Roast lamb with potatoes is Italy's quintessential Easter family feast. This high protein mediterranean dish is a carnivore tradition that fills the house with rosemary and garlic aromas.
Preheat the oven to 375°F, ensuring full heat before roasting.
Peel and cut potatoes into 2-inch chunks; toss with 2 sprigs rosemary, 1/2 cup olive oil, and half the salt.
Pat lamb dry and rub all over with remaining salt, pepper, garlic cloves (smashed), rosemary, and 1/2 cup olive oil.
Layer potatoes in a shallow roasting pan; place lamb on top, drizzle with lemon juice for brightness.
Roast uncovered for 90 minutes, turning potatoes once halfway; monitor lamb internal temp to reach 145°F for optimal moisture.
Rest lamb 15 minutes before slicing; combine roasted potatoes and juices for maximum flavor.
