I never would’ve thought I would be roasting a whole duck at home, but the Rice Guys made it happen with their halal Cantonese Roast Duck meal kit! And oh my, was that so ridiculously good. We started by tackling the duck for a Peking Duck style, i.e. with Mandarin pancakes, sliced scallions, and Hoisin sauce. Then we carved out all the remaining meat and saved it for leftovers. All that’s left now is the bones and carcass of that beautiful duck, which clearly still has tons of flavours to offer, and I’m not about to waste it. So I kept all that and made a homemade duck broth, then turned it into this gorgeously delicious Leftover Chinese Roast Duck Noodle Soup.
Why You’ll Love This Chinese Roast Duck Noodle Soup
You’ve got to love a zero-waste recipe! The bones and carcass still contain plenty of flavour and essence that are too good to be wasted. They make a fantastic base for a homemade broth. Simply throw in some basic aromatics like ginger, garlic, onion, and star anise, and you’ll have a beautifully rich and savoury broth that’s perfect for pairing with noodles and vegetables. It turns yesterday’s roast duck into an entirely different meal. In addition, bone broths are known to be highly nutritious and are particularly known to contain a high amount of collagen.

Cooking Tips & Recipe Notes
Making a broth with leftover bones
Similar to making a chicken or beef bone broth, you dump all the leftover duck bones and carcass into a large pot of water and cook for hours until you’ve extracted every ounce of flavour out of them. I’ve used star anise, onions, fresh ginger and garlic in this recipe for flavouring. I did the first taste test at around the four-hour mark, and the flavours were delicious! Of course, the longer you cook it, the richer the flavour.
Seasoning-wise, I seasoned it with a dash of soy sauce and let it cook for a little longer for the flavours to get through. Last but not least, I served it as a noodle soup with toppings of your choice.
How to reheat leftover roast duck
Reheat the Roast Duck in an Air Fryer! The skin will come out super crispy and the meat so juicy as if it’s just freshly roasted. Place the roast duck onto the air fryer basket and cook for 5 minutes at 180C.

If I use frozen bones, can I then freeze the stock?
