Slow Cooker Lentil and Corn Soup

I found this recipe at when I did a Google search for a slow cooker recipe to use my green lentils with that were in my cupboard. This slow cooker lentil and corn soup is soup-er tasty! The salt from the soy sauce gives it plenty of flavour and the sweetness of the corn is just divine. Try it, you’ll be hooked on this slow cooker lentil and corn soup too!

I recently decided to start posting easy beginner recipes for those embarking upon a whole food plant-based (wfpb) diet, as I am. My intent is not to create new recipes, or reinvent the wheel, but to show some of the best recipes already out there, with credit to original creators where credit is due. Anyway, I hope you enjoy my pick of the best wfpb bunch!

Servings: 8

Calories: 277kcal  



  • 2 medium onions, diced
  • 3 large celery stalks, diced
  • 3 large carrots, diced
  • 2 cups corn, frozen, or cut fresh from the cobb
  • 1 ½ cups green or brown lentils, rinsed and drained
  • 1 tbsp garlic powder
  • 2 tsp oregano
  • 1 tsp thyme
  • 3 tbsp soy sauce or tamari sauce
  • 3 bay leaves
  • 5 whole peppercorns
  • 9 cups vegetable broth, low sodium


  • Dice all your veggies, including onions, celery, carrots, and add them to the slow cooker pot.
  • Add your fresh cut or frozen corn.
  • Add your rinsed and drained lentils.
  • Add the rest of the ingredients. I personally didn’t bother with the peppercorns, and it still tasted fine.
  • You can stir that lot if you want to, but it’s not necessary.
  • Cover your ingredients with the slow cooker lid and cook on low for 8-10 hours or, if you want to cook it on high, do so for 4-5 hours.
  • I like to cook mine for 5 hours on high and it works a treat!
  • After cooking you should get rid of the bay leaves and peppercorns. You can make the soup thick and creamy using an immersion blender or leave it thin and chunky (which is my preference).
  • Keep in the fridge for up to 5 days or freeze for up to 3 months.
