In a large pot, heat olive oil over medium heat. Sauté onion and garlic until translucent, 3–4 minutes.
Add canned pumpkin, vegetable stock, nutmeg, and smoked paprika. Stir to combine and bring to a simmer.
Simmer for 10–12 minutes to let the flavors meld.
Use an immersion blender (or transfer in batches to a blender) to puree until smooth. Adjust seasoning with salt and pepper.
Serve warm with a swirl of Bellwether Crème Fraîche, toasted pumpkin seeds, and fresh sage leaves.
