Oh, let me tell you about my absolute favorite way to enjoy herring—Śledź po Kaszubsku! This traditional Kashubian dish has been a staple in my family for generations, and once you try it, you’ll understand why. The magic happens when salty herring meets sweet onions and tangy sour cream in the most perfect harmony. What I love most? It’s ridiculously simple to make—just a bit of soaking, layering, and waiting (the hardest part!). Trust me, the wait is worth it. After 24 hours in the fridge, those flavors meld together into something truly special. It’s the kind of dish that tastes like home, whether you’re from Kashubia or just discovering Polish flavors for the first time.

Ingredients for Śledź po Kaszubsku
(Pro tip: Measure everything before you start—it makes the layering process so much smoother!)
- 500g salted herring fillets (soaked in cold water for 12 hours and drained—this removes excess salt)
- 2 large onions (thinly sliced—I like them paper-thin so they soften nicely)
- 200ml sour cream (full-fat works best for that luscious texture)
- 2 tablespoons mustard (I use classic yellow, but Dijon works too)
- 1 tablespoon sugar (balances the tang perfectly)
- 1 teaspoon freshly ground black pepper
- 2 bay leaves (for that subtle earthy aroma)
- 5 allspice berries (my grandma’s secret flavor booster!)
How to Make Śledź po Kaszubsku
Okay, let’s get into the fun part—making this deliciousness happen! Don’t let the marinating time scare you; most of it is hands-off, I promise. Just follow these simple steps, and you’ll have a jar full of flavor-packed herring ready to impress.
Preparing the Herring
- First, soak those salted herring fillets in cold water for a full 12 hours. (I usually do this overnight—set it and forget it!) Change the water at least once halfway through to really get rid of that excess salt. Trust me, this step makes all the difference.
- Drain the fillets well and pat them dry with paper towels. Then, cut them into bite-sized pieces—about 2-inch chunks work perfectly. No need to be precise here; rustic is good!
Mixing the Sauce
- In a medium bowl, whisk together the sour cream, mustard, sugar, and black pepper until smooth. You want it creamy but still pourable—if it’s too thick, add a teaspoon of water to loosen it up.
- Taste and adjust! Want it tangier? Add a bit more mustard. Sweeter? A pinch more sugar. This is your herring—make it yours!
Layering and Marinating
- Now, grab a clean, airtight glass jar (a 1-liter size works great). Start with a layer of herring pieces at the bottom, then add a handful of those thin onion slices. Tuck in a bay leaf and a couple allspice berries here and there as you go.
- Repeat the layers until you’ve used up all your ingredients, finishing with a nice layer of onions on top. Pour that creamy sauce over everything, making sure it seeps into all the nooks and crannies.
- Seal the jar tightly and pop it in the fridge for at least 24 hours—48 is even better! The longer it sits, the more those flavors mingle and become magical.
And that’s it! See? Told you it was easy. Now comes the hard part: waiting. But oh, the payoff is so worth it.
Tips for Perfect Śledź po Kaszubsku
- Trust your tastebuds—after mixing the sauce, adjust the sugar and mustard to hit that perfect sweet-tangy balance for you.
- Patience pays off—while 24 hours is good, letting it marinate for 2-3 days makes the flavors incredible.
- Slice onions paper-thin—they soften beautifully and meld into the dish instead of staying crunchy.
- Use a glass jar—plastic can absorb smells, and you’ll want every bit of that delicious marinade!
Serving Suggestions for Śledź po Kaszubsku
Oh, how I love serving this! Traditionally, we enjoy it chilled with simple boiled potatoes or thick slices of dark rye bread—the perfect canvas for those bold flavors. For a real Kashubian feast, add pickled cucumbers and a drizzle of good olive oil. It’s also fantastic with a crisp, cold beer!
Storage & Reheating
This beauty keeps wonderfully in the fridge for 3-4 days—if it lasts that long! Just keep it in its airtight jar. And no reheating needed—serve it straight from the fridge for that perfect chilled bite.
Śledź po Kaszubsku FAQs
Can I use fresh herring instead of salted?
Absolutely! Just skip the soaking step and reduce the sugar slightly—fresh herring is milder. You might want to add a pinch of salt to the sauce though.
What can I substitute for sour cream?
Greek yogurt works in a pinch, but it’ll be tangier. For richness, try crème fraîche—just thin it with a splash of milk if needed.
How do I know if the herring is soaked enough?
Taste a tiny piece after soaking—it should be pleasantly salty but not overwhelming. If still too salty, soak another hour or two.
Can I add other spices?
Oh yes! My aunt adds a few peppercorns, and some folks love a sprinkle of dill. Just keep the bay leaves and allspice—they’re essential.
Why glass jars?
Plastic can pick up fishy smells forever (learned that the hard way!). Glass keeps everything fresh and lets you see those beautiful layers.
