Ingredients In This Recipe
You can download a printable version of this recipe below. It lists all the ingredients you need and gives clear, step-by-step instructions to help you make it.
Olive oil – or use a light flavored oil like vegetable oil.
Brown onions – these are roasted and give a luscious flavor to the soup.
Pumpkin – We prefer butternut squash because it has a natural sweetness. However, you can use another variety.
Sweet Potatoes – use sweet potato with orange flesh.
Carrots – the addition of carrots is a great way not only to sneak in extra vegetables but also helps to make a thicker and heartier soup.
Also, being an orange vegetable, it won’t change the color of the soup when pureed.
Garlic when roasted adds a nice subtle flavor to the soup. If you don’t like garlic, you can leave it out.
Water, vegetable, or chicken stock depending on your diet.
Milk powder – gives the soup a creaminess without thinning it down. It can be left out to make vegan or dairy-free, or a splash of plant-based milk such as soy milk, coconut milk, or nut milk.
Equipment

Step By Step Instructions
This recipe uses two different cooking methods roasting and stovetop cooking.
- Roasting is the first method. It will bring the sweetness out of the vegetables and helps add depth and flavor to the soup.
- Boiling is the next. Boiling will ensure that every vegetable is fully cooked and soft, which is essential if you what a velvety smooth soup.
Step 1 - Remove the skin and seeds from the pumpkin and cut them into 2-3 cm (1 inch) thick slices. Peel and cut the carrots into quarters lengthwise.
Place the pumpkin and carrots in a large bowl, drizzle over one tablespoon of olive oil, sprinkle on a little salt, and toss well.
Transfer the vegetables to a baking tray lined with baking paper.
Peel the sweet potato and slice it into a similar thickness as the pumpkin. Peel and quarter the onions.
Peel the garlic cloves and leave them whole.
Place these into a large bowl, and toss in one tablespoon of olive oil and a little salt.
Transfer to a second baking tray lined with baking paper and roast the vegetables for about 50 – 60 minutes in a preheated hot oven.
Step 2 - Transfer the roasted vegetables and juices into a large pot.
Tip: Don’t worry if the carrots are still a little firm at this stage. They will continue to cook in the next step.
Add two liters (2.11 quarts, 8 cups) of water (or stock) to the pot and bint to a boil over high heat. Cover with a lid, reduce the heat to low, and simmer for twenty minutes.
Step 3 - Remove from the heat, and add four tablespoons of milk powder (if using). Use a stick blender to puree the vegetables until smooth, and season with salt to taste.

What to eat Pumpkin soup with
Our family loves this pumpkin and sweet potato soup with our puff pastry sausage rolls. These bite-sized sausage rolls are mildly spicy and the perfect flavor match for this soup.

Variations
Stock
You can use store-bought or homemade vegetable broth or chicken stock instead of water for more flavor.
Bouillon cubes
You can also use bouillon cubes to make a quick stock. Mix the bouillon curbs in a jug with the water before making the soup.
You could also crumble the recommended quantity of cubes for 8 cups of water straight into the soup pot.
Extra Vegetables
If you wanted to add another vegetable to the soup you could add a zucchini. Peel the zucchini before adding it to the pot.
If the zucchini skin is left, the soup will end up looking a little green when pureed.
Soup too thick
This soup is very thick and this is how we like it however not everyone likes thick soup.
If you prefer a thinner soup, make the soup using half the amount of vegetables and this will still be enough to serve 8.
If you have already made the soup and find it too thick. Thin it down with more water or stock to get the consistency you like.
But be aware watering the soup down like this will increase its volume.
When adding more liquid to the soup, make sure to adjust the seasoning before you serve it.
Short on time skip the roasting
