Duck Recipe UK: Crispy Roast Duck with Orange Gravy

This UK-style roast duck has crisp, deeply browned skin and tender meat, served with a simple orange gravy made from the roasting juices. It makes a generous Sunday-style centrepiece, and the method helps render excess fat while keeping the bird flavourful.

Ingredients

1 whole duck, about 5 lb (2.3 kg), giblets removed
2 tsp (10 g) kosher salt, or 1½ tsp (8 g) fine salt
1 tsp (2 g) freshly ground black pepper
2 medium oranges, about 10½ oz (300 g) total
1 medium onion, about 5 oz (150 g), peeled and quartered
2 garlic cloves (about 6 g), lightly crushed
4 fresh thyme sprigs (about 4 g), or 1 tsp (1 g) dried thyme
1 cup (240 ml) water, for the roasting pan
1 tbsp (15 g) rendered duck fat from the pan, or unsalted butter
2 tbsp (16 g) plain all-purpose flour
1 cup (240 ml) low-salt chicken or duck stock
⅓ cup (80 ml) fresh orange juice, squeezed from one of the oranges
1 tsp (5 ml) cider vinegar
1 tsp (7 g) honey, optional

Instructions

Prepare the duck. Take the duck from the refrigerator about 20 minutes before it goes into the oven, while you prepare the other ingredients. Heat the oven to 425°F (220°C). Remove any giblets from the cavity, trim away large loose pieces of fat near the opening and pat the duck thoroughly dry with paper towels. Dry skin browns more readily than damp skin. Prick the skin all over the breast and thighs with the tip of a sharp knife, spacing the holes about 1 inch (2.5 cm) apart. Aim to pierce the skin and fat only, not the meat; this gives rendered fat a way to escape without drying the flesh.
Season and fill the cavity loosely. Rub the salt and pepper over the skin and a little inside the cavity. Cut one orange into quarters and place it loosely inside the duck with the onion, garlic and thyme. Do not pack the cavity tightly, because air needs to circulate for even cooking. Put the duck breast-side up on a rack set inside a sturdy roasting tin. Pour 1 cup (240 ml) water into the tin beneath the rack, taking care not to pour it over the duck. The water helps stop early drippings from scorching; it will evaporate during roasting.
Start roasting at high heat. Roast at 425°F (220°C) for 20 minutes to begin browning the skin. Carefully remove the tin from the oven and pour off the liquid fat into a heatproof bowl, using oven gloves and taking care not to splash yourself. Keep the duck on its rack. The first fat may be mixed with water, so let it settle and separate before saving the clear fat.
Lower the heat and roast until cooked through. Reduce the oven to 350°F (180°C) and roast for about 1 hour 50 minutes more. Every 40–45 minutes, check the roasting tin and carefully pour off excess fat so it does not smoke or spill. If the pan becomes dry, add a small splash of water to the tin beneath the rack. Cooking time is an estimate: the bird’s shape and your oven can affect it. Check with a food thermometer in the thickest part of the breast and the inner thigh, without touching bone. The USDA FSIS safe minimum internal temperature for duck and other poultry is 165°F (74°C); if either spot is below that, continue roasting and check again after 10–15 minutes.
Rest the duck. Transfer the cooked duck to a carving board and leave it uncovered for 20 minutes before carving. Resting lets the juices settle and gives you time to finish the gravy. If the skin softens a little as it rests, that is normal; carve with a sharp knife and serve the crispest pieces on top. Strain the roasting juices into a heatproof jug, leave them briefly so the fat rises, then spoon off most of the fat. Keep about 1 tablespoon (15 g) for the gravy.
Make the orange gravy. While the duck rests, zest the second orange and squeeze out ⅓ cup (80 ml) juice. In a small saucepan over medium heat, warm 1 tablespoon (15 g) duck fat. Stir in the flour and cook for about 1 minute, stirring continuously, until it forms a smooth paste and smells lightly toasted. Gradually whisk in the stock, orange juice and strained roasting juices. Bring to a gentle simmer and cook for 5–8 minutes, whisking often, until glossy and thick enough to coat a spoon. Stir in the orange zest and cider vinegar; add honey if you prefer a softer, sweeter edge. Taste before adding salt, since the stock and pan juices may already be seasoned. Strain the gravy if you want it especially smooth.
Carve and serve. Remove the orange and onion from the cavity and discard them. Separate the legs from the body at the joints, then slice the breast meat across the grain. Arrange the meat on a warm platter and serve the gravy alongside rather than pouring it over all the skin. This keeps the skin crisp for longer at the table.

Tips

Dry the skin well. If you have time, pat the duck dry, place it uncovered on a tray in the refrigerator for 8–24 hours, then season just before roasting. This extra drying step is optional and is not included in the recipe’s stated timing. Keep raw poultry below ready-to-eat foods in the fridge, and wash hands and surfaces after handling it.
Prick carefully. Piercing only the skin helps release fat; puncturing the meat can let juices escape. If you notice a patch of skin that has not rendered, make a few small pricks there rather than deeply scoring the whole bird.
Manage the fat safely. Duck releases a substantial amount of hot fat. Pour it slowly into a stable heatproof container, never into the sink, and let it cool before refrigerating. Do not leave the roasting tin unattended if it begins to smoke; carefully lower the oven temperature and remove excess fat.
Adjust the gravy, not the roast. If the gravy is too thick, whisk in stock or water a tablespoon at a time. If it is thin, simmer it for a few more minutes. No duck stock? Chicken stock is an easy substitute; it makes the gravy a little less rich but still complements the orange and roasting juices.

Serving Suggestions

Serve the duck as a roast dinner with roast potatoes, carrots or parsnips, and a green vegetable such as peas, cabbage or Brussels sprouts. The orange gravy also works well with buttery mashed potatoes, which catch the juices without competing with the meat. A sharp, lightly dressed salad or pickled red cabbage can balance the richness of the duck, particularly if the meal includes several rich sides.

For a relaxed meal, put the carved duck on a platter and let everyone add gravy at the table. Keep any extra gravy warm over very low heat, stirring occasionally, or reheat it just before serving. If you are serving a smaller group, carve only what you need and keep the remaining meat in larger pieces; it is less likely to dry out while waiting.

Variations

Use a different citrus. Replace the orange juice with ⅓ cup (80 ml) apple juice and add 1 teaspoon (5 ml) cider vinegar for a gentler, less citrus-led gravy. Lemon juice is sharper, so start with 1 tablespoon (15 ml) and add more to taste rather than swapping it in cup for cup.

Add a British-style herb note. Swap the thyme for 2 fresh sage leaves (about 1 g) in the cavity, or add ½ teaspoon (1 g) dried sage to the gravy. Sage has a more assertive, savoury flavour, so avoid using a large handful. A pinch of ground ginger in the gravy is another option if you like a warm note with orange.

Make the gravy without pan juices. If the drippings are too salty or have scorched, leave them out and use 1¼ cups (300 ml) stock instead. Make the flour-and-fat base as directed, then whisk in the stock and orange juice. The sauce will be less roast-rich, but the orange zest and vinegar keep it bright.

Roast duck portions instead. Duck legs or breasts can be cooked separately, but they need different timing and should not simply be given the whole-bird schedule. Use a thermometer in the thickest part and follow the same poultry safety minimum of 165°F (74°C); check portions early because they cook faster than a whole bird.

Storage and Reheating

Refrigerate cooked duck within 2 hours of cooking. Remove the meat from the bones if you like, place it in a shallow airtight container and store it with the gravy separately; cooked duck keeps for 3–4 days in the refrigerator. Refrigerate the gravy in its own covered container. If the room is hot, do not leave the platter sitting out while people serve themselves for an extended period; pack leftovers promptly.

For longer storage, freeze the cooled meat and gravy in separate airtight containers for up to 3 months for best quality. Thaw them in the refrigerator, not on the counter. Reheat duck covered in a 325°F (165°C) oven with a spoonful of stock or water to help prevent drying, or warm small portions gently in a covered pan. Reheat leftovers to 165°F (74°C), checking the thickest pieces with a food thermometer. The skin will not stay as crisp after storage; for a little crunch, uncover the meat for the final few minutes of reheating, watching closely so it does not dry out.

Frequently Asked Questions

How much duck should I buy per person?

A whole duck weighing about 5 lb (2.3 kg) serves four people generously, with sides. A whole bird has bones and loses fat as it cooks, so it yields less meat than the same weight of boneless meat. For five diners or especially hearty appetites, choose a larger bird or plan an extra side dish.

Why prick the duck skin?

Pricking creates small openings through the skin so melted fat can drain into the roasting tin. Keep the holes shallow: if you pierce the meat, juices can escape and the finished duck may be drier. The rack also matters because it lets hot air circulate underneath rather than leaving the bird sitting in its fat.

Can I prepare the duck ahead?

Yes. You can pat it dry and leave it uncovered on a tray in the refrigerator for 8–24 hours before roasting, which also gives the surface time to dry. Keep it covered loosely if needed to prevent contact with other foods, and store it on the lowest shelf. Season immediately before cooking, and allow a little extra time if the bird is still very cold.

Is duck meant to be pink inside?

This recipe follows the USDA FSIS safe minimum for poultry, so check that both the thickest breast and inner thigh reach 165°F (74°C) with a thermometer. Colour alone is not a reliable way to judge safety, and meat near the bone can look darker even when cooked. If a reading is below the safe minimum, return the duck to the oven and check again.

Can I make the orange gravy without flour?

For a gluten-free option, use 1 tablespoon (8 g) cornstarch mixed with 2 tablespoons (30 ml) cold water instead of the flour. Bring the stock, juice and pan juices to a simmer, whisk in the slurry gradually and cook until thickened. The gravy will be glossier and slightly less creamy than a flour-based version; check that your stock is also gluten-free.

What should I do with leftover duck fat?

Let it cool until safe to handle, strain out any browned bits and refrigerate it in a clean, covered container. Use it for roasting potatoes or vegetables, where its savoury flavour is welcome. Discard it if it smells rancid or develops mould, and never pour liquid fat down the drain because it can solidify and block pipes.
