- Preheat your oven to 375°F (190°C).
- In a large skillet, heat olive oil over medium heat. Add minced garlic and sauté for about 1 minute until fragrant.
- Add spinach and cook until wilted, about 2–3 minutes. Remove from heat and set aside.
- In a mixing bowl, combine heavy cream, Gruyère cheese, Parmesan cheese, lemon zest, salt, and pepper. Mix thoroughly.
- In a baking dish, spread the cooked spinach evenly across the bottom.
- Arrange shrimp on top of the spinach in a single layer.
- Pour the cream and cheese mixture over the shrimp and spinach, ensuring everything is well coated.
- Bake for 20–25 minutes, or until the cheese is bubbly and golden brown.
- Remove from oven and let cool slightly. Garnish with chopped parsley before serving.
Troubleshooting & Consistency Tips
Ensure shrimp are peeled and deveined for even cooking. Avoid overcooking spinach to maintain its bright color. For a richer gratin, add a touch more cheese or a sprinkle of nutmeg to the cream mixture. Serve immediately for optimal creaminess and presentation.
Storage & Make-Ahead
This gratin is best served fresh but can be prepared ahead and refrigerated for up to 24 hours before baking. Reheat gently in the oven at 350°F (175°C) to maintain the creamy texture.
Why This Recipe Works
The combination of creamy cheeses, tender spinach, and succulent shrimp creates a balanced dish with layers of flavor and texture. Baking allows the cheese to meld and form a golden crust, enhancing the dish’s visual appeal and richness.
Expert Tips
- Use fresh, high-quality shrimp for the best flavor.
- Lightly squeeze excess water from spinach to prevent a watery gratin.
- For extra zest, add a squeeze of lemon juice before serving.
- Serve with crusty bread or a simple salad for a complete meal.
