Tasty Lentil & Spinach Soup

A vegan one-pot soup that gets its character from fresh ginger and a finishing dash of apple cider vinegar. Brown lentils simmer in vegetable stock with celery and bay until tender, then a separately built spinach-tomato base goes in to brighten and round out the flavor.

Cooking the lentils with celery and ginger from the start (instead of just water or stock) layers in flavor as the lentils plump. The grated ginger especially gets time to bloom into the broth, giving the finished soup a warm, slightly spicy backbone that’s nothing like the dried-ginger flavor.

Building the spinach base separately is a smart move. Cooking the onion and garlic in oil first creates a savory aromatic foundation, then the tomatoes break down and the spinach wilts. Adding it all to the lentils at the end means the spinach stays bright green instead of cooking down into khaki.

The vinegar at the end is the move that takes this from good to memorable. A small splash of apple cider vinegar lifts the earthy lentil flavor and brightens the whole pot. Cilantro adds the herbal finish.

Two teaspoons sounds like a tiny amount of vinegar, but in a pot of lentils it makes a real difference. Don’t skip it.

Pro Tips

• Use brown or green lentils (not red). Red lentils break down completely and turn this soup into purée instead of a brothy soup with distinct lentils.
• Don’t salt the lentils until they’re soft. Salt added early can toughen the skins and lengthen cooking time.
• Peel the tomatoes if you want a smoother soup. Skins can roll up into chewy bits that throw the texture.
• Make a day ahead. Lentil soup tastes even better after a night in the fridge as the flavors meld.

Variations

• Add a teaspoon of ground cumin or smoked paprika to the lentil pot for warmer, more complex spice.
• Stir in a can of coconut milk at the end for a creamy, Thai-inspired version.
• Top with a swirl of Greek yogurt and a drizzle of olive oil for a richer presentation.
