Now, let’s talk about the key ingredients that make this gratin so special.

Ingredients Notes

The magic of this garlic shrimp gratin comes from a few high-quality, flavorful ingredients that work together to create the perfect balance of creaminess and richness.

Shrimp is the star of the dish, so choosing the right type is key. Large or jumbo shrimp work best, as they remain juicy and tender after baking. Make sure they’re peeled and deveined for the best texture. If using frozen shrimp, thaw them completely and pat them dry to prevent excess moisture in the sauce.

Garlic brings bold, aromatic flavor to the gratin. Freshly minced garlic is a must—it infuses the sauce with just the right amount of warmth and depth. If you're a garlic lover, feel free to add an extra clove or two for an even stronger kick.

Heavy cream and Parmesan cheese create the luxurious, velvety sauce. The cream provides richness, while Parmesan adds a nutty, salty complexity that enhances the shrimp’s natural sweetness. For a lighter version, you can substitute half-and-half, but keep in mind that the sauce may not be as thick and creamy.

Mozzarella cheese is what gives this gratin its signature golden, bubbly crust. It melts beautifully, creating a stretchy, cheesy topping that perfectly contrasts with the tender shrimp below. For an extra layer of flavor, try mixing in a bit of Gruyère or sharp white cheddar.

A crispy breadcrumb topping adds the final touch of texture. A mix of panko breadcrumbs and butter creates a crunchy contrast to the creamy filling. For even more flavor, toss the breadcrumbs with a bit of minced parsley and grated Parmesan before sprinkling them over the dish.

To bake this gratin to perfection, you’ll need an oven-safe dish or individual ramekins. A broiler-safe option is ideal if you want to get that extra golden finish on top.

How To Make This Garlic Shrimp Gratin

Making this garlic shrimp gratin is easier than you might think, and the result is a dish that tastes like it took hours to prepare.

Start by preheating your oven to 400°F (200°C). Lightly grease your baking dish or ramekins to prevent sticking. If using frozen shrimp, make sure they’re fully thawed, patted dry, and seasoned with a pinch of salt and pepper. This helps enhance their natural flavor.

In a large skillet, melt butter over medium heat and add the minced garlic. Let it cook for about a minute until fragrant, stirring constantly to avoid burning. At this point, your kitchen will be filled with the irresistible aroma of garlic, signaling that it’s time to move to the next step.

Pour in the heavy cream and stir in the Parmesan cheese. Allow the mixture to simmer gently for a few minutes until it thickens slightly. If you want to add an extra depth of flavor, a splash of white wine can be stirred in at this stage. The alcohol will cook off, leaving behind a delicate, slightly tangy note that balances the richness of the sauce.

Once the sauce has thickened, remove it from the heat and gently fold in the shrimp. Be sure to coat each piece evenly in the creamy garlic sauce. Transfer the mixture to your prepared baking dish, spreading it out into an even layer.

Now, it’s time for the best part—the cheese and breadcrumb topping. Sprinkle the mozzarella cheese evenly over the shrimp, followed by the buttery panko breadcrumbs. This combination will create that irresistible golden crust once baked.

Place the dish in the oven and bake for about 12-15 minutes, or until the shrimp are fully cooked and the cheese is bubbly and golden. If you want an even crispier topping, switch the oven to broil for the last minute or two—but keep a close eye on it to prevent burning.

Once out of the oven, let the gratin rest for a few minutes before serving. This allows the sauce to set slightly, ensuring every bite is perfectly creamy and flavorful.

Storage Options

If you have leftovers, you’re in luck—this garlic shrimp gratin stores well and tastes just as delicious the next day.

For refrigeration, transfer the gratin to an airtight container and store it in the fridge for up to 3 days. To keep the topping crispy, store any extra breadcrumbs separately and sprinkle them on just before reheating.

Freezing is possible, but the creamy sauce may change slightly in texture. If you do freeze it, use an airtight container and consume within one month for the best flavor. Let it thaw in the fridge overnight before reheating.

To reheat, warm the gratin in a 350°F (175°C) oven for about 10-15 minutes until heated through. Avoid microwaving, as it can make the shrimp rubbery and the sauce too runny.

Variations and Substitutions

One of the best things about this recipe is how easy it is to customize. Here are a few ways to switch things up to suit your taste.

For a lighter version, swap the heavy cream for half-and-half or even a mix of milk and Greek yogurt. It won’t be as rich, but it will still be deliciously creamy.

Want to add more seafood? Try mixing in lump crab meat or small scallops alongside the shrimp for an even more decadent gratin. Just be sure to adjust the cooking time slightly to ensure everything cooks evenly.

If you love spice, add a pinch of red pepper flakes or a drizzle of hot sauce to the garlic cream sauce. The subtle heat will balance beautifully with the richness of the cheese.

For a low-carb option, skip the breadcrumbs and use a mix of crushed pork rinds and Parmesan instead. This will still give you that crispy topping without the extra carbs.

You can also make this gratin heartier by stirring in cooked pasta or layering it over sautéed spinach or zucchini noodles. It transforms into a full meal while keeping that deliciously creamy texture.

No matter how you customize it, this garlic shrimp gratin is guaranteed to be a crowd-pleaser. Try it out, make it your own, and enjoy every indulgent bite!
