Sweet Summer Corn Soup

This vibrant vegan sweet summer corn soup captures the essence of the season in a single bowl. Using fresh corn cobs to infuse the vegetable stock ensures a deep, savoury flavour that perfectly complements the natural sweetness of the kernels and creamy yellow potatoes. A hint of cayenne and smoky paprika adds warmth, creating a light yet satisfying dish that celebrates fresh, seasonal produce.

Ideal as a comforting lunch or an elegant starter, this plant-based soup uses soy milk and a partially puréed base to achieve a rich texture without the need for dairy. The addition of hand-charred red peppers provides a beautiful pop of colour and a sophisticated finish. Serve it with crusty bread for a wholesome, homemade meal that is both healthy and heart-warming.

  • Salt

  • 1/2 teaspoons paprika

  • Freshly ground black pepper

  • Big pinch of cayenne pepper

How to make Sweet Summer Corn Soup

Heat the stock in a large pot until it comes to a boil, then reduce it to a simmer. While it's heating, cut off the corn kernels from the cobs (cutting in a large salad bowl helps keep the kernels from flying all over). You should have about 1075ml /680 g of kernels. Place the 6 cobs in the stockpot, and simmer them covered, while you prepare the rest of the soup ingredients (for at least 20 minutes).

Heat the oil in a large skillet over medium heat. Sauté the onions for 3 minutes. Add the celery and thyme and sauté for another 4 minutes. Turn off the heat.

Remove the cobs from the stockpot with tongs, and place them on a plate to cool. Add the sautéed vegetables, potatoes, 1 teaspoon salt, paprika, 1/4 teaspoons pepper, cayenne, and coriander to the pot and simmer, covered, for 25 minutes, stirring occasionally.

Meanwhile, when the cooked cobs are cool enough to handle, take a sturdy knife and scrape down the sides of the cobs to collect the remainder of the kernels. This should yield about 240ml /150 g of kernel bits.

After the soup has cooked for 25 minutes, stir in the soymilk, corn kernels, and corn kernel bits. Simmer for 3 minutes. Remove 1 qt/960 ml of the soup and puree it in a blender or food processor until it's very smooth. Return the puree to the soup pot, and heat until it returns to a simmer, stirring frequently.

While the soup simmers, hold the whole pepper with metal tongs over an open flame on the stovetop. Turn it frequently until the skin is charred all the way around, about 5 minutes. Remove it from the heat and let cool. Using a clean dishcloth, rub off the charred skin. Remove the stem and seeds and cut the flesh into a fine dice. Set aside.

Turn off the heat for the soup and stir in the parsley. Season with salt and pepper. Ladle the soup into bowls and garnish each one with some of the red pepper. Serve immediately.
