Roasted Bone Marrow with Parsley Salad

Jump to Recipe

Bone marrow is one of those ingredients that looks dramatic on the plate but asks very little of you in the kitchen. You salt the bones, roast them hard and fast, and they’re done in under 20 minutes.

The parsley salad is the part people often skip, and that’s a mistake. The combination of flat-leaf parsley, capers, shallot, and lemon does real work here – it stops the marrow from tasting one-note and heavy.

This is a starter that works for a dinner party or a quiet Tuesday night when you want something different. The bones are inexpensive and the whole dish comes together in about 40 minutes from fridge to table.

Grilled sourdough is not optional. You need something sturdy to scoop the marrow, and the char on the bread adds a bitter note that ties everything together.

Why You’ll Love This Recipe

• Rich marrow ready in under 20 minutes of roasting
• Parsley salad keeps each bite sharp and balanced
• Inexpensive cut that looks impressive on the table
• Gluten-free if you swap in GF bread for serving

Ingredient Notes

• beef femur bones: Ask your butcher to cut them lengthwise (canoe-cut) for easy access to the marrow. Cross-cut rounds work but are harder to scoop cleanly.
• flat-leaf parsley: Curly parsley is too bitter and too tough here. Use flat-leaf only, and pick the leaves from the stems – stems add woody texture.
• capers: Salt-packed capers rinsed and chopped give the best texture. Brine-packed capers work fine – just drain them well before using.
• shallot: Slice thin and soak in the lemon juice for 5 minutes before mixing the salad – this softens the raw bite without losing the crunch.
• sourdough bread: A dense, open-crumb sourdough holds up to the marrow without going soggy. Any sturdy country loaf works as a substitute.
• flaky sea salt: Maldon or fleur de sel on the finished marrow is not decorative – the crunch and hit of salt on each spoonful matters.

Ingredients

  

For the bones

• 8 halves (about 1.2 kg total) beef femur bones, canoe-cut lengthwise ask your butcher to cut them lengthwise
• 1 tsp flaky sea salt for seasoning before roasting
• 1/2 tsp freshly ground black pepper

For the parsley salad

• 30 g flat-leaf parsley leaves, picked about 1 large bunch
• 1 small shallot, thinly sliced
• 2 tbsp capers, rinsed and roughly chopped salt-packed or brine-packed, both work
• 2 tbsp fresh lemon juice
• 2 tbsp extra-virgin olive oil
• pinch flaky sea salt to taste
• pinch freshly ground black pepper

For serving

• 8 slices sourdough bread, sliced 1.5 cm thick or any sturdy country loaf
• 1 tbsp extra-virgin olive oil for brushing the bread
• to taste flaky sea salt for finishing at the table

Method

 

Prep the bones

1. If you have time, submerge the cut bones in a large bowl of cold, lightly salted water and refrigerate for 12 to 24 hours, changing the water once. This draws out blood and produces a cleaner marrow. Drain and pat the bones completely dry before roasting.
2. Heat the oven to 220 C / 425 F. Place the bones cut-side up in a single layer on a rimmed sheet pan or in a cast iron skillet. Season the exposed marrow with flaky salt and black pepper.

Roast the bones

1. Roast on the center rack for 15 to 18 minutes, until the marrow is soft, just beginning to bubble at the surface, and pulling slightly away from the bone edges. Check at the 15-minute mark - you want the marrow set but not liquefied.
2. Remove from the oven and rest for 2 minutes before serving.

Make the parsley salad

1. While the bones roast, combine the thinly sliced shallot and lemon juice in a small bowl. Let it sit for 5 minutes to soften the raw shallot bite.
2. Add the parsley leaves, chopped capers, and olive oil. Toss gently to coat. Season with a pinch of salt and black pepper. Do not dress the salad more than 5 minutes before serving.

Grill the bread

1. Brush the sourdough slices on both sides with olive oil. Heat a grill pan over high heat until smoking, then grill the bread for 1 to 2 minutes per side until char marks form and the surface is crisp. Alternatively, use the broiler set to high, placing the bread on the top rack for 2 minutes per side.

Serve

1. Arrange the roasted bone halves on a warm board or plate, cut-side up. Pile the parsley salad alongside. Finish the marrow with a pinch of flaky sea salt at the table. Serve immediately with the grilled sourdough and small marrow spoons or narrow teaspoons for scooping.

Notes

If your butcher only has cross-cut round bones, increase roasting time by 3 to 4 minutes and use a narrow espresso spoon to scoop the marrow cleanly from the cylinder.

Tips for Success

• Soak the cut bones in cold salted water for 12 to 24 hours to draw out blood and produce a cleaner, paler marrow.
• Pat the bones completely dry before roasting so the marrow surface browns lightly rather than steaming.
• Watch the oven at the 15-minute mark – marrow that runs out and pools on the pan is overcooked and loses half its richness.
• Dress the parsley salad no more than 5 minutes before serving so the leaves stay crisp rather than wilting from the lemon.
• Rest the roasted bones for 2 minutes before serving – marrow fresh from the oven is too hot to taste properly.

Variations

• Add finely grated fresh horseradish to the parsley salad for a sharper, more peppery contrast against the marrow.
• Swap capers for finely chopped cornichons and a teaspoon of whole-grain mustard in the salad dressing.
• Top the marrow with a small pile of pickled red onion and fresh dill instead of the classic parsley salad.

Storage and Reheating

Roasted bone marrow is best eaten within 15 minutes of coming out of the oven. Once cooled, the marrow solidifies back to fat and the texture is not the same after reheating.

If you have leftovers, scoop the cooled marrow into a small jar, cover with a layer of plastic wrap pressed to the surface, and refrigerate for up to 3 days. Use it as a spread on toast or stir a spoonful into mashed potatoes.

To reheat, place the bones upright in a 220 C / 425 F oven for 8 to 10 minutes until just softened again. Do not microwave – it splatters and overheats unevenly.

Serving Suggestions

Serve the bones on a wooden board or directly on a warm plate with the parsley salad piled alongside and thick slices of grilled sourdough. Put out small marrow spoons or narrow teaspoons so guests can scoop cleanly from the bone.

A simple green salad with sharp dressing works well after the marrow course to reset the palate. The richness of the dish means a small portion satisfies – two bone halves per person is typically enough as a starter.

For a more substantial plate, add a soft-boiled egg halved on the board and a handful of watercress dressed with lemon and olive oil. A glass of light, high-acid red wine like Barbera or Beaujolais cuts through the fat without overpowering the dish.

FAQ

How do I know when the bone marrow is done roasting and not overcooked?

The marrow should be soft, slightly pulling away from the bone edges, and just beginning to bubble at the surface – usually at the 15 to 18 minute mark at 220 C. If you see a significant pool of clear fat in the pan, the marrow has melted out and is overdone. A thin probe or skewer inserted into the center should meet no resistance.

Can I use cross-cut bones instead of lengthwise canoe-cut bones for this recipe?

Yes, cross-cut rounds work but you’ll need a narrower spoon to scoop the marrow out after roasting. Canoe-cut bones are easier for guests to access and give a better surface area for seasoning.

Can I prep the parsley salad the night before and keep it in the fridge?

Prep the components – washed parsley leaves, sliced shallot, rinsed capers – separately and refrigerate them. Don’t dress the salad until just before the bones come out of the oven, or the parsley will go limp and lose its texture.

Is roasted bone marrow gluten-free?

The marrow and parsley salad are naturally gluten-free. The dish only contains gluten if you serve it with regular sourdough or wheat bread – swap in a gluten-free country loaf or rice crackers to keep the whole plate gluten-free.

What is the difference between roasted bone marrow and the version served at St. John restaurant in London?

The St. John version made this dish famous in the 1990s and uses the same basic format – canoe-cut roasted femur bones with a flat-leaf parsley salad, capers, and toast. The main difference is their salad uses a small amount of shallot and a light dressing of olive oil and lemon with no garlic. Home versions often add extra acid or garnish, but the St. John approach is stripped back by design.

What wine pairs well with roasted bone marrow?

A high-acid, lighter-bodied red like Barbera d’Asti or Beaujolais works well because the acidity mirrors the job the parsley salad does – cutting the fat cleanly. If you prefer white, a mineral Chablis or unoaked Chardonnay also holds up without adding more richness.
