This Slow Cooker Curried Lentil Soup only takes about 10 minutes to prep, then let the crock-pot do the rest of the work to make this delicious, healthier vegetarian comfort food.


  • 4 cloves garlic, peeled and minced
  • 2 large carrots, peeled and diced
  • 1 medium white onion, peeled and diced
  • 6 cups chicken or vegetable stock*
  • 1 1/2 cups uncooked green or brown lentils, rinsed and picked over
  • 1 tablespoon Madras curry powder**
  • 1 teaspoon garam masala
  • 1 teaspoon ground cumin
  • 2 bay leaves
  • 2 cups roughly-chopped baby spinach
  • 3 tablespoons lemon juice, plus extra lemon slices for serving
  • salt and pepper
  • chopped fresh cilantro leaves, for topping


  1. Add the garlic, carrots, onion, stock, lentils, curry powder, cumin, and bay leaves to the bowl of a 4-quart or 6-quart slow cooker, and stir to combine.
  2. Cook on high for 4-5 hours or on low for 6-8 hours, until the lentils are tender.
  3. Stir in the baby spinach and lemon juice until combined.
  4. Taste, and season with salt and pepper to taste.  (I used about 1 teaspoon salt and 1/2 teaspoon pepper, but the saltiness of the soup will vary based on your type of stock.)
  5. Serve warm, garnished with lots of chopped cilantro and extra lemon slices, if desired.


*If you’re making this soup vegetarian or vegan, go with vegetable stock.  ;)  Also, if you want to make this gluten-free, double-check and be sure that all of the labels on your ingredients are certified gluten-free.

**I highly recommend using Madras-style curry powder for this recipe.  It adds a little extra heat, which I love.  (I used this brand, which I recommend.)  Also, if you’re new to making curried dishes and aren’t familiar with these spices, feel free to wait and add them in at the very end, and just add a teaspoon or so at a time until it tastes good to you.
