Roasted Bone Marrow with Citrus Gremolata

Bone marrow is the dish that separates people who eat from people who cook. It's pure fat, roasted in its own bone until it goes soft and jiggly, and you spread it on toast like the richest butter you've ever tasted. Most people have only had it at restaurants. It costs almost nothing to make at home.

I got hooked on marrow at a place in Chicago that served it with a citrus salad on top. The acid and the brightness cut through all that richness and made it feel like you could eat the whole plate without hitting a wall. That's what this recipe does.

Ingredients

The Marrow

• 4 center-cut marrow bones, split lengthwise (ask your butcher)
• Flaky salt
• Coarsely ground black pepper

Citrus Gremolata

• 1 cup flat-leaf parsley, finely chopped
• 1 small shallot, minced
• Zest and segments of 1 navel orange
• Zest of 1 lemon
• 1 tablespoon capers, chopped
• 2 tablespoons good olive oil
• Pinch of red pepper flake

Garnish

• Watermelon radish, sliced paper thin
• Microgreens
• Grilled sourdough or country bread

The Cook

Soak the Bones

Soak the marrow bones in cold salted water for 12-24 hours in the fridge, changing the water a few times. This draws out the blood and impurities. The marrow should look creamy white when you're done.

Roast

Preheat your oven to 450F. Place the bones cut-side up on a sheet pan. Season with salt and pepper. Roast for 15-20 minutes until the marrow is soft, slightly bubbling at the edges, and starting to pull away from the bone. You want it jiggly, not melted. If you go too long, you lose it all into the pan.

While It Roasts

Make the gremolata. Toss the parsley, shallot, orange segments, both zests, capers, olive oil, and red pepper flake together. Season with a pinch of salt. This should be bright and punchy. It's doing all the heavy lifting against the richness of the marrow.

Grill or toast thick slices of sourdough until they have char marks and structure. You need bread that can hold up to being loaded with marrow.

Plate

Pull the bones from the oven. Set them on a platter or individual plates. Pile the citrus gremolata on top. Lay thin slices of watermelon radish over and around. Scatter microgreens. Serve with the grilled bread on the side.

Spread the marrow on the toast, top with a forkful of the gremolata. The contrast between the rich, fatty marrow and the bright, acidic salad is the whole point.
