Creamy Shrimp and Crab Alfredo Bake: The Ultimate Seafood Pasta Casserole

Indulge in This Creamy Shrimp & Crab Alfredo Bake

Some dishes just feel like a warm hug, and for me, this Shrimp and Crab Alfredo Bake is one of them. It’s the kind of meal you make when you want to feel truly spoiled without spending hours in the kitchen. Combining tender shrimp, sweet crab meat, and a rich, creamy Alfredo sauce all baked with a golden layer of cheese is pure comfort food bliss.


Why I love This Recipe

I’m a big believer that great food doesn’t have to be complicated. This recipe is a perfect example of that philosophy. The beauty of this dish lies in its simplicity. We’re talking minimal prep and maximum flavor. Using pre-cooked shrimp and canned or pre-cooked lump crab meat cuts down on the effort significantly, making it an ideal choice for a busy weeknight. The baking process brings all the flavors together beautifully, creating a satisfying, cohesive meal that feels far more decadent than it actually is. It’s also a fantastic way to impress guests or make a special meal for the family without breaking a sweat.


Ingredients

  • 8 ounces fettuccine pasta
  • 1 cup cooked shrimp, peeled and deveined
  • 1 cup lump crab meat
  • 2 cups Alfredo sauce (jarred or homemade)
  • 1 cup shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese
  • 1 teaspoon garlic powder
  • 1 teaspoon Italian seasoning
  • Salt and pepper to taste
  • Fresh parsley for garnish

Swaps and Notes

  • Pasta: While fettuccine is classic, this recipe is incredibly versatile. You could easily swap it for penne, rotini, or even rigatoni. Any pasta that can hold onto a creamy sauce will work beautifully.
  • Seafood: If you’re not a fan of crab, you can double the amount of shrimp or add other seafood like scallops or lobster for a truly luxurious twist. Just be sure to cook them beforehand.
  • Alfredo Sauce: Using a high-quality jarred Alfredo sauce is a great shortcut. However, if you have a little extra time, a homemade sauce will take this dish to the next level. A simple sauce of butter, heavy cream, and Parmesan cheese is easy to whip up.
  • Cheese: The mozzarella and Parmesan combination provides the perfect gooey, cheesy topping. Feel free to experiment with other cheeses like provolone or gruyère for a different flavor profile.
  • Seasoning: If you want a little more heat, a pinch of red pepper flakes would be a fantastic addition to the sauce mixture. You can also use fresh garlic instead of garlic powder for a more robust flavor. Just sauté a couple of minced cloves in a little olive oil before mixing everything together.

List of Steps for the Recipe

  1. Preheat the oven: Set your oven to 350°F (175°C). Grease a medium-sized baking dish (a 9×13-inch dish works well).
  2. Cook the pasta: Boil the fettuccine according to the package directions. Make sure to salt the water generously. Once it’s al dente, drain it and set it aside.
  3. Combine the ingredients: In a large mixing bowl, gently combine the cooked shrimp, lump crab meat, Alfredo sauce, garlic powder, Italian seasoning, salt, and pepper.
  4. Add the pasta: Fold the cooked pasta into the seafood and sauce mixture until every strand is coated in the creamy sauce.
  5. Assemble and bake: Transfer the entire mixture to your prepared baking dish, spreading it out in an even layer.
  6. Add the cheese: Sprinkle the shredded mozzarella and grated Parmesan cheese evenly over the top of the pasta.
  7. Bake: Place the dish in the preheated oven and bake for 25-30 minutes, or until the cheese is melted, bubbly, and a beautiful golden brown on top.
  8. Garnish and serve: Remove the bake from the oven. Let it rest for a few minutes before sprinkling with fresh parsley for a pop of color and a fresh, herbaceous note. Serve immediately.

Tips for Success

  • Don’t Overcook the Pasta: Since the pasta will continue to cook in the oven, it’s crucial to cook it to just al dente. This prevents it from becoming mushy and ensures a perfect texture.
  • Be Gentle with the Crab: Lump crab meat is delicate. When mixing it into the sauce, use a light hand to avoid breaking up the lumps too much. You want to maintain those distinct, satisfying pieces of crab.
  • Taste and Adjust: Taste your Alfredo sauce mixture before adding the pasta. This is your chance to adjust the salt, pepper, and seasonings to your liking.
  • For a Crispier Topping: If you like a crispier top, you can broil the dish for the last 1-2 minutes of baking. Just watch it carefully so it doesn’t burn!

Serving Suggestions and Pairings

This rich and creamy bake pairs wonderfully with a few simple sides to cut through the richness. A crisp green salad with a light vinaigrette is a perfect choice. You could also serve it with some garlic bread or warm, crusty bread to soak up every last drop of that amazing sauce.

For drinks, a chilled Pinot Grigio or a light-bodied Chardonnay would complement the seafood beautifully without overpowering the flavors. For a non-alcoholic option, sparkling water with a squeeze of lemon is a refreshing choice.


Nutritional Information

(Please note that this is an estimate and will vary based on specific brands and portion sizes)

A single serving of this dish can be a bit decadent. It’s a great source of protein from the shrimp and crab, as well as calcium from the cheese. While it’s higher in fat and calories due to the creamy sauce and cheese, it’s a satisfying meal that’s perfect for an occasional treat. For a slightly lighter version, you can use a reduced-fat Alfredo sauce or a bit less cheese on top.


Storage and Leftover Tips

Leftovers of this Shrimp and Crab Alfredo Bake are fantastic. Store any remaining portions in an airtight container in the refrigerator for up to 2-3 days. When reheating, it’s best to do so in the oven to maintain the texture. Cover the dish with foil and bake at 350°F (175°C) for about 15-20 minutes, or until heated through. You can also use the microwave, but the pasta may become a bit softer.
