Grass-Fed Beef and Lentil Soup
For kid appeal, just call it Hamburger Lentil Soup!


  • 1 pound ground beef, grass-fed if possible
  • 1 onion, chopped
  • 3 cloves garlic, minced
  • 5 carrots, chopped
  • 3 celery ribs, chopped
  • 14.5-ounce can diced tomatoes, with juice
  • 1 28-ounce can tomato puree or crushed tomatoes
  • 1 28-ounce can water
  • 2 14-ounce cans chicken broth or stock **see tip below
  • 2 cups dry lentils, green or brown
  • 1/2 teaspoon oregano
  • 1/2 teaspoon sugar
  • 1/2 tablespoon balsamic vinegar
  • 1 teaspoon salt (or to taste) and cracked pepper to taste
small bunch chopped kale or other dark, leafy greens, optional (remove and discard any tough stems)


  1. Brown beef and onion in large soup pot or dutch oven. Add garlic and saute another minute. Add carrots through oregano, bring to a simmer and cook 45-60 minutes or until lentils are just tender. Stir in sugar, vinegar, salt, pepper, and kale, if desired, during last 10 minutes of cooking time.
  2. Slow cooker option: Brown beef, onions, and garlic. Transfer to slow cooker and add remaining ingredients, except the kale, as directed above. Cover and cook on low heat 6-7 hours or on high 3-4 hours, or until lentils are just tender.  As slow cookers vary from model to model, check early so as not to overcook the lentils.  Add kale during the final 15 minutes.


  • I typically start with a quart of chicken stock, adding the amount the recipe calls for and reserving the extra to add to the leftovers. As the lentils sit, they continue to absorb liquid and extra broth or stock will ensure that your soup is as thick or thin as you like.
