Equipment

  • slow cooker

Ingredients

  • 2 cups split red lentils Make sure these are split lentils. If not, you will need to almost double the cooking time.
  • 1 cup chopped onions I like a little bigger chunks in mine, but if you like smaller, use a fine dice.
  • 1 cup chopped celery
  • 1 ½ cup chopped carrots
  • 4 cups large dice potatoes I used a blend of small creamer potatoes and cut them into quarters.
  • 2 bay leaves
  • 1-2 teaspoons cajun seasoning this will depend on how spicy you like your food. With only 1 teaspoon, it just adds flavor, add in another 2 and you will get a little spice!
  • 1 tablespoon minced garlic
  • 6 cups vegetable broth
  • ½ teaspoon salt You may need more, it just depends on how salty the broth you use is.
  • 1 teaspoon ground black pepper

Instructions

  • Add all ingredients to your slow cooker. Set it to 4-6 hours on high, or 6-8 hours on low. The time will depend a lot on your slow cooker and how hot it cooks, but also the size of veggies, etc.
  • A trick I like to use for slow cooker cooking is to take the lid off the last hour and let the soup cook down a little.
  • Check the soup after your 4 hours on high, or 6 hours on low. See if the potatoes and lentils are tender.
  • Adjust seasoning as needed when it is finished at the end of cooking time.
  • That is it and you are done! I love to top mine with some thinly sliced green onions or even pepitas as shown in the photos. That crunch and flavor is really delicious.
  • Now, sit back and enjoy. You deserve it!
