What Makes This Soup Special
The charm of this soup lies in its simple but smartly chosen ingredients. Each one brings something different to the table—whether it’s sweetness, depth, freshness, or a bit of tang. Here’s why they matter:
-
Sweet Potatoes (12 large, peeled and diced): The backbone of this recipe. Roasting enhances their natural sweetness and gives the soup a rich, creamy base.
-
Olive Oil (1 tablespoon): Used for roasting, it helps the sweet potatoes caramelise nicely while adding a mild, nutty flavour.
-
Onion (1 medium, chopped): Provides a savoury depth that balances the sweetness of the potatoes. Once sautéed, it adds body and aroma to the soup.
-
Garlic (3 cloves, minced): Brings a sharp, earthy note that enhances the overall flavour. A short cook ensures it stays aromatic without becoming bitter.
-
Vegetable Broth (4 cups): Forms the liquid base and ties all the ingredients together into a smooth, cohesive soup.
-
Black Beans (1 can, drained and rinsed): Add texture, protein, and heartiness, making this a wholesome and filling meal.
-
Salt and Pepper (to taste): Basic seasoning that sharpens and balances all other flavours.
-
Lime (1, juiced, plus wedges for serving): Brightens up the soup with acidity and cuts through the richness of the potatoes.
-
Cilantro (2 tablespoons, chopped): Used as a garnish, it lends freshness and colour, rounding off the dish with a final layer of flavour.
Step-by-Step: Making Roasted Sweet Potato and Black Bean Soup
This soup is straightforward but benefits from taking each step carefully. Here’s how to bring it together:
Step 1: Roast the Sweet Potatoes
Preheat your oven to 400°F (200°C). Toss the diced sweet potatoes with olive oil and spread them evenly on a baking tray. Roast for 25–30 minutes, until they’re tender inside and golden around the edges. This roasting step is key—it brings out a caramelised sweetness that builds the base flavour of the soup.
Step 2: Prepare the Aromatic Base
While the sweet potatoes are roasting, heat a little oil in a large pot over medium heat. Add the chopped onion and sauté for about 5 minutes until translucent. Then stir in the minced garlic and cook for another minute, just until fragrant. These aromatics create the foundation of savoury flavour in the soup.
Step 3: Combine and Simmer
Once the sweet potatoes are roasted and slightly cooled, transfer them to the pot. Pour in the vegetable broth and stir well. Bring the mixture to a gentle simmer for a few minutes so the flavours begin to meld.
Step 4: Blend to Smoothness
Using an immersion blender, puree the mixture until smooth and creamy. If you’re using a countertop blender, do it carefully in batches (never overfill with hot liquid). Once blended, return everything to the pot if needed.
Step 5: Add the Black Beans
Stir the rinsed black beans into the blended soup. Let them warm through on low heat. The beans give the soup texture and make it more filling without overpowering the base flavour.
Step 6: Adjust and Brighten
Season with salt and pepper to taste. Finally, squeeze in fresh lime juice and stir well. This acidity balances the natural sweetness of the potatoes and keeps the soup from tasting heavy.
Step 7: Serve and Garnish
Ladle the hot soup into bowls. Top with fresh cilantro and serve with lime wedges on the side. The garnish adds freshness while giving your guests the option to adjust the brightness to their liking.
