Southwestern Corn and Potato Soup

This Southwestern corn and potato soup is a vibrant, dairy-free dish that brings a touch of sunshine to the table. Combining the natural sweetness of golden corn with earthy potatoes and a hint of jalapeño heat, it offers a wonderful balance of textures. The soup is naturally thickened by mashing the potatoes directly in the pan, creating a satisfying consistency without the need for heavy cream or flour. It is a brilliant option for those seeking a fresh yet comforting lunch that is packed with flavour.

Perfect for a quick midweek meal or a healthy weekend lunch, this soup is incredibly versatile and easy to prepare using store-cupboard staples. The addition of fresh lime juice and coriander provides a zesty lift that cuts through the starchiness of the potatoes. For the best results, serve it in deep bowls topped with creamy avocado cubes and crunchy tortilla crisps for a delicious contrast in every spoonful.

How to make Southwestern Corn and Potato Soup

Meanwhile, peel potatoes and cut into 1-inch pieces.

Add broth, water, and potatoes to onion mixture and cover pot, then bring to a boil over high heat.

Reduce heat and simmer, uncovered, stirring occasionally, until potatoes are very tender, 12 to 14 minutes.

Coarsely mash potatoes in pot with a potato masher. Stir in corn and simmer, uncovered, 3 minutes.

Stir in lime juice, coriander, and salt to taste.
