3 pounds lamb neck, cut into 2-inch pieces (22 pieces)
Kosher salt and freshly ground black pepper, to taste
4 celery stalks, roughly chopped
2 carrots, roughly chopped
1 yellow onion, roughly chopped
2 garlic cloves
½ cup tomato paste
4 cups chicken stock
1 (750-milliliter) bottle red wine
5 thyme sprigs
2 plum tomatoes, roughly chopped
6 small shallots, peeled
⅓ cup cherry tomatoes
⅓ cup pitted kalamata olives
Directions
Preheat the oven to 350 F. In a 6-quart Dutch oven, heat the oil and butter over medium-high heat. Season the lamb neck pieces liberally with salt and pepper. Sear, turning as needed, until golden brown, 8 to 10 minutes, then transfer to a plate.
Add the celery, carrots and onion to the pot, and cook, stirring as needed, until golden, 8 to 10 minutes. Reduce the heat to medium and add the garlic. Cook until fragrant, 2 minutes, then add the tomato paste and cook until caramelized, 5 minutes more.
Deglaze the pot with the chicken stock and red wine. Bring to a simmer, then add the seared lamb, thyme and plum tomatoes. Return to a simmer, then cover and place in the oven. Cook for 2 ½ hours, then remove the lid and stir in the shallots. Continue cooking for 30 minutes more.
Remove the pot from the oven and transfer the lamb and shallots to a bowl. Strain the cooking liquid, discarding the vegetable solids, then return it to the pot, along with the cooked lamb and shallots, cherry tomatoes and olives. Season with salt and pepper, then serve.
