Ingredients

For the Garlic Shrimp:

• 1 pound shrimp (peeled & deveined)
• 2 tablespoons butter
• 4 cloves garlic, minced
• ½ teaspoon salt
• ¼ teaspoon black pepper
• ½ teaspoon red pepper flakes (optional, for spice)
• 1 tablespoon white wine or lemon juice

For the Creamy Sauce:

• 1 tablespoon butter
• 1 tablespoon flour
• ½ cup heavy cream
• ¼ cup milk
• ¼ cup grated parmesan cheese
• ½ teaspoon Dijon mustard
• ¼ teaspoon nutmeg (optional, for depth of flavor)

For the Topping:

• ½ cup shredded mozzarella cheese
• ¼ cup grated parmesan cheese
• ¼ cup panko breadcrumbs
• 1 tablespoon melted butter
• 1 teaspoon chopped parsley (for garnish)

Instructions

Step 1: Preheat & Prep

1. Preheat oven to 400°F (200°C).
2. Lightly grease a baking dish or individual ramekins with butter.

Step 2: Sauté the Shrimp

1. In a skillet, melt 2 tablespoons butter over medium heat.
2. Add minced garlic and sauté for 30 seconds until fragrant.
3. Toss in the shrimp, season with salt, black pepper, and red pepper flakes, and cook for 1-2 minutes per side until just pink (they’ll finish cooking in the oven).
4. Deglaze the pan with white wine or lemon juice, stir, then transfer the shrimp to the prepared baking dish.

Step 3: Make the Creamy Sauce

1. In the same skillet, melt 1 tablespoon butter and whisk in flour to form a roux.
2. Slowly add heavy cream and milk, whisking constantly to prevent lumps.
3. Stir in parmesan, Dijon mustard, and nutmeg. Simmer for 2-3 minutes until thickened.
4. Pour the sauce over the shrimp in the baking dish.

Step 4: Make the Crispy Topping

1. In a bowl, mix panko breadcrumbs with melted butter until coated.
2. Sprinkle shredded mozzarella, parmesan, and buttery panko evenly over the shrimp.

Step 5: Bake Until Golden

1. Bake for 12-15 minutes, or until the top is golden and bubbly.
2. For extra crispiness, broil for 1-2 minutes at the end.

Step 6: Serve & Enjoy!

• Garnish with chopped parsley and serve hot with crusty bread, pasta, or rice.

Notes

• Use fresh shrimp for the best flavor, but frozen (thawed) shrimp works too.
• For a lighter version, use half-and-half instead of heavy cream and reduce the cheese.
• Want extra crunch? Double the panko topping!
• Make it ahead: Assemble everything and refrigerate before baking.

Helpful Tips for the Perfect Garlic Shrimp Gratin

1. Use Fresh or High-Quality Frozen Shrimp

• Fresh shrimp have the best texture and flavor, but if using frozen shrimp, thaw completely and pat dry before cooking to prevent excess water from making the dish soggy.

2. Don’t Overcook the Shrimp

• Shrimp cook very quickly, so only sauté them for 1-2 minutes per side before baking. They will finish cooking in the oven and stay juicy and tender.

3. Use Freshly Grated Cheese for the Best Melt

• Pre-shredded cheese contains anti-caking agents that prevent smooth melting. Grating fresh parmesan and mozzarella makes the gratin extra creamy and delicious.

4. Add a Crispy Golden Top

• Mix panko breadcrumbs with melted butter for an ultra-crispy topping.
• For an extra golden crust, broil for 1-2 minutes at the end—but watch closely to avoid burning!

5. Balance the Richness with a Hint of Acidity

• A splash of white wine or lemon juice helps cut through the creamy sauce, enhancing the flavor.

6. Customize the Texture of the Sauce

• For a thicker sauce: Simmer it a little longer until it coats the back of a spoon.
• For a thinner sauce: Add a small splash of milk or white wine to loosen it up.

7. Make Individual Servings for a Fancy Touch

• Instead of a large baking dish, bake in individual ramekins for an elegant appetizer or dinner party dish.

8. Let It Rest Before Serving

• Allow the gratin to sit for 5 minutes after baking so the sauce thickens slightly, making it easier to serve.

9. Serve with the Right Pairings

• Best with: Toasted baguette slices, pasta, rice, or mashed potatoes to soak up the delicious sauce.
• For a lighter side: Pair with a crisp green salad or steamed veggies.

10. Add a Spicy Kick (Optional)

If you like a little heat, add a pinch of cayenne pepper or extra red pepper flakes to the sauce.

Conservation and Storage

Refrigeration (Short-Term Storage)

• Store leftover Garlic Shrimp Gratin in an airtight container in the refrigerator for up to 3 days.
• Let it cool completely before storing to prevent condensation, which can make the topping soggy.

Freezing (Long-Term Storage)

• Not recommended because creamy sauces can separate, and shrimp can become rubbery when reheated.
• However, you can freeze the sauce separately (without shrimp) for up to 1 month and add fresh shrimp when reheating.

Reheating Instructions

Best Methods for Reheating Without Overcooking the Shrimp:

1. Oven (Best for Crispiness)
   • Preheat oven to 350°F (175°C).
   • Cover with foil and bake for 10-12 minutes, then remove foil and bake for another 2-3 minutes to crisp the topping.
2. Stovetop (Best for Creaminess)
   • Heat in a non-stick pan over low heat, adding a splash of cream or milk to restore moisture. Stir gently.
3. Microwave (Quickest, but Softens Crust)
   • Heat in 30-second intervals, stirring in between.
   • The topping may lose its crispness, so consider broiling it for 1-2 minutes after microwaving.

Make-Ahead Tips

• Assemble in advance: You can prepare the gratin up to 24 hours ahead, store it covered in the fridge, and bake just before serving.
• Reheat leftovers carefully to avoid overcooking the shrimp!
