This lemony zucchini and potato soup is a win-win all around. A buttery leek and potato base gets a boost of green from mild-tasting zucchini, and two cans of cannellini beans provides extra staying power for satiety.

Zucchini, also known as a courgette, is a good source of micronutrients like vitamin A, C, folate and potassium, while the cannellini beans are powerhouses of fiber and potassium. Vitamin A is a strong antioxidant that can support eye health and play a role in reducing risk of Age-Related Macular Degeneration, while folate is a key nutrient required for producing red blood cells and reducing brain/spinal cord defects during pregnancy.

The zucchinis are also high in carotenoids and lutein, which are anti-carcinogenic compounds known for reducing risk of breast and prostate cancer. The cannelini beans combine with the potatoes and leeks for a buttery flavor, and act as an excellent source of fiber and potassium, both of which are essential for cardiovascular health and gut health.

If the fiber and potassium weren’t enough, these beans also contribute the highest percentage of protein content of all ingredients in this soup, providing ~8g per ½ cup serving. Finally, the fragrant, grassy flavor of dried herbes de Provence and zesty juice of fresh lemon, offers comforting but strong flavors to send your taste buds to heaven.
