Instant Pot Butternut Squash Quinoa Risotto
Nutty quinoa stands in for arborio rice in this creamy, sage-scented "risotto" that cooks in one pot with just one minute under pressure. Sweet butternut squash melts into the grains, and Parmesan and butter stir in at the end for a silky finish, with no constant stirring needed.

Steps
Before you start
- Rinse the quinoa in a fine-mesh sieve under cold running water for at least 30 seconds, rubbing the grains with your hand. This removes the bitter saponin coating.
- Cut the squash into small ½-inch (1.25 cm) cubes so it turns tender in only 1 minute of pressure cooking. Larger pieces will stay firm.
- Use a 6-quart (5.7 L) Instant Pot. In an 8-quart model, keep the amounts the same and expect it to take a little longer to come to pressure.
- Plan for about 10 minutes for the pot to come to pressure, plus 10 minutes of natural release. The pressure cooking itself is only 1 minute.
Prep the vegetables
- Peel the butternut squash, cut it in half, scoop out the seeds, and cut the flesh into ½-inch (1.25 cm) cubes; you need about 3 cups (450 g).
- Finely dice the onion, mince the garlic, and chop the sage.
- Rinse the quinoa in a fine-mesh sieve under cold water for 30 seconds and let it drain.

Ready when: Squash cubes are roughly uniform and quinoa water runs clear.
Tip: Microwave a whole squash for 2 minutes before peeling to make the skin much easier to cut through.
Sauté the onion
- Press Sauté and set it to Normal/Medium.
- When the display reads Hot, add the olive oil and diced onion.
- Cook, stirring often, for 5 to 6 minutes.

Ready when: Onion is soft and translucent with no browning.
Toast quinoa and aromatics
- Add the garlic, 1 tbsp of the chopped sage, and the drained quinoa.
- Stir constantly for 2 minutes to toast the grains.

Ready when: Quinoa smells nutty, looks dry, and the garlic is fragrant but not browned.
Tip: Toasting adds depth and helps the grains stay separate and distinct rather than mushy.
Deglaze the pot
- Pour in the white wine.
- Scrape the bottom of the pot thoroughly with a wooden spoon, loosening every stuck bit.
- Let the wine bubble for about 1 minute until nearly evaporated.
- Press Cancel.

Ready when: The bottom of the pot is completely clean and smooth, and the wine smell is no longer sharp.
Tip: Any stuck bits left on the bottom can trigger the "Burn" warning, so don't skip the scraping.
Layer in squash and broth
- Pour in the broth and stir once to level the quinoa.
- Scatter the squash cubes on top and sprinkle with the salt and the nutmeg, if using.
- Do not stir again, so the squash stays on top and away from the bottom of the pot.

Ready when: Liquid just barely shows around the squash and quinoa.
Tip: Keep the liquid at exactly 2 cups plus the wine. Too little risks a Burn warning, and too much makes the dish soupy.
Pressure cook
- Lock the lid and set the valve to Sealing.
- Press Pressure Cook (High) and set the time to 1 minute.
- The pot will take about 10 minutes to come to pressure before the countdown begins.

Ready when: Display counts down from 1 minute and then beeps.
Natural release
- When the pot beeps, leave it alone for 10 minutes so the pressure drops on its own and the quinoa finishes steaming.
- Then carefully turn the valve to Venting to release any remaining steam.

Ready when: The float valve has dropped and the lid turns freely.
Tip: A quick release right away can make the quinoa foam and spit out of the valve, and leaves it wetter.
Stir until creamy
- Open the lid away from your face.
- Stir vigorously for 1 minute, pressing some of the squash against the side of the pot so it breaks down into the grains and makes a creamy base.
- The quinoa should look like loose, glossy risotto.

Ready when: Grains are tender with the tiny spiral "tails" visible, and about half the squash has melted into the mixture.
Tip: If it looks tight or pasty, stir in 2 to 4 tbsp (30 to 60 ml) of hot broth or water.
Finish with cheese and butter
- Add the butter, Parmesan, lemon juice, and remaining 1 tbsp chopped sage.
- Stir for 1 to 2 minutes until the butter and cheese melt completely.
- Season with black pepper, then taste and add salt, 1/8 tsp at a time, if needed.

Ready when: The risotto is creamy and glossy, with no visible streaks of cheese or butter.
Tip: The lemon juice brightens the sweetness of the squash, so don't leave it out.
Rest and serve
- Put the lid back on for 3 minutes with the pot off heat so the risotto thickens slightly.
- Stir once and spoon into warm bowls.
- Top with extra Parmesan and black pepper.

Ready when: The risotto holds a soft mound on a spoon and slowly spreads when plated.
Tip: Serve right away, since quinoa risotto firms up quickly as it cools.
Good to know
Tips
- Rinse the quinoa well. Skipping this leaves a soapy, bitter taste.
- Don't stir after adding the squash and broth. Leaving the squash on top keeps it from sinking to the bottom and scorching.
- Vigorous stirring after pressure cooking is what makes it creamy. Mash some squash for body.
- For extra flavor, brown 2 tbsp (28 g) of butter in a skillet with 8 whole sage leaves until crisp, and spoon over the bowls.
Make ahead
You can peel and cube the squash and dice the onion up to 2 days ahead and refrigerate them in separate airtight containers. Rinse the quinoa just before cooking.
Storage & reheating
Room temperature: up to 2 hours. Refrigerator: store in an airtight container for up to 4 days. Freezer: freeze in portions for up to 3 months and thaw overnight in the refrigerator. To reheat, warm in a saucepan or microwave with 2 to 4 tbsp (30 to 60 ml) of broth or water per serving, stirring often, until hot and creamy.
Substitutions
- dry white wine, such as Pinot Grigio → Additional broth plus 1 tsp white wine vinegar. Use ¼ cup (60 ml) broth and add the vinegar with the lemon juice at the end.
- Parmesan cheese → Pecorino Romano or nutritional yeast. Pecorino is saltier, so reduce the salt by ¼ tsp. Use 3 tbsp nutritional yeast with olive oil in place of butter for a dairy-free version.
- fresh sage leaves → Fresh thyme leaves (1½ tsp total). Thyme is milder and works well with the squash. Dried sage is stronger, so use ½ tsp in total.
- butternut squash → Peeled sweet potato or kabocha squash, cut ½-inch (1.25 cm) cubes. Same weight and same cook time. Pre-cut packaged squash also works.
