Earthy pearl barley infused with roasted parsnips, fresh thyme, and a silky cream finish. The Instant Pot cooks the barley to tender perfection while the parsnips caramelize slightly, creating a sophisticated European-style grain side that pairs beautifully with roasted meats or vegetarian mains.

Steps

Before you start

Peel and cut parsnips into 3/4-inch pieces (they will soften during cooking)
Measure pearl barley and vegetable broth—don't skip measuring for proper texture
Have fresh thyme ready or measure dried thyme before starting
Ensure your Instant Pot's trivet and lid are clean

1
Roast parsnips with oil and thyme
- Set your Instant Pot to the saute function on medium-high heat.
- Once hot (about 2 minutes), add 2 tbsp (30 ml) olive oil.
- Add the 1 lb (450 g) cut parsnip pieces and season with 1/2 tsp (3 g) of the salt and 1/8 tsp black pepper.
- Stir frequently and let them cook undisturbed for 1 minute between stirs so they develop light golden color on the cut edges.
- After 5-6 minutes of sauteing, when the parsnip pieces have taken on light color, add the 4 fresh thyme sprigs and stir once more.
- Press Cancel to turn off saute function.

Ready when: Parsnip pieces are light golden on the edges
Tip: Don't skip this step—the roasting develops deeper flavor than boiling alone. Stir often to prevent sticking.
2
Add barley and broth to Instant Pot
- Pour the 1.5 cups (300 g) pearl barley directly into the Instant Pot with the roasted parsnips.
- Stir gently to combine.
- Add the 3.5 cups (840 ml) vegetable broth and the remaining 1/4 tsp (2 g) salt.
- Scrape the bottom of the pot with a wooden spoon to release any browned bits (deglazing).
- Stir once more to combine all ingredients evenly.

Ready when: All ingredients are evenly combined and broth covers the barley
Tip: Deglazing adds residual flavor from the roasting. Don't overstir—the barley will cook more evenly with less agitation.
3
Pressure cook barley and parsnips
- Place the Instant Pot lid on securely and set the vent to 'Sealing.' Select High Pressure and set the timer for 20 minutes.
- The pot will take 3-4 minutes to come to pressure before counting down.
- Do not open or adjust the vent during cooking.

Ready when: Pot beeps when pressure cooking cycle completes
Tip: High pressure ensures the barley becomes creamy and tender. Don't use quick release—a natural release helps the texture.
4
Natural release pressure
- Once the cooking time is complete and the pot beeps, turn off the heat (it will stop automatically).
- Leave the Instant Pot untouched for 10 minutes to allow natural pressure release.
- You'll see the float valve (the pin on top of the lid) drop when all pressure has released.

Ready when: Float valve has fully dropped; no steam hisses when lid is gently pressed
Tip: Natural release is crucial for pearl barley—quick release can leave grains unevenly cooked.
5
Finish with cream and butter
- Carefully open the lid (tilt it away from you to avoid steam).
- Remove the thyme sprigs with a fork or tongs and discard.
- Switch the Instant Pot to the saute function on medium heat.
- While stirring gently, pour in the 1/2 cup (120 ml) cold heavy cream in a thin stream, then add the 1.5 tbsp (21 g) cold butter pieces.
- Stir continuously for 2 minutes as the cream and butter meld with the barley cooking liquid, creating a silky sauce.
- Season with the remaining 1/8 tsp black pepper and taste for salt, adding a pinch more if needed.
+ Show details− Hide details
Ready when: Cream and butter are fully incorporated; sauce coats the back of a spoon and is pale and silky
Tip: Add cold cream and butter to hot liquid slowly to avoid breaking the emulsion. If sauce breaks, whisk vigorously off heat.
6
Serve and garnish
- Press Cancel to turn off saute function.
- Spoon the barley and parsnips into a serving bowl or divide among four shallow bowls.
- Ladle a bit of the creamy sauce over each portion.
- If using Parmigiano-Reggiano, top each serving with 1/4 oz (8 g) grated cheese and a small pinch of fleur de sel or finishing salt, if desired.

Ready when: Dish is served hot and creamy
Tip: The barley will continue to absorb liquid if held; serve immediately for the best texture. Reheat gently with a splash of broth if made ahead.

Tips

Pearl barley has a naturally creamy texture when cooked; it releases starches that thicken the cooking liquid. Don't stir it after pressure cooking or you'll break down the grains.
The roasting step is non-negotiable—it deepens the parsnip flavor beyond simple boiling and gives the finished dish a richer, more sophisticated taste.
If your cream breaks (appears curdled), whisk in 1 tbsp cold water off the heat to stabilize it. This is rare if the heat is kept to medium and cold cream is added slowly.
For a lighter version, substitute half the cream with whole milk and add an extra 1/2 tbsp butter, though the dish will be less rich.

Make ahead

Barley and parsnips can be pressure-cooked up to 2 days ahead. Store the cooled mixture (before cream step) in an airtight container in the refrigerator. To finish, reheat in the Instant Pot on saute mode with 2 tbsp vegetable broth, then add cold cream and butter as directed.

Storage & reheating

Refrigerate leftovers in an airtight container for up to 3 days. To reheat, add 2–3 tbsp broth or water to a skillet over medium heat and warm gently, stirring often, until creamy (about 5 minutes). The barley absorbs liquid over time; adjust consistency with more broth if needed. Do not freeze (cream-based dishes don't freeze well).

Substitutions

fresh thyme sprigs → 1.5 tsp (3 g) dried thyme. Add dried thyme with the broth rather than at the beginning; the flavor is more concentrated. Use half the fresh amount.
heavy cream → 1/2 cup (120 ml) creme fraiche or sour cream. Stir in off the heat after sauteing to prevent curdling. The result will be slightly tangier.
vegetable broth → 3.5 cups (840 ml) chicken or beef broth. Use these broths for deeper, richer flavor. Ratios stay the same.
parsnips → Carrots (1 lb / 450 g, cut the same size) or a mix of parsnips and celery root (1/2 lb / 225 g each). Carrots cook slightly faster; check tenderness at 15 minutes if substituting alone. Celery root adds earthiness.
