What makes this seafood Alfredo so special? It’s all about balance—the luxurious creaminess of the sauce against the briny sweetness of fresh seafood, the garlicky aroma that fills your kitchen in minutes. Best part? You don’t need chef skills to make it. In less time than it takes to get takeout, you’ll have a decadent meal that feels like a special occasion.

• Creamy dreaminess: That velvety Parmesan sauce coats every bite—no dry noodles here!

Ingredients for Seafood Alfredo Pasta

Here’s what you’ll need to make this dreamy seafood Alfredo – and yes, every single ingredient matters! I’ve learned the hard way that substitutions can change everything, so try to stick to this list if you can.

• 8 oz fettuccine pasta – The wide ribbons hold that creamy sauce perfectly
• 1/2 lb large shrimp, peeled and deveined (tails on or off – your call!)
• 1/2 lb sea scallops – Look for that sweet, fresh ocean smell
• 2 tbsp butter – The real stuff, please. It makes all the difference
• 2 cloves garlic, minced (about 1 tbsp) – Fresh only, none of that jarred stuff
• 1 cup heavy cream – This is not the time for half-and-half
• 1/2 cup freshly grated Parmesan – The powdery stuff in the green can won’t melt right
• Salt and pepper – To taste, but be generous
• 1 tbsp chopped fresh parsley – For that pop of color at the end

Pro tip: Have everything prepped and ready before you start cooking – this dish comes together fast once you get going!

Equipment You’ll Need

Don’t worry—you won’t need any fancy gadgets for this seafood Alfredo pasta! Just grab these basics from your kitchen:

• Large skillet: A 12-inch one works best so everything has room to mingle
• Pasta pot: With a built-in colander if you’ve got one (lifesaver!)
• Tongs: For flipping those scallops like a pro
• Wooden spoon: My trusty sauce-stirring sidekick

That’s it! Now let’s get cooking—your dreamy pasta awaits.

How to Make Seafood Alfredo Pasta

Alright, let’s dive into the good stuff! Follow these steps and you’ll have restaurant-quality seafood Alfredo on your table in no time. I’ve made this dozens of times, and these little tricks make all the difference.

Cooking the Pasta

First things first – get your pasta going! Cook the fettuccine in well-salted boiling water until it’s al dente (usually 1 minute less than package says). Here’s my secret: save about 1/2 cup of that starchy pasta water before draining – it’s liquid gold for adjusting your sauce later!

Sautéing the Seafood

While the pasta cooks, melt butter in your skillet over medium heat. Add the garlic and let it sizzle for just 30 seconds – you want it fragrant but not brown! Toss in your shrimp and scallops (make sure they’re patted dry) and cook until the shrimp turn pink and the scallops turn opaque, about 3-4 minutes total. Don’t overcook them – they’ll finish in the sauce later. Transfer to a plate and cover to keep warm.

Making the Alfredo Sauce

Now for the magic! In the same skillet, pour in the heavy cream and bring to a gentle simmer. Stir in the Parmesan gradually until it’s completely melted and silky smooth. If the sauce seems too thick, stir in a splash of that reserved pasta water. This is when your kitchen will start smelling absolutely incredible!

Finally, add the cooked pasta and seafood back to the skillet, tossing everything together until every strand is coated in that luscious sauce. Give it a taste – add more salt or pepper if needed. And don’t forget that parsley garnish – it adds the perfect fresh finish!

Tips for the Best Seafood Alfredo Pasta

After making this dish more times than I can count, I’ve picked up some foolproof tricks to take your seafood Alfredo from good to “can I have seconds please?”:

• Fresh is best: Seriously, frozen seafood can make your sauce watery. If you must use frozen, thaw completely and pat very dry.
• Don’t skimp on the garnish: That sprinkle of fresh parsley? It’s not just pretty—it cuts through the richness perfectly.
• Room temp seafood: Let shrimp and scallops sit out for 10 minutes before cooking—they’ll sear better instead of steaming.
• Sauce too thin? Simmer a minute longer. Too thick? Pasta water to the rescue!

Trust me—these little touches make all the difference between homemade and “Holy cow, you made this?!”

Variations of Seafood Alfredo Pasta

One of my favorite things about this recipe? How easily you can mix it up based on what you’re craving or what’s fresh at the market. Here are some delicious twists I’ve tried:

• Crab or lobster: Swap in lump crab meat or chopped lobster tails for serious decadence (birthday dinner upgrade!)
• Mussels or clams: Steam them right in the sauce before adding pasta—so briny and delicious
• Veggie boost: Toss in a handful of baby spinach or sautéed mushrooms with the seafood
• Spice it up: A pinch of red pepper flakes adds the perfect kick

The beauty is—once you master the basic Alfredo sauce, your options are endless!

Serving Suggestions

Oh, how I love plating this seafood Alfredo! For the full Italian bistro experience, serve it with warm garlic bread to swipe through that creamy sauce (trust me, you’ll want to lick the plate). A simple arugula salad with lemon vinaigrette on the side cuts through the richness perfectly. Pour some chilled white wine—now that’s amore!

Storing and Reheating

Leftovers? No problem! Store your seafood Alfredo in an airtight container in the fridge for up to 3 days. When reheating, go low and slow—microwave in 30-second bursts or warm gently on the stove with a splash of cream to bring back that silky texture. Pro tip: Add a squeeze of lemon at the end to brighten everything up again. If the seafood seems a bit tough, you probably overheated it—next time, just warm until steaming, not boiling!

Seafood Alfredo Pasta Nutrition

Now, I’m no dietitian, but here’s the scoop on what you’re getting in each comforting bowl of this seafood Alfredo (values are estimates—your actual results may vary depending on exact ingredients). One generous serving packs about 450 calories with a solid 30g protein from all that glorious seafood. You’re looking at 35g carbs (mostly from the pasta) and 25g fat (thank the cream and butter for that luscious texture). It’s definitely a sometimes food in my house—but oh, what a delicious sometimes!

Common Questions About Seafood Alfredo Pasta

I get so many questions about this recipe—here are the ones that pop up most often with my tried-and-true answers:

Can I use frozen seafood?
Yes, but fresh really is best for texture and flavor. If using frozen, thaw overnight in the fridge and pat very dry with paper towels before cooking—excess moisture will make your sauce watery.

How do I make this gluten-free?
Easy! Just swap the fettuccine for your favorite gluten-free pasta (I like brown rice noodles). Double-check that your Parmesan is gluten-free too—some brands use anti-caking agents.

Why did my sauce break or get grainy?
Two likely culprits: cheese added all at once (add it gradually!) or too high heat. Keep the sauce at a gentle simmer—boiling can cause separation.

Can I prep this ahead?
The sauce and seafood can be cooked a few hours in advance, but combine everything just before serving—pasta keeps absorbing liquid as it sits.

What if I don’t have heavy cream?
Whole milk can work in a pinch, but your sauce won’t be as rich. For best results, stick with heavy cream—it’s worth it!
