Brown lentils simmer with tomatoes, carrots, celery, onion, oregano, and spinach for a simple, satisfying soup with plenty of texture. A Parmesan rind adds extra depth while keeping the dish wholesome and straightforward.
This Italian lentil and spinach soup starts with onion, celery, and carrots softened in olive oil, then layers in tomato paste, crushed tomatoes, oregano, and brown or green lentils. A Parmigiano Reggiano rind simmers in the pot for extra savory depth before being removed. The lentils cook until tender and the broth develops body; baby spinach is stirred in right at the end so it wilts without becoming overcooked. Finish with black pepper and a drizzle of olive oil if you like. It is a hearty, vegetable-rich one-pot soup with simple pantry ingredients.
