Instructions
8 steps- 1
Pound each slice of beef between plastic wrap to an even 1/4 inch thickness, then season both sides with salt and pepper.
- 2
Melt half the butter in a skillet and saute half the chopped onion with the mushrooms until the liquid released has evaporated and the mixture is golden, about 8 minutes; let cool slightly.
- 3
Stir the chopped hard-boiled eggs into the cooled mushroom mixture.
- 4
Spread a spoonful of the filling along one edge of each beef slice, roll up tightly, and secure with kitchen twine or a toothpick.
- 5
Heat the remaining butter in a heavy pot and brown the rolls on all sides over medium-high heat, then remove.
- 6
Add the remaining onion to the pot and cook until soft, sprinkle in the flour, and stir for a minute before whisking in the beef broth.
- 7
Return the rolls to the pot, cover, and braise over low heat for 45 minutes to an hour, until fork-tender.
- 8
Stir the sour cream into the pan sauce, remove the twine or toothpicks, and serve the zrazy napped with the sauce.

Cultural context
Zrazy are Polish beef roulades — thin slices of beef wrapped around a filling of bacon, pickles, and mustard, then browned and braised in a rich brown gravy until tender. The dish has direct parallels in German rouladen and Russian zrazy otbivnye, but the Polish version is distinguished by the use of dill pickle and prepared mustard inside the roll, which contribute bright acidity to an otherwise deeply savory braise. Zrazy appear in the earliest Polish cookbooks of the 17th century, testament to their long history as a festive beef preparation for occasions that called for something more elaborate than a simple pot roast.
Listahan note
This version keeps the filling to three ingredients — mustard, bacon, and dill pickle — because anything more complicated crowds out the clean, tangy contrast those three create against the beef and the rich braising sauce.
Technique cues
- Pound the beef slices to an even quarter-inch thickness before filling; uneven thickness means some sections cook through before others, and a thick center will not braise tender in the time the thinner edges need.
- Sear the rolls in a very hot pan until deeply browned on all sides before adding the liquid — the fond from searing is what gives the gravy its brown, complex base and no amount of braising time compensates for skipping it.
- Braise over the lowest heat possible and resist lifting the lid frequently; a long, undisturbed braise in tightly sealed conditions is what allows the tough beef to fully relax and the filling flavors to meld into the meat.
Kitchen flow
- Parallel prep
- Pound all the beef slices and have the filling components laid out in a row before starting assembly so rolling proceeds quickly and the meat does not dry out from exposure.
- Make-ahead
- Zrazy are a genuine make-ahead dish — assembled raw rolls can be refrigerated overnight before searing, or finished braised rolls keep in their gravy refrigerated for 3 days and improve considerably.
- Leftover move
- Slice cold leftover zrazy thin and serve on rye bread with mustard and pickles for an open-faced sandwich that makes excellent use of the chilled roulade format.
- Cleanup rhythm
- Secure rolls with toothpicks before searing and count them so you can confirm all are removed before serving; sear in two batches if needed to avoid crowding the pan.
Ingredient brief
Role, handling, and swap guidance for each key ingredient.
beef top round or flank steak
primary protein wrapper
Purpose: Thin-sliced round or flank has the right size and texture for rolling and benefits from the long braise that tenderizes the tougher muscle fibers.
Handling: Place between sheets of plastic wrap and pound to a uniform quarter-inch thickness; cut into roughly 4x6-inch rectangles for rolling.
Adaptation: Beef sirloin or bottom round works well; avoid tenderloin as it is too tender to withstand the long braise and will become mushy.
Polish dill pickles
filling acidic component
Purpose: Dill pickle inside the roll contributes a vinegary tang that cuts through the richness of the beef and bacon during the long braise, preventing the dish from feeling heavy.
Handling: Cut into thin spears or julienne strips that lie flat inside the roll without creating a thick bump that prevents tight rolling.
Adaptation: Cornichons work well for a smaller, more intense burst of acidity; any dill brine-cured pickle works, but avoid sweet pickles.
smoked bacon
filling fat and smoke
Purpose: Strips of smoked bacon inside the roll melt into the beef during braising and contribute smokiness and fat that bastes the interior without any extra effort.
Handling: Use thin-cut strips and lay flat without overlapping inside the rolled beef; thick-cut bacon does not cook fully inside the roll during the braise.
Adaptation: Smoked ham slices or even speck work in place of bacon if you want a slightly less fatty filling with similar smokiness.
Dijon or Polish mustard
filling binder and flavor base
Purpose: Spread directly on the beef before layering the filling, mustard acts as a barrier that holds the filling in place and adds pungency that complements the pickle's tang.
Handling: Spread a thin, even coat on the pounded beef surface — too much mustard creates a thick layer that prevents the filling from adhering to the beef as it rolls.
Adaptation: Horseradish cream is a traditional Polish alternative that provides a sharper, more aggressive heat than mustard if you prefer a bolder filling.
beef stock
braising liquid
Purpose: A rich beef stock braising liquid concentrates during cooking into the deep brown gravy that is as important to the dish as the roulades themselves.
Handling: Heat before adding to the seared rolls so the temperature stays high and the braise begins immediately rather than requiring time to come back to a simmer.
Adaptation: A combination of beef stock and a small amount of red wine produces a more complex, restaurant-style gravy with additional depth.
Technique notes
- Tying the rolls with butcher's twine produces a more secure and uniform result than toothpicks, especially for larger rolls — use two ties per roll spaced an inch from each end.
- Deglaze the searing pan with a cup of beef stock and scrape every bit of browned fond before adding the rolls back; the fond contains the concentrated flavor that elevates the braising liquid from thin to deep-tasting.
- Thicken the finished braising liquid by removing the rolls, whisking in a beurre manie (equal parts soft butter and flour mashed together), and simmering for 5 minutes until the gravy reaches a coating consistency.
Ingredient swaps
- Gluten-free direction
- Thicken the finished braising sauce with cornstarch slurry (1 tablespoon cornstarch dissolved in 2 tablespoons cold water) rather than beurre manie for a gluten-free gravy.
- Dairy-free direction
- The filling and braise are beef, pickles, bacon, mustard, and beef stock — no dairy ingredient in that list; mustard and stock brands vary, so check the label for your household's own allergens.
- Weeknight shortcut
- Braise zrazy in a pressure cooker for 25 minutes at high pressure instead of the 90-minute stovetop braise; the result is equally tender with a quarter of the cooking time.
Serve alongside
- buckwheat kasha with butter
- mashed potatoes for sauce absorption
- braised red cabbage
- dry Polish red wine
- dark lager or porter
Serving suggestions only — check pairings for your household's allergens.
Storage & reheating
- Zrazy keep refrigerated in their braising gravy for up to 4 days; the flavors improve overnight as the filling continues to meld with the beef. Reheat gently in a covered pan over low heat. The finished dish freezes well in its gravy for up to 3 months; thaw overnight in the refrigerator before reheating.
Equipment
- meat mallet or rolling pin for pounding the beef
- toothpicks or butcher's twine for securing rolls
- Dutch oven or heavy braising pot with a tight lid
