Roast lamb gets a fiery makeover with a bold jalapeño sauce, adding just the right amount of heat to shake up the traditional rosemary-and-garlic pairing. Recently put to the test at a family gathering, this dish was an undeniable hit.

The secret to this melt-in-your-mouth roast lies in slow cooking. Roasting the lamb at a lower temperature allows the meat to become tender. Basting throughout the cooking process helps lock in moisture, ensuring every bite is juicy.

And don’t rush to carve – letting the lamb rest for at least 10 minutes before slicing allows the juices to redistribute, making the final result even more succulent. Recipe compliments of Royco.

Ingredients

1 whole leg of lamb
15ml (1 Tbsp) salt
15ml (1 Tbsp) black pepper
15ml (1 Tbsp) cinnamon
15ml (1 Tbsp) dried garlic flakes
15ml (1 Tbsp) tomato pesto
1 x Royco Gravy for Roast Meat – use 3 Tbsp (45ml)
15ml (1 Tbsp) freshly squeezed lemon juice
15ml (1 Tbsp) honey
45ml (3 Tbsp) jalapeño sauce
fresh herbs, to garnish

Preheat your oven to 175° C.
Prepare the lamb: place the leg in a deep roasting tray and season generously with salt, pepper and cinnamon. Sprinkle over the garlic flakes, then coat the lamb with tomato pesto, ensuring it’s well covered.
Add the Royco flavour: sprinkle 3 Tbsp (45ml) of the powder from the sachet of Royco Gravy for Roast Meat over the lamb.
Drizzle the honey over the top of the lamb to add a touch of sweetness and help with caramelisation during roasting.
Roast the lamb: place the baking tray in the preheated oven and roast for about 3 hours, or until the lamb reaches an internal temperature of 70-75° C, or it is cooked to your liking. For more tender lamb, you can roast it for longer.
Five minutes before the lamb is done, remove the tray from the oven and rub the lamb with the jalapeño sauce for a spicy kick and a beautiful glaze. Return the lamb to the oven for the final 5 minutes.
Remove the lamb from the oven and let it rest for 10 minutes before slicing.
Garnish with fresh herbs and serve with any additional sauce from the pan.
