Potato leek soup is a smooth, warm dish made with potatoes and leeks cooked in broth. It’s simple, filling, and perfect for chilly days. The flavors are gentle and comforting.
I once added a bit of cream just for fun—made it extra creamy and delicious. Now I always keep a spoonful of cream nearby when I serve it!
If you want, top with a little chopped chives or crispy bacon. It’s a quick way to make this cozy soup even tastier and prettier.
Ingredients & Substitutions
Potatoes: I use starchy potatoes like Russets or Yukon Gold for a thick, creamy soup. If you don’t have these, sweet potatoes work well and add a natural sweetness. Peel and chop evenly for even cooking.
Leeks: Leeks lend a mild, onion-like flavor. Make sure to rinse them well to remove dirt between layers. If leeks aren’t available, you can substitute with shallots or onions, but use a little less to keep the flavor gentle.
Butter or Olive Oil: I prefer butter for richness, but olive oil is a good, lighter option. Use about equal amounts. For a dairy-free version, try coconut oil or a neutral vegetable oil.
Garlic: Fresh garlic adds a lovely aroma. I recommend mincing it finely so it cooks evenly. If fresh garlic isn’t around, garlic powder can be used, but reduce the quantity by half.
Vegetable Broth: I use low-sodium broth to control salt. Chicken broth works too if you’re not vegetarian. For a richer flavor, a splash of white wine can be added during cooking.
How do I blend the soup smoothly without making a mess?
Use an immersion blender directly in the pot for easy blending and less cleanup. If you use a regular blender, blend in small batches, filling the blender only halfway to prevent splatters. Hold the lid with a towel and be careful with hot liquids.
- Start blending at low speed, then gradually increase.
- Keep the blender slightly angled to release steam and avoid splashes.
- Ensure the soup is hot enough for a smooth texture, but not so hot that it splatters.
