Ingredients

For the gratin filling:

• 1 lb (450 g) large shrimp, peeled and deveined
• 2 tablespoons olive oil or butter
• 3 cloves garlic, minced
• 1 small onion, finely chopped
• 4 cups fresh spinach leaves (or 1 package frozen, thawed and drained)
• 1 cup heavy cream
• ½ cup grated Parmesan cheese
• ½ cup shredded mozzarella cheese
• 2 tablespoons all-purpose flour
• ½ cup milk
• Salt and pepper, to taste
• A pinch of nutmeg (optional)

For the topping:

• ½ cup breadcrumbs (preferably panko)
• 2 tablespoons melted butter
• ¼ cup grated Parmesan cheese
• Chopped parsley, for garnish

Instructions

1. Preheat the oven to 375°F (190°C). Lightly grease a medium baking dish.
2. In a skillet, heat olive oil or butter over medium heat. Add onion and cook until translucent, about 3 minutes. Add garlic and sauté for another 30 seconds until fragrant.
3. Stir in the spinach and cook until wilted (or heated through if using frozen). Remove and set aside.
4. In the same skillet, add the flour and cook for 1 minute. Gradually whisk in milk and cream until smooth and thickened. Stir in Parmesan and mozzarella cheese until melted and creamy. Season with salt, pepper, and nutmeg.
5. Add the shrimp and spinach mixture to the sauce, stirring to coat evenly.
6. Pour the mixture into the prepared dish and smooth the top.
7. In a small bowl, mix breadcrumbs, melted butter, and Parmesan. Sprinkle evenly over the shrimp mixture.
8. Bake for 20–25 minutes, or until the top is golden brown and bubbling.
9. Garnish with chopped parsley and serve hot with crusty bread, rice, or pasta.
