Sauté Veggies: In a large pot, sauté the diced onion and celery until the onion softens. Add a little water or broth to prevent sticking.
Add Garlic & Simmer: Stir in garlic and cook for another minute. Then add diced potatoes, carrots, and vegetable broth. Bring to a boil, reduce heat, and simmer for about 15 minutes until vegetables are tender.
Blend the Soup: Add soy milk, nutritional yeast, paprika, garlic powder, onion powder, salt, and pepper. Blend using an immersion blender (or regular blender in batches) until smooth.
Add Broccoli & Lemon: Stir in steamed broccoli and lemon juice. Simmer for a few more minutes until heated through.
Serve & Enjoy: Ladle into bowls and enjoy the creamy comfort of this delicious soup!
