Authentic Mushroom Risotto in less than 20 minutes from start to finish. This Instant Pot Risotto recipe produces creamy, flavorful risotto every time. This is best served right out of the Instant Pot to experience the best silky texture of the risotto but leftovers throughout the week are also amazing, just not as “wet” as when first served. Reheating with a little extra water and pad of butter helps recreate the creamy original texture, however.
