Ingredients you will need
** This post contains tips and instructions to achieve the best possible results. The photo above is a great guide for when you are in the supermarket, but for full ingredient quantities and methods, please scroll down to the detailed recipe card below!
- Mushrooms. This recipe makes the most out of ordinary mushrooms, rather than those that are hard to find. Portobello, Swiss Brown or other common field mushrooms can be used alone, or with a mix of shiitake, enoki or oyster for different flavours and textures. You can read more about mushroom types here.
- Arborio rice or carnaroli are the best types of rice to use for risotto. These rice varieties are pale and stubby and release more starch than other long grain rice, which thickens the liquid and makes the sauce beautifully creamy.
- Risotto wine. A dry white wine like Chardonnay (unoaked) or Sav Blanc or Pinot Grigio are perfect for this recipe. Nothing too sweet, or the balance will be off. The alcohol will disappear during the cooking process, but if you avoid alcohol you can use extra stock instead. The final taste will be different, but still delicious.
- Stock. For a vegetarian risotto, use vegetable stock. But you can also use chicken stock if this is what you have on hand.
- Parmesan cheese helps to thicken and flavour the sauce. For this recipe, fresh grated cheese is best, rather than pre-packaged shredded cheese. This is because fresh cheese will melt properly into the sauce. Make sure you have extra for sprinkling over the top!
Step by step guide
If your cooker has a sauté function, set it to high heat and stir the olive oil, onion, and garlic together until soft. Add the mushrooms until browned. **If you don’t have a sauté function, this step can be done in a pan.
Once the mushrooms have browned, simply add all of the remaining ingredients into the slow or pressure cooker pot and cook according to the instructions below.
Carefully vent and remove the lid once the pressure has released. The liquid will be sitting on top, so stir until combined. The risotto will appear a little runny, but the rice will continue to soak it up within a couple of minutes.
At this point, it is important to taste the risotto and season it well with salt and pepper before serving. Serving suggestion: It is optional, but I highly recommend serving this risotto topped with additional fried mushrooms, shaved parmesan and chopped parsley.
Expert tips
- Slow cooker vs pressure cooker: I have tested this recipe several times in both pressure and slow cooker and the result is almost identical, whichever method you choose. Obviously, the main difference between the two is time. The pressure cooker takes around 14 minutes (plus time to build pressure) and the slow cooker takes a little over 2 hours on a high setting.
- Once the risotto is cooked, don’t leave it in the pot, or it will continue to cook and become mushy. It is best served immediately when it is ready.
- Want an extra serve of veggies? For mushroom and pea risotto, add 2 cups of frozen peas. You can also add a few handfuls of baby spinach leaves to the finished risotto and stir until wilted. Or, serve with some steamed asparagus or sautéed green beans.
- If your family prefer meat with their meal but you are short on time, feel free to stir through some shredded rotisserie chicken or bacon if you prefer!
- Use whichever stock you have on hand. For vegetarian risotto, use vegetable stock. Chicken stock also works.
- Storage: while risotto is best eaten when it is fresh, if you do have leftovers they will be fine in the fridge. Store risotto in an airtight container in the fridge for up to 3 days. The risotto will thicken due to the starch in the rice, but you can add a little more stock when re-heating.
- Avoid freezing risotto. The texture of rice can become mushy and break apart in the freezer and have a grainy feel. You are best to store it in the fridge and consume within a few days.
FAQs
Risotto can be reheated on the stovetop. Allow the risotto to return to room temperature for 30 minutes before adding it to a pot. As it will thicken in the fridge, add an extra ¼ cup of warmed stock per 1 cup of leftover risotto and stir over medium heat until the risotto has heated through. Or, reheat in the microwave with a splash of additional stock.
I recommend using a dry, white wine. Pinot Grigio or Sauvignon Blanc are perfect, or an unoaked (crisper and lighter) Chardonnay.

For Instant Pot, Pressure Cooker
- Set your pressure cooker to sauté/high temp and add the olive oil, onion and garlic. Cook until the onions have softened (1-2 minutes).
- Add the sliced mushrooms and cook until they have softened and browned slightly.
- Add all of the remaining ingredients into the cooker and secure the lid.

- Top with extra pan fried mushrooms (optional), chopped parsley, shavings of fresh parmesan cheese and an extra drizzle of olive oil. Serve immediately. Enjoy!
For slow cooker
- If your slow cooker has a sauté setting, follow the steps above to cook the onion, garlic and mushrooms. If not, gently sauté the onion, garlic and olive oil in a frying pan over medium heat until soft. Add the mushrooms and cook until soft and browned.
- Add all of the risotto ingredients to the slow cooker pot and set the slow cooker to ‘high’ heat for around 2 hours, 15 minutes. **Cooking times will vary due to different brands and types of cookers. Start to check the risotto at around 2 hours. The rice is ready when it has softened to al dente and the sauce has thickened slightly.
- The liquid will be sitting on top, so stir until combined. The risotto will appear a little runny, but the rice will continue to thicken as it sits.

Thank you so much for commenting! I’m so glad that you found the tips useful. It does make such an easy, “hands-off” dinner. Andrea 🙂
Amy Shields says
Hello!
Do you need to do anything to the chicken and bacon first? Or can I just put it in at the start with the rice and leave it too cook slowly in the slow cooker?
Thanks!
Andrea Geddes says
Hi Amy! If you decide to add chicken and bacon too, it is up to you. I would give the chicken a little sautée in a pan first and then add everything according to the instructions above. I hope that helps! Andrea.

Thanks Sarah! Yep, I totally get that! I usually have at least one baby clinging to my leg while I try to cook 😀 so the pressure cooker comes in so handy.
