Preparing Shrimp Scampi Pasta Bake is simple and enjoyable. Follow these steps for an incredible meal:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C).
2. Cook Pasta: In a large pot of salted boiling water, cook the linguine or spaghetti until al dente as per package instructions. Drain and set aside.
3. Sauté Shrimp: In a large skillet over medium heat, melt 2 tablespoons of unsalted butter. Add the shrimp and cook for about 2-3 minutes until they turn pink. Remove the shrimp from the pan and set them aside.
4. Make Garlic Sauce: In the same skillet, add the remaining butter and minced garlic. Sauté for about a minute until the garlic becomes fragrant.
5. Add Cream and Cheese: Pour in the heavy cream, stirring to combine. Allow it to simmer for about 3-5 minutes. Gradually mix in the Parmesan cheese and half of the mozzarella cheese, stirring until melted and creamy.
6. Combine Ingredients: Return the cooked shrimp to the skillet. Stir in the lemon juice, lemon zest, red pepper flakes (if using), and chopped parsley. Add the drained pasta and mix until everything is well coated.
7. Transfer to Baking Dish: Lightly grease a 9×13-inch baking dish with olive oil. Pour the pasta and shrimp mixture into the dish, spreading it evenly.
8. Top and Bake: Sprinkle the remaining mozzarella cheese on the top. Bake in the preheated oven for 20-25 minutes, or until the cheese is bubbly and golden brown.
9. Cool and Serve: Once baked, remove from the oven and let it cool for a few minutes before serving. Garnish with additional parsley, if desired.
