This creamy Seafood Alfredo Pasta is a wonderful treat! With shrimp and scallops swimming in a rich, cheesy sauce, it’s a meal that feels special without being too hard to make.
You know it’s a hit when even your friends ask for seconds! I like to add a sprinkle of parsley on top for a splash of color. Yum, it’s like a little party on a plate! 🎉
Key Ingredients & Substitutions
Fettuccine Pasta: This classic pasta works beautifully in Alfredo dishes. You can substitute it with spaghetti or linguine if you prefer. Even gluten-free pasta is an option; just ensure to cook it according to package instructions.
Shrimp: Large shrimp are perfect for this dish. If you’re looking for a budget-friendly option, try frozen shrimp; just be sure to thaw and pat them dry before cooking. You can also swap in crab meat or mussels for a different seafood twist.
Sea Scallops: They’re sweet and tender, but if they’re hard to find, you can use shrimp only or even fish like tilapia or cod cut into pieces. Both would work great with the Alfredo sauce.
Heavy Cream: This gives the sauce its richness. If you want a lighter version, you could use half-and-half, though the sauce won’t be quite as creamy. For a dairy-free option, coconut cream can work, but it will alter the flavor.
How Do I Achieve the Perfect Sauce Consistency?
Getting your Alfredo sauce just right is key for a delicious outcome. The process is simple, but here’s how to nail it:
- Start with medium heat when adding the heavy cream to avoid burning. This will help it thicken without scrambling.
- When the cream begins to simmer, give it time (4-5 minutes) to thicken up before adding cheese. Constant stirring is crucial here to keep it smooth.
- Remember to adjust the sauce as you go! If it’s thick, add a splash of pasta water. If too thin, let it simmer a bit longer.
With these tips and ingredient suggestions, you’re on your way to creating a wonderful Seafood Alfredo Pasta that will impress everyone at the table!

Seafood Alfredo Pasta
Ingredients You’ll Need:
For The Pasta and Seafood:
- 12 oz fettuccine pasta
- 1 lb large shrimp, peeled and deveined
- 1/2 lb sea scallops, cleaned
For The Sauce:
- 3 tbsp unsalted butter, divided
- 4 cloves garlic, minced
- 2 cups heavy cream
- 1 cup freshly grated Parmesan cheese
- 1/2 cup grated Romano cheese (optional)
- Salt and freshly ground black pepper, to taste
- 1/4 tsp crushed red pepper flakes (optional)
For The Garnish:
- 2 tbsp fresh parsley, chopped (for garnish)
- 1 tbsp olive oil
How Much Time Will You Need?
This delicious Seafood Alfredo Pasta will take about 30-40 minutes to prepare. You’ll spend about 10-15 minutes cooking the pasta and seafood, and another 15-20 minutes making the creamy Alfredo sauce. It’s a quick dish that’s full of flavor!
Step-by-Step Instructions:
1. Cook the Pasta:
Start by boiling a large pot of salted water. Once it’s bubbling, add in the fettuccine and cook according to the package instructions until it’s al dente. Drain the pasta and set it aside while you prepare the seafood and sauce.
2. Prepare the Seafood:
Next, pat the large shrimp and sea scallops dry with paper towels to help with browning. Lightly season them with salt and pepper on both sides.
3. Sear the Seafood:
In a large skillet, heat 1 tablespoon of butter and 1 tablespoon of olive oil over medium-high heat. Once hot, carefully add the shrimp and scallops. Sear them for about 2-3 minutes per side until they are opaque and cooked through. If your skillet is small, cook the seafood in batches to avoid overcrowding. When done, remove them from the skillet and set them aside.
4. Make the Alfredo Sauce:
Reduce the heat to medium and add the remaining 2 tablespoons of butter into the same skillet. Allow it to melt, then add the minced garlic. Sauté for 1-2 minutes, or until fragrant, but make sure it doesn’t brown.
5. Add the Cream:
Pour the heavy cream into the skillet with the garlic, bringing it to a gentle simmer. Let it cook for about 4-5 minutes until it slightly thickens, stirring occasionally.
6. Stir in the Cheeses:
Now, add the freshly grated Parmesan cheese (and Romano if you’re using it) to the sauce. Stir continuously until the cheese melts completely and the sauce is smooth. Season the sauce with salt, black pepper, and crushed red pepper flakes if you like a little heat.
7. Combine Pasta and Sauce:
Add the cooked fettuccine to the Alfredo sauce, gently tossing to coat the pasta evenly.
Finally, fold in the seared shrimp and scallops, being careful not to break them apart.
8. Serve and Garnish:
Remove the skillet from heat and garnish your Seafood Alfredo Pasta with chopped fresh parsley and more grated Parmesan cheese, if desired. Serve immediately for the best creamy experience!
Bon appétit! Enjoy your luscious Seafood Alfredo Pasta, featuring a creamy sauce, succulent shrimp, and tender scallops.
Can I Use Different Types of Seafood?
Absolutely! While shrimp and scallops are the stars of this dish, you can swap them with other seafood like crab meat, mussels, or even chunks of white fish. Just adjust cooking times accordingly depending on what you choose.
How Can I Make This Recipe Lighter?
To lighten up the Seafood Alfredo, consider using half-and-half instead of heavy cream, and you can reduce the amount of cheese. You can also add more vegetables, like spinach or peas, to bulk up the dish without extra calories.
Can I Make the Sauce Ahead of Time?
Yes, you can prepare the Alfredo sauce ahead of time! Just store it in the fridge for up to 2 days. When ready to use, gently reheat on the stove over low heat and you may need to add a splash of cream or pasta water for a smooth texture.
What Should I Serve with Seafood Alfredo Pasta?
This dish is a meal on its own, but for a complete dining experience, consider serving it with a side salad or garlic bread. Steamed vegetables or a light white wine pair nicely, enhancing the seafood flavors.
