method
- 1
Place peeled, chopped potatoes in a large pot and cover with salted water. Bring to a boil and cook until fork-tender.
- 2
Drain potatoes, then add butter, milk, chives, and salt. Blend with a hand mixer or mash until smooth and creamy. Set aside.
- 3
In a large skillet over medium heat, heat olive oil. Add the diced onion, carrots, and garlic with a pinch of salt; sauté until softened, then remove from the pan and set aside.
- 4
In the same skillet, brown the ground beef, breaking it apart with a spoon until fully cooked. Season with salt and pepper.
- 5
Add the cooked vegetables back to the skillet along with tomato paste, Worcestershire sauce, fresh thyme, and fresh rosemary. Stir to combine.
- 6
Pour in the beef broth and bring to a simmer. Cook until most of the liquid has reduced and thickened.
- 7
Stir in the frozen peas and cook briefly until heated through and thawed.
- 8
Preheat your oven to 400°F (200°C).
- 9
Spread the meat filling evenly into the bottom of a baking dish. Grate a layer of Parmigiano Reggiano over the beef, then spoon the mashed potatoes on top and smooth them out evenly.

Bake at 400°F for about 20 minutes until the edges are bubbling and the potato topping begins to brown. Finish with additional freshly grated Parmigiano Reggiano before serving.
