Creamy mushroom risotto made in the Instant Pot recipe is a favorite quick and easy dinner. It’s packed with nutritious mushrooms, and works as a main course or as a side dish.
I love making this risotto because it is so quick and easy to make. Unlike a stovetop risotto recipe there’s no need to stand and stir while you gradually add stock. You just quickly saute the mushrooms and aromatics, add the other ingredients and set it to cook. Plus, it’s a one-pot meal, so you don’t need to use (and clean) multiple pots and pans.

What do you need?
Pressure cooker
I use an Instant Pot to make this recipe, but you can use any brand of electric pressure cooker with a saute function, or a multicooker with a pressure cook function.
Key ingredients and substitutions
- Risotto rice – this recipe uses arborio rice. You can substitute another type of risotto rice if that is what you have, however, you should check the amount of liquid required for another rice to ensure that the rice-water ratio is correct. Add a little more chicken stock or water if required.
- Mushrooms – you can use any type of mushrooms that you like, but I tend to use Portabello or brown mushrooms. I’d recommend staying away from button mushrooms as they can be rather tasteless and bland, and this is a dish where you want the flavor of the mushrooms to shine.
- Onion – you can use a yellow / brown onion or red onion if you prefer. If you have no fresh onions you could substitute onion flakes. Use approximately 3 tablespoons in place of a medium fresh onion.
- Garlic – this recipe uses freshly crushed garlic cloves. Alternatively, you can use crushed garlic from a jar – use one teaspoon per garlic clove.
- Stock – I usually use chicken stock to make this recipe, however you can substitute vegetable stock if you want to make a vegetarian mushroom risotto.
- Parmesan cheese – Freshly grated Parmesan cheese adds a lot of flavor to this recipe. You can also use Parmesan powder if you don’t have any fresh, but don’t skip it!
How to make mushroom risotto in the Instant Pot
- First saute the onions, garlic, mushrooms and celery to release the flavors from these aromatic ingredients.
- Add the rice to the pan, and stir to coat the rice grains with the liquid in the pan.
- Add the stock and deglaze the pan (note: this just means gently scraping the pan with a wooden spoon to release any cooking residues into the stock).
- Bring the stock to the boil, then cancel the Saute programme. This starts the rice cooking and will help the pressure cooker to come up to fully pressure more quickly once you start the pressure cooking programme.
- Close and lock the lid, with the valve set to ‘Sealing’. Then pressure cook on High for 5 minutes.
- Once the cook time is up, use the quick release option to open the Instant Pot immediately, so that the risotto doesn’t become over-cooked.
- Stir the Parmesan, lemon zest and butter through the risotto, and serve topped with parsley.
Serving ideas
You can serve this mushroom risotto as a side for a main dish of grilled chicken or fish. Here are some easy recipes you could serve it with:
Or, make it a main meal by adding a fresh green salad and some crusty garlic bread.
