Stuffed Flank Steak with Marsala Mushroom Sauce

This is Italian Sunday-dinner cooking at its most showy. A butterflied flank steak gets a lavish stuffing of ground pork, pancetta, spinach, currants, and julienned provolone and carrot, then rolls up into a pinwheel that looks stunning when sliced. The marsala-porcini pan sauce takes it from impressive to unforgettable.

The stuffing is the star and deserves care. Browning the ground pork and pancetta first builds deep flavor in the base, and the currants are the secret that most cooks overlook. Those tiny sweet bursts against the savory meat are pure Italian grandmother logic, a classic Sicilian braciole touch borrowed from older Arab-influenced cuisine.

Julienned carrots and provolone placed lengthwise through the stuffing give you those gorgeous spiral patterns when you slice the finished roll. Lay them parallel to the grain of the meat; layering across the grain is how you end up with messy cuts instead of clean pinwheels.

Dry porcini soaked in hot water before adding to the sauce delivers depth no fresh mushroom can match. Save that soaking liquid and strain it through a coffee filter (to remove grit) into the pan sauce; it’s concentrated umami gold.

Cornstarch slurry at the end is an easier thickener than a roux when time is tight, but don’t overdo it. The sauce should coat a spoon, not stick to it like glue.

Slice on the bias and serve with soft polenta, risotto, or mashed potatoes.

Pro Tips

• Have your butcher butterfly the flank steak for you; it’s tricky to do evenly at home.
• Tie the rolled steak securely with kitchen twine at 1-inch intervals to keep the stuffing inside.
• Sear hard on all sides before braising for proper color and fond.
• Let the braciole rest 10 minutes before slicing so the juices redistribute.

Variations

• Swap currants for golden raisins or chopped dried cherries.
• Add toasted pine nuts to the stuffing for extra nutty crunch.
• Use madeira in place of marsala for a slightly drier, nuttier sauce.
