Heart healthy potato leek soup
This simple heart healthy potato leek soup is creamy without heavy cream and focuses on soft textures and gentle flavors so it is easy to eat and digest. The recipe makes 1 to 2 servings and cooks in one pot, making it quick to finish on a weeknight.

Cooking for one or two is easier when recipes use a single pan and simple steps. This soup uses common ingredients and a short simmer so you end up with a smooth, comforting bowl and minimal cleanup.
The texture is adjustable. You can mash lightly for a rustic soup or blend until silky for an easy-to-chew meal. Both keep well and reheat gently for another soft meal the next day.
Ingredients You’ll Need

- 1 tablespoon olive oil
- 1 medium leek, white and light green parts only, thinly sliced and rinsed
- 1 small yellow onion, diced
- 2 medium Yukon Gold potatoes, peeled and cut into 1-inch cubes (about 2 cups)
- 2 cups low-sodium vegetable broth or low-sodium chicken broth
- 1/2 cup low-fat milk or unsweetened plant milk
- 1 small garlic clove, minced
- 1/4 teaspoon dried thyme or 1 teaspoon fresh thyme leaves
- Salt to taste, optional – start with 1/8 teaspoon
- Freshly ground black pepper to taste
- 1 tablespoon chopped fresh chives or parsley for garnish
- Simple sides: a soft whole grain roll, a slice of toast, or a spoonful of plain yogurt
These ingredients make 1 to 2 servings and are easy to scale up for more portions.
Step-by-Step Recipe

- Heat the oil in a medium saucepan over medium heat. Add the sliced leeks and diced onion and cook, stirring occasionally, until soft and translucent, about 6 to 8 minutes.
- Add the minced garlic and thyme and cook 30 seconds until fragrant.
- Add the potato cubes and pour in the low-sodium broth. Bring to a gentle simmer, cover, and cook until the potatoes are very tender, 15 to 20 minutes.
- Turn off the heat. For a thin, rustic soup, use a potato masher and mash some of the potatoes in the pot. For a very smooth, easy-to-chew texture, use an immersion blender to puree until silky. Stir in the milk.
- Warm the soup gently over low heat if needed. Taste and add a small pinch of salt if desired. Add pepper and chopped chives to finish and serve warm.

Light digestion swaps

Quick tips
