Instant Pot Quinoa Soup w/ Vegetables

Instant Pot Quinoa Soup with Vegetables features a blend of vegetables and quinoa simmered in a flavorful tomato and vegetable broth base. The key ingredients — onion, carrots, celery, and zucchini — provide a sturdy texture chunkiness balanced by tender quinoa and spinach added at the end for freshness. The seasonings of oregano, garlic powder, and chili powder complement the gentle acidity of tomato sauce, creating a well-rounded broth. When prepared in an Instant Pot, this soup cooks rapidly under pressure, preserving the bright flavors and achieving tender vegetables.

The stovetop method gently simmers the ingredients, thickening the soup as the quinoa cooks and absorbs liquid. The resulting texture varies slightly between methods but remains hearty and comforting. This soup makes a wholesome option as a light meal or starter, offering vegetables and plant-based protein from quinoa in each serving.

To keep the soup from over-thickening as it cools and the quinoa absorbs more broth, add extra vegetable stock as needed when reheating. The recipe notes also recommend keeping the diced vegetables small except for zucchini to maintain a pleasing bite without becoming too soft. For pressure cooking, ensuring the Instant Pot lid is properly sealed and performing a quick release prevents overcooked squash and limp greens.
