Ingredients You’ll Need

Each ingredient in this Scottish Cullen Skink Soup Recipe plays a key role in building layers of flavor, from the silky milk to the fresh parsley. Look out for good-quality smoked haddock—it makes all the difference!

• Milk: Whole milk works best for richness; bringing it gently to a simmer helps infuse the flavors.
• Parsley Sprigs: Use the stalks in the simmering broth and save the leaves for a fresh garnish.
• Bay Leaf: Adds a subtle herbaceous depth—don’t skip it!
• Smoked Haddock Fillet: Choose unsalted, preferably undyed to avoid bitterness and get that authentic smoke flavor.
• Unsalted Butter: For gently softening the onions; unsalted lets you control the saltiness.
• Onion: Finely chopped for sweetness, cooked low and slow to avoid burning.
• Mashed Potatoes: Either store-bought or homemade; they thicken the soup creating that signature creamy texture.
• Kosher Salt and Freshly Ground Black Pepper: Season carefully since smoked fish can be salty.
• Crusty Bread: Optional but highly recommended for dipping and soaking up every last drop.

Variations

I love how adaptable this Scottish Cullen Skink Soup Recipe is—making it your own is part of the fun. Over time, I’ve played around a bit with textures and herbs to suit what we’re craving.

• Using Fresh Potatoes: I sometimes swap the mashed potatoes for fresh peeled and diced ones cooked in the broth; it gives a heartier bite.
• Herb Twists: Adding a bit of fresh dill alongside parsley can bring a bright, slightly different aromatic note.
• Dairy-Free Option: You can use a creamy plant-based milk and vegan butter substitutes to keep it cozy but dairy-free.
• Adjusting Smokiness: If smoked haddock isn’t available, smoked salmon or a touch of smoked paprika can work as a backup—though it’s not quite the same.

How to Make Scottish Cullen Skink Soup Recipe

Step 1: Infuse Milk with Haddock and Herbs

Start by gently heating the milk along with the parsley sprigs, bay leaf, and smoked haddock fillets in a saucepan. Bring the milk just to a gentle boil, then lower the heat to a simmer for about 3 minutes—this helps the flavors seep out nicely without scalding the milk. I always remove the pan from heat and let it sit for 5 minutes to really infuse the smokiness and herb notes. Be patient here; this step is the soul of the soup’s flavor!

Step 2: Prepare the Base with Onions and Butter

While the broth is infusing, melt your butter over medium-low heat in a separate large saucepan and add the finely chopped onion. Cook slowly until translucent—about 5 minutes—taking care not to brown or burn the onions because that’ll throw off the delicate flavors later. It’s worth the slow gentle cook here!

Step 3: Make the Soup Creamy and Add Haddock

Strain the infused milk through a fine mesh sieve, discarding the herbs from the liquid. Add this strained broth into your butter and onion base, then stir in the mashed potatoes, breaking them up so they dissolve and thicken the soup beautifully. Next, carefully flake the smoked haddock into bite-sized chunks—making sure to pick out any bones—and gently fold it into the soup. This is where your soup starts coming together and smelling irresistible!

Step 4: Finish with Herbs and Seasoning

Lower the heat to keep everything at a gentle simmer and add the finely chopped fresh parsley leaves. Let the soup warm through for about 5 minutes. Be careful not to stir too vigorously here; you want firm chunks of haddock, not flakes by the spoonful! Taste and season with kosher salt and freshly ground black pepper—remember, the smoked haddock can be salty, so go easy on the salt initially.

Step 5: Serve with Garnishes and Bread

Ladle the soup into bowls, garnish with some fresh parsley leaves for a pop of color and freshness, and crack some more pepper on top if you like a little kick. Serve with crusty bread on the side—it’s the perfect vessel for soaking up this creamy, smoky broth. Trust me, bowl in hand, spoonful after spoonful, it’s pure comfort.

How to Serve Scottish Cullen Skink Soup Recipe

Garnishes

I’m a huge fan of freshly chopped parsley leaves for that vibrant green burst and fresh bite on top. Sometimes, I like adding a crack of black pepper or even a small drizzle of good olive oil to finish it off. It’s these little touches that take the soup from good to great in presentation and flavor.

Side Dishes

Crusty bread is my go-to here—think sourdough or a rustic country loaf, perfect for dunking. Occasionally, I throw together a simple green salad or some steamed greens like kale to balance the richness. It makes for a quick, satisfying meal.

Creative Ways to Present

For a special gathering, I serve the soup in mini cast-iron pots or rustic cups with a parsley sprig perched on top. You can also accompany it with a small ramekin of chili oil or freshly cracked peppercorns so guests can customize their bowl. It’s simple but adds a lovely personal touch that impresses every time.

Make Ahead and Storage

Storing Leftovers

Once cooled, store your Scottish Cullen Skink Soup in an airtight container in the fridge for up to 2 days. I usually keep the garnish separate so the parsley stays fresh and the bread doesn’t get soggy. Reheat gently on the stove to avoid curdling.

Freezing

Freezing this soup is tricky because dairy can separate, but if you need to, freeze without the garnish and mashed potatoes to maintain texture better. When thawing, reheat slowly and consider stirring in fresh mashed potatoes when warming to restore creaminess.

Reheating

I always reheat Scottish Cullen Skink Soup gently over low heat, stirring occasionally to keep it smooth. If it’s too thick, a splash of milk helps loosen it up without losing creaminess. Avoid microwaving if possible—it tends to break the texture.
