How to Make Creamy Garlic Parmesan Shrimp Alfredo Bake
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil. Cook the fettuccine until al dente according to package directions. Drain and set aside.
Step 2: Season and Sear the Shrimp
In a bowl, toss the shrimp with olive oil, smoked paprika, garlic powder, salt, and pepper.
Heat a large skillet over medium-high heat and sear the shrimp for 1 to 2 minutes per side until lightly golden. Remove from the skillet and set aside.
Step 3: Make the Alfredo Sauce
Using the same skillet, melt the butter over medium heat.
Add the garlic and cook for about 30 seconds until fragrant.
Pour in the heavy cream and milk. Stir well and bring to a gentle simmer.
Whisk in the cream cheese until smooth. Add Parmesan cheese, Italian seasoning, salt, and pepper. Continue whisking until the sauce becomes rich and creamy.
Step 4: Add the Spinach
Stir the spinach into the Alfredo sauce and cook until wilted.
Step 5: Assemble the Casserole
Preheat the oven to 375°F.
In a large bowl, combine the cooked pasta, Alfredo sauce, and diced tomatoes.
Transfer the mixture to a 9×13-inch baking dish.
Sprinkle the mozzarella cheese and Parmesan evenly over the top.
Arrange the shrimp across the casserole.
Step 6: Bake
Bake for 15 to 18 minutes, or until the cheese is melted and bubbling.
For a golden cheesy top, broil for 1 to 2 minutes at the end of cooking.
Step 7: Garnish and Serve
Sprinkle with fresh parsley and extra Parmesan cheese before serving.
Enjoy immediately while it’s hot and creamy.
Tips for the Best Shrimp Alfredo Bake
Don’t Overcook the Shrimp
Shrimp cook quickly and will continue cooking in the oven. Sear them briefly to keep them juicy and tender.
Use Fresh Parmesan
Freshly grated Parmesan melts much better than pre-shredded cheese and creates a smoother Alfredo sauce.
Cook Pasta Al Dente
The pasta will continue cooking while baking, so slightly undercooking it helps prevent mushy noodles.
Add Extra Cheese
For an even cheesier casserole, increase the mozzarella to 3 cups.
Storage and Reheating
Refrigerator
Store leftovers in an airtight container for up to 4 days.
Freezer
Freeze for up to 2 months in a freezer-safe container.
Reheating
Warm individual portions in the microwave or reheat covered in a 350°F oven until heated through.
Add a splash of milk or cream if needed to restore the creamy texture.
