Potato and leek soup is a classic for a reason, and this version leans into that — simmered until the potatoes are properly soft, then blended down to something smooth and velvety.

What sets it apart is the topping. Bacon and apple fried together until caramelised, finished with crispy sage, spooned over the top of each bowl. It adds a bit of crunch and sweetness against the smooth soup underneath.

Serve it with a slice of toasted bread on the side and you’ve got a proper bowl of comfort food.

Why You'll Love This Creamy Garlic Potato & Leek Soup

Smooth, velvety soup with a crispy bacon and apple topping

Letting the potatoes simmer until they're really soft, not just tender, is what gets you that smooth texture once it's blended. Rush this step and the soup stays slightly grainy.

The bacon, apple, and sage crust takes it from a simple soup to something a bit more special. The apple picks up the rendered bacon fat as it fries and caramelises beautifully alongside it.

It also freezes well, so it's worth making a double batch and stashing some away for a night when you don't feel like cooking.

Ingredients

Potato & Leek Soup

  • 42 g Unsalted Butter
  • 4 Leeks Sliced
  • 3 Garlic Cloves Chopped
  • 4 All-Rounder Potatoes Diced
  • 1 litre Vegetable Stock
  • 180 ml Thickened Cream
  • Salt & Pepper To Taste

Bacon, Apple & Sage Crust

  • 14 g Unsalted Butter
  • 120 g Streaky Bacon Sliced
  • 1 Red Apple Peeled & Diced
  • 12 g Sage Leaves Chopped
  • Salt & Pepper To Taste
  • 4 slices Bread of Choice To Serve

Method

Potato & Leek Soup

  • Place a large pot over medium-high heat, add the butter, and allow it to melt. Add the leek, garlic, and seasoning to taste. Sauté for 3 minutes, until it starts to soften.
  • Add the diced potato, mix to combine, and sauté for 1 minute. Pour in the stock and bring to a boil. Reduce the heat to medium-low, cover with a lid, and simmer for 30 minutes, or until the potatoes are really soft. Remove the lid and pour in the cream, mixing to combine. Take off the heat.
  • Use an immersion blender to blend the soup to a smooth purée. If using a regular blender or food processor, let the soup cool for at least 45 minutes first — blending boiling hot soup in a plastic blender or processor bowl risks it expanding from the heat and exploding during processing, which can cause serious injury and damage to yourself and your property. Immersion blenders are the safest and easiest option, and are inexpensive to pick up if you don't already have one. Transfer back over low heat, check the seasoning, and keep warm.

Bacon, Apple & Sage Crust

  • Place a pan over medium heat, add the butter, and allow it to melt. Add the bacon and apple, and fry for 4 minutes, or until golden, slightly crispy, and caramelised. Add the sage, season to taste, mix well, and fry for 1 minute, or until the sage is crispy. Remove from the heat.
  • Serve the soup in bowls, top with the bacon, apple, and sage crust, and serve with toasted bread. Dig in.
Chef's Tips
Let the potatoes simmer until they're really soft, not just tender — this is what gives the soup its smooth, velvety texture once blended, rather than staying slightly grainy.
Fry the bacon and apple together so the apple picks up some of the rendered bacon fat — it caramelises beautifully and balances the saltiness of the bacon.
Fry the sage just until crispy, not longer — it can turn bitter if left in the pan too long, so pull it as soon as it crisps up.
Storage & Reheating
Store the soup in the fridge for up to 5 days or in the freezer for up to 6 months, both in an airtight container. It's best to keep the bacon, apple, and sage crust separate — it'll keep in the fridge for up to 5 days. It can also be mixed through the soup instead, though the bacon will lose its crispness once it picks up moisture. To reheat, place the soup into a pot or pan over medium-high heat and, mixing regularly, slowly bring it back to a boil. Alternatively, reheat in the microwave in bursts, mixing between each one.
For a dairy-free or vegan version, substitute the butter for olive oil and the thickened cream for soy or oat milk. The soup won't be quite as rich with these swaps, but will still taste great.

Common Questions
Can I blend the soup in a regular blender?
Yes, but let the soup cool for at least 45 minutes first. Blending boiling hot soup in a plastic blender or food processor bowl can cause it to expand from the heat and force the lid off during blending, which is a genuine burn risk. An immersion blender skips this issue entirely and is worth picking up if you don't already have one.
Can I freeze this soup?
Yes, it keeps in the freezer for up to 6 months in an airtight container. As with most cream-based soups, it can separate slightly once thawed — a good whisk or a quick blitz with an immersion blender while reheating will bring it back together.
Can I make this dairy-free?
Yes, swap the butter for olive oil and the thickened cream for soy or oat milk. It won't be quite as rich, but it'll still taste great and hold together well.
Should I keep the bacon crust separate or mix it through?
Keeping it separate is best if you want it to stay crispy — it'll keep in the fridge for up to 5 days on its own. You can mix it through the soup instead if you're storing leftovers together, but the bacon will lose its crunch once it picks up moisture.

    Although I haven’t yet made the topping, I made the soup. It tastes fantastic; very creamy and a wonderful mixture of flavours. Thanks!
