Lentils are known as the “powerhouse of nutrition,” and it’s easy to see why. They are a good source of potassium, calcium, zinc, niacin and vitamin K, but are especially rich in dietary fiber, lean protein, folate, and iron. According to The Centers for Disease Control and Prevention, eating plenty of nutrient-dense foods like lentils can lessen your risk of many serious medical problems. This tiny nutritional giant fills you up — not out!

Here’s how to make Slow Cooker Lentil Soup:


  • 3 medium carrots, chopped (or 4 small or 2 large)
  • 2 celery stalks, chopped
  • 1 large yellow onion, chopped
  • 3 cloves garlic, chopped
  • 1 large clove shallot, chopped
  • 2 cups dry green lentils (rinsed)
  • 8 cups Vegetable stock
  • 1 14-ounce can diced tomatoes
  • 1 bay leaf
  • 1 teaspoon dried thyme
  • Add in 15 Minutes Before Cooking Time Ends:
  • 1 head of Swiss Chard, cleaned and cut into bite-size pieces
  • 1 1/2 teaspoons red wine vinegar
  • 2 teaspoons Kosher salt
  • 1 teaspoon fresh ground black pepper
  • 1 teaspoon ground cumin


  1. Place chopped carrots, celery, onion, garlic, and shallot into the crockpot along with lentils, vegetable stock, canned tomatoes, bay leaf and dried thyme.
  2. Cover with lid and set cooking time (4 Hours on HIGH OR 8 Hours on LOW).
  3. Next, prep your swiss chard into bite-size pieces (I usually cut it both lengthwise and crosswise to achieve this), put in a bowl or Ziploc bag and place in refrigerator for later.
  4. When cooking time is up, add swiss chard, red wine vinegar, Kosher salt, black pepper, and ground cumin.
  5. Place lid back on and let sit covered for fifteen additional minutes before serving. This freezes great and makes 8 huge (1.5 cup) servings. Excellent served with a crusty bread and side salad. Enjoy!

Tip: use a food processor to do the chopping.
