Ingredients You’ll Need

Every ingredient in this Scottish Cullen Skink Fish Soup Recipe plays a crucial role. The smoked haddock brings the smoky, savory heart, while the mashed potatoes naturally thicken the broth, making it satisfyingly creamy. I always recommend fresh parsley – it brightens things up beautifully. When shopping, try to find smoked haddock that isn’t artificially dyed for the best flavor.

• Milk: Use whole milk for creaminess that balances the smoky fish.
• Parsley sprigs: Fresh parsley with leaves and stalks separated for layering flavor and garnish.
• Bay leaf: Adds a subtle herbal undertone during simmering.
• Smoked haddock fillet: The star ingredient – choose unsalted and preferably undyed for the best taste.
• Unsalted butter: For gently cooking the onions and adding richness without salt overload.
• Onion: Finely chopped to melt into the soup and add a sweet foundation.
• Mashed potato: Store-bought or homemade – it’s your secret weapon for thickness and creaminess.
• Kosher salt: To adjust seasoning carefully because the fish brings natural saltiness.
• Freshly ground black pepper: Adds that lovely warming kick at the end.
• Crusty bread (optional): Perfect for dunking and soaking up every last drop.

Variations

I love how this Scottish Cullen Skink Fish Soup Recipe can be tweaked to suit different tastes. Sometimes I add a bit of celery for crunch, or swap in a different smoked white fish if haddock isn’t available where you live. Don’t be afraid to personalize it to your family’s preferences because a soup is all about comfort, right?

• Different fish variation: Using smoked cod instead of haddock worked great for me once — still smoky but with a slightly different texture.
• Vegetarian twist: Use smoked smoked paprika and smoked seaweed broth to mimic smoky flavor without fish; it’s not traditional but surprisingly tasty.
• Extra herbs: Adding a touch of fresh thyme or dill alongside parsley can bring a lovely fresh complexity.
• Vegan adaptation: Swap butter for olive oil, use plant-based milk, and a smoked vegetable broth — definitely not classic, but friendly for all diets.

How to Make Scottish Cullen Skink Fish Soup Recipe

Step 1: Infuse the Milk with Haddock and Herbs

Start by gently heating the milk with the smoked haddock fillet, parsley sprigs (with leaves and stalks separated), and a bay leaf in a large saucepan. Bring it just to a gentle boil then turn down to a low simmer for about 3 minutes. Remove from heat and let everything sit, covered, for 5 minutes. This step is such a game changer because the milk learns all that amazing smoky and herbal flavor without overcooking the fish. I’ve found that patience here really pays off.

Step 2: Prepare the Onion and Butter Base

While the milk infuses, melt unsalted butter in another large pan over medium-low heat and add finely chopped onions. Cook gently until the onions turn translucent, about 5 minutes, but watch carefully to avoid browning. This soft, buttery onion base adds natural sweetness to balance the smoky haddock later — trust me, it’s worth the gentle attention here.

Step 3: Combine Ingredients and Thicken the Soup

Strain the infused milk to remove herbs, then pour it into the butter-onion pan. Add mashed potatoes and stir well until they dissolve into the liquid, thickening the soup beautifully. When I first tried this, I was worried about lumps, but stirring patiently while breaking up the potatoes helps you get that perfectly smooth soup texture.

Step 4: Flake the Haddock and Finish Cooking

Carefully remove the haddock from the milk before straining, then flake it into bite-sized chunks, discarding any bones. Add the flakes to the soup, return the pan to a gentle simmer, and stir in the chopped parsley leaves you set aside earlier. Cook just long enough to warm the fish through, about 5 minutes. Be gentle when stirring because you don’t want those tender fish pieces to break apart – that’s the key to a chunkier, homey soup texture.

Step 5: Season and Serve

Now comes the finishing touch: season lightly with kosher salt and freshly ground black pepper. I always recommend tasting first because the smoked haddock brings a salty punch on its own. Serve garnished with fresh parsley leaves and pepper, alongside some crusty bread for dunking — your soup is ready to wow!

How to Serve Scottish Cullen Skink Fish Soup Recipe

Garnishes

I always garnish with a few fresh parsley leaves and a sprinkle of freshly cracked black pepper because it adds that bright pop of color and a hint of freshness against the creamy rich soup. Sometimes, if I’m feeling fancy, I add a drizzle of good olive oil or a squeeze of lemon to brighten things further — it’s a game changer, especially if your soup feels a little heavy.

Side Dishes

Pair this soup with thick slices of crusty sourdough or a warm buttered roll. On a colder weekend, I like to serve it alongside simple roasted root vegetables or a crisp green salad to keep things balanced. My family also enjoys a bit of aged cheddar melted on toasted bread as a side — perfect for soaking up every last bite.

Creative Ways to Present

For special occasions, I like to serve the Cullen Skink in small, individual bread bowls carved out from round sourdough loaves — it looks rustic and fun, plus no bowls to wash up! Adding a sprinkle of chopped chives or a swirl of cream on top makes for a pretty presentation. You can also serve alongside a Scottish oatcake for an extra authentic touch.

Make Ahead and Storage

Storing Leftovers

Once cooled, I store leftovers in an airtight container in the fridge, and the soup keeps well for up to 2 days. The flavors actually mellow and meld together nicely after resting overnight, so leftovers might even taste better to you the next day.

Freezing

Freezing Cullen Skink can be a bit tricky because dairy and potatoes can separate, but I’ve had good results by letting the soup cool completely, then freezing it in portions. When reheated gently, stirring frequently, it comes back together nicely. Just know the texture might be slightly different, but the flavor holds up well.

Reheating

Reheat leftovers over low heat on the stove, stirring gently until warmed through to avoid breaking up the fish too much. Adding a splash of milk if it thickens too much helps restore the lovely creamy consistency. Microwaving works too but be careful to warm it evenly.
