This creamy roasted sweet potato soup with spinach and garlic is super easy to make, full of veggie goodness and delicious flavours. Made using a handful of vegetables this soup takes less than 10 minutes to cook!
This delicious roasted sweet potato soup with spinach is one of the easiest and quickest soup recipes I have ever made! The sweet potatoes, along with the garlic cloves, are baked before being added into the soup, which keeps cooking time super short. This soup cooks in less than 10 minutes!
The main reason for roasting the sweet potato is that none of its sweetness is lost. Roasted garlic also tastes sweet, which is important as it balances out the earthy flavour of the spinach.
Another advantage of baking the vegetables is that there is less chopping to do! Simply pop them in the oven for about 35 minutes, then scoop out the pulp and add into the soup.
The spinach is added into the soup towards the end of cooking for maximum flavour and colour.

How to prepare the sweet potato
You can either roast the sweet potatoes whole (especially if they are not very round) or cut them in half lengthways, as I have done, and roast cut side up. I wanted the sweet potato to caramelise on top for more flavour.
Top tip
You can roast the sweet potato and garlic ahead and once cooled refrigerate overnight until you are ready to make the recipe.
Roasted sweet potato soup ingredients
Not only is this recipe easy and simple to make it also requires very few ingredients. In addition to the sweet potato the soup also contains garlic, fresh spinach, onion and a little oil. Simply cook these ingredients briefly in vegetable stock, season to taste, puree and serve!
Step-by-step recipe instructions
There is very little peeling and chopping involved so preparation time is short.
1.Start by roasting the sweet potato along with the garlic (unpeeled). Place both on top of a baking sheet lined with parchment paper, brush the sweet potatoes with a little oil, and roast in a preheated oven at 200 C for 30-35 minutes or until the sweet potato is fully cooked. Remove from the oven, peel and make the soup (see below).
2. In a large pot heat up the oil, add the onion, roasted garlic, sweet potato, stir and fry for 3 minutes, stirring often.
3. Add the spinach, hot stock, pepper to taste, cover and bring to the boil then lower the heat down to a simmer and cook for 3 minutes.
4. Remove from the heat and puree until smooth. Adjust the seasoning as needed.
Serving suggestions
Enjoy your roasted sweet potato spinach soup with toasted sunflower/pumpkin seeds, a dollop of yogurt, scatter of fresh parsley, cilantro or chives, drizzle of balsamic vinegar and oil. Also delicious with easy homemade cheese breadsticks.

can you make the soup by boiling the potatoes?
Yes though the flavour may not be as intense. Also if you don't want to roast the garlic use a little less fresh garlic.
It is delicious but what is 1 hot vegetable stock
It's 1 litre of stock. The letter 'l' stands for 'litre'. If you need US customary measurements you'll find the link under the ingredients.
This was delicious! I wish i could post a picture. The roasted garlic was on point. I roasted my onion some too to get that caramel flavor going and ended up pouring everything into my vitamix. I added a dollop of Greek yogurt and some whole spinach leaves on top as a garnish and it looked so pretty! Thanks for the great recipe!
Glad you enjoyed the recipe, great idea to roast the onion too and I really like the extras! Thank you for your feedback:)

Thanks Kirsty! Yes, it was really delicious and the garlic taste was subtle I guess because it had been roasted...
