Preheat your oven to 375°F (190°C).

In a large skillet, combine the minced garlic and a tablespoon of butter over medium heat. Sauté until fragrant, about 1-2 minutes.

Add the mixed seafood to the skillet, seasoning with salt and pepper. Cook until the seafood just begins to turn opaque, about 4-5 minutes. Remove from heat and set aside.

In a separate saucepan, combine the heavy cream and lemon juice over medium heat. Bring to a simmer, then gradually add half of the cheese, stirring until melted and smooth.

Mix the seafood into the creamy sauce, ensuring all the pieces are well coated. Transfer the mixture into a greased baking dish.

In a bowl, combine the breadcrumbs with the remaining cheese and a dash of olive oil. Sprinkle this mixture evenly over the seafood mixture in the baking dish.

Bake for 25-30 minutes, or until the top is golden brown and bubbly.

Once done, remove from the oven and let it sit for a few minutes before serving. Garnish with fresh parsley.
