Ingredients

Instructions

  1. Step 1: Heat 3 tbsp olive oil in a large heavy-bottomed pot over medium-high heat. Add 2 lbs lamb shoulder chunks in batches, browning on all sides for about 5 minutes per batch; transfer browned lamb to a plate.
  2. Step 2: In the same pot, add 1 large finely chopped onion and sauté for 5 minutes until softened. Add 4 minced garlic cloves and cook for 1 minute until fragrant.
  3. Step 3: Pour in 1/2 cup red wine to deglaze the pot, scraping up browned bits, and reduce for 3 minutes.
  4. Step 4: Return lamb to pot, add 14 oz canned crushed tomatoes, 1 cup pitted and halved Kalamata olives, 1 tbsp dried oregano, 1 tbsp chopped fresh rosemary, 1 tsp salt, 1/2 tsp black pepper, and 1 cup water; stir to combine.
  5. Step 5: Bring to a simmer, cover, reduce heat to low, and cook gently for 2.5 to 3 hours until lamb is tender and sauce thickens, stirring occasionally.
  6. Step 6: Serve warm, spooning sauce over the lamb with crusty bread or rice.
