Instant Pot Vegetable Soup

Instant Pot Vegetable Soup combines carrots, celery, potatoes, onions, garlic, and fire-roasted tomatoes cooked under pressure with herbs like oregano and basil. The method builds flavor by sautéing aromatics before pressure cooking, resulting in a hearty soup with tender vegetables and a rich tomato base. This soup is a filling and comforting option, adaptable with additions like spinach or kale for extra greens.

Description

The Instant Pot Vegetable Soup begins by sautéing sliced onions and minced garlic with bay leaves, oregano, and basil to release their flavors. Deglazing with vegetable stock removes any browned bits, ensuring depth in the broth. The main vegetables—carrots, celery, and cubed russet potatoes—are layered beneath fire-roasted crushed tomatoes and vegetable stock before pressure cooking briefly for tender texture.

This approach yields a soup where the potatoes and carrots soften well but retain shape. The fire-roasted tomatoes lend a slightly smoky and layered flavor, balanced by the fresh herbs. Including spinach or kale at the end adds fresh leafy texture and brightness to the soup.

The method focuses on gentle seasoning and balancing acidity from the tomatoes. It allows variations in tomato choices or leafy greens to suit taste. The recipe results in a warm and satisfying vegetable soup suitable as a light meal or accompaniment.

Practical advice notes that tomatoes vary in sweetness and acidity, so tasting and adjusting seasoning is important. To prevent potatoes from discoloring, soaking them in cold water prior to cooking is suggested. The soup can be customized to preferences and the instructions accommodate easy preparation with an Instant Pot.
