Hunter-style lamb braised with tomatoes, rosemary, and vinegar from central Italy. This high protein mediterranean family dinner is a rustic carnivore classic with robust, tangy flavors.
Preheat a Dutch oven on medium-high heat, then add olive oil and brown the lamb shoulder pieces thoroughly on all sides for deep flavor.
Reduce heat to medium, add chopped onion, celery, carrot, and garlic, and sauté until vegetables are softened and fragrant—about 7 minutes.
Stir in whole peeled tomatoes, breaking them up with a spoon, and add rosemary sprigs; bring to a simmer over low heat.
Add red wine vinegar, salt, and black pepper; cover and braise gently on the lowest possible heat for 90 minutes, stirring occasionally to prevent sticking.
Remove lid and simmer uncovered for 30 minutes to concentrate flavors and slightly thicken sauce; check lamb for tenderness, adjust salt to taste, and serve.
