In a large saucepan or frypan, heat the butter and oil together.
Sauté the onion and garlic until softened.
Add the rice, stirring to coat it evenly in the butter and oil mixture.
Cook for about a minute.
Stir in the pumpkin and mushrooms, then pour in 1 cup of the hot stock.
Simmer gently, stirring occasionally, until the liquid is almost fully absorbed.
Gradually add the remaining stock, one cup at a time, allowing it to absorb before adding more.
Stir frequently but you don’t need to hover over the pot if using non-stick.
This process will take around 20 minutes until the rice is tender.
Once done, mix in the Parmesan cheese, season with salt and pepper, and sprinkle in the parsley.
The cheese will make the risotto creamy and slightly sticky.
