Leftover Chinese Roast Duck Noodle Soup

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 got tons of flavours to offer and I’m not about to waste it. So I kept all of that and made a homemade duck broth, and then turned it into this Leftover Chinese Roast Duck Noodle Soup.

How to make leftover roast duck noodle soup

I’ve always loved roast duck noodle soup. That’s why this is the first leftover recipe idea that popped in my head after I put my roast duck meal kit order in.

The leftover bones and carcass are perfect to make a tasty broth for your noodle soup, so don’t be so quick to throw them away. There are so much essence and flavours in the bones that are too good to waste. In addition, bone broths are known to carry high nutrition values and are particularly known to carry a high amount of collagen.

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 flavours out of them. I’ve used star anise, onions, fresh ginger and garlic in it as well to flavour it. 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 with soy sauce and let it cooked for just 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.

Noodles & toppings

I used La Mian and topped it with British pak choi, leftover roast duck leg, a sprinkle of chopped spring onions and a drizzle of chilli oil.

Here are some alternatives that would work well with the roast duck noodle soup.

  • Noodles options: egg noodles, rice vermicelli, rice noodles, la mian
  • Vegetable options: British pak choi, Chinese bok choi, kai lan (Chinese broccoli), choi sum, Chinese Napa Cabbage

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?
