Sweet potato soup is a cozy, bright bowl that feels like a hug on cool days. This version keeps things simple: roasted sweet potatoes, onion, a touch of ginger, and smooth vegetable broth. It’s low-fuss, easy to scale, and great for meal prep.

I often pair this soup with heartier mains or a warm slice of bread. If you like combining legumes with sweet root vegetables, try this brown lentil sweet potato curry for a different take on sweet potato dinners.

This recipe hits the sweet spot between comfort and speed. It works well in every season but really shines in fall and winter. You can roast the potatoes for deeper flavor or simmer them for a quicker finish. Both methods yield a silky bowl that’s naturally sweet, slightly savory, and very satisfying. If you want a heartier companion on the side, try this hearty potato and bean soup it pairs nicely with a light sweet potato soup starter.

Ingredients, swaps and a simple twist

Here’s what you’ll need and why each part matters. The base is sweet potato and broth. Aromatics like onion, garlic, and ginger bring balance. Coconut milk or plain dairy adds creaminess. I include rosemary or thyme for a subtle herbal note.

Diet-friendly swaps and choices

• To make it vegan, use coconut milk and vegetable broth (already vegan-friendly here).
• For lower fat, substitute light coconut milk or use 1/2 cup milk and 1/2 cup water.
• If you want more protein, serve with a spoonful of cooked lentils or try pairing with this lentil potato soup for a full meal.
• If you prefer less sweetness, pick a firmer sweet potato variety and add a splash more lemon.

A simple variation to try

Roast the sweet potato cubes tossed in a little olive oil and smoked paprika at 425°F (220°C) for 25–30 minutes. Roasting builds a caramelized edge that deepens the soup’s flavor.

How to cook this sweet potato soup

Below is a clear, stepwise approach for making this soup on the stovetop. You can roast the sweet potatoes first if you like a richer taste.

Step-by-step method

1. Heat oil in a large pot over medium heat. Add chopped onion and a pinch of salt. Cook 5–7 minutes until soft and translucent.
2. Add garlic and ginger. Cook 1–2 minutes until fragrant.
3. Stir in the sweet potato cubes and smoked paprika. Mix to coat.
4. Pour in vegetable broth, bring to a boil, then reduce heat. Simmer 20–25 minutes until sweet potatoes are very tender.
5. Remove from heat. Use an immersion blender to puree until smooth. Alternatively, blend in batches in a countertop blender.
6. Return to low heat, stir in coconut milk, and warm through. Adjust salt and pepper. Add lemon juice to brighten.
7. Serve topped with a spoonful of plain yogurt or coconut cream, seeds, and fresh herbs.

You can roast the sweet potatoes first for a deeper flavor, then proceed from step 3.

Step	Details
1	Sauté onion in oil until soft, about 5–7 minutes.
2	Add garlic and ginger; cook 1–2 minutes.
3	Add sweet potatoes and broth, simmer until tender (20–25 min).
4	Blend until smooth, stir in coconut milk, season, and serve.

Texture, timing and tools

• Use an immersion blender for quick, one-pot pureeing. A countertop blender works too; blend in batches and watch for steam.
• For chunkier soup, blend only half the pot and fold the rest back in.
• If the soup is too thick, stir in extra broth or water a little at a time until desired consistency.
• If too thin, simmer gently to reduce and concentrate flavor.

One extra tip: a splash of acid (lemon or lime) brightens the bowl right before serving.

Keeping and warming leftovers

Storing it well

Let the soup cool to room temperature within two hours. Transfer to airtight containers. Refrigerate for up to 4 days. For longer storage, freeze in meal-sized portions for up to 3 months.

Warming without losing taste

Reheat gently on the stovetop over low heat, stirring often. Add a splash of broth or water if it thickened in the fridge. If using a microwave, heat in short intervals and stir between rounds.

A recipe you’ll make again

This soup is reliable and flexible. It stores well and works for lunches or light dinners. Small swaps change the character, so you can tune it to your pantry and mood.
