Velvety Thanksgiving pumpkin soup with warm spices is a healthy, vegetarian, family-style starter. This festive, seasonal bowl adds fresh, comforting flavors to the holiday table.
Heat 2 tbsp olive oil in a large pot over medium heat until shimmering, then add chopped onions, carrots, and celery. Sauté for 6–8 minutes, stirring occasionally, until the onions are soft and translucent.
Add pumpkin puree to the pot, and stir thoroughly to incorporate with the sauteed aromatics.
Pour in the vegetable broth. Bring the mixture to a gentle simmer over medium-high heat, then reduce heat to low and cover the pot. Simmer for 15 minutes to meld the flavors.
Stir in salt, black pepper, ground cinnamon, ground nutmeg, and maple syrup. Simmer uncovered for another 5 minutes, adjusting heat to maintain a gentle bubble without boiling over.
Turn off the heat. Carefully blend the soup using an immersion blender directly in the pot (or in batches in a countertop blender), until velvety smooth. Taste and adjust seasoning as desired before serving.
