**Summary:**

Four light main-dish servings of rustic potato, leek and white bean soup in about 45–50 minutes. No dairy-free cream or blender required.

A pot of potato and leek soup is a useful place to start when you want a warm vegan dinner without buying a carton of dairy-free cream. Here, white beans and gently mashed potatoes give the broth body, while soft leeks, thyme and a little lemon keep the flavor simple.

**Recipe note:** This source-informed recipe has not been kitchen-tested by 1 Month Vegan Challenge. Times and yield are estimates; use the tenderness and consistency cues below. The cover is an AI-generated serving illustration, not a photograph of a tested batch.

## At a glance

- **Serves:** 4 as a light main, with bread if wanted
- **Prep:** about 15 minutes
- **Cook:** about 30–35 minutes
- **Total:** about 45–50 minutes
- **Equipment:** large soup pot with lid, colander, knife and potato masher

## Ingredients

US cups and spoons are used. Metric amounts are rounded practical equivalents. Weigh the prepared leeks if possible, since their size varies considerably.

- 2 tablespoons (30 ml) olive oil
- 2 medium-large leeks, white and pale-green parts only, about 3 cups sliced (300 g after trimming)
- 3 garlic cloves, finely chopped (about 9 g)
- 1 teaspoon dried thyme (about 1 g)
- 1½ lb (680 g) yellow potatoes, scrubbed, peeled if preferred, and cut into ½-inch (1.3 cm) pieces
- 2 cans cannellini beans, 15 oz (425 g) each before draining, rinsed and drained; about 3 cups (480–500 g) drained beans
- 4 cups (960 ml) low-sodium vegan vegetable broth, plus up to 1 cup (240 ml) extra broth or water to adjust the thickness
- ¼ teaspoon fine salt (about 1.5 g), then more only as needed
- ¼ teaspoon ground black pepper (about 0.5 g)
- 1 tablespoon (15 ml) lemon juice, plus more to taste
- 2 tablespoons chopped fresh parsley (about 8 g), optional
- 4 slices vegan bread, optional, for serving

## How to make it

1. **Wash the leeks thoroughly.** Trim off the roots and tough dark-green tops. Split the usable stalks lengthwise and rinse between the layers under running water. Slice thinly, rinse again in a colander if any grit remains, and drain. Scrub and cut the potatoes.
2. **Soften, rather than brown.** Warm the oil in the pot over medium-low heat. Add the leeks and cook for 8–10 minutes, stirring often, until soft and reduced in volume. If the edges catch or darken, lower the heat and add a tablespoon of water. Stir in the garlic and thyme for about 30 seconds.
3. **Simmer until the potatoes yield.** Add the potatoes, drained beans, 4 cups (960 ml) broth, salt and pepper. Bring to a gentle boil, then lower the heat, partly cover and simmer for 18–25 minutes. Stir occasionally. A potato piece should break easily when pressed with a fork; keep cooking if its center is firm.
4. **Make it creamy without a blender.** Turn off the heat. Use a potato masher directly in the pot to crush some of the potatoes and beans, leaving others whole. Stir and assess the texture. Add extra broth or water, ¼ cup (60 ml) at a time, if it feels closer to mash than soup. Return to a gentle simmer if needed to heat the added liquid.
5. **Finish and serve.** Stir in the lemon juice. Taste a cooled spoonful before adding more salt, pepper or lemon. Ladle into four bowls, finish with parsley if using, and offer bread alongside.

## Small fixes that help

- **Too thin?** Mash a little more, then simmer uncovered for a few minutes, stirring so the base does not stick.
- **Too thick?** Add a splash of broth or water. The soup continues to thicken as it stands and chills.
- **Still gritty?** Leek grit does not dissolve during cooking. Careful washing before cooking is the best fix.
- **Want a smoother soup?** An immersion blender can be used briefly with its blade fully submerged, following its manufacturer's hot-liquid instructions. Avoid prolonged blending, which can make potatoes gluey. The masher method is the simplest option.

## Vegan substitutions and budget tips

**Beans:** Great northern or navy beans work in the same drained amount. Use already fully cooked beans if cooking from dried; do not add dry beans directly to this short soup recipe.

**Leeks:** If they are expensive, use about 2 cups (300 g) chopped yellow onion instead. Cook until soft; the soup will have a stronger onion flavor. No need to buy both onions and leeks.

**Potatoes:** Yellow potatoes give a pleasant creamy texture. Peeled russets also work, but stick with gentle hand-mashing rather than extensive blending.

**Broth and toppings:** Check that broth or bouillon contains no chicken, beef or dairy ingredients. Bouillon prepared to its label directions can be cheaper than cartons; reduce added salt if it is salty. Parsley and bread are optional, so skip them rather than buying a whole extra item. Check bread for milk, eggs or honey if serving it.

**Allergen needs:** The base recipe uses no nuts or dairy, but packaged broth and bread may contain allergens. For a gluten-free meal, use verified gluten-free broth and bread or omit the bread. Check labels and cross-contact guidance for your needs.

## Make ahead, store and reheat safely

Wash and slice the leeks up to a day ahead and refrigerate in a covered container. For the simplest meal prep, cook the complete soup, portion it and chill it promptly.

- Divide leftovers into shallow containers and refrigerate within 2 hours of cooking, or within 1 hour when the surrounding temperature is above 90°F (32°C). Do not leave a large pot on the counter to cool completely.
- Keep the refrigerator at 40°F (4°C) or below. Eat refrigerated soup within 3–4 days, or freeze portions promptly for later.
- Freeze in suitable containers with expansion space; aim to use within 2 months for best texture. Potatoes may become slightly grainy after freezing. Thaw overnight in the refrigerator, not on the counter.
- Reheat the portion you need, adding a little water as necessary. Stir frequently, bring the soup to a boil and check that it reaches at least 165°F (74°C) throughout with a food thermometer. Reheating does not reset its refrigerated storage time.
