Line a baking sheet with parchment paper or a silicone mat. Place the cubed squash on the baking sheet. Drizzle 1 tablespoon (15 mL) of olive oil over the squash and lightly toss.
Transfer the baking sheet to the oven and roast the squash for 30-35 minutes, tossing occasionally until it is tender and lightly browned.
Place the roasted squash in a food processor or high-speed blender. Add the roasted red peppers, ¼ cup (59 mL) olive oil, tahini, apple cider vinegar, lemon juice, garlic, salt, and paprika. Blend for about one minute until smooth and creamy. Transfer the hummus to a bowl, cover, and refrigerate for at least 30 minutes.
Garnish with the pepitas, parsley, and a drizzle of olive oil before serving.
