Step-by-Step Instructions

Step 1 — Prep Your Ingredients

Gather 1 pound of large shrimp (peeled and deveined), 8 ounces of lump crab meat, 1 pound of fettuccine, 4 cloves of minced garlic, 1 cup of heavy cream, 1 cup of grated Parmesan cheese, and fresh parsley. Pat the seafood dry with paper towels to ensure proper searing and prevent a watery sauce.

Step 2 — Cook the Pasta

Bring a large pot of salted water to a rolling boil. Add the fettuccine and cook according to package directions until al dente. Reserve 1 cup of pasta water before draining, as the starchy liquid helps create a silky Alfredo sauce.

Step 3 — Sauté the Shrimp

Heat 2 tablespoons of olive oil in a large skillet over medium-high heat. Add the shrimp in a single layer and cook for 1–2 minutes per side until pink and opaque. The internal temperature should reach 120°F for perfectly cooked shrimp. Remove and set aside.

Step 4 — Create the Alfredo Base

In the same skillet, melt 4 tablespoons of butter over medium heat. Add the minced garlic and sauté for 30 seconds until fragrant. Pour in the heavy cream and bring to a gentle simmer, stirring constantly to prevent scorching.

Step 5 — Incorporate Cheese and Crab

Reduce heat to low and gradually whisk in the Parmesan cheese until fully melted and smooth. Gently fold in the crab meat, being careful not to break up the lumps. Cook for 2 minutes just to heat through—overcooking will make the crab rubbery.

Step 6 — Combine Pasta and Sauce

Add the drained fettuccine to the skillet along with ¼ cup of reserved pasta water. Use tongs to toss until every strand is coated in the creamy Alfredo sauce. The sauce should cling to the pasta without being too thick—add more pasta water if needed.

Step 7 — Finish with Shrimp and Herbs

Return the cooked shrimp to the skillet and gently fold into the pasta. Taste and season with salt, black pepper, and a pinch of nutmeg if desired. Garnish with chopped fresh parsley for a pop of color and freshness.

Step 8 — Serve Immediately

Divide the Shrimp and Crab Alfredo among warm plates. This creamy seafood pasta is best enjoyed right away while the sauce is luxuriously smooth. Pair with crusty bread to soak up every bit of the delicious sauce.

Healthier Alternatives

• Chicken or Mushrooms — Swap seafood for grilled chicken or sautéed mushrooms for a lighter protein option with savory, earthy notes.
• Zucchini Noodles or Spaghetti Squash — Replace traditional pasta with veggie noodles for a low-carb, gluten-free version that keeps the dish fresh and light.
• Coconut Milk or Cashew Cream — Use dairy-free alternatives for the Alfredo sauce to create a creamy, rich texture with a subtle nutty or tropical flavor.
• Whole Wheat or Chickpea Pasta — Opt for high-fiber, gluten-free pasta options to boost nutrition while maintaining a satisfying, hearty base.
• Low-Sodium Broth & Herbs — Reduce salt by using low-sodium broth and enhancing flavor with fresh basil, parsley, or garlic for a vibrant, aromatic twist.
• Greek Yogurt or Light Cream Cheese — Substitute heavy cream with Greek yogurt or light cream cheese for a tangy, lower-fat sauce that remains luxuriously creamy.
• Steamed Vegetables Mix-In — Add broccoli, spinach, or peas directly into the pasta for extra fiber, vitamins, and color without compromising the creamy seafood essence.

Serving Suggestions

• Pair with a crisp Caesar salad and warm garlic bread for a classic Italian-American dinner.
• Serve alongside steamed asparagus or roasted broccoli to add a fresh, green vegetable element.
• Perfect for a romantic date night at home or a special weekend family meal.
• Garnish with fresh parsley, a sprinkle of Parmesan cheese, and a lemon wedge for brightness.
• Plate in shallow bowls to showcase the creamy sauce and keep the pasta warm longer.

This Shrimp and Crab Alfredo is a versatile dish that works beautifully for both casual gatherings and elegant occasions.

Common Mistakes to Avoid

• Mistake: Overcooking the seafood, resulting in rubbery shrimp and dry crab. Fix: Cook shrimp just until pink and opaque, and gently warm crab at the end to preserve its delicate texture.
• Mistake: Using pre-shredded cheese that contains anti-caking agents. Fix: Always grate fresh Parmesan or Romano cheese yourself for a smoother, creamier sauce that emulsifies properly.
• Mistake: Adding cold cream directly to a hot pan, which can cause the sauce to break. Fix: Let cream come to room temperature before incorporating it gradually into your warm butter and garlic base.
• Mistake: Overcrowding the pan when searing shrimp, leading to steaming instead of browning. Fix: Cook shrimp in a single layer with space between them to achieve that perfect golden sear.
• Mistake: Underseasoning the pasta water, resulting in bland Shrimp and Crab Alfredo. Fix: Salt your pasta water generously—it should taste like seawater—as this is your first opportunity to season the pasta.
• Mistake: Rinsing cooked pasta after draining, which removes the starch that helps sauce adhere. Fix: Transfer pasta directly from pot to sauce, reserving some starchy pasta water to adjust consistency.
• Mistake: Letting the sauce sit too long before serving, causing it to thicken excessively. Fix: Serve your Creamy Seafood Pasta immediately after combining ingredients, as the sauce continues to thicken off heat.
• Mistake: Using low-fat dairy substitutes that don’t provide the rich mouthfeel of traditional Alfredo. Fix: Stick with heavy cream and real butter for that authentic, luxurious texture that defines this dish.

Storing Tips

• Fridge: Store your Shrimp and Crab Alfredo in an airtight container in the refrigerator for up to 3 days.
• Freezer: For longer storage, freeze this creamy seafood pasta in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator before reheating.
• Reheat: Gently reheat on the stovetop over low heat, adding a splash of milk or cream to restore the sauce’s creamy texture. Ensure the internal temperature reaches 165°F (74°C) for food safety.

For the best quality and to prevent the seafood from becoming rubbery, avoid reheating your Shrimp and Crab Alfredo in the microwave. If you must, use a lower power setting and stir frequently.
