This slow-roasted spring lamb in herbs is a spectacular high-protein dish that celebrates the vibrant flavours of the season. By encasing a bone-in leg of lamb in a thick paste of preserved lemons, garlic, and toasted spices, the meat stays incredibly succulent while developing a deep, aromatic crust. The long, gentle roasting time ensures the lamb becomes meltingly tender, creating a rich jus that perfectly coats the accompanying baby potatoes.
Ideal for a Sunday lunch or a relaxed dinner party, this recipe is as much about the fresh finish as it is about the slow cook. Topping the shredded lamb with whole tarragon leaves and fresh dill adds a bright, zesty contrast to the savoury meat. Serve this impressive homemade meal in the centre of the table with plenty of lemon wedges for a healthy, crowd-pleasing feast.

2 small preserved lemons, skin and flesh chopped
4 garlic cloves, coarsely chopped
60ml extra-virgin olive oil, plus more for serving

How to make Spring Lamb in Herbs
Preheat oven to 163°C. Toast coriander and fennel seeds in a dry small skillet over medium-low heat, tossing occasionally, until very fragrant, about 2 minutes. Let cool.
Coarsely chop coriander leaves and tender stems (you’ll get about 2 cups) and transfer to a large bowl. Coarsely chop dill leaves and tender stems (you’ll get about 2 cups) and add to bowl with coriander. Pick leaves from tarragon bunches (do not chop; you’ll get about 160g ) and add to bowl; discard stems. Add spring onions and toss to combine. Transfer 475ml herb mixture to a small bowl, cover with a damp kitchen towel, and chill until ready to use. Transfer remaining herb mixture to a food processor. Add coriander and fennel seeds, preserved lemons, garlic, 60ml oil, and 2 teaspoons kosher salt. Purée until a paste forms.
Roll out a piece of foil that’s more than double the length of a rimmed baking sheet. Centre foil on baking sheet, then place lamb on foil. Rub lamb all over with herb paste. Bring up foil around lamb and wrap tightly to seal. Roast until lamb is super tender and is falling off the bone, 4–4 1/2 hours. (It’s important that you don’t open the foil packet once sealed. To check the meat, slide a skewer or small knife through the top of the foil; the meat should yield and shred easily.)
Meanwhile, place potatoes in a large pot. Pour in water to cover; season with salt. Cover pot and bring water to a boil. Cook until potatoes are tender, about 30 minutes. Drain, then transfer to a medium bowl.
Unwrap lamb (juices will run everywhere, so be careful to make sure they stay on the baking sheet) and let cool 20 minutes. Transfer lamb to a cutting board. Pull meat off bone and shred into pieces. Return meat to baking sheet and toss in herby juices.
Transfer lamb to a platter. Pour juices over lamb and potatoes. Top lamb with reserved herb mixture. Drizzle lamb and potatoes with oil and lemon juice, then sprinkle with sea salt.
