This traditional Scottish soup combines tender potatoes, gently cooked onions, and flakes of smoked haddock in a wonderfully creamy, comforting broth. It’s simple, satisfying, and packed with the distinctive smoky flavour that makes this dish so special.
Originating in the small fishing town of Cullen on Scotland’s northeastern coast, Cullen Skink has become one of Scotland’s best-loved traditional dishes.

Traditional Scottish Cullen Skink
Ingredients
Equipment
Method
- Place the smoked haddock in a medium saucepan with the milk and bay leaf. Heat gently until the milk is just below a simmer. Cover and cook over low heat for approximately 6–8 minutes, or until the fish is opaque and flakes easily. Do not boil.
- Lift the haddock from the milk with a slotted spoon. Set aside until cool enough to handle, then remove any skin and bones and flake the fish into large pieces. Reserve the poaching milk and discard the bay leaf.
- Melt the butter in a large heavy-bottomed saucepan over medium-low heat. Add the onion and leek and cook gently for 6–8 minutes, stirring occasionally, until softened but not browned.
- Add the diced potatoes and water to the saucepan. Pour in the reserved poaching milk, stir gently, and bring to a very gentle simmer. Cook for approximately 12–15 minutes, stirring occasionally, until the potatoes are tender. Keep the heat low to prevent the milk from boiling vigorously or catching on the bottom.
- Use the back of a wooden spoon to mash a small portion of the cooked potatoes against the side of the pan. Stir them back into the broth to give the soup a naturally creamy consistency.
- Gently fold the flaked haddock into the soup. Heat for another 2–3 minutes until the fish is thoroughly hot. Add black pepper and taste before adding any salt, as smoked haddock can already be quite salty.
- Remove from the heat and ladle into warm bowls. Sprinkle with chopped fresh parsley and serve with crusty bread, if desired.
Notes
What Is Cullen Skink?
Cullen Skink is a traditional Scottish soup made primarily with smoked haddock, potatoes, onions, and milk.
Unlike many American seafood chowders, which often include cream, bacon, or several different types of seafood, Cullen Skink is traditionally a much simpler dish.
The smoked haddock provides the soup’s distinctive flavour, while the potatoes add body and a comforting texture.
Some versions include leeks, butter, or a little cream, but the essential combination of smoked fish, potatoes, and milk remains the heart of the recipe.
Where Does Cullen Skink Come From?
Cullen Skink takes its name from Cullen, a small coastal town in Moray, northeastern Scotland.
The town has a long fishing heritage, and smoked haddock was traditionally an important part of the local diet.
The word skink was historically associated with soups and broths in Scotland. Although earlier versions of skink could refer to meat-based broths, the name became associated with this distinctive smoked-fish soup.
Today, Cullen Skink is enjoyed throughout Scotland and is frequently found on restaurant menus, particularly during the colder months.
It’s a wonderful example of traditional Scottish cooking: making something delicious and satisfying from a handful of simple ingredients.
What Does Cullen Skink Taste Like?
Cullen Skink is creamy, savoury, gently smoky, and wonderfully comforting.
The smoked haddock gives the soup a rich depth of flavour without making it overwhelmingly fishy.
Tender potatoes make it hearty enough to serve as a main meal, while the milk creates a smooth, comforting broth.
If you enjoy creamy seafood chowders, there’s a good chance you’ll love Cullen Skink.
The biggest difference is the unmistakable flavour of traditionally smoked haddock.
Finding Smoked Haddock in America
This is probably the biggest challenge American cooks will encounter when making authentic Cullen Skink.
In Britain, smoked haddock is commonly available in supermarkets and fishmongers. In the United States, it can take a little more searching.
What to Look For
Ideally, look for cold-smoked haddock, which is smoked for flavour but still needs cooking.
You may find it at specialist seafood shops, British food retailers, or online seafood suppliers.
Naturally smoked haddock is often pale golden or beige, while some commercially smoked varieties have a much brighter yellow colour.
Both can be used, although naturally smoked haddock is an excellent choice when available.
Can You Substitute Another Fish?
Yes, although the flavour will be different.
Cold-smoked cod is one of the closest alternatives, provided it’s a raw, cook-before-eating product.
Fresh haddock or cod can also be used, but you’ll lose the characteristic smoky flavour that defines Cullen Skink.
If you’re using fresh fish, a small amount of smoked paprika can provide a hint of smokiness, although it won’t reproduce the traditional taste.
Avoid substituting hot-smoked salmon without adjusting the recipe, as its texture, flavour, and saltiness are quite different.
British Ingredients Explained for American Kitchens
One of the things I love about Cullen Skink is that most of the ingredients are already familiar to American cooks.
Smoked haddock: Look for cold-smoked haddock that requires cooking, rather than ready-to-eat smoked fish.
Potatoes: Yukon Gold potatoes are an excellent choice because they become tender and creamy without completely falling apart.
Onions: A regular yellow onion works beautifully. Some traditional recipes use leeks instead.
Milk: Whole milk gives the soup a lovely richness without needing large quantities of cream.
Butter: Unsalted butter allows you to control the seasoning, especially because smoked fish can already be salty.
Parsley: Fresh parsley adds colour and freshness just before serving.
Brit & Skillet Tip: Cook Your Cullen Skink Gently
One of the secrets to a beautifully creamy Cullen Skink is gentle cooking.
Once the milk has been added, avoid boiling the soup vigorously. A gentle simmer helps keep the fish tender and reduces the chance of the milk separating.
A heavy-bottomed pan distributes heat evenly, making it easier to maintain a steady temperature.
For recipes like this, I particularly like the Staub Traditional Deep Skillet, provided its capacity is sufficient for the quantity of soup you’re preparing.
It’s also a versatile piece of cookware for other traditional British dishes, from hearty stews to savoury one-pan meals.
And remember: smoked haddock can vary considerably in saltiness, so always taste the soup before adding extra salt.
How to Make Cullen Skink Extra Creamy
Traditional Cullen Skink doesn’t necessarily require heavy cream.
The potatoes naturally help thicken the soup, particularly if you mash a small portion against the side of the pan before serving.
For a thicker texture, you can remove a little of the cooked potato, mash it with some of the broth, and stir it back into the soup.
If you prefer a richer version, a small splash of heavy cream can be added at the end.
However, I recommend trying the traditional milk-based version first. It’s wonderfully comforting without feeling too heavy.
What to Serve with Cullen Skink
Cullen Skink is hearty enough to enjoy as a light main course, especially when served with crusty bread.
In Scotland, it’s often enjoyed with traditional bread or oatcakes.
For a lovely British-inspired meal, serve it with warm bread and follow with a comforting dessert such as our Traditional British Apple Crumble.
And if you enjoy classic British fish dishes, you might also like our Traditional British Fish Pie, another wonderfully comforting recipe featuring tender fish in a creamy sauce.
Can You Make Cullen Skink Ahead of Time?
Yes! Cullen Skink can be made ahead, although it’s at its best when freshly prepared.
Allow the soup to cool promptly and refrigerate it in an airtight container within two hours of cooking.
Store it in the refrigerator for up to two days.
When reheating, warm it gently on the stovetop until thoroughly hot, stirring occasionally. Avoid vigorous boiling, which can make the fish tough and affect the creamy texture.
If the soup has thickened in the refrigerator, add a splash of milk to loosen it.
Can You Freeze Cullen Skink?
You can, but the texture may change.
Milk-based soups sometimes separate after freezing, and potatoes can become slightly grainy when thawed.
For the best results, enjoy Cullen Skink fresh or refrigerate leftovers for the following day.
If you do freeze it, cool it promptly, freeze in suitable containers, and thaw in the refrigerator before reheating thoroughly.
Frequently Asked Questions

Can I Make Cullen Skink Without Cream?
Absolutely! Traditional versions commonly use milk rather than heavy cream.
Can I Use Fresh Haddock?
Yes, but the soup won’t have the same distinctive smoky flavour. Cold-smoked haddock is strongly recommended for an authentic result.
Is Cullen Skink Very Fishy?
