Creamy polenta
Preheat the oven to 160°C (320°F). Lay the lamb shoulder flat on a clean surface. Season with salt and pepper.
Spread minced garlic, rosemary, and thyme evenly over the lamb. Roll the lamb tightly and secure with cooking twine.
Place the rolled lamb in a roasting pan and roast in the preheated oven for 2 hours or until internal temperature reaches 70°C (160°F).
Remove from oven, let it rest for 15 minutes before slicing.
In a large saucepan, bring water to a boil. Slowly whisk in the polenta, stirring constantly to avoid lumps.
Reduce heat to low and cook for about 30 minutes, stirring frequently until thickened.
Stir in heavy cream, grated parmesan, butter, salt, and black pepper to taste. Mix well until creamy.
