23 Nourishing Vegan Leek Recipes: Soups, Casseroles, Pastas, and More

By Lisa Esile, MS,

Sometimes called the "gourmet onion" because of their delicate flavor, leeks become sweet and incredibly tender when cooked. In many recipes, they can be used interchangeably with onions, and we find them preferable to onions in recipes where the flavorings are subtle. Leeks perfectly complement mild-tasting ingredients such as potato, garlic, zucchini, and white beans, and they work equally well with more robust flavors. Here are some of our favorite leek recipes to enjoy this season, including nourishing leek soups, hearty casseroles, primo pastas, tasty toasts, and lots more. Try one today!

Tips

Washing leeks: Dirt gets caught between the fibrous leaves and is often hidden from sight. Be sure to peel back the leaves and rinse well. Check out our guide to leeks for more on how to wash, store, prep, and cook these large, cylindrical alliums.

Green tops: While most recipes call for the white part of leeks, feel free to use the green tops (cut thinly) in soups and stews.

Vegan Leek Soup Recipes

Note: The recipe only yields 6 cups; double the recipe if you want leftovers or are serving for a larger group. A commenter shares, “I love this soup! I’ve made it for company, and they loved it, too!”

A fan writes, “Comfort food that’s perfect for a chilly, damp day.”

Grilled Corn Succotash

Succotash is a popular American dish featuring fresh corn, lima beans, and the best of summer’s bounty. This recipe calls for leek and bell pepper, with edamame standing in for lima beans. The trick to getting excellent flavor on the grilled veggies is to brush them with lime juice before grilling. A fan writes, “Wow was this good!”
Millet Curry

Millet in Coconut Curry

Leeks cooked with garlic take on a delicate buttery flavor and perfectly pair with the mild taste of cooked millet in this kid-friendly, quick and easy curry, which is fragrant with fresh ginger. Dates and lime juice are key to the success of this recipe, adding a sweet and sour balance of flavors. (You can use lemon juice if you don’t have lime juice.)
