Prepare the Garlic Butter Spread: In a bowl, combine the softened butter with minced garlic. Stir until well mixed.
Toast the Bread: Preheat the oven to 375°F (190°C). Spread the garlic butter evenly over the slices of bread and place them on a baking sheet. Bake for 5-7 minutes until lightly toasted.
Cook the Shrimp: Heat olive oil in a skillet over medium heat. Add the shrimp, lemon juice, salt, and pepper. Cook for about 2-3 minutes per side until the shrimp turn pink and opaque. Remove from heat.
Assemble the Toast: Distribute the cooked shrimp evenly over the toasted bread slices. Sprinkle shredded mozzarella and grated Parmesan cheese on top.
Bake Again: Return the toast to the oven and bake for another 5-7 minutes, or until the cheese is melted and bubbly.
Garnish and Serve: Sprinkle dried parsley over the top and serve immediately while warm. Enjoy!
