01 - Preheat oven to 400°F. Toss the diced pumpkin with ½ tablespoon olive oil, salt, and pepper. Spread on a baking sheet and roast for 20 minutes, turning once, until tender and golden.
02 - While pumpkin roasts, heat the remaining ½ tablespoon olive oil in a medium saucepan over medium heat. Add the chopped shallot and sage; sauté for 2–3 minutes until fragrant and translucent.
03 - Add the oats and stir to coat in the aromatic oil for 1 minute.
04 - Pour in the vegetable broth. Bring to a gentle simmer, stirring occasionally, and cook for 10–12 minutes until oats are creamy and most of the liquid is absorbed.
05 - Stir in the roasted pumpkin, Parmesan (if using), nutmeg, and adjust seasoning with salt and pepper.
06 - Divide between two bowls. Garnish with toasted pumpkin seeds and fried sage leaves if desired. Serve hot.
