Creamy Potato Leek Soup for Tired Weeknights
One pot, pantry staples, done in 40 minutes — pure comfort with zero drama.
This is the soup you make when you're cold, tired, and just need something that feels like a hug. Potato leek soup is the kind of classic that sounds fancy but asks almost nothing of you — chop a few things, let the pot do the work, blend if you feel like it. Expect a thick, creamy, savory bowl that tastes like you spent way more time than you did. It reheats beautifully, so tomorrow's lunch is already handled. No special skills, no weird ingredients, no stress.
Ingredients
- 2 tbsp unsalted butter
- 3 unit leeks — white and light green parts only, sliced into half-moons and rinsed well
- 4 unit garlic cloves — minced
- 1.5 lb Yukon Gold potatoes — peeled and cut into 1-inch chunks
- 4 cup vegetable broth — low-sodium preferred
- 1 cup whole milk or half-and-half
- 1 tsp kosher salt — plus more to taste
- 0.5 tsp black pepper
- 0.25 tsp dried thyme
- 1 tbsp sour cream — optional, stirred in at the end for extra richness
- 2 tbsp fresh chives or parsley — chopped, for serving
Method
- 1 Melt the butter in a large pot over medium heat. Add the sliced leeks and cook, stirring occasionally, for 6–8 minutes until softened and just starting to turn golden.
- 2 Add the garlic and dried thyme. Stir and cook for 1 minute until fragrant.
- 3 Add the potato chunks and vegetable broth. Bring to a boil, then reduce heat to medium-low. Cover and simmer for 18–20 minutes, until the potatoes are completely tender when pierced with a fork.
- 4 Remove from heat. Use an immersion blender to blend the soup directly in the pot until smooth and creamy. Alternatively, carefully transfer in batches to a blender — leave the lid slightly vented and hold it down with a towel.
- 5 Stir in the milk or half-and-half. Return the pot to low heat and warm through for 2–3 minutes. Do not boil.
- 6 Taste and adjust salt and pepper. Stir in the sour cream if using.
- 7 Ladle into bowls and top with chives or parsley. Serve with crusty bread if you have it.
Variations
- Add Bacon or Ham — Render 3–4 strips of chopped bacon in the pot before the butter, remove and set aside, then build the soup as written. Stir the crispy bacon in at the end or use it as a topper.
- Vegan Swap — Use olive oil instead of butter and swap the milk for unsweetened oat milk or full-fat coconut milk. Skip the sour cream or use a plant-based version.
- No Leeks? Use Onions — Replace leeks with 2 medium yellow onions, thinly sliced. The flavor is a little sharper but equally good — cook them the same way until soft and golden.
Notes
Leeks hide a lot of dirt between their layers — rinse the sliced rounds in a bowl of cold water and lift them out, leaving the grit behind. For a chunkier texture, blend only half the soup. Leftovers keep in the fridge for up to 4 days; the soup will thicken as it sits — just thin with a splash of broth when reheating.
Equipment that helps
- Immersion blender — Lets you blend the soup directly in the pot so you skip the dangerous hot-liquid-in-blender transfer and save on cleanup.
- Large pot or Dutch oven — A wide, heavy-bottomed pot distributes heat evenly so the leeks soften without scorching.
