How To Make Cajun Alfredo Salmon
Love seafood but finding it hard to think of something easy yet tasty and different? Then you need to try this delicious Cajun Salmon Alfredo! It's packed with flavor, yet simple enough for a weeknight dinner. Let's get cooking!
Season the Salmon
- Fill a Dutch oven pot ⅔ full of water and bring to a boil. Boil the pasta according to the package instructions. Drain with a colander and turn out into a bowl. Toss with a tablespoon of olive oil so pasta does not stick together.
- While pasta is cooking season both sides of the salmon filet.
- Bake or Air Fry the Salmon filet 350 F for 15 to 20 minutes, or until the center flakes.
Prepare The Mushrooms and Alfredo Sauce
- Keep your eye on the pasta and the salmon, but while they are cooking start the Alfredo sauce.
- While the salmon is baking, saute the onions, garlic, and mushrooms in a deep saute pan.
- Open the Alfredo sauce of choice, and empty into the saucepan of mushrooms & onions. Simmer for 5 minutes.
Putting The Cajun Salmon Alfredo Together
- Remove the baked salmon and set it on a plate to cool. Flake it with a fork into large chunks.
- Mix the cooked pasta, mushroom Alfredo sauce, and flaked seasoned salmon into a bowl, or the deep saucepan you used to cook the Alfredo sauce.
- Transfer to a serving bowl and garnish with the sliced green onions and some thyme leaves. Serve and enjoy!

Frequently Asked Questions
The USDA cautions: “do not rinse raw fish, seafood, meat, and poultry. Bacteria in these raw juices can splash and spread to other foods and surfaces. Cooking foods thoroughly will kill harmful bacteria.”
The easiest way to see if your salmon has finished cooking is to gently press down on the top of the fillet with a fork or your finger. If the flesh of the salmon flakes - meaning, it separates easily along the white lines that run across the fillet - it's finished cooking.
