Ingredients

• 500 ml (2 cups) cream

• 160 grams (1 cup) Parmesan cheese, grated

• 1 bunch spring onions, chopped

• 2 cloves garlic, minced

• 2 zucchinis, sliced into rounds

• 900 grams (2 lbs) potatoes, sliced into rounds

• Salt, to taste

• Black pepper, to taste

• Oregano, to taste

• Sunflower oil, for greasing

Step-by-Step Cooking Directions

1. Preheat the oven
Set your oven to 180°C (350°F). This ensures the oven is hot and ready once your dish is assembled.

2. Prepare the cream mixture
In a large bowl, combine the cream and grated Parmesan cheese. Use a hand mixer or whisk to blend until smooth and slightly thickened. Add the chopped spring onions and minced garlic, mixing them evenly into the creamy base.

3. Slice the vegetables
Wash and dry the zucchinis and potatoes. Slice them into uniform rounds about ⅛-inch thick. Consistent slicing ensures even cooking and a beautiful layered texture.

4. Season the vegetables
Place the zucchini and potato slices in a large bowl. Add salt, black pepper, and oregano to taste. Toss gently to season evenly.

5. Combine with the cream mixture
Pour the cream and cheese mixture over the seasoned vegetables. Mix gently with your hands or a large spoon to ensure all the slices are coated. Let it sit for 10 minutes so the flavors can begin to meld.

6. Assemble the bake
Grease a baking dish with sunflower oil. Transfer the vegetable mixture into the dish, spreading it evenly and layering as needed for a beautiful stacked effect.

7. Bake
Place the dish in the preheated oven and bake for 50 minutes. The top should turn golden brown and the vegetables should be tender when pierced with a knife.

8. Rest and serve
Allow the bake to cool slightly for 5–10 minutes before slicing and serving. This rest time helps the cream set for cleaner portions.

Zucchini and potato are two of the most accessible and versatile vegetables, making this bake incredibly popular across households for its simplicity, flavor, and minimal prep.

The addition of spring onions, garlic, and oregano gives it an aromatic Mediterranean twist while the Parmesan cheese delivers umami depth.
