Ingredients in Shrimp & Crab Alfredo Bake
This recipe is packed with delicious ingredients that make every bite incredible. Letโs break it down:
Shrimp
Succulent shrimp adds that sweet seafood flavor that pairs so well with the rich, creamy sauce. Choose large shrimp for a meaty bite that stands up to the Alfredo.
Crab Meat
Lump crab meat brings a delicate sweetness and tenderness that balances the boldness of the shrimp. Itโs the perfect partner to the rich Alfredo sauce.
Fettuccine Pasta
Fettuccine is the perfect pasta for Alfredo. Its wide ribbons catch all the creamy sauce, making each bite extra satisfying.
Heavy Cream
The base of the Alfredo sauce is heavy cream, giving it that luscious, smooth texture. Itโs what makes the sauce so rich and creamy.
Parmesan Cheese
Grated Parmesan adds a salty, nutty flavor to the sauce, and when baked, it creates that golden, slightly crispy top that everyone loves.
Garlic
Garlic brings that aromatic depth of flavor that adds an extra layer of savory goodness to the sauce.
Butter
Butter is essential for the creamy texture of the Alfredo sauce, creating a velvety base that coats the pasta and seafood.
Mozzarella Cheese
Mozzarella brings meltiness and gooeyness to the bake. Itโs the perfect cheese to help everything come together with a luscious, cheesy finish.
Italian Seasoning
A blend of Italian herbs like oregano, basil, and thyme adds an earthy, fragrant flavor that brings all the elements together.
Salt & Pepper
Just a pinch of salt and pepper enhances the natural flavors of the shrimp, crab, and sauce.
Instructions
Ready to make this indulgent, creamy bake? Hereโs how:
Cook the Pasta
Start by cooking the fettuccine pasta according to the package instructions until al dente. Drain the pasta and set it aside.
Cook the Seafood
In a large skillet, melt a little butter over medium heat. Add the shrimp and cook for 2-3 minutes per side, or until theyโre pink and opaque. Add the crab meat and cook for another minute, just to heat through. Remove the seafood from the skillet and set it aside.
Make the Alfredo Sauce
In the same skillet, melt the remaining butter. Add the minced garlic and cook for 1-2 minutes until fragrant. Pour in the heavy cream and bring it to a simmer. Let it cook for 3-4 minutes, stirring occasionally, until the sauce has thickened slightly. Stir in the Parmesan cheese and Italian seasoning, and season with salt and pepper to taste. Continue stirring until the cheese is fully melted and the sauce is smooth.
Combine the Ingredients
Add the cooked pasta, shrimp, and crab to the skillet with the Alfredo sauce. Stir gently to combine, making sure the pasta and seafood are coated with the creamy sauce.
Assemble the Bake
Transfer the pasta and seafood mixture to a greased 9ร13-inch baking dish. Top with shredded mozzarella cheese and a sprinkle of extra Parmesan for that golden, cheesy crust.
Bake to Perfection
Preheat your oven to 350ยฐF (175ยฐC). Place the baking dish in the oven and bake for 20-25 minutes, or until the top is golden brown and bubbly. If you want an extra crispy top, broil for an additional 1-2 minutes at the end.
Serve & Enjoy
Once the Shrimp & Crab Alfredo Bake is out of the oven, let it cool for a few minutes before serving. Garnish with freshly chopped parsley for a pop of color, and enjoy!

How to Serve Shrimp & Crab Alfredo Bake
This dish is a meal in itself, but here are a few ideas to round out the meal:
Garlic Bread: Serve with warm, crusty garlic bread for dipping into that creamy Alfredo sauce. The perfect side to scoop up every last bit of sauce.
Crisp Salad: A fresh, crunchy salad with a tangy vinaigrette is the ideal contrast to the richness of the Alfredo bake. Something like a Caesar or a simple mixed greens salad would do the trick.
Roasted Vegetables: Roasted vegetables like asparagus, broccoli, or roasted tomatoes bring both color and nutrients to your plate, balancing out the creamy richness of the bake.
Wine Pairing: A light, crisp white wine like Sauvignon Blanc or Pinot Grigio pairs beautifully with the seafood and creamy sauce.
Additional Tips
Seafood Substitutions: If youโre not a fan of crab or shrimp, you can easily substitute with chicken, scallops, or any other seafood you prefer. Just be sure to adjust the cooking time accordingly.
Make It Ahead: This dish is perfect for meal prep. You can assemble it ahead of time, cover it tightly, and store it in the fridge for up to 24 hours. When youโre ready to serve, just pop it in the oven and bake as directed.
Make It Spicy: If you love a little heat, sprinkle in some red pepper flakes or add a few dashes of hot sauce to the Alfredo sauce for an extra kick.
Leftovers: Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, simply warm it in the oven at 350ยฐF (175ยฐC) until heated through.
FAQ Section

A1: Absolutely! You can swap the fettuccine for penne, rigatoni, or any pasta you prefer. Just keep in mind that you may need to adjust the baking time slightly depending on the size and shape of the pasta.

A2: Yes! Use gluten-free pasta and ensure the Alfredo sauce is made with a gluten-free flour or thickening agent. This dish can easily be made gluten-free without sacrificing any flavor.
Q3: Can I freeze this dish?
