Making Shrimp Scampi Pasta Bake is a breeze if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Cook the Pasta: In a large pot of boiling salted water, cook the pasta according to package instructions until al dente. Drain and set aside.
3. Sauté the Shrimp: In a large skillet, heat 2 tablespoons of butter and 2 tablespoons of olive oil over medium heat. Add the shrimp and season with salt, pepper, and red pepper flakes (if using). Cook until the shrimp turn pink, about 2-3 minutes. Remove from skillet and set aside.
4. Prepare the Sauce: In the same skillet, add the remaining butter and olive oil. Add the minced garlic and sauté for about 1 minute until fragrant. Pour in the white wine and cook for about 5 minutes until it reduces slightly.
5. Add Cream and Cheese: Stir in the heavy cream and half of the Parmesan cheese. Mix until smooth, then add the lemon juice and zest. Cook for another 2-3 minutes.
6. Combine Shrimp and Pasta: Add the cooked pasta and shrimp to the skillet, mixing everything thoroughly to ensure the pasta is coated with the sauce.
7. Transfer to Baking Dish: Pour the pasta mixture into a greased 9×13-inch baking dish. Spread it out evenly.
8. Add Cheese Topping: Sprinkle the remaining Parmesan cheese and shredded mozzarella cheese evenly on top.
9. Bake: Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the cheese is bubbly and golden brown.
10. Garnish: Once baked, remove from the oven and let it cool for a few minutes. Garnish with freshly chopped parsley before serving.
