Heat olive oil in a large saucepan over medium-low heat. Add chopped onions and cook until translucent and just beginning to brown.
Add risotto, and cook over medium-low heat just until the rice kernels take on a glossy sheen.
Add white wine and cook until absorbed. Slowly add heated broth, 1/2 cup at a time, stirring only occasionally, until liquid is absorbed and rice is al dente. This is a fairly slow process. You don’t want to rush it, stir it too much, or add too much liquid at one time. There should still be a little bit of liquid in the risotto when you are finished and it will look very creamy, even though there is no cream!
Gently stir in roasted pumpkin bites. Serve with a spinkling of parmesan and a drizzle of brown butter over each serving. Garnish with dried cranberries, (optional), snipped sage leaves, and more grated Parmesan.
If you would like to have some roasted pumpkin wedges to serve with your risotto, then cut a little bit of the pumpkin into wedges before you peel it. These can then be tossed with olive oil and salt and pepper and roasted along with the pumpkin pieces. Set aside for garnishing the plate.
