  • 1 tbsp. Olive Oil
  • 1 lb. Italian Sausage casings removed and torn into pieces, or use bulk sausage
  • 1 Small Onion finely diced
  • 1 Carrot Diced
  • 1 Celery Rib Diced
  • 3-4 Garlic Cloves minced
  • ½ tsp. Dried Oregano
  • 12 oz. Dried Lentils picked through and rinsed
  • 4 cups Chicken Broth
  • 4 cups Water
  • 2 cups Diced Red Potatoes about 4 medium potatoes
  • 3-4 oz. Baby Spinach
  • Salt to taste
  • Fresh Ground Black Pepper to taste


  • Pick through the lentils and remove any foreign objects (such as tiny rocks). Rinse the lentils well and drain.
  • Remove the casing from the sausage and tear the sausage into small pieces.
  • Add the olive oil to a large pot over medium-high heat. Add the sausage and cook for 5 minutes to brown. Stir frequently and break it up using a wooden spoon or spatula.
  • When the sausage has browned, lower the heat to medium and add the onions, carrots and celery to the pot. Cook for 2-3 minutes, stirring frequently.
  • Add the garlic and oregano, stir to mix well and cook for 1-2 minutes, stirring frequently.
  • Add the lentils, chicken broth and water to the pot and stir. Raise the heat to high and bring the liquid to a boil, lower the heat to medium-low and cover. Cook the lentils for 15 minutes or so until they start to soften, stirring occasionally.
  • Add the potatoes to the pot. Raise the heat and bring the liquid back to a boil. As soon as it starts to boil, lower the heat to medium-low. Cook the soup for another 12-15 minutes, or until the potatoes and the lentils are tender.
  • Add the spinach to the soup and stir until it wilts.
  • Taste the Italian sausage lentil soup and add salt and pepper, to taste.


Pick through the lentils and remove any foreign objects (such as tiny rocks). Don’t skip this step, I frequently find small stones in my lentils.
