Lentils are inexpensive and versatile, an easy main meal or a side dish. Their earthy taste pairs well with many flavor profiles and kinds of vegetables. It's hard to run out of ways to cook lentils.

These tasty lentils are full of flavor and are slow-cooked with garlic, tomatoes, carrots, and celery, and then topped with shredded cheddar cheese. Using the slow cooker takes the guesswork out of cooking lentils and also fills your house with a delicious smell. Eat them as is, garnished with shredded cheese and herbs such as parsley, or maybe even a dollop of sour cream. Slow cooker lentils are also always great when paired with cooked white or brown rice.

You can adapt this recipe based on your own dietary concerns. For example, it's easily made vegetarian by using veggie stock instead of chicken; eliminate the cheddar cheese (or use a vegan substitute), and it's also a dairy-free meal.

Tip for Making Lentil Recipe

For this recipe, you'll want to make sure you're using regular lentils or green lentils. Red lentils will work, but they won't hold their texture and will release their starches into the dish very quickly.

How To Store and Freeze Slow Cooker Lentils

Feeling Adventurous? Try This:

Feel free to change the profile of this dish to suit your liking.

  • Add rosemary - Use more or less of one kind of dried herb, or change the herbs completely. Rosemary works especially well with lentils.
  • Add sweet potatoes - Add a diced potato if you like; sweet potatoes are especially good with lentils.
  • Use more spices - Use curry powder, turmeric, ginger, and/or garlic for a more Southeast Asian palette.
  • Make it cheesy - Add a Parmesan rind to the slow cooker to boost the flavor.
  • Add more veggies - Before serving, remove the lid and add some chopped spinach or kale to the slow cooker. Put the lid back on and let the greens gently wilt, and then serve.
