Savory Sweet Potato Turnip Soup

I remember one particularly harsh winter when I was just starting out as a chef. The budget was tight, the walk-in was looking rather sparse, and inspiration felt miles away. That’s when I stumbled upon a lone sweet potato and a forlorn turnip lurking in the vegetable bin. Necessity, as they say, is the mother of invention, and a surprisingly delicious soup was born. It wasn’t fancy, but the warmth and subtle sweetness of that simple creation brought a much-needed spark of joy on a dreary day.

Recipe Overview

• Prep Time: 10 minutes
• Cook Time: 25 minutes
• Total Time: 35 minutes
• Servings: 2-4
• Dietary Type: Vegetarian

Ingredients

• 1 large sweet potato
• 1 small turnip
• 2 small white potatoes
• 1 medium onion, chopped
• 4 large garlic cloves, chopped finely
• 1 tablespoon vegetable oil (approx.)
• Chicken flavored broth (enough to just cover the veggies) – Vegetable broth may be used as a vegetarian substitute
• Salt and pepper to taste
• ½ cup milk – Use your preferred type of milk, e.g. dairy, soy, almond.

Equipment Needed

• Large pot
• Cutting board
• Knife
• Immersion blender (or regular blender)

Instructions

1. Begin by heating the vegetable oil in a large pot over medium heat.
2. Add the chopped onion and garlic to the pot. Sauté until they become translucent and fragrant. This usually takes about 5-7 minutes. Be careful not to burn the garlic, as it will turn bitter.
3. While the onion and garlic are sautéing, wash and peel (if desired) the sweet potato, turnip, and white potatoes. Dice them into roughly 1-inch cubes. Uniform sizes will ensure even cooking.
4. Add the cubed sweet potato, turnip, and white potatoes to the pot with the sautéed onion and garlic.
5. Pour in enough chicken flavored broth (or vegetable broth) to just cover the vegetables. You don’t want too much liquid, as this will dilute the flavor of the soup.
6. Season generously with salt and pepper. Remember that you can always add more seasoning later, but it’s difficult to take it away.
7. Bring the soup to a boil, then reduce the heat to low, cover the pot, and simmer for about 25 minutes, or until the vegetables are fork-tender. A fork should easily pierce through the largest pieces of potato and turnip.
8. Remove the pot from the heat. Using an immersion blender, carefully blend the soup until it is thick and creamy. If you don’t have an immersion blender, you can transfer the soup in batches to a regular blender, being very cautious of the hot liquid (remove the center piece of the lid and cover with a towel to allow steam to escape safely).
9. Stir in the milk and blend for a few more minutes to combine. This will add richness and smoothness to the soup.
10. Taste the soup and adjust the seasoning as needed. Add more salt, pepper, or even a pinch of red pepper flakes for a little heat.
11. Serve the soup immediately.

Expert Tips & Tricks

• For a richer flavor, roast the sweet potato, turnip, and white potatoes before adding them to the soup. Toss them with olive oil, salt, and pepper, and roast at 400°F (200°C) for 20-25 minutes, or until tender and slightly caramelized.
• If you don’t have chicken flavored broth or vegetable broth, you can use water and add a bouillon cube or a teaspoon of vegetable bouillon powder for flavor.
• To prevent the soup from scorching on the bottom of the pot, stir it occasionally while it is simmering.
• Add a bay leaf or a sprig of thyme to the soup while it simmers for extra flavor. Remember to remove it before blending.
• For a vegan version, ensure you use vegetable broth and a plant-based milk alternative such as almond or soy.

Serving & Storage Suggestions

This Savory Sweet Potato Turnip Soup is best served hot, garnished with a swirl of cream or a dollop of plain yogurt (if not vegan). A sprinkle of chopped fresh herbs, such as parsley or chives, can also add a pop of color and flavor. It pairs perfectly with a crusty piece of bread for dipping.

Leftover soup can be stored in an airtight container in the refrigerator for up to 3-4 days. It can also be frozen for longer storage (up to 2-3 months). Thaw the soup in the refrigerator overnight before reheating. Reheat the soup gently in a saucepan over medium heat, stirring occasionally, until heated through. If the soup becomes too thick after reheating, add a little more broth or milk to thin it out.
