  • 2 tbsp olive oil

  • 1 tsp fine salt

  • ½ tsp freshly ground black pepper

• For the Beef & Mushroom Ragù:

  • 1 tbsp olive oil

  • 450 g (1 lb) lean ground beef

  • 1 shallot, finely diced

  • 3 cloves garlic, minced

  • 200 g (7 oz) mushrooms, sliced or quartered if large

  • 200 ml (¾ cup) tomato purée (passata)

  • 1 tbsp Dijon mustard

  • 1 tsp salt

  • ½ tsp freshly ground black pepper

  • Optional pinch of sugar (to balance acidity)

• For Assembly & Topping:

  • 250 g (9 oz) mozzarella cheese, coarsely grated

  • Fresh parsley or chives, chopped, for garnish (optional)

Step‑by‑Step Cooking Directions

1. Preheat & Prep:
   Preheat your oven to 200 °C (390 °F). Line a large baking sheet with parchment paper.

2. Arrange & Roast Potatoes:

   • In a bowl, toss the potato rounds with 2 tbsp olive oil, 1 tsp salt, and ½ tsp pepper until evenly coated.

   • Lay them in a single layer on the prepared sheet. Bake for 30 minutes, flipping once halfway, until edges are golden and centers are tender when pierced with a knife. Remove from oven and set aside.

3. Brown the Beef:

   • While potatoes roast, heat 1 tbsp olive oil in a deep skillet or sauté pan over medium‑high heat.

   • Add the ground beef, breaking it apart with a spatula. Cook for 7 minutes, stirring occasionally, until browned with no pink remaining.

4. Sauté Shallot, Garlic & Mushrooms:

   • Push the beef to one side, add diced shallot and minced garlic to the empty space. Sauté for 2 minutes until the shallot turns translucent and garlic is fragrant.

   • Stir in the mushrooms and cook for 4 minutes until they release their liquid and begin to brown.

5. Build the Ragù Sauce:

   • Stir in 200 ml tomato purée and 1 tbsp Dijon mustard, scraping any browned bits from the pan bottom.

   • Season with 1 tsp salt, ½ tsp pepper, and a pinch of sugar if desired. Cook over medium heat for 5 minutes, stirring occasionally, until the sauce thickens slightly and flavors meld. Remove from heat.

6. Assemble the Casserole:

   • Transfer the roasted potatoes into a 20×30 cm (8×12 in) or similarly sized ovenproof dish, overlapping slightly to cover the bottom evenly.

   • Spoon the beef‑mushroom ragù over the potatoes, smoothing it into an even layer.

7. Add the Cheese Topping & Bake:

   • Sprinkle the grated mozzarella evenly over the ragù layer.

   • Bake in the 200 °C (390 °F) oven for 15 minutes, until the cheese is fully melted, bubbling, and lightly golden.

8. Garnish & Serve:

   • Let rest 5 minutes before slicing.

   • Garnish with chopped parsley or chives for a pop of color. Serve hot.

Origins and Popularity of the Recipe

Potato‑based casseroles have long been staples in Central and Eastern European home cooking, where hearty, affordable ingredients sustain families through cold seasons. The layering of potatoes and meat recalls Hungarian rakott krumpli or German Kartoffelgratin. Incorporating a tomato‑Dijon ragù and a cheesy gratin topping adds an Italian finesse, marrying two traditions into a wholly comforting dish. Today, such fusion casseroles enjoy popularity on dinner tables and food blogs alike for their adaptability and crowd‑pleasing appeal.

Cooking Tips

• Uniform Potato Slices: Use a mandoline or a sharp knife to ensure even cooking.

• Pan Temperature: Don’t overcrowd beef—brown in batches if necessary to develop flavor.

• Rest Before Serving: Letting the casserole sit ensures clean slices and prevents cheese from running.

Variations to Try
