Lentils are inexpensive, versatile, and they make for an easy main meal or a side dish. With their earthy taste, they pair well with lots of different 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.

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.


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

  • Use more or less of one kind of dried herb, or change the herbs completely. Rosemary works especially well with lentils.
  • Add a diced potato if you like; sweet potatoes are especially good with lentils.
  • Use curry powder, turmeric, ginger, and/or garlic for a more Southeast Asian palette.
  • Add a Parmesan rind to the slow cooker to boost the flavor.
  • 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.

How to Store and Freeze Slow Cooker Lentils

These cooked lentils should keep in the refrigerator for up to 5 days in an airtight container. For longer storage, this dish will freeze well—up to six months—in an air-tight container. Defrost in the microwave, in the refrigerator, or right on the stovetop.
