🥔 Gattò di Patate
Gattò di Patate
A rich Neapolitan mashed potato bake layered with ham, cheese, and eggs, its name a Neapolitan adaptation of the French 'gâteau,' baked until the top turns deeply golden and crisp.
Gattò reflects the same French Bourbon-era influence found in sartù, its name a phonetic Neapolitan take on gâteau, transforming ordinary mashed potato into a substantial baked dish layered with cured meat and melting cheese.
Ingredients
Equipment: Large pot for boiling, Potato masher, Baking dish
- 1.2 kg (2.6 lb) potatoes, peeled
- 3 eggs
- 80 g (⅓ cup) unsalted butter
- 100 g (1¼ cups) grated Parmigiano-Reggiano
- 150 g (5.3 oz) cooked ham, diced
- 200 g (2 cups) mozzarella or provolone, diced
- 80 ml (⅓ cup) whole milk
- 80 g (¾ cup) breadcrumbs
- Pinch of nutmeg
- Salt and pepper, to taste
Method
- Boil the potatoes until very tender, then drain and mash while still hot.
- Beat in the butter, milk, eggs, Parmigiano, and nutmeg, mixing until smooth. Season well.
- Butter a baking dish and coat with a layer of breadcrumbs.
- Spread half the mashed potato mixture into the dish.
- Layer the diced ham and mozzarella evenly over the potato.
- Cover with the remaining mashed potato, smoothing the top.
- Scatter with more breadcrumbs and a little extra Parmigiano.
- Bake at 200°C (400°F) for 30–35 minutes until deeply golden on top.
- Let rest for a few minutes before slicing and serving.
Chef Tips
- Mash the potatoes while still hot for the smoothest texture, and season generously, as potatoes need confident salting.
- Let the dish rest briefly after baking, which helps it hold together for cleaner slices.
- This dish is excellent served warm as a main course or cut into smaller squares as a side.
Common Mistakes to Avoid
- Under-seasoning the potato mixture, which needs a generous hand with salt to avoid tasting bland.
- Using cold, previously mashed potatoes, which don't incorporate the eggs and butter as smoothly.
- Skipping the breadcrumb topping, which is what gives the finished dish its characteristic crisp top.
