Recipe Variations

  • Oil-free: Sauté using ¼ cup vegetable broth instead of oil to reduce fat.
  • Different spice profile: Swap or add spices such as smoked paprika, ginger, turmeric, or chili powder for a different flavor direction.

  • Fruit additions: Pear or apple can be added for a subtle fruity sweetness that complements the spices.
  • Greens: Stir in chopped spinach or kale after blending for color and nutrients.
  • Brighten it: Finish with a splash of apple cider vinegar or lemon juice to balance the sweetness.

How to Make Pumpkin and Sweet Potato Soup

Step 1: Finely dice one medium yellow onion, peel and dice two medium sweet potatoes, and mince three garlic cloves. Heat two tablespoons of olive oil in a large heavy-bottomed pot over medium heat. Add the onion and sauté 4–5 minutes until softened.

Step 2: Add the garlic, one teaspoon ground cumin, one teaspoon ground cinnamon, ½ teaspoon ground nutmeg, and ¼ teaspoon black pepper. Cook 1–2 minutes, stirring, until fragrant. Stir in diced sweet potatoes, 1 (15-ounce) can pumpkin purée, 4 cups vegetable broth, and ½ teaspoon salt. Bring to a boil, then reduce heat to a simmer, cover, and cook 20–25 minutes until the sweet potatoes are tender.

Step 3: Remove the pot from the heat. Use an immersion blender to puree until smooth, or transfer in batches to a countertop blender—leave the lid slightly ajar or vent between batches to allow steam to escape.

Step 4: Stir in 1 cup unsweetened plant-based milk and 2 tablespoons brown sugar or maple syrup to taste, if desired. Warm gently over low heat for 2–3 minutes, taste, and adjust salt and spices. Serve hot with a garnish of pumpkin seeds or chopped parsley.

FAQs

How do I make pumpkin purée from fresh pumpkin?

Halve a sugar or pie pumpkin, remove seeds, brush with a little oil, and roast cut-side down at 375°F (190°C) for about 35–55 minutes until fork-tender. Scoop out the flesh and mash or process into purée. Fresh purée may be slightly thinner than canned but works well in soup.

Can I make this soup in a slow cooker?

Yes. Complete the sauté steps, then transfer everything to a slow cooker with the sweet potatoes, pumpkin, and broth. Cook on LOW for 5–6 hours or HIGH for 3–4 hours, then blend and finish with plant-based milk and seasonings.

Pro Recipe Tips

  • Choose plain pumpkin purée: Avoid spiced or sweetened “pumpkin pie filling.”
  • Toast spices: Briefly toasting the ground spices in the pot releases essential oils and deepens the flavor.
  • Roast for extra depth: Roast diced sweet potato (or fresh pumpkin) for caramelized flavor before adding to the soup.
  • Adjust consistency: Add more broth for a thinner soup or more milk for creaminess; pulse the blender for chunkier texture.
  • Flavor improves with time: The soup often tastes better the next day after the flavors meld.

Serving Suggestions

Serve this sweet potato pumpkin soup as an appetizer, side, or main. It pairs well with a variety of toppings and sides:

  • Toppings: Fresh herbs such as thyme or parsley, cracked black pepper, roasted pumpkin seeds, croutons, a drizzle of coconut cream or vegan yogurt, red pepper flakes, or crispy shallots.
  • Bread: A crusty no-knead loaf, garlic bread, focaccia, jalapeño cornbread, or soft dinner rolls are excellent for dipping.
  • Salad: A simple leafy green salad balances the richness of the soup.

Storage Instructions

  • Fridge: Store in an airtight container for 4–5 days.
  • Freezer: Freeze in flat resealable bags, silicone trays, or freezer-safe containers for 3–4 months. Thaw overnight in the refrigerator before reheating.
  • Reheat: Gently reheat on the stovetop over medium-low heat or in the microwave in short intervals, stirring between heats.
