Silas opened his lunch bag at work one day and a coworker literally got up from his desk to come look at it.
That’s not an exaggeration. He came back that night laughing about it, saying “people think I have a personal chef now.”
I mean, kind of. 😊
That lunch was a simple bento box. Teriyaki chicken, rice, a little pile of edamame, some pickled cucumbers. Took me about 25 minutes to make on a Sunday.
And ever since that “personal chef” comment, bento boxes have become our go-to for weekday lunches. They’re endlessly customizable, they reheat well, and they somehow make plain old lunch feel like an event.
If you’ve never made one, this is your sign. I’m walking you through my favorite version, plus everything I’ve learned from months of trial and error (including a few soggy rice disasters I’d rather forget).
Side Note: If you’re into easy make-ahead lunches, you might also like my Mexican corn salad for pairing with these.
What You’ll Need
Here’s everything that goes into one batch, which makes about 4 bento boxes.
| Ingredient | Amount |
|---|---|
| Boneless chicken thighs | 1.5 lbs |
| Soy sauce | 1/3 cup |
| Brown sugar | 3 tbsp |
| Rice vinegar | 1 tbsp |
| Garlic, minced | 3 cloves |
| Fresh ginger, grated | 1 tbsp |
| Cornstarch | 1 tsp |
| Sesame oil | 1 tsp |
| White rice, uncooked | 2 cups |
| Edamame, shelled | 1 cup |
| Carrots, julienned | 1 cup |
| English cucumber | 1, sliced |
| Rice vinegar (for pickling) | 1/4 cup |
| Sugar (for pickling) | 1 tbsp |
| Salt (for pickling) | 1/2 tsp |
| Sesame seeds | for topping |
| Green onions, sliced | for topping |
That’s it. Nothing exotic, nothing you can’t find at a regular grocery store.
Tools You’ll Need
- Large skillet or wok
- Rice cooker (or a pot with a lid)
- Small mixing bowls
- Sharp knife for julienning
- Bento boxes or meal prep containers with dividers
Pro Tips
I’ve made this recipe enough times to know exactly where people mess up. Here’s what I’d tell a friend making it for the first time.
- Thigh meat over breast, every time. Chicken breast dries out by day 3 in the fridge. Thighs stay juicy even reheated.
- Cook your rice the night before. Fresh hot rice turns mushy in a sealed container. Day-old, slightly chilled rice actually holds up better and tastes just as good.
- Don’t skip the cornstarch in the marinade. It’s a small step but it’s what gives the chicken that glossy, restaurant-style coating once it hits the pan.
- Pickle your cucumbers while the chicken marinates. They only need 15 minutes to taste great, and it’s basically free extra flavor.
- Pack wet and dry ingredients separately if you can. Sauce touching rice for six hours in the fridge is how you end up with soggy rice.
How to Make It
- Combine the soy sauce, brown sugar, rice vinegar, garlic, ginger, and cornstarch in a bowl. Whisk until smooth.
- Cut the chicken thighs into bite-sized pieces and toss them in the marinade. Let sit for at least 20 minutes.
- While the chicken marinates, slice the cucumber thin and combine it with the pickling vinegar, sugar, and salt. Set aside.
- Cook your rice according to package instructions, or use a rice cooker if you have one.
- Heat the sesame oil in a large skillet over medium-high heat.
- Add the chicken (save the extra marinade) and cook for about 6 to 8 minutes, stirring occasionally, until browned and cooked through.
- Pour the reserved marinade into the pan and let it simmer for 2 to 3 minutes until it thickens into a glaze.
- Steam or microwave the edamame according to package instructions.
- Assemble your bento boxes: rice in one section, teriyaki chicken in another, edamame and carrots in a third, pickled cucumbers on the side.
- Top with sesame seeds and green onions.
- Let everything cool slightly before sealing the containers, so you don’t trap steam and make things soggy.
Substitutions and Variations
| Original | Swap |
|---|---|
| Chicken thighs | Tofu, cubed and pan-fried |
| White rice | Brown rice or cauliflower rice |
| Soy sauce | Coconut aminos (for gluten-free) |
| Brown sugar | Honey or maple syrup |
| Edamame | Steamed broccoli or snap peas |
| Carrots | Bell pepper strips |
Feeling ambitious? Swap the teriyaki for a spicy gochujang glaze and you’ve basically got a whole new lunch.
Make-Ahead Tips
This recipe was basically made for meal prep.
- Cook the chicken and rice up to 4 days ahead and store separately in the fridge.
- Prep the pickled cucumbers up to a week ahead. They actually get better with time.
- Assemble the full bento boxes the night before you plan to eat them, or the morning of.

Meal Pairings
- A cup of miso soup on the side turns this into a full restaurant-style meal.
- Fresh fruit like mandarin oranges or pineapple chunks add a nice sweet contrast.
- A small green tea or iced barley tea rounds it out nicely.
Leftovers and Storage
Store assembled bento boxes in the fridge for up to 4 days. Keep sauces or dressings in a small separate container if you’re adding anything extra.
To reheat, remove any raw or pickled components first, then microwave the rice and chicken for 60 to 90 seconds. Add the cold components back in after.
These don’t freeze well once assembled, but the cooked chicken alone freezes fine for up to 2 months.
FAQ
Can I make this vegetarian? Yes, swap the chicken for tofu or tempeh. Marinate and pan-fry it the same way.
What’s the best container for bento boxes? Anything with dividers works, but I like ones with a leak-proof seal for the sauce.
Can kids eat this? Absolutely, just dial back the ginger and garlic slightly if you’re packing it for little ones.
Why is my rice mushy? It’s almost always from packing it too hot or letting sauce sit directly on top of it for hours.
How far in advance can I prep these? Up to 4 days for the full assembled box, longer if you store components separately.
Wrapping Up
Bento boxes turned lunch into something I actually look forward to, and I hope this one does the same for you and yours.
