Slow Cooker Red Lentil Soup is so tasty and it came out so good! The flavors are diverse and rich and my husband loves it.

There is something I have to tell you about Ed. He puts saltine crackers in every soup or chowder that he sees.

No question or thought - he just adds the saltines. Thank goodness he loves this with his signature saltines (oh, well).

I love it too, sans the crackers, and so will you. 🙂

Vegetable broth adds flavorful liquid for the soup.
Carrots are sweet and cut into very small pieces for quick cooking.
Tomatoes add lots of tasty juices.
Tomato paste adds rich flavors for the base of this soup.
Onion is the best base for so many recipes. They cook up sweet and taste great.

Lemon juice just a little bit to add a tangy flavor.
Ground cumin is also unusual but gives more of a tasty kick.
Dried basil has a peppery taste and wonderful aroma.
Dried thyme is very earthy and a little bit sweet, with a slight mint taste.
Chili powder the king of spices for this soup and adds spicy heat.

💭 How do you freeze red lentil soup

IF FREEZING:
Let cool to room temperature. Package in rigid sided containers.
TO PREPARE AFTER FREEZING:
Remove from the freezer and put in the refrigerator overnight because it is a pretty solid mass and will take longer to defrost.
THE NIGHT OF SERVING:
Put all in a large saucepan and heat through. You can add more broth if you think it is too thick. Ready to serve.
