Creamy Potato Leek Soup gets all of its silky texture from a can of full-fat coconut milk instead of heavy cream, so it is completely dairy-free. Tender Yukon golds and slowly sautéed leeks blend into a soup that still tastes like it is loaded with cream. 40 minutes, one pot, and it freezes beautifully.
Prepare leeks by thinly cutting and cleaning thoroughly.
2-3 large leeks
Peel potatoes and cut into 1-inch cubes.
2 pounds Yukon gold potatoes
Add olive oil and leeks to a large pot or Dutch oven over medium heat. Sauté leeks for 8-10 minutes or until they become soft and tender. Add crushed garlic and continue sautéing for 1 minute.
3 tablespoons olive oil, 4 cloves garlic
Pour vegetable broth into the post, making sure to scrape the bottom to loosen up any loose bits.
6 cups vegetable broth
Add potatoes, dried herbs, milk, and salt. Bring contents to a boil.
½ teaspoon thyme, ½ teaspoon tarragon, 1 ¼ cup coconut milk, 1 ½ - 2 tsp. salt
Bring contents to a boil. Reduce heat to medium and cover pot with a lid. Cook for 12-15 minutes, or until potatoes are tender.
Stir in lemon juice and add additional salt, to taste. Serve soup with a toasted baguette, croutons, or crackers and enjoy!
2 tablespoons lemon juice
Notes
Cutting: Leeks and potatoes in similar pieces means they finish cooking at the same time.
Leeks: Eight to ten minutes feels long, but that slow cook is where all the sweetness comes from. Rushing it leaves the soup thin on flavor. Browned leeks turn the finished soup a dull grayish color and add a bitter edge.
Blending: Smooth is the goal, gummy is what happens 20 seconds later.
Potatoes: Scoop out a cup or two of the cooked potatoes before you blend, then stir them back in at the end.
Saving: It will set up in the fridge. Thin it with a splash of broth while reheating.
Storage: Refrigerate up to 3-5 days, or freeze up to 4-6 months. Since there is no dairy, it will not split when thawed. Thaw in the fridge, then reheat gently, thinning with a splash of broth as needed.
