Ingredients Notes

The magic of this garlic shrimp gratin comes from its simple yet high-impact ingredients. Each component plays a crucial role in achieving the perfect balance of flavors and textures.

Shrimp are the star of the dish, so choose fresh or high-quality frozen shrimp for the best results. Medium to large shrimp work best, as they stay juicy and tender during baking. If using frozen shrimp, be sure to thaw them thoroughly and pat them dry to prevent excess moisture in the sauce.

Garlic is essential for infusing the dish with deep, aromatic flavor. Freshly minced garlic is best, as pre-minced varieties tend to be milder and less fragrant.

Heavy cream and butter form the rich, velvety base of the sauce. The butter enhances the shrimp’s natural sweetness, while the cream ensures a smooth, luscious consistency.

Cheese is what makes the gratin truly special. A combination of Parmesan and Gruyère creates the perfect balance of sharp, nutty, and melty goodness. If you don’t have Gruyère, Swiss cheese or even a sharp white cheddar will work as substitutes.

Breadcrumbs provide that irresistible golden crust. Panko breadcrumbs are the best choice for a light, crispy topping, but regular breadcrumbs will also work well.

For best results, use a shallow baking dish that allows the shrimp to cook evenly while maximizing the crispy topping.

How To Make This Garlic Shrimp Gratin

Creating this mouthwatering gratin is surprisingly simple. Just follow these easy steps for a perfect dish every time.

Start by preheating your oven to 400°F (200°C). While the oven heats up, prepare the shrimp by seasoning them with salt, pepper, and a little olive oil. This helps enhance their natural flavor and ensures they cook up perfectly tender.

In a skillet over medium heat, melt the butter and sauté the minced garlic until fragrant, about 1-2 minutes. Be careful not to let the garlic brown too much, as it can turn bitter. Pour in the heavy cream and stir well, letting it simmer for a couple of minutes to thicken slightly.

Once the sauce has thickened, remove it from the heat and stir in half of the grated cheese. The warmth of the sauce will help melt the cheese, creating a smooth and creamy consistency.

Arrange the shrimp in a single layer in a buttered baking dish, then pour the creamy garlic sauce over the top. Sprinkle the remaining cheese evenly over the dish, followed by the breadcrumbs. For an extra touch of flavor, drizzle a little melted butter over the topping.

Bake the gratin for about 12-15 minutes, or until the top is golden brown and bubbling. If needed, broil it for an extra minute or two to get that perfectly crisp, golden crust.

Storage Options

If you have leftovers, they can be stored in an airtight container in the refrigerator for up to 2 days. The sauce may thicken slightly as it cools, but a gentle reheat will bring it back to life.

To reheat, place the gratin in a 350°F (175°C) oven for about 10 minutes or until heated through. Avoid using the microwave, as it can make the shrimp rubbery.

This dish is best enjoyed fresh, so freezing is not recommended. However, you can prepare the sauce and assemble the dish in advance, storing it in the fridge for up to a day before baking.

Variations and Substitutions

This recipe is wonderfully adaptable, allowing you to tweak ingredients based on your preferences and dietary needs.

For a lighter version, substitute half-and-half for the heavy cream and reduce the butter slightly. The result will still be creamy but with fewer calories.

If you’re a fan of spice, add a pinch of red pepper flakes or a dash of hot sauce to the garlic cream sauce for a little heat.

For a different cheese profile, swap out the Gruyère for mozzarella or even a smoky Gouda. Each variation brings a unique twist to the dish while keeping it deliciously cheesy.

Seafood lovers can mix in other shellfish like scallops or crab meat for an even more indulgent gratin. Just be sure to adjust the cooking time accordingly.

Vegetarians can substitute shrimp with sliced mushrooms or artichoke hearts for a similarly rich and satisfying gratin.

No matter how you choose to customize it, this garlic shrimp gratin is sure to be a hit. Enjoy experimenting with different flavors and finding your perfect version!
