Polish Pork Meatballs in Onion Gravy (Klopsiki)
Tender pork and beef meatballs simmered in a deeply caramelized onion gravy — Poland's home-style klopsiki, served over kasza or potatoes.
About This Recipe
Klopsiki are Poland's everyday meatballs, a mix of ground pork and beef bound with bread soaked in milk and bound with egg, seasoned simply with salt, pepper and marjoram — a herb that shows up across much of Polish savory cooking and gives these meatballs their distinctly Polish rather than Italian or Swedish character. Rather than a tomato-based sauce, klopsiki are traditionally finished in a rich gravy built from deeply caramelized onions and a light roux, giving the dish a sweeter, more savory-brown profile than meatball dishes from other cuisines. The onions need real time on low heat to develop their full sweetness before the gravy comes together, a step many Polish grandmothers won't rush no matter how long it takes. The meatballs themselves are browned first to build a crust, then finished by simmering directly in the gravy so they absorb its flavor as they cook through completely. Served over buckwheat groats (kasza) or mashed potatoes with a simple cooked vegetable on the side, klopsiki are standard Sunday dinner fare across Polish households, the kind of dish nearly every family has their own slightly different version of.

Instructions
- 1
Soak the bread

- 2

Squeeze excess milk from the bread and combine with ground pork, ground beef, egg, marjoram, salt and pepper. Mix gently and shape into 16 meatballs.
- 3
Caramelize the onions
Melt 2 tbsp butter in a wide pan over low heat, add onions, and cook slowly for 20-25 minutes until deep golden.
Real patience here pays off — rushed onions taste sharp instead of sweet and won't carry the gravy properly.
- 4
Brown the meatballs
Push onions aside, add remaining butter, and brown meatballs on all sides, about 6-7 minutes total.
- 5
Make the gravy
Sprinkle flour over everything in the pan, stir to coat, then gradually whisk in beef stock until smooth.
- 6
Simmer and finish
Simmer 10-12 minutes until the meatballs are cooked through and the gravy thickens. Stir in sour cream off the heat and serve over kasza or mashed potatoes.

Pro Tips
- →
Use dried marjoram, not oregano — the two are related but marjoram has a sweeter, more delicate flavor that's essential to authentic Polish seasoning.
- →
Soak bread in milk rather than using dry breadcrumbs for a noticeably more tender meatball texture.
- →
Stir sour cream in off the heat at the very end so it doesn't curdle in the hot gravy.
Variations
- •
Add a bay leaf and a few allspice berries to the gravy while it simmers for extra depth.
- •
Use all pork for a milder, slightly sweeter meatball.
- •
Serve with buttered noodles instead of kasza for a different texture pairing.
Storage
Refrigerate in the gravy up to 3 days. Reheat gently on the stovetop with a splash of stock to loosen the sauce. Freezes well for up to 2 months, though add sour cream fresh after reheating.
History & Origin
Klopsiki reflect a broader Central European tradition of ground meat dishes bound with bread and egg, distinct from Italian-style meatballs through their use of marjoram and onion gravy rather than tomato sauce. The dish remains a staple of Polish home cooking, with nearly every family having its own slightly different recipe passed down through generations.
Frequently Asked Questions
What can I substitute for marjoram?
A small amount of oregano can work in a pinch, though the flavor is noticeably sharper and less sweet than marjoram, which is the more traditional and distinctly Polish choice for this dish.
Why is bread soaked in milk instead of using breadcrumbs?
Soaked bread creates a more tender, moist meatball texture than dry breadcrumbs, which can make the meatballs denser — this technique is standard across many Central and Eastern European meatball traditions.
Can I make the gravy without sour cream?
Yes, the gravy is still flavorful without it, though the sour cream adds a subtle tang and richness that's a common addition in many Polish households — you can substitute plain yogurt if needed.
