How to Make
1. Prepare the Bones
1️⃣ Preheat oven to 450°F.
2️⃣ Place marrow bones cut-side up on a baking sheet lined with parchment or foil.
3️⃣ Season generously with sea salt and black pepper.
2. Roast
1️⃣ Roast for 15–18 minutes, until the marrow is bubbling, glossy, and soft like custard.
2️⃣ Do not overcook — the marrow should be silky, not melted away.
3. Meanwhile, Make the Gremolata
1️⃣ In a small bowl, mix parsley, rosemary, garlic, lemon zest, olive oil, and flaky salt.
2️⃣ Taste and adjust — it should be fresh and aromatic, not heavy.
4. Serve
1️⃣ Spoon gremolata generously over hot marrow.
2️⃣ Serve immediately with keto sides or eat straight from the bone (chef’s privilege).
