Why You Will Love This Recipe
Olive Garden is known for their creamy alfredo sauce. And it is good.
But when I found a way to mimic the alfredo and, dare I say, make it better? It became a dangerous situation.
I do not make homemade alfredo sauce too often because it is so rich. But it is SO good and SO worth it!
This easy shrimp alfredo recipe uses a creamy homemade alfredo sauce with tender shrimp and scallops, all tossed with pasta.
While it may seem more complicated, it is actually an easy dinner and simple recipe whether for date night or a busy weeknight with the whole family.
What is Alfredo?
This Copycat Olive Garden Seafood Alfredo is a fan favorite at the restaurant.
Alfredo is the name of the sauce, and fettuccine is the pasta we typically use here in the United States.
Alfredo sauce has variation to it, but is typically made with butter, cream, and LOTS of Parmesan cheese.
Because there are so few ingredients in this simple dish, I highly recommend using quality ingredients. That means freshly grated cheese.
Ingredients
Here is what you need to make this shrimp alfredo pasta:
- Fettuccine Pasta
- Heavy Whipping Cream
- Butter
- Freshly Grated Parmesan Cheese – fresh Parmesan cheese is best as it melts well. Pre shredded cheese tends to make the sauce grainy.
- Small Shrimp
- Bay Scallops
- Mussels (optional, see Seafood Selection section about this ingredient)
- Ground Nutmeg
- Salt and Pepper
Freshly Grated Parmesan Cheese – I highly recommend using a freshly grated cheese and not pre-shredded nor canned cheese here. The quality of the cheese makes a big difference since it is a big part of the flavor!
Seafood Selection
Fettuccine pasta is coated in an alfredo sauce recipe and tossed with shrimp and scallops.
Now the classic restaurant seafood alfredo recipe uses the extra small shrimp size in their pasta.
You can go with the traditional option and get the extra small shrimp, or you can shake it up and use any shrimp size you like.
Large or extra large shrimp are a favorite around here!
Same with scallops. They use bay scallops which are small, but feel free to switch up the size to larger scallops and adjust cooking time.
The discontinued Olive Garden Seafood Alfredo also had mussels in it several years ago. If you wish to recreate that version, make everything the same however add some mussels as well to the shrimp and scallops. Use your favorite seafood!
Instruction Overview
Cook your fettuccine noodles as per package directions for al dente in a large pot of water on high heat. Drain and set aside.
Make the creamy alfredo sauce: melt butter, heavy cream, and nutmeg together in a large skillet over medium heat.
When the sauce is warm, reduce heat to low heat and add the cheese and stir until melted. At this point, season to taste with salt and pepper as desired.
Add the cooked pasta into the creamy sauce along with the raw shrimp and scallops (they will cook fast since they are so small!) Toss and cook 2-3 minutes until the seafood is done. Garnish with some fresh parsley if desired. Serve.
If you think the sauce is too thick, you can loosen it up with some reserved pasta water at the end.
And it would be great served on its own, or with some homemade garlic bread or a simple side salad.
Modifications and Substitutions
True Parmesan can be expensive, so Romano is a perfect substitute. And Romano is actually what they serve at the restaurant in those cheese graters – not Parmesan!
Use any size shrimp or scallops as desired and just adjust cooking time accordingly. If you are using larger shrimp, sauté shrimp first or cook them longer in the sauce as needed.

Copycat Olive Garden Seafood Alfredo Recipe
Ingredients
- 1 pound fettuccine
- 1/4 pound unsalted butter (1 stick)
- 2 cups heavy cream
- 1/4 teaspoon nutmeg
- 1 1/2 cups freshly grated Parmesan (see note)
- salt
- black pepper
- 1/2 pound extra small shrimp (or shrimp size of choice)(or more if preferred)
- 1/4 pound bay scallops (or size of choice)(or more if preferred)
Instructions
- Start the water for the fettuccine pasta. Cook as per package directions until just shy of al dente (it will be added to the sauce later and will continue to cook). If the pasta is done too early, drain and set aside while reserving 1 cup of the cooking liquid just in case the sauce is too thick.
- As the water is starting for the pasta, combine the butter and cream in a large pot or a wide skillet with tall edges (like the one in my picture). Heat over medium until the butter is melted into the cream.
- Turn heat down to medium low. Add the nutmeg to the cream and butter mixture. Whisk to combine.
- Add the Parmesan cheese. Season with salt and pepper to taste (cheese is salty, so make sure you do not salt until after the Parmesan is added).
- Add the shrimp, scallops, and pasta to the sauce and toss to coat. Let it cook for 2-3 minutes to combine the flavors. If the sauce is too thick, add a little pasta water at a time to loosen the sauce (or cream). If too thin, let it cook a little longer. This should be enough time for the small seafood to cook (see note).
- Remove from heat. Serve immediately.
