What You'll Need

  • 2 tbsp olive or vegetable oil
  • 2 stalks celery, chopped
  • 3 carrots, chopped small
  • 1 onion, diced
  • 4 cloves garlic, minced
  • 3 bay leaves (optional, but recommended)
  • 8 cups water or vegetable broth
  • 1 3/4 cups green lentils
  • 2 potatoes, chopped into bite-sized pieces
  • 1 bunch spinach, coarsely chopped 
  • 1 tsp salt
  • 3 tbsp red wine vinegar (optional)

How to Make It

First, in a large soup or stock pot, cook the celery, carrots, onion and garlic in the vegetable oil or olive oil until soft, about 10-12 minutes, over medium heat

Next, add the water or vegetable broth, bay leaves and lentils. Simmer over medium heat, covered, for about 30 minutes, stirring occasionally. 

Add the potatoes and cook for 10 more minutes, or until the potatoes are lightly tender, then add the spinach and cook for another minute or two, just until spinach is wilted, stirring occasionally.

Remove your soup from heat and add salt and red wine vinegar, stirring to combine. Taste, and adjust seasonings to taste. A bit more salt or some fresh ground pepper might be welcome, depending on your taste.

Be sure to fish out the bay leaves and remove them before serving.

Enjoy your homemade lentil, vegetable and spinach soup!
