Servings: 2.5 quarts


  • Stock pot or large saucepan


  • 2 Tbsp olive oil (or butter)
  • 1 large onion - yellow, sweet, or white
  • 4 cloves garlic, peeled and diced
  • 2 large celery stalks, chopped
  • 2 large carrots, chopped
  • 2 cups green lentils, dry
  • 1 quart vegetable broth (4 cups, or more if a more brothy soup is desired)
  • 1/2 cup (up to 1 cup) water
  • 1 can (14 oz) crushed tomatoes
  • 2 bay leaves, fresh or dry
  • 1 tsp paprika (or smoked paprika)
  • 1/2 tsp coriander
  • 1/2 tsp cumin
  • 1/2 tsp sea salt
  • 1/2 tsp garlic powder
  • 1 bunch kale, variety of choice (about 7-11 leaves)
  • 1 lemon (to juice) OR 1 tsp red wine vinegar
  • salt and black pepper, finish to taste


  • Add olive oil or butter to the bottom of your stockpot or sauce pan and turn it on over medium-high heat.
  • Add chopped onions, celery, carrots and garlic along with a sprinkle of salt and pepper. Also add the bay leaves.
  • Saute until the onions become translucent, and the carrots and celery are just fork-tender (about 10 minutes). Stir occasionally. 
  • Rinse and sift the lentils under water in a colander.
  • Add all of the other called-for ingredients EXCEPT the kale and lemon (or vinegar) to the pot: the vegetable broth, lentils, canned tomatoes, and spices.
  • Bring to a boil and then reduce to a simmer.
  • Cover the pot with a lid and simmer for 25-40 minutes, until the lentils are cooked and softened to your desired texture. Stir occasionally.
  • De-stem the kale and roughly chop or tear the leaves into bite-size pieces.
  • Add the kale to the soup, stir, cover the pot again, and continue to cook for 5 minutes.
  • Remove the finished kale lentil soup from the heat before adding the juice from 1 lemon or 1 tsp red wine vinegar.
  • Taste and add more salt and pepper if desired.
  • Serve and enjoy!
  • Store leftovers in the refrigerator and enjoy within one week.
  • Freeze extras in freezer-safe containers for up to a year. Use within 6 months for best quality.


To adjust the consistency of the soup, feel free to add more water or broth. Or for a thicker, extra-creamy soup, you can blend a small portion (a cup or two) of the finished soup and add it back in - or give it a couple blitzs with an immersion blender.
