Recipe Notes

How to make buttermilk at home

Buttermilk is one of the best marinades for chicken. For every cup of milk, mix with a tablespoon of lemon juice or vinegar. Let it sit for about 5 minutes until tiny curdles begin to form. Et voilà! That’s your homemade buttermilk and can be used as required.

Stuff the chicken for extra flavours

Stuffing the chicken cavity helps to enhance the flavours of the roast chicken. In this recipe, I stuffed the chicken with lemon, onions, and garlic. The flavours of these ingredients will then infuse into the chicken throughout the cooking process and help to spread the flavours through the meat. Not only does the lemon plays the role of a flavour enhancer, but it also helps to moisten the chicken, keeping the meat juicy. You can also add in a handful of fresh herbs to the stuffing as well.

Compound butter is the secret trick to making the juiciest roast chicken

You do not want to miss out on this one simple step. It is a real game-changer in making the juiciest roast chicken. Feel free to try different flavour combos but I went with a classic lemon garlic compound butter and stuff it underneath the chicken skin. You’ll have to get your hands dirty for this but it’d be so worth it!

Other than stuffing the compound butter under the skin, you can also use it to brush all over the chicken mid-way through the cooking process. This helps to get the perfect golden touch of colour for the roast chicken!

Make sure the internal temperature reaches 75°C

Check the internal temperature of the chicken by using a cooking thermometer. Simply insert it into the thickest part of the chicken, without touching the bones, to check whether your chicken is fully cooked or not. The chicken is safe to consume when its internal temperature reaches 75°C.

What to Do with Leftover Roast Chicken

There are lots of ideas to play around with for any leftover chicken, including the carcass! The most straightforward leftover idea would be making a chicken sandwich for the next day. You can also turn it into a comforting bowl of Lemon Chicken Pasta Soup – something light and healthy, or toss it with your regular pasta dishes.

As for the remaining carcass, you can make a lovely chicken broth out of it. If you’re up for a challenge, you can even turn it into a creamy Japanese Paitan Ramen Broth (this involves cooking the carcass & bones till softened and blending them all into a rich broth)!
