If shrimp Alfredo and salmon Alfredo both sound good and you genuinely can’t decide, this creamy shrimp and salmon Alfredo skips the decision entirely. It combines both proteins in one classic Parmesan cream sauce, giving you the best of both — tender, flaky salmon and juicy shrimp, all coated in the same rich, garlicky Alfredo that makes this dish such a comfort food favorite.
The key to combining two different seafoods in one skillet is respecting how differently they cook. Salmon needs a bit more time and a gentler touch to stay flaky without falling apart, while shrimp cook fast and turn rubbery if left too long. This recipe stages the cooking so the salmon goes in first, has time to nearly finish, and then the shrimp join just long enough to cook through in that same rich sauce.
Because both proteins go in straight from frozen, there’s no need to plan ahead or juggle separate thawing schedules — just a hot skillet, a good Parmesan sauce, and a little attention to timing. Toss the finished combo with fettuccine, and you’ve got a dinner that feels like a genuine seafood-restaurant splurge, made completely at home.

Ingredient Notes
For the salmon, individually frozen fillets (skin removed, if possible) work best, since they’re easy to portion and flake once cooked. Try to choose fillets of similar thickness so they cook evenly, and consider cutting larger fillets into smaller pieces to help them cook at a similar pace to the shrimp.
For the shrimp, frozen, peeled, and deveined shrimp in the medium-to-large range (31/40 or 26/30 count) hold up well in the shorter cooking window this dish uses toward the end. Since shrimp cook much faster than salmon, staggering when each protein is added is really the key detail that makes this combo work.
Freshly grated Parmesan matters quite a bit for a proper Alfredo texture, since pre-shredded bagged cheese is coated in anti-caking agents that can leave the sauce grainy instead of silky smooth. Heavy cream is also essential here — lighter substitutes tend to result in a thinner sauce that doesn’t have the same rich, clinging quality a classic Alfredo should have.

Step-by-Step Instructions
- Cook the pasta. Bring a large pot of salted water to a boil and cook the fettuccine (or pasta of choice) according to package directions until al dente, reserving about a cup of pasta water before draining. Tip: salting the pasta water generously boosts the flavor of the whole finished dish.
- Sear the frozen salmon. Heat butter in a large skillet over medium-high heat, season the frozen salmon with salt and pepper, and cook for about 4–5 minutes per side until browned on the outside but not yet fully cooked through. Tip: don’t worry if the salmon isn’t done yet at this point — it will finish cooking gently in the sauce alongside the shrimp.
- Remove the salmon and sauté the garlic. Set the salmon aside on a plate, lower the heat slightly, and add more butter and the minced garlic to the same skillet, cooking for 30–60 seconds until fragrant. Tip: garlic burns quickly, so keep the heat moderate and stir constantly during this step.
- Build the Alfredo sauce. Pour in the heavy cream, bring to a gentle simmer, and whisk in the Parmesan gradually until smooth and slightly thickened. Tip: adding the cheese a little at a time over moderate heat helps it melt evenly instead of clumping.
- Return the salmon and add the frozen shrimp. Nestle the salmon back into the sauce along with the frozen shrimp, breaking apart any large shrimp clumps, and cover to simmer for 6–8 minutes, until the salmon flakes easily and the shrimp are pink and cooked through. Tip: this is the step to watch closely — check the shrimp a bit early, since they cook faster than the salmon and can turn rubbery if left in too long.
- Combine and serve. Gently flake the salmon into large pieces right in the sauce, then add the drained pasta and toss to coat, using splashes of reserved pasta water to loosen the sauce as needed. Finish with extra Parmesan, black pepper, and chopped parsley before serving.

Storage & Reheating
Leftovers keep in an airtight container in the fridge for up to 2 days — seafood pasta dishes don’t hold up quite as long as some others, so it’s best enjoyed within that window. Reheat gently on the stovetop over low heat with a splash of milk or reserved pasta water, or in the microwave at reduced power in short bursts, to avoid drying out the seafood or turning the shrimp rubbery.
This dish doesn’t freeze well, since both the Alfredo sauce and the seafood lose quality noticeably after being frozen and reheated. It’s best made fresh and enjoyed within a day or two rather than treated as a freezer-friendly meal.
Budget Note
This recipe runs on the higher end at roughly $6–$8 per serving, since combining salmon and shrimp adds up quickly compared to using just one protein. To bring the cost down, use a slightly smaller portion of salmon paired with a larger portion of the more budget-friendly shrimp, and stretch the dish further with a generous amount of pasta per serving.
Variations to Try
Lighter version: Use half-and-half instead of heavy cream and a bit less Parmesan, keeping the heat gentle so the lighter dairy doesn’t separate during the longer simmer with both proteins.
Vegetable-packed version: Stir in baby spinach, sun-dried tomatoes, or asparagus pieces along with the cream and Parmesan for a heartier, more complete one-pan meal.
Cajun twist: Season both the salmon and shrimp with a Cajun seasoning blend before searing for a spicier, smokier take on this same seafood Alfredo combination.
Meal-prep friendly: This dish is best portioned and eaten within a day or two rather than prepped far in advance, since both proteins are more delicate than chicken or beef when it comes to reheating.
Frequently Asked Questions
Can I use fresh salmon and shrimp instead of frozen? Yes — if using fresh or thawed seafood, reduce the initial sear time for the salmon in step 2 to about 2–3 minutes per side, and add the shrimp only in the final 3–4 minutes of cooking rather than the full 6–8.
Why did my salmon fall apart? This usually happens from too much stirring once the salmon is in the sauce. Nestle it in gently and flake it only at the very end, using a light hand rather than stirring vigorously throughout cooking.
Can I make this ahead of time? The Alfredo sauce base can be made a few hours ahead and gently reheated, but the seafood itself is best cooked fresh, since both salmon and shrimp lose quality when reheated after being fully cooked once already.
Can I use just one protein instead of both? Absolutely — this recipe works well with just shrimp or just salmon if you’d rather simplify it; just adjust the cooking time accordingly, since salmon alone will need a bit longer than shrimp alone.
Is this recipe spicy? No, this is a rich, classic, mild dish rather than a spicy one — a pinch of red pepper flakes or a Cajun seasoning swap are easy ways to add heat if you’d like.
