What You’ll Need

• Pasta: 12 ounces fettuccine (or linguine)
• Shrimp: 12 ounces large shrimp, peeled and deveined (tails optional)
• Scallops: 8 ounces sea scallops (pat very dry; cut larger ones in half)
• Butter: 6 tablespoons unsalted
• Olive oil: 1 tablespoon (for searing seafood)
• Garlic: 3–4 cloves, finely minced
• Heavy cream: 1 3/4 cups
• Chicken or seafood broth: 1/2 cup (low sodium)
• Parmesan: 1 1/4 cups freshly grated Parmesan (not pre-shredded)
• Cream cheese (optional but helpful): 2 ounces, softened (adds body and prevents breaking)
• Lemon: Zest of 1/2 lemon, plus 1–2 teaspoons juice
• Parsley: 2 tablespoons chopped, for garnish
• Salt and pepper: To taste
• Red pepper flakes (optional): A pinch, for gentle heat

Instructions

1. Prep the seafood: Pat shrimp and scallops dry with paper towels. Season both lightly with salt and pepper. If scallops are very wet, press with more towels so they sear, not steam.
2. Cook the pasta: Bring a large pot of salted water to a boil. Cook fettuccine until just al dente.Reserve 1 cup pasta water, then drain.
3. Sear the scallops: Heat a large skillet over medium-high. Add olive oil and 1 tablespoon butter. When shimmering, add scallops in a single layer. Sear 1.5–2 minutes per side until golden with an opaque edge. Transfer to a plate.
4. Cook the shrimp: In the same skillet, add 1 tablespoon butter. Add shrimp in a single layer and cook 1–2 minutes per side until pink and just cooked. Transfer to the plate with scallops. Tent loosely with foil.
5. Start the sauce: Reduce heat to medium-low. Add remaining butter to the skillet.Stir in garlic and cook 30–45 seconds until fragrant, not browned.
6. Add liquids: Pour in cream and broth. Stir and bring to a gentle simmer, not a rolling boil. Cook 3–4 minutes to slightly reduce.
7. Thicken and flavor: Whisk in cream cheese until smooth (if using).Gradually add Parmesan, whisking until melted and silky. If it seems too thick, loosen with a splash of pasta water. Season with salt, pepper, lemon zest, and a pinch of red pepper flakes if you like.
8. Combine: Add drained pasta to the sauce and toss to coat. Gently fold in shrimp and scallops, along with any juices from the plate. Warm through 1–2 minutes on low. Add a squeeze of lemon juice to brighten.
9. Serve: Plate immediately. Top with parsley and a little extra Parmesan. Serve with warm bread and a simple salad.

Storage Instructions

• Refrigerate: Cool completely, then store in an airtight container for up to 2 days.
• Reheat gently: Warm in a skillet over low heat with a splash of milk, cream, or broth to loosen the sauce. Stir often.Avoid microwaving on high—use 50% power and short intervals.
• Freezing: Not recommended. Cream sauces can split, and seafood can toughen after thawing.

Why This is Good for You

• Protein-rich: Shrimp and scallops offer lean protein that keeps you full without feeling heavy.
• Omega-3s and minerals: Seafood provides selenium, iodine, B12, and small amounts of omega-3s that support heart and brain health.
• Portion control friendly: The sauce is indulgent, but pairing it with a big side of steamed broccoli or a crisp salad helps balance the meal.
• Made from real ingredients: Fresh garlic, Parmesan, and lemon add flavor without relying on additives.

Common Mistakes to Avoid

• Boiling the cream: High heat can cause the sauce to break or turn grainy. Keep it at a gentle simmer.
• Using pre-shredded Parmesan: It often contains anti-caking agents and won’t melt smoothly.Freshly grate it.
• Overcooking seafood: Shrimp and scallops cook fast. Pull them as soon as they’re opaque and springy.
• Skipping the pasta water: A splash loosens the sauce and helps it cling to the pasta.
• Crowding the pan: Sear scallops and shrimp in a single layer to get that golden edge and keep them tender.

Variations You Can Try

• Mixed seafood: Add lump crab, lobster, or mussels for a deluxe version. Fold delicate crab in at the end.
• Lighter sauce: Swap half the cream for half-and-half and add an extra tablespoon of Parmesan to keep body.
• Garlic mushroom Alfredo: Sauté 8 ounces sliced cremini mushrooms before making the sauce, then proceed.
• Cajun twist: Toss shrimp with 1 teaspoon Cajun seasoning and a pinch of smoked paprika before searing.
• Gluten-free: Use gluten-free fettuccine and ensure your broth and cheese are certified GF.
• Lemon-herb: Add more zest, fresh basil, or tarragon for a brighter profile.

FAQ

Can I use frozen shrimp and scallops?

Yes.

Thaw them overnight in the fridge or under cold running water. Pat very dry before cooking to get a good sear and prevent watery sauce.

What can I use instead of heavy cream?

Half-and-half works, but the sauce will be thinner. Simmer a minute longer and add a bit more Parmesan.

Avoid milk alone—it tends to curdle and won’t give the same richness.

How do I prevent the sauce from getting grainy?

Use freshly grated Parmesan, keep heat moderate, and add cheese gradually while whisking. Don’t let the sauce boil once the cheese goes in.

Which pasta shape is best?

Fettuccine is classic, but linguine, tagliatelle, or even penne work well. Choose a shape with enough surface area to hold the sauce.

Can I make the sauce ahead?

You can make it up to a day in advance, but it thickens as it sits.

Reheat very gently with a splash of cream or broth and whisk until smooth before tossing with fresh pasta and seafood.

What wine pairs well with this dish?

A crisp Pinot Grigio, unoaked Chardonnay, or Sauvignon Blanc cuts through the richness and complements the seafood nicely.

How do I know when scallops are done?

They should be golden on each side and just opaque in the center. Press gently—they’ll feel springy, not squishy or hard. Usually 1.5–2 minutes per side for sea scallops.
