Instant Pot Mushroom Risotto

You want something cozy and rich-without babysitting the stove for 40 minutes. That's where this Instant Pot mushroom risotto steps in - a creamy Italian rice dish made with Arborio rice and sautéed mushrooms, adapted for pressure cooking, using Arborio rice - a high-starch short-grain rice from northern Italy that helps create the dish's creamy texture.

Creamy, earthy, and made with very little stirring, it's a weeknight upgrade with barely any hands-on time.

Save for Later!

Traditional risotto means constant attention. Stirring.

Watching. Timing broth additions.

But with the pressure cooker, you can skip the hassle and still get soft, starchy rice and tender mushrooms in a silky broth. No guessing.

Just set it and let the pressure do the hard part.

Why This Risotto Is Easier Than the Traditional Method

Making risotto usually means standing over the pot for what feels like forever, often stirring continuously for 30-40 minutes. This version skips that part without cutting corners on flavor, using pressure cooking (about 6-8 minutes at high pressure) that traps steam and infuses the rice.

• You only stir at the end. That's when the starch releases and makes the rice creamy.
• Mushrooms soak up the flavor. They cook under pressure with the rice, so you don't need a separate pan.
• Consistent results every time. No more dry or undercooked risotto.

It gives you the same comfort and richness-without hovering over the pot, and pairs well with blended cocktails to enjoy this summer.

Save for Later!

• Arborio rice - This short-grain rice creates the creamy texture.
• Mushrooms - Cremini or button mushrooms work best. Slice them thick so they hold shape.
• Onion and garlic - Adds depth and aroma to the base.
• Vegetable or chicken broth - Needed to cook the rice evenly and give it flavor.
• Parmesan cheese - Stirred in at the end for richness.

A splash of white wine, a little butter, and black pepper round things out.

Great Add-Ons and Mix-Ins

Want to switch it up or make it heartier? Try these optional upgrades:

• Stir in baby spinach just before serving.
• Add cooked chicken or shredded rotisserie chicken for protein, about 1 to 2 cups (roughly 150-300 g) stirred in at the end.
• Use mixed mushrooms like shiitake or oyster for a deeper flavor, adding woodsy umami and a firmer bite.

This dish also works well as a base. Add lemon zest, thyme, or even a soft-boiled egg for extra richness.

Storage and Reheat Notes

Risotto tastes best fresh, but it stores surprisingly well.

• Fridge: Keep in an airtight container for up to 3 days.
• Reheat: Add a splash of broth or water before warming on the stove or in the microwave. Stir as it heats to bring back the creaminess.

Skip freezing. The rice texture won't hold up after thawing.

Questions You Might Have

Can I use regular rice?
No, regular long-grain rice won't give the same texture. Arborio is essential for creaminess; its high starch content releases during cooking to create the velvety risotto texture.

What if I don't have wine?
Skip it. Add a bit of lemon juice at the end for brightness instead, about 1 teaspoon per serving to brighten flavors without overpowering the mushrooms.

Is this dish vegetarian?
Use vegetable broth and Parmesan made without animal rennet to keep it vegetarian.

How do I know it's done?
The rice should be tender but not mushy, and the liquid should be thick and creamy. Stirring at the end brings it all together.

It's packed with flavor from sautéed mushrooms and Parmesan, and made faster thanks to pressure cooking - a hearty main that finishes well with easy dessert boards in 15 minutes and simple make-ahead sweets like freezer desserts you can prep ahead.
