Recipe Notes

Variations Ideas
  • Lentils – We normally use red or green lentils but you can try red lentils for a change.
  • Broth – Chicken or vegetable broth can be used interchangeably depending on preference.
  • Coconut milk – You can add coconut milk right before serving into the crock pot. Just make sure you do this at the end of cooking or it will curdle. Coconut milk adds a new layer of flavor and makes it creamy.
  • Kale – You can substitute kale for the spinach. I would cut the ribs off the kale first though.
  • Sausage – If you are not trying to make a vegetarian soup, add some cooked ground sausage to the soup. The combination is very hearty and delicious.
  • Spicy – For a hint of spice add in ½ teaspoon of red pepper flakes or cayenne pepper.
Recipe Tips
  • Programmable Crock Pot – I love the programmable slow cooker for this soup that you can set for certain times. It makes busy days less hectic.
  • Crock Pot Liners – I recommend using liners for the slow cooker to make clean up super easy. You can just toss and go.
  • Food Processor: Use a small food chopper or food processorย to quickly and easily chop the onions. Another time saving tip is to learn how to freeze onions.
  • Don’t Overcook the Spinach – It is important that you do not add this until right before serving.
  • Lemon juice adds so much flavor to this soup – Don’t even think about skipping this step. The lemon really enhances the flavor and fresh lemon is best.
  • Consistency – If the soup is too thick for your preference, add more broth to thin it out. You can also do this when reheating leftovers. To thicken the soup use a immersion blender to mash the lentils.

Frequently Asked Questions

Can I Use Canned Lentils?

Canned lentils will become too soft. We recommend using dried lentils for best texture.

How to Store Leftover Lentil Soup

Put the soup inside an airtight container in the fridge. This will be good up to 4 days.

Can I Freeze Lentil Soup?

Yes! You can use freezer bags or containers. I prefer bags because they freeze flat and take up very little room in the freezer. The soup can be frozen up to 3 months. To reheat, allow it to thaw overnight in the refrigerator. Then heat on the stove or microwave until heated through.
