01 - Preheat the oven to 400°F. Line two baking trays with parchment paper.
02 - Scoop seeds from the pumpkin into a bowl. Rinse thoroughly to remove pulp, then pat dry with a kitchen towel.
03 - Cut pumpkin into 3/4-inch wedges. Place on one prepared tray, drizzle with 2 tablespoons olive oil, and sprinkle with half the salt and pepper. Toss to coat evenly and arrange in a single layer.
04 - In a small bowl, combine cleaned seeds with remaining 1 tablespoon olive oil, smoked paprika, cumin, and the rest of the salt and pepper. Spread evenly on the second tray.
05 - Roast pumpkin wedges for 30 to 35 minutes, turning once halfway through, until golden and tender. Roast seeds for 12 to 15 minutes, stirring halfway, until crisp and golden.
06 - Serve roasted pumpkin wedges warm topped with crispy seeds. Garnish with chopped parsley and crumbled feta cheese if desired.
