- Preheat oven to 350°. Season lamb shanks with salt and pepper. In a large Dutch oven over medium-high heat, heat oil. Add lamb and cook until golden all over, about 4 minutes per side. Work in batches as necessary. Remove lamb from pot and place on a plate.
- In the pot, melt 2 tablespoons of butter over medium heat. Add onion, mushrooms, carrots and cook until soft, 4 minutes. Add garlic and cook until fragrant, 1 minute more, then add tomato paste and stir until vegetables are coated.
- Pour in broth and tomato sauce, then return lamb shanks to the pot. Add rosemary and bring to a boil. Cover and transfer to oven. Cook until lamb shanks are completely tender, 2 hours.
- Remove lamb from pot and place on a cutting board. Tent with foil to keep warm. Discard rosemary.
- Return pot to stove over medium heat. Add wine and bring to a boil. Reduce heat and let simmer until thickened, 10 minutes. Stir in the remaining 2 tablespoons butter.
- Serve lamb with mashed potatoes and spoon sauce on top.
