Peruvian Quinoa Soup (Highland Vegetable Soup)

Inspired by the simple vegetable soups of the Peruvian highlands, this quinoa soup is light, savoury and gently sustaining rather than rich or heavy. Quinoa simmers directly in the vegetable stock, releasing just enough starch to give the broth a soft body while keeping its delicate texture. Carrot and potato make it warming and familiar, onion and garlic provide the savoury base, and fresh coriander lifts the finish with a clean herbal note. It is an easy vegetarian, gluten-free bowl for dinner, especially when you want something nourishing that still feels fresh.

Why this recipe works

  • One-pot method: The vegetables and quinoa cook together in the broth, keeping the process simple and the flavour cohesive.
  • Simple ingredients: Onion, garlic, carrot and potato provide a savoury base without overwhelming the delicate quinoa.
  • Good for leftovers: The soup keeps well and can be loosened with a little extra stock when reheated.

Authenticity notes

  • Andean-style ingredients: Quinoa and potato give the soup a clear highland character, reflecting the simple grain-and-vegetable broths common across Andean cooking.
  • Homestyle finish: The fresh coriander is added off the heat so it stays bright and herbal rather than becoming dull in the simmering broth.

Ingredient notes

  • Rinse the quinoa: Rinsing the quinoa before it goes into the pot helps remove any bitter coating and keeps the broth cleaner.
  • Choose the potato texture: Idaho potato gives a light, soft finish, while Yukon Gold makes the soup slightly creamier if used as a swap.

Texture tips

  • Keep the simmer gentle: A steady, gentle simmer lets the quinoa turn tender without clouding the broth or breaking down the vegetables too much.
  • Adjust after standing: Quinoa continues to absorb liquid as the soup rests, so add a little hot vegetable stock when reheating if the texture becomes too thick.

Make-ahead tips

  • Reheat gently: Warm the soup in a saucepan over moderate heat and add extra stock gradually until it returns to a spoonable consistency.
  • Freezer-friendly: Cool completely before freezing, then defrost overnight in the fridge and reheat until piping hot.

  1. Finely chop the onion and crush the garlic. Peel the carrots and potatoes, then cut them into small, even dice so they cook at the same rate.
  2. Heat the olive oil in a large pot over medium heat. Add the onion with the fine sea salt and cook for 6 to 8 minutes until softened but not browned, then stir in the garlic for 1 minute until fragrant.
  3. Add the carrots and potatoes and stir for 2 minutes to coat. Pour in the vegetable stock and bring to a gentle simmer.
  4. Rinse the quinoa in a sieve under cold water until the water runs clearer, then add it to the pot with the black pepper. Simmer gently for 18 to 22 minutes, stirring once or twice, until the quinoa is tender and the soup is lightly thickened.
  5. Taste and adjust seasoning with a little more fine sea salt or black pepper if needed. Take off the heat, stir through most of the fresh coriander, and ladle into bowls, scattering the rest on top.

Recipe notes

Tips

  • Keep the soup at a gentle simmer rather than a rapid boil so the quinoa stays delicate and the broth remains clear.
  • If the soup thickens too much as it stands, loosen it with a splash of hot vegetable stock and warm gently before serving.

Substitutions

  • Replace Fresh coriander with Fresh parsley for a milder, grassy finish.
  • Replace Idaho potato with Yukon Gold potato for a slightly creamier texture.

Storage

  • Refrigerate up to 3 days
  • Cool completely, then refrigerate in a sealed container for up to 3 days. Freeze for up to 2 months; defrost overnight in the fridge and reheat gently in a saucepan, adding a little vegetable stock if needed until piping hot.
