On cold winter days, especially after all the holiday feasting, this creamy lentil soup is the perfect foil for your hunger pangs. We developed this recipe in partnership with our friends and fellow Oregonians at Nancy's Yogurt.
Heat oil in a medium soup pot over medium heat. Add onion and saute until soft, about 5 minutes. Add garlic and saute until fragrant, 1-2 minutes. Add spices and saute until fragrant, 30-60 seconds.
Add tomatoes with juice, lentils, salt and water to the pot and bring to a simmer. Reduce heat to low and cook at a slow simmer until lentils are soft, about 30 minutes. Stir often.
Once lentils are soft, remove soup from heat and let cool for 5 minutes. While soup is cooling, whisk together yogurt and corn starch in a medium bowl.
Add about ½ cup of the soup liquid to the yogurt mixture and whisk until smooth. Gently add the yogurt mixture back into the warm soup, whisking until creamy throughout. Serve.
