Ingredients Notes

The magic of this dish lies in the quality of its ingredients. Here’s what you’ll need:

Shrimp: Use large, raw shrimp for the best texture. I prefer fresh, but frozen works too—just make sure to thaw and pat them dry before cooking.

Garlic: Freshly minced garlic is key to achieving that deep, aromatic flavor. Don’t skimp on it!

Heavy Cream: This forms the base of the luscious sauce. For a lighter version, you can substitute with half-and-half, but the dish won’t be as rich.

Cheese: A combination of parmesan and mozzarella creates a gooey, golden topping. Parmesan adds a salty, umami depth, while mozzarella ensures that perfect cheese pull.

Breadcrumbs: A light layer of panko breadcrumbs on top gives the gratin its signature crispy crust. If you’re going low-carb, you can skip them or use crushed pork rinds instead.

You’ll also need a shallow baking dish to ensure even cooking and the perfect golden-brown crust.

How To Make This Garlic Shrimp Gratin

Making this dish is a breeze! Let’s break it down step by step.

First, preheat your oven to 400°F (200°C) and lightly grease your baking dish. This helps prevent sticking and ensures easy serving later.

Next, prepare the shrimp. Peel and devein them if necessary, then pat them dry with a paper towel. Dry shrimp sear better and won’t release excess water into the sauce.

In a skillet over medium heat, sauté the garlic in butter until fragrant—about 30 seconds. Be careful not to burn it! Add the shrimp and cook just until they turn pink, about 1-2 minutes per side. Remove from heat.

Now, make the sauce. Stir the heavy cream into the skillet, scraping up any flavorful bits from the bottom. Let it simmer for a minute, then mix in the parmesan cheese and a pinch of salt and pepper. Once the cheese melts and the sauce thickens slightly, remove from heat.

Assemble the gratin by spreading the shrimp evenly in the baking dish. Pour the creamy garlic sauce over the top, then sprinkle with shredded mozzarella and a layer of panko breadcrumbs for that irresistible crunch.

Finally, bake for 10-12 minutes until the cheese is golden and bubbly. For an extra crispy top, broil for the last 2 minutes.

Storage Options

This dish is best enjoyed fresh, but you can store leftovers in an airtight container in the refrigerator for up to 2 days.

To reheat, bake in a 350°F oven for about 10 minutes or until warmed through. Avoid microwaving, as it can make the shrimp rubbery.

Variations and Substitutions

One of the best things about Garlic Shrimp Gratin is how adaptable it is!

• Try different cheeses: Swap mozzarella for gruyère or cheddar for a deeper flavor.
• Make it spicy: Add a pinch of red pepper flakes to the garlic butter for a little heat.
• Use different seafood: This recipe works beautifully with scallops, crab, or even lobster.
• Go keto: Skip the breadcrumbs or use crushed pork rinds for a low-carb topping.
• Add veggies: Spinach, mushrooms, or cherry tomatoes can be added for extra color and nutrition.

However you decide to make it, this Garlic Shrimp Gratin is sure to become a go-to dish in your home!
