Ingredients

• 12 oz fettuccine (or linguine)
• 1 lb mixed seafood (shrimp, bay scallops, and/or lump crab; peeled and deveined if using shrimp)
• 2 tbsp olive oil
• 4 tbsp unsalted butter
• 4 cloves garlic, finely minced
• 2 cups heavy cream
• 1 cup freshly grated Parmesan (plus extra for serving)
• 1/2 cup grated Romano or more Parmesan (optional for deeper flavor)
• 1/4 tsp nutmeg (freshly grated if possible)
• 1/2 tsp kosher salt, plus more to taste
• 1/2 tsp black pepper (freshly cracked)
• 1 tbsp lemon juice (fresh)
• 2 tbsp chopped parsley (for garnish)
• 1/2 cup pasta cooking water (reserve)
• Optional: pinch of red pepper flakes, 1 tsp Old Bay for the seafood

Instructions

1. Boil the pasta: Bring a large pot of salted water to a boil. Cook fettuccine until just shy of al dente. Reserve 1/2 cup pasta water and drain.
2. Prep the seafood: Pat shrimp and scallops dry.Season lightly with salt, pepper, and Old Bay (optional).
3. Sear the seafood: Heat 2 tbsp olive oil in a large skillet over medium-high. Sear shrimp 1–2 minutes per side until pink and just opaque; remove. Sear scallops 1–2 minutes per side until lightly golden; remove. If using crab, keep it aside to warm in the sauce later.
4. Build the sauce base: Lower heat to medium. Add 4 tbsp butter to the same skillet. When melted, add garlic and cook 30–45 seconds until fragrant (don’t brown it).
5. Cream time: Stir in heavy cream.Simmer gently 3–4 minutes, stirring. Do not boil hard—keep it silky.
6. Cheese it up: Whisk in Parmesan (and Romano if using) in small handfuls until melted and smooth. Add nutmeg, salt, and pepper. Taste and adjust.
7. Finish the sauce: Add lemon juice for brightness. If sauce seems too thick, whisk in a splash of pasta water. If too thin, simmer 1–2 minutes more.
8. Combine: Add drained pasta to the skillet and toss to coat.Fold in shrimp, scallops, and crab (if using). Warm everything for 1–2 minutes on low—don’t overcook the seafood.
9. Garnish and serve: Top with parsley, extra Parmesan, and red pepper flakes if you’re spicy. Serve immediately.

Preservation Guide

• Fridge: Store leftovers in an airtight container up to 2 days.Seafood is delicate; sooner is better.
• Reheat: Low and slow. Warm in a skillet with a splash of cream or milk, stirring gently until creamy again. Avoid microwaving on high—it makes seafood rubbery.
• Freezer: Not recommended. Cream sauces split, and seafood texture suffers. If you must, freeze sauce separately (no seafood), then add freshly cooked seafood when reheating.

What’s Great About This

• Cheese-first flavor: Freshly grated Parmesan melts smoother and tastes sharper. Pre-shredded? It’s coated with anti-caking agents—hard pass.
• One-pan refinement: Sear seafood first, then build the sauce in those savory drippings. That’s free flavor.
• Balanced richness: A squeeze of lemon and a hint of nutmeg keep the sauce from tasting flat or heavy.
• Crowd-proof: Scales easily for 2 or 8. Just use a bigger skillet and don’t overcrowd when searing.

Avoid These Mistakes

• Boiling the cream: Vigorous boil = broken sauce. Keep it to a gentle simmer.
• Adding cheese too fast: Dumping in a mountain of cheese creates clumps. Add gradually, whisking smooth.
• Overcooking seafood: Shrimp and scallops go from perfect to rubber in minutes. Cook just until opaque, then pull them off.
• Skipping the pasta water: That starchy liquid is your ticket to glossy, restaurant-style sauce cling.
• Using watery seafood: If it’s frozen, thaw and pat dry thoroughly.Water dilutes sauce and kills sear.

Recipe Variations

• Lobster Alfredo: Swap in 8–10 oz chopped cooked lobster tails. Gently fold in at the end with a little extra butter. Fancy, yes. Worth it, also yes.
• Cajun Seafood Alfredo: Add 1–2 tsp Cajun seasoning to the sauce and a pinch of cayenne. Bold, smoky, and a little dangerous—in a good way.
• Lighter Alfredo: Use half-and-half instead of heavy cream and add 2 oz cream cheese for body. Not diet food, but your jeans will say thanks.
• Garlic-Spinach Upgrade: Stir in 2 cups baby spinach during the last minute of cooking.Adds color, freshness, and a token vegetable, FYI.
• Lemon-Herb Twist: Add 1 tsp lemon zest and 1 tbsp fresh basil with the parsley for a brighter, summer feel.
• Gluten-Free: Use GF fettuccine and ensure your cheese is GF-friendly. Handle pasta gently to avoid breakage.

FAQ

Can I use milk instead of heavy cream?

Using milk alone will give you a thin sauce that’s prone to curdling. For a lighter option, use half-and-half and add a bit of cream cheese to stabilize and thicken.

What’s the best seafood combo for this?

Shrimp and bay scallops are classic.

Add lump crab for sweetness or lobster for luxury. Keep total seafood to about 1 pound for saucy balance.

Why did my sauce turn grainy?

Either the cream boiled too hard or the cheese was added too quickly (or wasn’t freshly grated). Lower heat and whisk in cheese gradually.

Can I make the sauce ahead?

You can make the Alfredo base 1 day ahead, but reheat gently with a splash of cream and add seafood fresh for best texture.

Fully assembled leftovers are okay but not peak.

What pasta shape works best?

Fettuccine is traditional. Linguine, tagliatelle, or even short shapes like rigatoni work if that’s what you have. The key is enough surface area for sauce cling.

Is nutmeg necessary?

A pinch adds warmth and complexity without tasting “nutmeggy.” It’s subtle but elevates the sauce.

If you don’t have it, no panic—it’s optional.

Can I make it spicy?

Yes—add red pepper flakes to the sauce or finish with a sprinkle on top. Cajun seasoning also plays nicely with seafood.

How do I avoid overcooking scallops?

Use dry, patted-dry scallops, a hot pan, and cook 1–2 minutes per side until lightly golden with a translucent center. They’ll finish warming in the sauce.

My Take

This Copycat Red Lobster Seafood Alfredo Recipe nails the indulgence without the fuss.

The secret is restraint: low heat, fresh cheese, and pulling the seafood the second it’s done. The lemon hit keeps it bright, the nutmeg keeps it classy, and the pasta water brings it all together. Make it once for guests, then pretend it took hours—your secret is safe with me, IMO.
