Is it already getting cooler where you are? It's supposed to be a rainy weekend here for us. The evenings are getting cooler, which means it's that time of the year when soups are always welcome. And, the kids are already talking about going to our winter menu of soup, salad, and bread.
Why make this soup?
- It's a simple recipe. You can roast the veggies ahead of time and leave the veggies in the fridge. Then, just make the soup 20 mins before dinner.
- The ingredients are simple and easy to find, sweet potato and rest are easy pantry staples.
- This is a very versatile recipe which means you can alter it to suit your own family's needs. Use or omit the butter, use milk instead of cream, etc.
- The process for this soup is very straightforward.
- Roast veggies - 40 mins (can be done 2 days ahead)
- Prepare soup - 20 mins
Ingredients and substitutes
- Sweet potatoes - I like using orange sweet potatoes, which give a pretty color to the soup. And yet, the other sweet potatoes work just as well.
- Onion - I prefer the Spanish red onion because they add sweetness as they cook into the soup.
- Garlic - A little goes a long way. So, add small fresh garlic. If you are like me, then a few roasted garlic is a treat.
- Thyme - Adds a nice flavor to sweet potato. If you don't want thyme, another great addition would be half a teaspoon of cumin powder.
- Dairy - You can use milk, half and half, or cream. In fact, you can even use almond or coconut milk for this recipe.
Sweet potato soup
- Oven - Preheat oven to 325°F/ 165°C/ Gas Mark 3. Line a baking tray with aluminum foil and spray with oil to prevent sticking.
Pro tip - you can also use parchment paper. Lining the tray makes for easy cleanup.
- Prep - Clean and cut the sweet potato in half lengthways. Place them on the baking tray. Drizzle with olive oil, and season with salt and pepper.
Pro tip - Use a sturdy chopping board with a sharp chef's knife and be careful as this is a tough vegetable to cut. - Roast - Roast them in the oven for about 40 to 60 mins or until soft and tender. Remove from the oven, transfer the potatoes to a bowl and cover with plastic wrap or aluminum foil. After 15 minutes, uncover the potatoes. They should be easy to peel.
Pro tip - The sweet potatoes can be roasted a few days ahead and kept in the fridge until ready to make soup.
- Saute - In a soup pot or stockpot - add the remaining olive oil. Sauté the garlic and onions until translucent, then add the bay leaves, thyme, and sweet potatoes.
- Simmer - Then, add stock and season with salt and pepper. Simmer on medium heat for 10 minutes.
- Milk - Lower the heat to a gentle simmer. Add the grated nutmeg and parmesan cheese. Then, Add cornstarch to the milk and add it to the soup. If necessary add more water to bring the soup to a soupy consistency.
Pro tip - once you add milk do not bring it to a high boil it can cause the milk to curdle. - Blend - Using a hand blender, blend the soup until smooth.
Pro tip - If you are using a stand blender, let the soup cool for 5 minutes, and be careful as the hot soup can cause serious burns. - Remove from heat. Serve in soup bowls with toasted croutons or bread. Top with a drizzle of cream or a dab of butter.
Pro tip - The soup gets thicker as it cools, so you may need to adjust consistency again before serving by adding a little more hot water.
Tips for Success
- Roasting veggies caramelize the sugars and bring out the natural sweetness in the vegetables.
- If possible, make your own homemade stock. This makes a huge difference to homemade soups.
- If you use ready-to-use store-bought stock make sure to under season your vegetables as commercial stocks have tons of salt added to them
- You don't always need butter or cream for every soup. Vegetables with high fiber like potato, sweet potato, pumpkin, and butternut squash, become very creamy when cooked and pulsed. This means you can eat them more often if you make them healthier. Right?
- Often, a dab of butter or cream on the top adds that touch of flavor you need in a soup. So, add just that ½ teaspoon of butter or 1 tablespoon of cream on the top as garnish.
- Yogurt and milk are great alternatives to full-fat cream. Having said that, both milk and yogurt can split when added to soups. So, add them warm and at the last minute. Then, turn the heat off. OR
- A teaspoon of cornstarch in every cup of milk will prevent the milk from splitting.
- While yogurt is a great low-fat addition to soups, it can add a bit of tang which may or may not work with all vegetables.
