Ingredients Notes

The beauty of Garlic Shrimp Gratin lies in its simple yet flavorful ingredients. Each one plays an essential role in creating this irresistible dish.

Shrimp: Opt for large, raw shrimp that have been peeled and deveined. They cook quickly and stay tender in the creamy sauce. If using frozen shrimp, be sure to thaw and pat them dry before cooking.

Garlic: Fresh garlic is key for an aromatic, rich flavor. Mince it finely to ensure it blends well into the sauce.

Heavy Cream: This forms the base of the sauce, providing a luscious texture. For a lighter version, you can substitute half-and-half, but the sauce may be slightly thinner.

Cheese: A mix of Parmesan and mozzarella ensures the perfect balance of sharpness and melt-in-your-mouth creaminess. Parmesan adds a salty depth, while mozzarella creates a gooey texture.

Breadcrumbs: Panko breadcrumbs work best for a crispy topping. Mixing them with melted butter enhances their crunch and gives the gratin its signature golden crust.

You'll also need an oven-safe baking dish to assemble and bake the gratin to perfection.

How To Make This Garlic Shrimp Gratin

Creating this indulgent Garlic Shrimp Gratin is easier than you might think. Let’s walk through the steps to ensure a perfect result every time.

Start by preheating your oven to 400°F (200°C). While the oven heats, prepare your shrimp by seasoning them with salt and pepper. This helps to bring out their natural sweetness.

In a large skillet, melt butter over medium heat. Add the minced garlic and cook for about 1 minute until fragrant. Be careful not to burn it—garlic becomes bitter when overcooked.

Next, pour in the heavy cream and bring it to a gentle simmer. Stir in the Parmesan cheese, allowing it to melt into the sauce. Once the sauce is smooth, add the shrimp and cook for about 2 minutes, just until they start turning pink. Remember, they will finish cooking in the oven.

Transfer the shrimp and sauce mixture to a greased baking dish. Sprinkle shredded mozzarella evenly over the top, ensuring every bite has a gooey, cheesy layer.

For the perfect crispy topping, combine panko breadcrumbs with melted butter and a pinch of salt. Evenly spread this mixture over the gratin, then bake for about 10-12 minutes, or until the topping is golden brown and bubbling.

Once out of the oven, let the gratin rest for a few minutes before serving. The sauce will thicken slightly, making it even more delicious.

Storage Options

If you have leftovers (though it’s unlikely!), you can store them in an airtight container in the refrigerator for up to 2 days. Keep in mind that seafood is best enjoyed fresh, so try to eat it as soon as possible.

To reheat, place the gratin in an oven-safe dish and warm it at 350°F for about 10 minutes. Avoid microwaving, as it can make the shrimp rubbery.

Freezing is not recommended, as the creamy sauce may separate when thawed.

Variations and Substitutions

One of the best things about Garlic Shrimp Gratin is how customizable it is. Here are a few variations to try:

For a spicy kick, add a pinch of red pepper flakes to the garlic butter sauce.

If you're dairy-free, substitute the heavy cream with coconut cream and use nutritional yeast instead of Parmesan for a similar umami depth.

Want to add extra protein? Toss in some cooked crab meat or scallops along with the shrimp for a seafood medley.

Swap out the breadcrumbs for crushed Ritz crackers for a slightly sweeter, buttery topping.

For a low-carb option, serve the gratin over cauliflower rice instead of pasta or bread.

Experiment with these variations, and you'll find your perfect version of this dish!

This Garlic Shrimp Gratin is the perfect blend of creamy, cheesy, and crispy textures. Whether you're making it for a weeknight dinner or a special occasion, it's sure to be a crowd-pleaser. Give it a try and enjoy every indulgent bite!
