Method

  1. Season and sear the beef shanks; braise with vegetables, wine, stock, Worcestershire, and herbs at 325°F for 3–4 hours.

  2. Shred the meat, reserve marrow, and reduce the braising liquid; combine with the shredded beef.

  3. Prepare bone‑marrow cream by mixing marrow with sour cream, mustard, lemon juice, and optional horseradish.

  4. Mix chimichurri ingredients together.

  5. Soak onion slices in buttermilk, coat with flour‑cornstarch mix, and fry at 350°F until golden; salt immediately.

  6. Toast buttered rolls, spread marrow‑cream, add beef and provolone, broil to melt cheese, then top with chimichurri and onion strings.

Tips while you cook

Reserve braising liquid
After braising, strain and reduce the liquid, then toss the shredded beef back in.
Buttermilk soak for onions
Soak thinly sliced onion in buttermilk for 20 minutes before coating.
Broil cheese just before serving
Place provolone on the assembled sandwich and broil briefly to melt the cheese before adding chimichurri.
Season onion strings immediately
Salt the fried onion strings right after they come out of the oil for best flavor.
