Ingredients

• 1.5 kg Lamb breast (bone-in or rolled)

• 4 Garlic cloves, minced

• 2 tablespoons Fresh rosemary, finely chopped

• 1 tablespoon Sea salt

• 1 teaspoon Black pepper

• 2 tablespoons Olive oil

• 1 teaspoon Lemon zest

Directions

• Preheat your oven to 160°C (320°F) to ensure a gentle heat that melts the fat layers without toughening the meat.
• Score the fat on the lamb breast in a diamond pattern using a sharp knife, taking care not to cut into the meat itself.
• Rub the olive oil, garlic, rosemary, salt, pepper, and lemon zest thoroughly over every surface, pressing the aromatics into the scores.
• Place the lamb on a wire rack set over a roasting tray to allow the fat to drip away, ensuring a crispy bottom.
• Calculate how long to cook lamb breast in oven by planning for 2 to 2.5 hours of roasting time until the meat is fork-tender.
• Increase the heat to 220°C (425°F) for the final 10-15 minutes to achieve a shatteringly crisp, golden-brown skin.
• Remove from the oven and let the meat rest for at least 15 minutes before slicing to retain the natural juices.

Notes

• Chef’s Secret: If you have time, dry-brine the lamb with salt overnight in the fridge to maximize the crispiness of the skin.
• Storage: Leftovers can be stored in an airtight container for up to 3 days and are excellent when shredded into tacos or salads.
• Substitution: Thyme or dried oregano can be used if fresh rosemary is unavailable for the herb rub.
