This rich, creamy Red Lentil Soup is flavored with turmeric, smoked paprika and nutritional yeast and brightened with lemon and parsley. We're serving it to hungry runners at this year's Shamrock Run in Portland, Oregon!
Heat oil in a soup pot over medium heat. Add onion and celery and cook until beginning to soften, about 5 minutes. Add carrot and cook until soft, another 5 minutes, then add garlic, salt and spices, and cook until fragrant, about 1–2 minutes more.
Add nutritional yeast, lentils and water to the pot and bring to a simmer. Reduce heat to medium-low, cover and cook until the lentils are soft, about 30 minutes.
Working in batches, puree soup in a blender until smooth and creamy. Return pureed soup to the pot to keep warm. Add lemon juice and adjust consistency with additional water and salt, if needed.
