Loaded Baked Potato Soup

Loaded baked potato soup takes the familiar flavours of a dressed baked potato and turns them into a hearty, spoonable dinner. Floury russet potatoes give the base its natural body, with part of the soup blended for creaminess while a few chunks remain for texture. Crisp streaky bacon, sharp cheddar and spring onions bring the recognisable loaded-potato finish, and sour cream adds the tang that keeps the richness in check. It is an easy American-style comfort soup, substantial enough for a cold evening and flexible enough to finish with extra cheese, bacon or herbs at the table.

Why this recipe works

  • Creamy without being heavy: Partly blending the tender potatoes thickens the soup naturally while leaving some chunks for a more satisfying texture.
  • Layered savoury flavour: Cooking the onion in bacon fat and butter gives the base a deeper flavour before the stock, potatoes and dairy are added.
  • Classic loaded topping balance: Cheddar, bacon, spring onions and sour cream bring the familiar richness, crunch, freshness and tang of a loaded baked potato.

Texture tips

  • For a thicker soup: Blend a little more of the potato base before adding the cheese and sour cream.
  • For a looser consistency: Stir in a little extra milk gradually until the soup reaches the texture you prefer.
  • Keep the dairy smooth: Warm gently after adding milk and sour cream; avoid boiling, as high heat can cause the dairy to split.

Ingredient notes

  • Use floury potatoes: Russet-style potatoes break down well during simmering, helping create a naturally thick, creamy base.
  • Richer milk options: Whole milk can be used instead of low-fat milk for a fuller, rounder finish.
  • Sour cream timing matters: Stir sour cream in just before serving so its tang stays fresh and the texture remains smooth.

Make-ahead tips

  • Make ahead: The soup can be cooked and refrigerated for up to 3 days, then reheated gently before serving.
  • Reheat slowly: Warm in a saucepan over low heat, stirring often, and avoid boiling to protect the dairy-based texture.
  • Keep toppings fresh: For the best contrast, reserve some bacon, cheese and spring onions separately and add them just before serving.

Common mistakes

  • Over-blending the soup: Blending until completely smooth removes the loaded baked potato character; leave some potato pieces for texture.
  • Letting the base catch: Stir occasionally while the potatoes simmer, especially as the soup thickens near the bottom of the pan.
  • Boiling after dairy is added: Once the milk, cheese and sour cream are in the pot, use gentle heat only to keep the soup creamy.

  1. Put the streaky bacon in a frying pan over medium heat and cook for 8 to 10 minutes, turning, until crisp. Transfer to a plate and leave to cool, then crumble or roughly chop; keep the bacon fat in the pan.
  2. Meanwhile, peel the potatoes and cut into roughly 2 cm chunks. Finely chop the onion, thinly slice the spring onions, and grate the cheddar cheese.
  3. Add the unsalted butter to the bacon fat in the pan and melt over medium heat. Add the onion and cook for 6 to 8 minutes until softened but not browned.
  4. Stir in the plain flour and cook for 1 minute, stirring constantly, to remove the raw flour taste. Gradually stir in a splash of the chicken stock to make a smooth paste, then add the remaining stock.
  5. Tip in the potatoes and fine sea salt, bring to a gentle simmer, then cook for 15 to 18 minutes until the potatoes are very tender. Stir occasionally to prevent sticking.
  6. Blend the soup briefly with an immersion blender, leaving some chunks for texture. Stir in the low-fat milk and warm gently for 2 to 3 minutes until steaming, without boiling.
  7. Take the pan off the heat and stir through most of the cheddar cheese, most of the spring onions, and most of the bacon, reserving a little of each for topping. Stir in the sour cream just before serving so it stays smooth and tangy.
  8. Ladle into bowls and finish with the reserved bacon, cheddar cheese, and spring onions. Serve straight away while hot.

Recipe notes

Tips

  • For the thickest texture, blend a little more of the soup, then loosen with a splash more low-fat milk if needed.
  • Warm the soup gently after adding low-fat milk and sour cream; boiling can make dairy split and dull the flavour.

Substitutions

  • Replace low-fat milk with whole milk for a richer finish.
  • Replace cheddar cheese with gruyere cheese for a nuttier, more mellow topping.
  • Replace sour cream with crème fraîche for a slightly less tangy, silkier finish.

Storage

  • Refrigerate up to 3 days
  • Cool quickly, cover and refrigerate. Reheat gently in a saucepan over low heat, stirring often, until piping hot; avoid boiling to keep the low-fat milk and sour cream smooth.
