If using fresh corn, shuck the ears and cut the kernels from the cob. Set aside half of the kernels (about 1 1/2 cups). Place the remaining kernels in a food processor or blender and coarsely purée. If using frozen corn, ensure it is fully thawed and, if desired, purée half for added creaminess.

In a saucepan, heat the vegetable broth over low heat, keeping it hot and maintaining a gentle simmer throughout the cooking process.

In a large heavy-bottomed pot or Dutch oven, melt 2 tablespoons of butter with the olive oil over medium heat. Add the finely chopped onion and cook for 5 to 7 minutes, stirring regularly until softened and translucent. Avoid browning.
04 -
Stir in the minced garlic and chopped fresh thyme (or preferred fresh herbs), cooking for 1 minute until fragrant but not browned.

Add Arborio rice to the pot and stir continuously for 2 to 3 minutes until the grains are lightly toasted and become translucent around the edges.

Pour in the dry white wine, if using, and stir until fully absorbed and the alcohol has evaporated, about 1 to 2 minutes. If omitting wine, add an equivalent amount of broth.
07 -
Add one ladleful (about 1/2 cup) of hot broth to the rice, stirring constantly. Continue adding broth one ladleful at a time, stirring and allowing each addition to be absorbed before adding the next. Maintain a gentle simmer and continue for roughly 10 to 15 minutes.

Stir the corn purée into the risotto and mix well to evenly distribute. Continue to add broth as needed.
09 -
When the risotto is thickening but the rice is still slightly firm, add the reserved corn kernels and cook for 5 more minutes, continuing to stir and ladle in broth until the rice is just al dente.

Inspect the risotto for a creamy, flowing consistency and rice grains that are tender yet have a slight bite at the center.

Remove the pot from heat. Stir in the remaining 2 tablespoons of butter and the grated Parmesan cheese until fully melted and incorporated. If using, blend in heavy cream for added richness.

Taste, then season with salt and freshly ground black pepper as needed. Serve immediately, garnished with extra Parmesan cheese and fresh thyme if desired.
