In a food processor, combine the chickpeas, pumpkin puree, chopped sage leaves, minced garlic, tahini, lemon juice, olive oil, ground cumin, ground coriander (if using), ground cinnamon, salt, and pepper.
Blend the mixture until smooth and creamy, scraping down the sides of the processor bowl as needed. If the hummus seems too thick, you can add a bit more olive oil or a splash of water.
Taste the hummus and adjust the seasoning if needed, adding more salt, pepper, or lemon juice to your preference.
Once the hummus reaches your desired consistency and flavor, transfer it to a serving bowl.
Drizzle a little extra olive oil over the top of the hummus. You can create a swirl with the back of a spoon.
Garnish the hummus with a few whole sage leaves and toasted pumpkin seeds.
If desired, sprinkle a touch of smoked paprika or cinnamon for added flavor and color.
Serve the pumpkin hummus with your choice of dippers, such as pita bread, fresh vegetables, crackers, or tortilla chips.
