Step-by-Step Garlic Shrimp Gratin Instructions

Prep the Shrimp and Garlic Butter Sauce
- Rinse 1 lb peeled shrimp and pat dry.

- Add 4 minced garlic cloves, cooking until fragrant (about 1 minute).
- Stir in 1 tbsp all-purpose flour to thicken, then whisk in 1 cup heavy cream.
- Simmer gently until creamy and slightly thickened (about 3 minutes).
Combine Shrimp with Sauce
- Add shrimp to the cream sauce; season with salt, pepper, and ½ tsp paprika.
- Cook shrimp gently until just pink and opaque (2–3 minutes); don’t overcook.
Assemble the Gratin
- Transfer shrimp and sauce evenly into a buttered baking dish.
- Mix ½ cup panko breadcrumbs with ½ cup shredded Gruyère or mozzarella cheese.
- Sprinkle mixture evenly over the top.
Bake Until Golden and Bubbling
- Preheat oven to 400°F (200°C).
- Bake gratin for 10–12 minutes until topping is golden brown and cheese melted.

Serve Immediately
- Garnish with finely chopped parsley or chives for freshness.
- Enjoy with crusty bread or your favorite vegetable side.

Tips to Nail the Perfect Texture and Flavor

Cream sauce should coat shrimp lightly but be thick enough to hold toppings.
Cheese choice matters: Gruyère adds nuttiness; mozzarella for stretch and mildness.
Avoid overbaking to preserve shrimp tenderness and prevent drying out.
