This hands-free baked butternut squash risotto turns Arborio rice, tender squash, garlic, shallot, and thyme into a creamy, comforting meal—without standing at the stove to stir. Finish it with white wine, butter, Parmesan, and nutmeg for a glossy, savory-sweet risotto ready in about an hour.
Preheat the oven to 350°F and position a rack in the center. Warm 2½ cups of vegetable stock in a medium saucepan over medium-high heat until it reaches a gentle simmer, then remove the pan from the heat.
Add the Arborio rice, diced butternut squash, shallot, garlic, and thyme to a Dutch oven or another large oven-safe pot with a tight-fitting lid. Pour the warm stock over the ingredients and stir to combine.
Cover the pot and transfer it to the oven. Bake for 40–45 minutes, checking for doneness around 35 minutes. The rice should be mostly tender with a slight bite at the center. A little loose stock in the pot is fine; it will be absorbed as you finish the risotto.
Carefully remove the lid. Add the white wine, butter, Parmesan, nutmeg, salt, and black pepper. Stir vigorously until the squash breaks down slightly and the risotto becomes creamy and glossy. If it is too thick, stir in additional vegetable stock a splash at a time until it reaches your preferred consistency. Taste and adjust the seasoning.
Spoon the risotto into bowls and top with extra grated Parmesan or chopped fresh herbs, if desired. Serve warm.
