Steps

Before you start

Measure all ingredients before starting
Have the Instant Pot trivet or steamer basket ready
Snap peas can be prepped up to 4 hours ahead and chilled

1
Add barley and broth
- Pour the vegetable broth into the Instant Pot inner pot.
- Add the pearl barley and stir well to combine.
- Do not layer the barley; distribute it evenly in the liquid to ensure even cooking.

Tip: Even distribution prevents sticking and ensures consistent texture throughout.
2
Seal and pressure cook
- Close the Instant Pot lid and set the valve to 'sealing.' Cook on high pressure for 15 minutes.
+ Show details− Hide details
Tip: Use high pressure for faster cooking; the barley should be tender but not mushy when done.
3
Natural release and vent
- When cooking time ends, let the pot sit undisturbed for 10 minutes for natural pressure release.
- Then carefully move the valve to 'venting' to release any remaining steam.
- Open the lid away from your face.

Ready when: Pressure indicator drops and steam stops releasing
Tip: Natural release prevents the barley from breaking apart; don't rush to vent.
4
Make miso butter mixture
- In a small bowl, whisk together the miso paste and ¼ cup (60 ml) water until smooth and fully dissolved.
- Set aside.

Ready when: Miso is completely dissolved with no lumps
Tip: Dissolving miso in water first prevents lumps and ensures even distribution.
5
Stir in miso mixture
- Pour the miso-water mixture into the cooked barley and stir gently but thoroughly for about 30 seconds to combine evenly.
- Add the butter pieces and stir until fully melted and incorporated.
+ Show details− Hide details
Ready when: Barley is coated with a creamy, tan-colored sauce and butter is fully melted
Tip: Gentle stirring prevents breaking the barley grains; the residual heat will melt the butter completely.
6
Add corn and snap peas
- Fold in the corn kernels and snap peas, along with the white and light green parts of the green onions.
- Stir gently to distribute.
- Let sit for 2 minutes off heat to slightly warm the vegetables and soften the snap peas slightly.
+ Show details− Hide details
Ready when: Snap peas are still slightly crisp but warmed through, corn is heated through
Tip: Don't overcook the snap peas; they should retain a gentle crunch. If using frozen corn, thaw it completely first for best texture.
7
Season and serve
- Taste the dish and season with kosher salt and black pepper as needed.
- Remember the miso is already salty, so add seasonings gradually.
- Transfer to a serving bowl or individual plates.
- Garnish with the reserved dark green onion tops and sesame seeds if using.

Tip: Taste before adding salt since miso is quite salty; start with just a pinch of additional salt.

Tips

Toast sesame seeds in a dry skillet for 2–3 minutes over medium heat before garnishing to deepen their nutty flavor.
For a heartier side, add 2 ounces (60 g) of diced shiitake or cremini mushrooms in step 5 along with the corn and snap peas.
Miso paste contains live enzymes; don't boil it directly in the broth. Dissolving it in cool water first and adding after pressure cooking preserves its probiotic benefits.
If your snap peas are very large, halve them lengthwise for better texture distribution and easier eating.

Make ahead

Barley can be cooked and cooled up to 2 days ahead. Store in an airtight container in the refrigerator. To finish: reheat gently in the Instant Pot on sauté mode with a splash of broth, then add miso butter mixture, vegetables, and seasonings as in the final steps.

Storage & reheating

Refrigerator: Cover and store for up to 3 days. Reheat gently on the stovetop over medium-low heat with a splash of broth, stirring occasionally, until warmed through (about 5 minutes). Freezer: Not recommended, as the texture of the snap peas and barley soften significantly upon thawing. Consume fresh for best results.

Substitutions

low-sodium vegetable broth → chicken or dashi broth. Chicken broth adds richness; dashi deepens the Japanese flavor profile with its umami depth.
pearl barley → farro or short-grain brown rice. Farro has a nuttier flavor and firmer texture; brown rice will need 20 minutes cooking time instead of 15.
fresh snap peas → sugar snap peas, edamame, or asparagus cut into 1-inch pieces. Snap peas provide sweetness and crunch; edamame adds protein; asparagus offers earthiness.
white or yellow miso paste → red miso paste. Red miso is saltier and more robust; use 1.5 tablespoons (22 g) for a less intense but still rich flavor.
