Classic Duck Confit w/ Crispy Potatoes, Fresh Corn Polenta, and Charred Grape Agrodolce

Duck legs cured in green salt, slow-cooked in duck fat until silky tender, and crisped golden. Served over creamy fresh corn polenta with duck-fat roasted potatoes and a charred grape agrodolce.

Why You'll Love This Recipe

The green salt cure (kosher salt, parsley, and black pepper pulsed together) sits on the legs for 24 to 48 hours before they cook submerged in duck fat at 250°F for 2.5 to 3 hours, until the meat is silky and pierces easily with a knife. A final crisp in a hot skillet or under the broiler brings the skin back to crackling. The corn polenta is just grated corn purée cooked in butter until it sets, and the charred grape agrodolce, honey darkened in the pan then grapes charred cut-side down and deglazed with red wine vinegar and chicken stock, is what cuts through the richness.

Tips and Tricks

• Pat the duck completely dry before crisping - any moisture will prevent the skin from crackling.
• Let honey darken slightly before adding grapes; the caramelization adds depth to the agrodolce.
• Always crisp the duck just before plating so the skin arrives at the table at peak crunch.
• The cast iron holds heat evenly for both the polenta and the agrodolce - use it for both components.

Variations

• Swap corn polenta for celery root purée in colder months.
• Add orange zest to the agrodolce for a citrus lift.
• Use black grapes for a deeper, jammy flavor.

Substitutions

• Butter in polenta → olive oil.
• Red wine vinegar → sherry vinegar.
• Basil and tarragon → mint and parsley.
• Pee-wee potatoes → fingerling or baby Yukon Golds.

Best served with

• Charred broccolini
• Aged balsamic roasted carrots
• A crisp white Burgundy

How to Store Leftovers

Store duck submerged in strained duck fat in an airtight container in the refrigerator for up to 2 weeks. Potatoes, polenta, and agrodolce are best eaten fresh but can be refrigerated separately for up to 2 days. Reheat polenta gently over low heat with a splash of water or butter. Re-crisp duck skin in a hot skillet before serving.

Notes
