Garlic Butter Shrimp Alfredo Bake Made Stepwise

Step 1: Cook the Fettuccine

Bring a large pot of salted water to a boil. Add the 8 oz fettuccine pasta and cook according to package instructions until al dente. Drain and set aside, reserving about 1/2 cup of pasta water to adjust sauce consistency later if needed.

Step 2: Sauté the Shrimp

In a large skillet, melt 4 tablespoons of unsalted butter over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant but not browned. Add the peeled and deveined shrimp, sprinkle with salt, pepper, and garlic powder, and cook for 2-3 minutes per side until shrimp turn pink and opaque. Remove shrimp from skillet and set aside.

Step 3: Prepare the Alfredo Sauce

In the same skillet, pour in 1 cup of heavy cream. Bring to a gentle simmer over medium-low heat. Stir in 1 cup grated Parmesan cheese until melted and smooth. Season with salt and pepper to taste. If sauce is too thick, stir in reserved pasta water a tablespoon at a time until desired consistency is reached.

Step 4: Combine Pasta, Shrimp, and Sauce

In a large mixing bowl, toss the cooked fettuccine with the Alfredo sauce and sautéed shrimp. Make sure the pasta is evenly coated with the creamy sauce.

Step 5: Assemble the Bake

Transfer the pasta mixture into a greased 9×13-inch baking dish. Sprinkle 1 cup shredded mozzarella cheese evenly over the top.

Step 6: Bake to Perfection

Preheat your oven to 375°F (190°C). Bake the pasta for 20-25 minutes or until the cheese is melted, bubbly, and golden brown on top.

Step 7: Garnish and Serve

Remove the bake from the oven and sprinkle with 2 tablespoons of freshly chopped parsley. Serve hot and enjoy the creamy, garlicky goodness!

Substitutions by Category

• Pasta: Swap fettuccine for linguine, penne, or rigatoni if preferred.
• Shrimp: Use scallops or chunks of cooked chicken breast for an alternative protein.
• Dairy: Substitute heavy cream with full-fat coconut milk for a dairy-free version.
• Cheese: Use Pecorino Romano instead of Parmesan for a sharper flavor.
• Herbs: Fresh basil or chives work well in place of parsley.

Errors to Dodge

• Don’t overcook the shrimp — they should be just pink and opaque to remain tender.
• Avoid letting the garlic brown in the butter, as it can turn bitter.
• Be cautious with salt since Parmesan cheese adds saltiness.
• Don’t skip reserving pasta water; it helps adjust the sauce to the perfect consistency.
• Ensure the baking dish is greased well to prevent sticking.

Prep Ahead & Store

You can cook the pasta and shrimp ahead of time and store them separately in airtight containers in the refrigerator for up to two days. Prepare the sauce fresh before assembling the bake. Once assembled, cover tightly with foil and refrigerate for up to 24 hours before baking.

Leftovers keep well in the fridge for 2-3 days. Reheat in the oven at 350°F (175°C) until warmed through, or microwave in short bursts.
