard boiled egg and cucumber slices. Sprinkle sesame seeds over everything.
Step 8: Store or eat. If you’re eating same day, you’re done. If you’re meal prepping, seal it up and refrigerate.
Leftovers and Storage
- Store assembled bentos in the fridge for up to 4 days.
- Keep sauce separate if you’re prepping more than a day in advance.
- Reheat the chicken and rice for about 60 to 90 seconds in the microwave, then add cold veggies back after. This keeps the crunch intact.
- These don’t freeze well because of the veggies and egg, so stick to fridge storage only.
FAQ
Can I use brown rice instead of white? Yes, just adjust your cook time to about 40 minutes since brown rice takes longer.
Do I need a fancy bento box for this to work? Not at all. Any container with sections, or even small silicone cups inside a regular container, does the job.
Can I make this ahead for a full work week? You can prep components for the week, but I’d recommend assembling no more than 2 to 3 days at a time so everything stays fresh.
Is this good cold? The chicken and rice are great cold or reheated. The veggies are genuinely better cold and crisp, so don’t feel like you need to heat the whole box.
What if I don’t like teriyaki? Swap the sauce for a sesame ginger dressing or even just soy sauce with a little rice vinegar. The formula works with almost any sauce you love.
Wrapping Up
This bento box formula has saved me more lunch money and more sad desk salads than I can count.
Once you get the rice, protein, veggie, sauce rhythm down, you can build a bento out of almost anything sitting in your fridge.
Give this one a try this week, and let me know in the comments how yours turned out. I’d genuinely love to hear what combos you come up with. 🍱
