Preheat your oven to 375° F. In a large glass measuring cup, whisk together one cup of vegetable broth with the pumpkin purée until smooth, then set aside.
Heat the olive oil in a large heavy-bottomed oven-safe pot or Dutch oven over medium-high heat until shimmering. Add the finely chopped shallot and sauté for about one minute until fragrant; then add in the grated garlic and cook for an additional 30 seconds before seasoning with salt and pepper.
Pour in the dry white grape juice, allowing it to deglaze the pot by scraping any brown bits from the bottom which adds depth of flavor. Next, combine the pumpkin broth mixture with the remaining three cups of vegetable broth along with fresh herbs, spices, salt, and pepper; stir well before covering with a lid.
Once boiling, stir in the arborio brown rice thoroughly before placing the lid back on top of your pot. Remove from heat and place it on the middle rack of your preheated oven; let it bake undisturbed for about 60-70 minutes or until all liquid is absorbed, and rice is tender.
After baking, carefully remove the pot from the oven; stir in four ounces of goat cheese vigorously for about two minutes until creamy consistency is achieved. If you find that your risotto seems dry at this point, feel free to add more vegetable broth or water until you reach desired creaminess; season generously with salt and freshly cracked black pepper.
Spoon out portions of your creamy risotto into bowls or plates then garnish each serving generously with extra crumbled goat cheese, dried cranberries, pumpkin seeds, along with more chopped sage and rosemary for an added pop of freshness!
