About This Red Lobster Favorite

Red Lobster’s Shrimp Alfredo has been a staple on their menu for decades, and for good reason. The dish centers on sauteed garlic shrimp served over fettuccine pasta and smothered in a rich, creamy parmesan alfredo sauce. It is the kind of comfort food that feels indulgent and special without being overly complicated. Red Lobster took the classic Italian-American alfredo – which itself was an adaptation of the Roman fettuccine al burro – and gave it a full seafood makeover that became a defining dish for the chain. The combination of buttery cream, sharp parmesan, and sweet-savory shrimp creates a flavor profile that hits every note your palate craves. It became one of their most beloved menu items, ranking alongside the iconic Cheddar Bay Biscuits as a reason people keep coming back. Recreating it at home means you can enjoy that same creamy, garlicky satisfaction on any given Tuesday without the wait or the bill.

Ingredients

For the shrimp and pasta

• 1 lb large shrimp (16-20 count), peeled and deveined
• 12 oz fettuccine pasta
• 3 tablespoons unsalted butter
• 2 tablespoons olive oil
• 4 cloves garlic, minced
• 1 teaspoon Italian seasoning
• 1/2 teaspoon salt
• 1/2 teaspoon black pepper

For the alfredo sauce

• 1/2 cup unsalted butter
• 5 cloves garlic, minced
• 2 cups heavy cream
• 2 cups freshly grated parmesan cheese (Parmigiano-Reggiano – this is THE secret, use the real thing)
• 1/2 teaspoon ground nutmeg
• 1/2 teaspoon white pepper
• 1/4 teaspoon salt
• 1 tablespoon fresh parsley, finely chopped
• 1/4 cup dry white wine (optional, adds depth)
• 2 tablespoons cream cheese (optional, for extra creaminess and body)

For finishing

• Fresh parsley, chopped, for garnish
• Extra freshly grated parmesan, for serving
• Fresh cracked black pepper, to taste
• Cheddar Bay Biscuits on the side (because it is not a Red Lobster meal without them)

Ingredient Substitutions

• Chicken instead of shrimp – use 1 lb boneless chicken breast, sliced thin and seared the same way; cook to 165 degrees internal temperature
• Gluten-free pasta – any GF fettuccine or linguine works beautifully in this sauce; cook according to package directions
• Half-and-half instead of heavy cream – the sauce will be thinner and lighter in calories but still creamy and delicious
• Dairy-free cashew cream alfredo – blend 1 cup soaked cashews with 1 cup water, use dairy-free butter and nutritional yeast in place of parmesan
• Scallops instead of shrimp – bay or sea scallops sear beautifully in butter and work perfectly with this alfredo sauce

Equipment You’ll Need

• Large pot (at least 6-quart) for boiling the pasta
• Large skillet or saute pan (12-inch) for the shrimp and alfredo sauce
• Microplane or fine box grater for freshly grating the parmesan – do not skip this
• Tongs for tossing the pasta and handling the shrimp
• Ladle for adding reserved pasta water to adjust sauce consistency

Step-by-Step Instructions

1. Cook the fettuccine. Bring a large pot of heavily salted water to a rolling boil – it should taste like mild seawater. Add the fettuccine and cook according to package directions until just al dente, usually 10 to 11 minutes. The pasta should have a slight bite left in the center because it will finish cooking in the sauce. Before draining, scoop out at least 1 full cup of the starchy pasta water and set it aside – this is liquid gold for getting your sauce to the perfect glossy consistency. Drain the pasta and set aside.
2. Prep and season the shrimp. Pat the shrimp completely dry with paper towels – this step is non-negotiable if you want a good sear instead of steamed shrimp. Toss the shrimp with Italian seasoning, salt, and black pepper until evenly coated. Dry shrimp plus a hot pan equals that beautiful golden crust that makes this dish look and taste restaurant-quality.
3. Sear the shrimp. Heat butter and olive oil together in your large skillet over medium-high heat until the butter is melted and just beginning to foam. Add the minced garlic and saute for 30 seconds until fragrant. Add the shrimp in a single layer – do not crowd the pan or they will steam instead of sear. Cook for exactly 1.5 minutes per side until pink, opaque, and lightly golden. Remove the shrimp immediately to a plate and set aside. They will finish in the sauce later, so it is okay if they look barely done in the center.
4. Make the alfredo sauce. In the same skillet over medium heat, melt the 1/2 cup butter. Add the minced garlic and cook for 1 minute, stirring constantly, until softened and fragrant. If using white wine, add it now and let it simmer for 1 minute to cook off the alcohol. Pour in the heavy cream and optional cream cheese, stirring to combine. Bring the cream just to a gentle simmer – small bubbles around the edges – and let it cook for 5 minutes, stirring occasionally, until it reduces slightly and begins to thicken. Do not let it boil hard or the sauce will break.
5. Add cheese and finish the sauce. Remove the skillet from the heat completely before adding the parmesan. This is the most important step – adding cheese to a sauce that is too hot will cause it to seize up and turn grainy instead of silky smooth. Add the freshly grated parmesan a large handful at a time, whisking after each addition until fully melted and incorporated before adding more. Stir in the nutmeg, white pepper, and salt. Return the shrimp to the sauce along with any juices collected on the plate. Add the drained fettuccine and toss everything together using tongs. Add reserved pasta water a few tablespoons at a time until the sauce coats every strand beautifully and flows just slightly. Garnish with fresh parsley and extra parmesan.

Pro Tips from My Kitchen

• Use real Parmigiano-Reggiano, not the pre-grated green can variety. The difference in your sauce will be night and day – pre-grated parmesan contains anti-caking agents that prevent it from melting smoothly and will leave you with a grainy, clumpy sauce instead of a silky one
• Grate your parmesan fresh right before using it – even the pre-packaged shredded bags from the dairy aisle have anti-caking coatings that interfere with proper melting. A microplane makes this incredibly fast
• Always pull the skillet off the heat before whisking in the parmesan. Cheese added to actively boiling liquid will seize and clump. The residual heat of the pan is more than enough to melt it perfectly
• Nutmeg is the secret depth ingredient in classic alfredo sauce. You only need a small amount but it adds a warm, slightly sweet earthiness that rounds out the richness of the cream and parmesan in a way that is hard to identify but impossible to ignore
• Never boil your cream sauce at a rolling boil – keep it at a gentle simmer with just small bubbles around the edges. Hard boiling breaks the emulsion and you will end up with a greasy, separated sauce
• Shrimp cook in under 3 minutes total and they keep cooking off the heat, so pull them from the pan the moment they turn pink and opaque. Overcooked shrimp turn rubbery and tough, which ruins the whole dish

Recipe Variations

• Chicken Alfredo – replace the shrimp with 1 lb thinly sliced chicken breast, season the same way and sear until golden and cooked through; everything else stays exactly the same
• Mushroom Shrimp Alfredo – saute 8 oz of sliced cremini or baby bella mushrooms in butter before making the sauce; add them back in with the shrimp for an earthy, savory twist
• Lemon Shrimp Alfredo – add the zest of one lemon and a tablespoon of fresh lemon juice to the finished sauce for a bright, fresh contrast to the richness of the cream
• Lighter Half-and-Half Version – substitute half-and-half for the heavy cream for a noticeably lighter sauce; it will be thinner so let it simmer a bit longer to reduce, and consider keeping the cream cheese for body
• Spicy Cajun Shrimp Alfredo – season the shrimp with Cajun seasoning instead of Italian seasoning and add 1/2 teaspoon of red pepper flakes to the sauce; the heat against the rich cream is absolutely addictive

Common Mistakes to Avoid

• Using pre-grated parmesan from a can or bag – the anti-caking agents prevent smooth melting and your sauce will be grainy and lumpy no matter what you do; always grate fresh from a block
• Boiling the cream at high heat – a hard rolling boil breaks the fat from the cream and you end up with a greasy, separated sauce; keep the heat gentle with just a quiet simmer
• Skipping the pasta water – the starchy pasta water is what transforms a heavy cream sauce into something glossy and perfectly coating; without it the sauce often feels thick and gluey rather than silky
• Overcooking the shrimp – shrimp need only 1.5 minutes per side and they continue cooking off the heat; leaving them too long gives you rubber erasers instead of tender, juicy bites
• Not salting your pasta water – under-seasoned pasta tastes flat no matter how good your sauce is; the water should taste noticeably salty before the pasta goes in

What to Serve With This Dish

• Cheddar Bay Biscuits – the ultimate Red Lobster pairing; there are great copycat recipes that come together in under 20 minutes and they are absolutely mandatory for the full experience
• Caesar salad – the crisp, tangy romaine and sharp dressing cut right through the richness of the alfredo and balance every bite
• Garlic bread – you need something to scoop up every last drop of that cream sauce from the bowl; crusty garlic bread is the perfect tool
• Roasted asparagus – the slight bitterness and snap of fresh asparagus is a beautiful contrast to the creamy pasta and adds a pop of green color to the plate
• Simple side salad with lemon vinaigrette – a bright, acidic dressing alongside the rich alfredo keeps the whole meal from feeling too heavy

Storage Instructions

Refrigerator

3 days in an airtight container

Freezer

Not recommended – cream-based sauces separate and turn grainy when frozen and thawed

How to Reheat

Stovetop over low heat is best; add a splash of heavy cream or whole milk and stir gently until the sauce re-emulsifies and heats through – avoid the microwave if possible as it can make the shrimp rubbery

Make Ahead

Cook the pasta fresh when serving for best texture; the alfredo sauce can be made up to 2 days ahead and stored separately in the fridge, then gently reheated over low heat with a splash of cream before tossing with fresh pasta and shrimp

Frequently Asked Questions

What is the secret to a smooth, silky alfredo sauce?

Two things: freshly grated real Parmigiano-Reggiano and pulling the pan off the heat before you add the cheese. Pre-grated parmesan has anti-caking agents that prevent smooth melting. And adding cheese to actively boiling liquid causes it to seize into clumps. Remove from heat, add cheese a handful at a time, whisk after each addition, and you will get a perfectly smooth sauce every time.

Can I use the parmesan that comes in the green shaker can?

I strongly recommend against it. The powdered parmesan in those cans contains cellulose (wood pulp) as an anti-caking agent, which prevents it from melting smoothly into your sauce. You will end up with a grainy, clumpy texture instead of the silky result you are after. A block of real Parmigiano-Reggiano costs a few dollars more but makes all the difference in the world.

Can I use chicken instead of shrimp?

Absolutely, and it is delicious. Use 1 lb of boneless, skinless chicken breast, sliced into thin cutlets or bite-sized pieces. Season it the same way as the shrimp and sear it in the butter and olive oil until golden and cooked through to 165 degrees internal temperature. Remove it from the pan, make your sauce, then add the chicken back in at the end the same way you would the shrimp.

How many calories are in Red Lobster Shrimp Alfredo?

This homemade copycat version comes in at approximately 920 calories per serving with about 48g of protein, 72g of carbs, and 50g of fat. That is actually comparable to the restaurant version. If you want to lighten it up, swapping the heavy cream for half-and-half saves about 150 calories per serving.

Can I make this shrimp alfredo ahead of time?

You can prep components ahead but the best approach is to make the sauce in advance and cook fresh pasta when you are ready to serve. The alfredo sauce keeps well in the fridge for up to 2 days. Reheat it gently on the stovetop over low heat with a splash of cream, then toss with freshly cooked pasta and freshly seared shrimp. Pasta that sits in sauce overnight absorbs the liquid and gets mushy.

Can I freeze shrimp alfredo?

I do not recommend freezing this dish. Cream-based sauces do not freeze well – when thawed they separate and turn watery or grainy rather than returning to their original silky texture. If you have leftovers, store them in the fridge for up to 3 days and reheat gently on the stovetop.

Why did my alfredo sauce turn grainy?

The two most common culprits are pre-grated parmesan with anti-caking agents and adding the cheese while the sauce is still too hot. Always use freshly grated parmesan from a block, and always remove the pan completely from the heat before whisking in the cheese. If your sauce does break, try whisking in a tablespoon or two of pasta water over very low heat to help bring it back together.

Can I make this recipe with gluten-free pasta?

Yes, this recipe works perfectly with gluten-free fettuccine or linguine. Cook it according to the package directions since GF pasta often has different timing than regular pasta. Still reserve your pasta water – it is just as useful for adjusting sauce consistency with GF pasta. The sauce itself is naturally gluten-free.

Why do you add nutmeg to alfredo sauce?

Nutmeg is the classic secret in traditional Italian cream sauces and it might seem surprising but it makes a real difference. It adds a very subtle warm, slightly sweet depth that you cannot quite put your finger on but that makes the sauce taste more complex and restaurant-quality. Start with just 1/2 teaspoon – you do not want it to be obvious, just a background warmth.

Is there a lighter version of this recipe?

Yes – swap the heavy cream for half-and-half and reduce the butter in the sauce by half. You can also skip the optional cream cheese. The sauce will be noticeably lighter in texture and calories but still creamy and satisfying. Another option is to use a mix of half cream and half chicken broth, which gives you some of the body without all the fat. The parmesan is non-negotiable for flavor though.

How much pasta and sauce is one serving?

This recipe makes 4 generous servings. Each serving works out to about 3 oz of dry pasta (before cooking), roughly 4 to 5 large shrimp, and about 1/2 cup of alfredo sauce. If you are serving this as a side dish alongside other proteins or starters, it will easily stretch to 6 portions.

Can I add vegetables to this shrimp alfredo?

Absolutely – it is a great way to add color, nutrition, and variety. Broccoli florets (steamed and added at the end), fresh baby spinach (wilted right into the warm sauce), sliced cherry tomatoes, roasted red peppers, or sauteed mushrooms all work beautifully. Add them in with the shrimp when you are tossing everything together at the end so they heat through without getting overcooked.
