Preheat your oven to 375°F (190°C). Gather your ingredients while the oven warms up.

Melt unsalted butter in a medium saucepan over medium heat. Add minced garlic and sauté for 2-3 minutes until fragrant and lightly golden.

Add the peeled and deveined shrimp to the garlic butter. Cook for about 3-4 minutes until they turn pink and opaque. Be careful not to overcook.

In the same saucepan, mix in chopped parsley, lemon juice, red pepper flakes, and a pinch of salt and pepper.

Cut the hoagie rolls or French bread in half lengthwise and hollow out the center to create 'boats'.

Stuff the shrimp mixture into each hollowed-out bread boat. Top with shredded mozzarella cheese.

Bake in the preheated oven for 10-12 minutes until the bread is golden brown and the cheese is bubbling.

Allow to cool for a few minutes before serving. Slice and optionally garnish with extra parsley.
