Hearty cabbage gets sweet and tender after long cooking in this easy plant-based Slow Cooker soup. With savory flavors from carrot, onion, and tomato paste, this simple oil-free vegan recipe is deliciously satisfying. Make a big batch and freeze extras for healthy meals all winter.
To make the soup: Peel and dice the carrot and onion. Seed and dice the bell pepper. Core and roughly chop the cabbage into large bite-sized pieces. Drain and rinse the red kidney beans.
Combine the carrot, onion, bell pepper, cabbage, beans, dried thyme, tomato paste, garlic, bay leaf, pepper, vegetable bouillon, and water in a Slow Cooker. Put the lid on and set on High for 8 hours.
After 8 hours, remove the lid, season to taste, and serve.
