Ingredients Notes

The magic of this Garlic Shrimp Gratin lies in its simple yet flavorful ingredients. Every component plays a crucial role in creating the perfect bite.

Shrimp is the star of the dish, so it's important to use high-quality, fresh or frozen shrimp. I prefer large, deveined shrimp with tails off for easier eating, but if you love that extra seafood flavor, keeping the tails on can add a little depth to the dish.

Garlic is what gives this dish its signature aroma and flavor. Freshly minced garlic works best, as it infuses the creamy sauce with a rich, robust taste. If you’re a garlic lover, don’t be afraid to add an extra clove or two.

Heavy cream creates the luxurious base of the gratin. It thickens beautifully in the oven, making the dish irresistibly rich. If you want a slightly lighter version, you can use half-and-half, though the texture won’t be as thick and creamy.

Cheese is essential for that beautifully golden crust. A combination of Parmesan and Gruyère works best, giving the dish a nutty, slightly sharp flavor with the perfect meltability. If Gruyère isn’t available, Swiss cheese is a great substitute.

Breadcrumbs provide that crispy, golden topping that makes gratin so special. Panko breadcrumbs are my favorite because they stay extra crunchy, but regular breadcrumbs work just as well. Mixing them with a bit of butter before sprinkling ensures an evenly browned crust.

How To Make This Garlic Shrimp Gratin

Making this gratin is easier than you think. Follow these simple steps, and you’ll have a bubbling, cheesy masterpiece ready to serve in no time.

Start by preheating your oven to 400°F. While the oven heats up, prep your shrimp by patting them dry with paper towels. This helps them cook evenly and prevents excess moisture from watering down the sauce.

In a large skillet, melt some butter over medium heat and sauté the minced garlic until it’s fragrant—about 30 seconds. Be careful not to burn it, as burnt garlic can turn bitter. Add the shrimp and cook just until they start turning pink. Remember, they’ll finish cooking in the oven, so don’t overdo it.

Remove the shrimp from the skillet and set them aside. In the same pan, pour in the heavy cream and bring it to a gentle simmer. Stir in a bit of Parmesan and season with salt, pepper, and a pinch of red pepper flakes for a subtle kick. Let the sauce thicken slightly before taking it off the heat.

Transfer the shrimp to a baking dish and pour the creamy garlic sauce over the top. Sprinkle generously with the remaining cheese, followed by the buttered breadcrumbs. This is what will create that gorgeous crispy top when baked.

Bake the gratin for about 10-12 minutes, or until the cheese is bubbly and golden brown. If you want an extra crispy top, turn on the broiler for the last minute or two—just keep an eye on it to prevent burning. Once out of the oven, let it rest for a couple of minutes before serving.

Storage Options

If you have leftovers (which is rare because it’s so delicious), you can store them in an airtight container in the refrigerator for up to two days. Seafood doesn’t keep for too long, so try to enjoy it as soon as possible.

Reheating is simple—pop it in a 350°F oven for about 10 minutes until heated through. Avoid microwaving, as it can make the shrimp rubbery. If the sauce thickens too much, a splash of cream can help restore its creamy consistency.

Unfortunately, this dish isn’t ideal for freezing, as dairy-based sauces tend to separate and become grainy when thawed. For best results, enjoy it fresh!

Variations and Substitutions

One of the best things about this recipe is how adaptable it is. Whether you need to swap ingredients or just want to change things up, here are some ideas to try.

For a different seafood twist, swap the shrimp for scallops or a mix of seafood like lobster and crab. The sauce and topping work beautifully with a variety of shellfish.

If you want a lower-carb version, skip the breadcrumbs and top with extra cheese instead. This still gives you a gorgeous golden crust without the added carbs.

For a smoky touch, try adding a bit of cooked, crumbled bacon to the topping. The saltiness pairs beautifully with the creamy sauce and makes it even more irresistible.

If you're a fan of herbs, sprinkle some fresh parsley or thyme on top before serving. This adds a pop of color and a bit of freshness to balance the richness.

Want to make it even more filling? Serve the gratin over cooked pasta or rice to soak up every last bit of that creamy, garlicky sauce.

This Garlic Shrimp Gratin is a must-try for any seafood lover. Whether you’re making it for a special occasion or just treating yourself to something delicious, it’s guaranteed to impress. So grab some shrimp and get ready to enjoy a dish that’s creamy, cheesy, and completely irresistible!
