Ingredients
Vegetables and Aromatics
- 5 cups (345 grams) Leeks, sliced thin (about two large leeks)
- 8 cups (440 grams) Green or Savoy Cabbage, cut into bite-size pieces or thinly sliced
- 2 cups (285 grams) Russet or Yellow Finn Potatoes, skins on, cut into small cubes (about two small potatoes)
- 4 fat cloves of Garlic, minced (add up to 6 cloves for more garlic flavor)
Liquids and Fats
- 4 tablespoons Unsalted Butter (or olive oil)
- 8 cups (1.7 kilograms) Low sodium Vegetable Broth
Beans and Herbs
- 1 3/4 cups (425 grams) Cooked Cannellini Beans, drained and rinsed
- 4-5 Thyme Sprigs, tied
Seasonings and Garnish
- 1/2 teaspoon Fine Sea Salt (adjust to taste, reduce to 1/4 tsp if using plant butter)
- Squeeze of Lemon, to taste
- Fresh Ground Pepper, to taste
- Shaved Parmesan Cheese, for garnish (optional)
Instructions
- Sauté Leeks: In a large 4-quart Dutch oven or stockpot, heat 4 tablespoons unsalted butter (or olive oil) over medium-low heat until shimmering. Add sliced leeks and cook, stirring frequently, for about 10 minutes until they are soft with a bit of golden color. Be careful to watch closely to avoid burning.
- Cook Cabbage: Add the chopped cabbage to the leeks in the pot. Continue cooking on medium-low, stirring occasionally, for about 9-10 minutes until the cabbage wilts and reduces in volume.
- Add Garlic, Broth, Potatoes, and Thyme: Stir in minced garlic and 1/2 teaspoon fine sea salt. Pour in 8 cups of low sodium vegetable broth, add cubed potatoes and the tied thyme sprigs. Bring the mixture to a simmer.
- Simmer Soup: Reduce heat to maintain a low simmer and cook for about 20 minutes until potatoes are fork-tender. If desired, simmer up to 40 minutes for creamier, softer potatoes that melt into the soup for a richer texture.
- Finish Soup: Remove and discard the thyme sprigs. Stir in the drained cannellini beans and a good squeeze of lemon juice to brighten the flavor. Warm through for about 5 minutes. Taste and adjust seasoning with additional salt and freshly ground black pepper as needed.
- Serve and Garnish: Ladle the soup into bowls and garnish with shaved Parmesan cheese and fresh thyme leaves if desired. Serve hot.
- Storage: Store leftover soup in a lidded container in the refrigerator for up to three days. The soup is freezer-friendly; freeze in portions and thaw overnight in the fridge before gently reheating on the stovetop.
Notes
- You can substitute olive oil for the unsalted butter for a dairy-free version.
- Using low sodium vegetable broth allows better control of salt level in the soup.
- Potato cooking times vary; adjust simmer time for preferred texture—from slightly firm to creamy-melted.
- Add up to 6 garlic cloves for a stronger garlic flavor.
- Shaved Parmesan topping is optional and adds a nice savory finish.
