  • 2 tbsp olive oil
  • 1 large yellow onion, roughly chopped
  • 4 cloves of garlic, smashed and peeled
  • 1/4 to 1/2 tsp crushed red pepper flakes
  • 34 sprigs of fresh thyme (or sub 1 tsp dried thyme or 1 tsp italian seasoning)
  • 28 oz can crushed tomatoes
  • 3/4 c red lentils
  • 5 c veggie broth (or a mix of broth and water)
  • 1/2 tsp salt
  • 1/2 tsp fresh cracked black pepper
  • 1/2 c vegan sour cream (or substitute homemade cashew cream, see notes) + more to serve
  • fresh parsley, optional


  1. Heat a large soup pot over medium with the olive oil. Saute the onions, garlic cloves, and red pepper flakes for 5 minutes, stirring occasionally.
  2. Add the thyme, tomatoes, red lentils, salt, pepper, and vegetable broth and/or water. Increase the heat to high until it boils.
  3. Stir well, cover, and reduce the heat to low. Cook for 15-18 minutes until the lentils are tender and starting to become mushy.
  4. Using an immersion blender or upright blender, you’re going to blend the soup with the vegan sour cream until smooth. If using an upright blender, you’ll most likely need to blend it in batches and may need to let it cool slightly. Carefully transfer the soup to the blender along with the sour cream and blend until smooth. If using an immersion blender, add the sour cream to the pot and carefully blend until smooth. Add more liquid to thin out the soup to your preference.
  5. Serve with chopped fresh parsley, a drizzle of vegan sour cream, and red pepper flakes. Store leftovers in a sealed container for up to 5 days.


to make cashew sour cream, soak 1/2 cup of raw cashews for 8 hours (or in boiling water for 20 minutes). Drain, rinse, and blend with 1/2 to 1 cup of water, a pinch of sea salt, and 1 tsp apple cider vinegar until smooth. Use in place of sour cream.
