Smoky Vegetarian Lentil Soup
Easy, Scrumptious, and Gluten-Free

Bowl of Smoky Vegetarian Lentil Soup #SoupSoFineSmoky Vegetarian Lentil Soup

Our vegetarian lentil soup for the slow cooker is easy, delicious, and nutritious. It starts with one pound of dried lentils, diced aromatics, fire-roasted tomatoes, and seasonings.

The prep time is a quick 15 minutes. But if chopping onions and garlic in the morning just isn't your thing, you can chop everything the night or two before. Just store them in the refrigerator in an airtight container or bag, and they'll be ready to use when you are.

While the lentils don't need to be pre-soaked, you do need to sort through them. You'll be looking for bits of field debris that might have slipped through during the harvesting/sorting process. Then you simply pour them into a colander or fine mesh sieve and rinse with cold, running water. After the water has drained off, they can be added to the slow cooker.

Why Lentils Are Good for You

Lentils are plant superstars, and here are plenty of reasons to add them to your diet. They are high in:

  • protein - 13 grams in 1/4 cup uncooked 
  • fiber - 15 grams per serving
  • complex carbohydrates
  • potassium. 

But they are also low in:

  • fat - 0.5 grams per serving
  • calories - 180 calories per serving

Plus, lentils are a good source of iron, which is so important for healthy oxygen-carrying red blood cells.
