Ingredients
For the Potatoes
-
8 medium potatoes (about 1.2 kg), cut into wedges
-
2 tablespoons olive oil
-
Salt, to taste
-
Black pepper, to taste
-
1 teaspoon red pepper powder
-
1 teaspoon Italian herbs
For the Vegetables
-
1 onion, chopped
-
1 carrot, grated
-
2 garlic cloves, minced
-
2 tablespoons olive oil
-
Salt and black pepper, to taste
For the Egg Mixture
-
3 eggs
-
1 tablespoon mayonnaise
-
Salt and black pepper, to taste
For the Cheese Sauce
-
60 g butter
-
50 g all-purpose flour (about 1/3 cup)
-
400 ml milk (1 3/4 cups)
-
Salt and black pepper, to taste
-
100 g mozzarella cheese, grated
Instructions
Step 1: Bake the Potatoes
Preheat the oven to 180°C (350°F). In a large bowl, toss the potato wedges with olive oil, salt, black pepper, red pepper powder, and Italian herbs. Spread them in a single layer on a baking tray lined with parchment paper. Bake for 30 minutes, or until the edges are lightly golden and slightly crispy. This step forms the flavorful base of the dish.
Step 2: Prepare the Vegetables
While the potatoes are baking, heat 2 tablespoons of olive oil in a skillet over medium heat. Add chopped onion and sauté for 2–3 minutes until translucent. Stir in grated carrot and minced garlic, and cook for another 3–4 minutes until softened and aromatic. Season with salt and black pepper. Remove from heat and set aside.
Step 3: Make the Egg Mixture
In a mixing bowl, crack 3 eggs and beat them with 1 tablespoon of mayonnaise. Season with salt and black pepper. Whisk until smooth and slightly frothy. This mixture helps bind the ingredients while adding richness and lightness.
Step 4: Make the Cheese Sauce
In a saucepan over medium heat, melt the butter. Once fully melted, stir in the flour and whisk for 1–2 minutes to form a roux. Gradually pour in the milk while whisking constantly to prevent lumps. Cook the sauce until it thickens and coats the back of a spoon. Season with salt and black pepper. Add grated mozzarella and stir until melted and smooth. Set aside to cool slightly.
Step 5: Assemble the Dish
Once the potatoes are finished baking, remove the tray from the oven. Pour the egg mixture evenly over the potatoes. Distribute the sautéed vegetables over the egg-covered potatoes. Pour the cheese sauce over everything, ensuring the entire surface is coated. Optionally, sprinkle additional mozzarella cheese on top for an extra golden crust.
Step 6: Bake Again
Return the dish to the oven and bake for an additional 30 minutes, or until the top is golden, bubbly, and slightly crisp around the edges. Allow to rest for 5 minutes before slicing and serving.
