Juicy shrimp soaked in garlicky cream and topped with a bubbly cheese layer make an amazing dish that turns basic ingredients into something you'd find at a fancy restaurant. This garlic shrimp gratin hits that sweet spot between everyday food and high-end dining, with plump seafood swimming in a smooth sauce that simmers under a crunchy, flavorful crust.
I stumbled on this dish during a freezing night when I wanted something both warm and fancy. Now it's my favorite impressive dinner that packs huge flavor without much work. Even my friends who usually don't like seafood can't resist it after trying just one bite.
Key Ingredients
- Fresh Shrimp: Go for medium or large ones to get good texture and a satisfying bite.
- Garlic: Use fresh cloves for that amazing smell that flows through the whole dish.
- Heavy Cream: This makes the rich base that turns velvety smooth in the oven.
- Cheese Blend: Mozzarella gives you that gooey stretch while Parmesan adds a sharp, nutty kick.
- Panko Breadcrumbs: These Japanese breadcrumbs give you an extra crunchy topping.
Making Your Shrimp Gratin
- Garlic Base:
- Start by slowly cooking minced garlic in butter until it smells amazing but isn't brown yet. This step lets all those garlic flavors soak into the butter and flavor everything else.
- Cooking Shrimp:
- Quickly cook the shrimp in the garlic butter just until they start turning pink. They'll finish cooking later in the oven - you're just adding flavor now.
- Mixing It Up:
- Toss your partly cooked shrimp with heavy cream and cheeses, making sure each piece gets fully coated. This mix creates that amazing sauce that will bubble away while baking.
- Creating The Crust:
- Stir panko breadcrumbs with Parmesan cheese and a bit of melted butter to make a topping that'll turn beautifully golden and crispy in the oven.
- Baking It Right:
- Pop it in the oven until you see bubbling edges and a golden-brown top, showing that everything has come together perfectly.

When I first made this for friends, everyone went quiet as they ate each bite. My biggest win was when my French neighbor, who's super picky about food, asked me how I made it and said it was as good as the gratins he'd eaten in Paris restaurants.
Great Side Dishes
This creamy dish works really well with a basic green salad with lemon dressing to balance the richness. If you want something more filling, add some crusty bread to soak up all that yummy sauce. It tastes great with crisp white wines like Sauvignon Blanc or a light Chardonnay.
Tasty Twists
Switch things up by adding cooked spinach or mushrooms for more flavor and color. Mix in scallops or chunks of white fish with the shrimp for a seafood combo. For a fresh kick, mix some lemon zest into the cream mixture.
Keeping Leftovers
This dish tastes best right away, but you can keep leftovers in the fridge for up to two days in a sealed container. Warm it up slowly in a 325°F oven until it's heated through - don't use the microwave as it'll make the shrimp tough.
After tweaking this dish for years, I've found it's really flexible and hard to mess up. Whether I'm making it for date night or a big dinner with friends, this garlic shrimp gratin always hits that perfect balance of looking impressive while tasting like the comfort food we all crave.

Recipe Questions & Answers

- Yes, you can assemble it all but hold off baking. Chill it for up to a day and bake longer by 5-10 minutes if cold.
- → Which baking dish works best?
- Choose a shallow 9×9-inch dish or gratin tray. For individual servings, use ramekins and trim down baking time.
- → Can veggies be mixed in?
