  8. Season with salt, pepper, and chopped parsley before serving.

Easy Variations

  • Make it vegetarian by using vegetable broth and skipping the sausage.
  • Add turkey kielbasa, smoked sausage, or leftover ham for extra protein.
  • Stir in chopped spinach or kale during the last 5 minutes of cooking.
  • Add cooked barley or brown rice for an even heartier meal.
  • Sprinkle each serving with grated Parmesan cheese.
Kid Chef Tip: Lentils do not need to be soaked like dried beans. Kids can help rinse the lentils, measure the broth, stir the soup, and add the vegetables while learning safe knife skills.

Storage Tips

  • Lentils continue absorbing liquid as they cool. Add a little extra broth when reheating leftovers.
  • This soup freezes well for up to 3 months.
  • Store leftovers in the refrigerator for up to 4 days.
