How to make Buttermilk Lemon Garlic Roast Chicken

Making a whole roast chicken is really not as daunting as one might think. This Lemon Garlic Roast Chicken Recipe could be a good starting point! Simply follow the steps and tips I’ve got for you below and you’d be a pro at this in no time.

Marinating the Chicken

Always, always marinate the chicken.

Generous amount of salt and black pepper is a must. Here I have created a spice rub using Paprika, Chilli Powder, Garlic Powder, and Harissa Spice Powder. Mix all of them together and rub all over the chicken.

Then place the chicken in a large bowl or large ziplock bag with Buttermilk. Let marinate overnight.

If you don’t have buttermilk, worry not. Read how to easily make your buttermilk at home below under the common FAQ section.

Stuffing the Chicken with Lemon, Garlic and Onions

Stuffing the chicken cavity helps to enhance the flavours of the roast chicken. In this recipe, I have 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.

Just right before you stuff the lemon into the chicken though, I’ve got one trick here for you below.

How to Make a Juicy Roast Chicken – the Secret Trick

Buttermilk does part of the job but I have another secret to turn your roast chicken extra juicy, if not the juiciest.

I actually learnt this trick from Halal Girl About Town, which involves creating a compound butter and stuffing it underneath the skin! It’s a small extra step but one that’s totally worth it and a game-changer.

To make the compound butter, simply whip together butter, garlic paste, black pepper, chopped fresh coriander leaves, lemon zest, lemon juice, and olive oil. You can obtain the lemon zest and lemon juice from the lemon you were going to stuff into the chicken cavity. Extra extra tip here: to add more flavour to it, substitute the olive oil with animal fat. I used duck fat and the results were dreamy.

Then it’s simply about getting your hands dirty and stuffing the butter underneath the skin. You can also use the back of a spoon to help you with it.

I also like to score the drumstick parts before marinating the chicken and also stuff some of that compound butter through the opening of the pierced skin from scoring. The drumsticks tasted absolutely ridiculously tasty and succulent.

Leave roughly half a tablespoon of the compound butter to save it for basting the chicken at latter stages of cooking. It will help you to get the perfect colour for the roast chicken.

Need proof when I say it’s going to be the juiciest roast chicken? Just take a look for yourself in this video and see how much juices ooze out of it!

Roasting the Vegetables Beneath the Chicken

Lay the roast vegetables of your choice on a roasting tin. Roughly season with salt and black pepper, and toss with a tablespoon of olive oil (or animal fat). Then place a grill rack over the tin and the chicken on top. And off they go into the oven together and let the magic happen.

Essentially, what you want to do here is to let the dripping juices from the chicken to flavour the vegetables. With this roast chicken recipe, you’re going to get a lemon-y flavour roast vegetables.

I’ve used carrots and broccoli as pictured. Why not also try out the likes of parsnips, aubergine, zucchini, etc.!

Cooking the Roast

Preheat the oven to 180°C. Place the roast into the middle of the oven and cook for about 50 minutes.

Then use the remaining compound butter to bast the chicken by brushing it all over the chicken. This would give the chicken a nice golden touch of colour.

Turn up the temperature to 200°C and cook for another 10 minutes to let the skin turn golden brown in colour. Check to ensure the internal temperature reaches 75°C before you remove it from the oven.

Let the chicken rest for about 5 minutes before serving.

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 one would be making a chicken sandwich for the next day. I made mine with shredded leftover roast chicken and some Air Fried Maple Glazed Turkey Rashers plus a spread of Kewpie mayo.

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. That could work either.

As for the remaining carcass, you can make a chicken bone broth out of it. I even took a step further and made it into a creamy Japanese Paitan Ramen Broth! Stay tuned for my recipe for it, it’s a lengthy process but it tasted so amazing.
