Pumpkin flesh and pumpkin seed oil are related, but they are not the same flavour. The vegetable brings sweetness and body; the oil brings roasted seed depth. In risotto, the rice and pumpkin cook as usual with stock and butter. The pan comes off the heat before the Styrian oil goes in — often together with the last of the cheese.
That one change is what keeps the aroma intact. It's the same finishing discipline behind any honest comfort dish; more background sits in Cooking with Pumpkin Seed Oil and Heat and Frying.
The diced pumpkin turns sweet and soft; the oil stays darker, more aromatic, less sugary. Guests who only know pumpkin-spice desserts often pause at the first spoonful. Then a short conversation opens — not about roasting, but about that final swirl, warm or cold, and why it's there at all.
Butter or olive oil melts in a wide pan over medium heat. The onion softens without colour, then the pumpkin cubes join it and begin to sweat. The rice follows, stirred until the grains turn glossy. Wine, if used, reduces down — and the kitchen already smells like autumn before the first ladle of stock lands.

Hot stock goes in gradually, with frequent stirring, until the rice turns creamy and just tender — about 18 to 20 minutes. Some cooks mash a few pumpkin cubes against the side of the pan for extra body; others leave pieces whole for bite. Keep the stock hot so the rice never cools mid-cook. The Styrian oil stays in the bottle for now — this heat is not its moment.
Serves four.

Off the heat now. Butter and Parmesan turn the rice glossy. Only then does the pumpkin seed oil fold in — dark streaks against the orange, nutty instead of sweet. A few extra drops in the bowl, toasted seeds on top. The colour against the risotto is part of the plate; Colour and Taste explains what a good bottle should look like. A Thermomix can handle the chopping or keep the stock warm — the oil still goes in only at the very end: Thermomix.
Risotto firms up in the fridge. Warm it again with a splash of stock until creamy, then stir in a fresh teaspoon of pumpkin seed oil off the heat. Never boil the leftover oil into the rice. Against a finish of only butter or olive oil, the Styrian swirl is darker and more seed-forward — see Pumpkin Seed Oil vs Olive Oil.
