Easy Salmon Alfredo Pasta Recipe

I know what you’re thinking. “Salmon Alfredo? Why don’t I just eat a stick of butter?” There’s really no need to take that tone with me, ma’am (or sir). This scrumptious 30-minute easy Cajun Salmon Alfredo sounds way more decadent than it really is thanks to only a small amount of butter and plain old milk instead of heavy cream.

We all know oil in salmon is a good kind of fat (tell that to my thighs…) so this dinner is practically healthy food.

Cajun Salmon Alfredo -

I just tested this recipe again recently (5/2014) since I wrote it a while ago, and I was sure I would need to reduce the amount of milk. It doesn’t seem like such a small amount of flour and butter would be enough to thicken up the milk, but trust me. It works.

If your pasta seems a little dry at the end or when you reheat your leftovers (if you don’t devour it all the first night), you may need to add a couple more tablespoons of milk or pasta cooking water to loosen up the sauce. I recommend serving this with a simple green salad with a tangy vinaigrette to contrast the rich pasta.

Salmon with spicy Cajun flavor dresses up this comforting alfredo pasta dish.

  • Total Time: 30 minutes
  • Yield: 4 1x


  • 12 ounces pasta of your choice
  • 3/4 pound salmon fillet
  • Cajun seasoning, to taste
  • 1 tablespoon butter
  • 1 tablespoon flour
  • 1/4 teaspoon garlic powder
  • 1/8 teaspoon cayenne pepper or more to taste
  • 1/2 teaspoon dried cilantro substitute dried oregano if necessary
  • 1/4 teaspoon kosher salt
  • 2 cups milk 2% or whole
  • 1/3 cup Parmesan cheese


  1. Bring large pot of salted water to a boil.
  2. Lightly season salmon with Cajun seasoning. Cook on the stovetop 3-5 minutes per side, or bake in a 400 degree oven for 15-20 minutes, until fish is still slightly rare in the center.
  3. Cook pasta according to package directions, drain, and set aside.
  4. While pasta and fish cook, melt butter in a large skillet over medium heat. Add flour, and whisk until a smooth paste is formed. Very slowly add the milk, about 1/4 c. at a time, whisking constantly until smooth. (If lumps form, use the back of a fork to crush the lumps and stir into sauce.) Add garlic powder, cayenne, cilantro, and salt and stir. Continue cooking and stirring until sauce gets bubbly and thickens.
  5. Add cheese to sauce and reduce heat to medium-low. Stir until cheese is melted.
  6. When fish is cooked, shred into about 2″ pieces. Add fish to sauce, and very gently stir to combine. Serve over pasta, or add cooked pasta into skillet with sauce and gently toss to coat.

Salmon Alfredo Pasta Recipe Modifications and Substitutions

I know this recipe is pretty straight forward and it is really good as it is but there are a tips and tricks you can use to either simply the recipe or enhance it.

How to simplify my salmon alfredo recipe

  • Substitute canned salmon for cooking fresh. I love fresh salmon but sometimes you are in a rush or do not have fresh salmon or time to thaw frozen salmon. If you have an extra can of salmon in the pantry this is a great recipe to use it in. The cream sauce helps make the salmon nice and moist. You might need to add a touch more milk as the canned salmon will absorb more liquid than the freshly cooked salmon.
  • Use 1/2 teaspoon of cajun seasoning in to the cream sauce instead of the garlic powder, cayenne and dried herbs.

How to enhance this pasta dish to make it even better!

  • Add smoked salmon. You can use a smaller salmon fillet, 6 or 8 ounces and then use 2 or 3 ounces of smoked salmon or lox to add additional flavor. Simply cut up the smoked salmon and add it to the sauce and pasta at the very end before serving. You want the smoked salmon or lox to be warmed by the pasta but not cooked in the sauce.
  • Sautee 1/2 a diced onion and 1 clove of garlic, minced, in the butter until soft before adding the flour.
  • Add a touch of lemon zest or the juice of 1/2 a lemon at the very end before serving. This will really make the dish extra bright and seem a little lighter.
  • Add some fresh basil leaves, chopped parsley, or tarragon on top before serving. The aroma and flavor from the fresh herbs will really make this pasta pop with flavor. Basil and tarragon, which have a mild anise (licorice) flavor, pair great with salmon and cajun seasoning.

Isn’t pasta with alfredo sauce the BEST? Here are some more recipes with alfredo sauce that I know you’ll enjoy:

Hi, Cathi! I’m so sorry for the very delayed response to your question. I’m not sure how I missed your comment earlier! You can definitely use canned pink salmon (no bones or skin) or the pouches. I like using canned fish in my recipes too! Thank you :)

Thank you, Samantha! I have used Tony Chachere’s for years, but I recently switched to Louisiana brand because it’s labeled as gluten free. Either one will work great in this recipe.
