1.5 cups brown or green lentils β picked over and rinsed
2 bay leaves
1 tsp dried thyme
8 cups vegetable broth
1.5 tsp kosher salt
0.5 tsp black pepper β freshly ground
1 tbsp red wine vinegar
fresh parsley β chopped (for serving)
Instructions
Pick over the lentils to remove any debris, then rinse and drain.
Warm the olive oil in a large pot over medium heat. Add the onion, carrot, and celery with a pinch of salt and cook, stirring occasionally, until softened and lightly sweet, 8β10 minutes.
Add the garlic and cook until fragrant, 30β60 seconds.
Stir in the tomato paste and cook, stirring, until it darkens slightly and coats the vegetables, 1β2 minutes.
Pour in the crushed tomatoes and cook, stirring, 2β3 minutes to meld flavors.
Add the lentils, bay leaves, dried thyme, and vegetable broth. Bring to a boil, then reduce to a gentle simmer. Partially cover and cook, stirring occasionally, until the lentils are tender but still hold their shape, 25β35 minutes.
Season with the kosher salt and black pepper. If the soup seems too thick, add a splash of hot water; if too thin, simmer uncovered a few minutes to reduce.
Off the heat, stir in the red wine vinegar and remove the bay leaves. Taste and adjust seasoning with more salt, pepper, or vinegar as needed.
Ladle into bowls and top with fresh parsley (for serving). Serve hot.
