Preheat your oven to 475°F (245°C) with a heavy rimmed baking sheet or cast-iron skillet placed on the middle rack so it gets hot. Pat the marrow bones dry with paper towels to remove any excess moisture or fragments. Using a small spoon or knife, scrape away any loose marrow that is hanging out of the cut edge to create a neat surface.

Season the marrow side lightly with kosher salt and freshly ground black pepper. Drizzle or brush about 1 tablespoon olive oil on the exposed marrow surfaces to promote browning and prevent sticking.

When the oven and baking surface are fully preheated (10–15 minutes), arrange the bones marrow-side up on the hot sheet/skillet so they sit snugly and won’t tip. Roast for 12–15 minutes, watching for the marrow to bubble and the edges to become golden and slightly blistered. Do not overcook — marrow should be soft and glossy but not completely liquefied.

If you prefer a slight char and smoky finish, switch the oven to broil for the last 1–2 minutes, keeping the door ajar and watching carefully to prevent burning.

Remove the bones from the oven and let them rest on the pan for 1–2 minutes. Sprinkle a pinch of coarse cracked black pepper if using. Keep warm while you finish the gremolata and toast the bread.

Herb Gremolata

While the bones roast, make the gremolata. Combine the finely chopped flat-leaf parsley, minced garlic, minced anchovy (if using), and reserved tender parsley stems in a small bowl.

Add the lemon zest, lemon juice, 1 teaspoon extra-virgin olive oil, sea salt, and freshly ground black pepper. Stir thoroughly to combine. Taste and adjust seasoning — the gremolata should be bright, slightly salty, and vivid to cut through the marrow’s richness.

Set the gremolata aside at room temperature so the flavors meld and the garlic slightly softens from the residual heat of the roasted bones when served.

To Serve

Toast or grill the bread slices until crisp and golden. Rub the warm toasted bread lightly with a cut garlic clove (optional) to impart a subtle garlic note.

Place two roasted bone halves per person on a warmed plate or share platter. Spoon a generous teaspoon of gremolata over each exposed marrow cavity (or serve the gremolata in a small bowl to allow guests to add to taste).

Serve each portion with a slice of toasted bread to spread the warm marrow onto. Offer lemon wedges and optional cornichons or pickled shallots to provide acidity alongside microgreens or chives for freshness.

To eat: use a small spoon or a bone spreader to scoop the marrow onto the toast, top with a little gremolata, and finish with a squeeze of lemon if desired.
