This creamy cajun salmon pasta recipe is made with flaky salmon, fettuccine noodles and a homemade alfredo sauce, made with fat-free half and half, butter and parmesan cheese. It’s high in protein and ready in about 30 minutes.
The homemade cajun seasoning is flavorful, bold and insanely easy to make. Salmon is simple to cook and filled with fatty acids, making it an ideal fish to add into your recipes. Once cooked you can cut it up and mix into the pasta or serve it whole over the pasta.
You’d never know this was such an easy dinner recipe because it turns out fancy and elegant, making it one of my top recipes to make for a special occasion.

Ingredients and Substitutes:
These are the main ingredients and substitutions. See recipe card below for full ingredients list and instructions for cajun salmon pasta.
- Salmon: you can substitute with a white fish, shrimp or blackened chicken. Keep the seasonings the same.
- Fettuccine Noodles: any preferred noodle works. I prefer this dish with a longer noodle like fettuccine, angel hair or spaghetti but lots of people like this with penne pasta.
- Cajun Seasoning: you can use your favorite grocery store cajun seasoning or make my homemade cajun seasoning recipe.
- Half and Half: this gives the pasta sauce its richness. You can use whole milk, heavy whipping cream or a milk and cornstarch mixture. I don’t recommend trying this with almond or coconut milk.
- All Purpose Flour: or arrowroot flour.
- Butter: used to make the roux but you can substitute with olive oil.
- Parmesan Cheese and Romano Cheese Blend: if you can’t find a bag of both together, use only parmesan cheese.
Variations
- Add baby spinach or bell peppers.
- Add fresh parsley or red pepper flakes for some heat.
- Try this with air fryer blackened salmon.
Dietary Modifications
- For gluten-free, use a gluten-free flour.
How to make this cajun salmon pasta recipe:
Step 1: make the seasoning & prep salmon
Preheat the oven to 450 degrees Fahrenheit. In a small bowl mix together all Cajun spices and set aside. Prep your salmon by rinsing and patting dry with a paper towel. Cut into 4 oz. filets. Line a baking sheet with aluminum foil and drizzle with 1/2 Tbsp. olive oil. Set salmon fillets skin side down. Top filets with 1 Tbsp. olive oil and evenly coat with 2 Tbsp. Cajun seasoning. Using your hand be sure to coat all areas of the salmon with the seasoning.
Step 2: cook the salmon
Place in the oven at 450 degrees Fahrenheit for 12-14 minutes until they are fully cooked and flake easily with a fork. You can also use a meat thermometer and check for doneness. Salmon should read 145 degrees Fahrenheit when fully cooked. Remove the skin (optional) prior to serving once it has been cooked. It should stick to the foil and peel right off.
Step 3: cook pasta
While the salmon cooks, cook 10 oz. fettuccine is a pot according to package instructions. Drain.
Step 4: make the sauce
Heat a large skillet over medium and add in 2 Tbsp. of butter. Melt butter and add garlic. Simmer until you begin to smell the garlic. Add 2 Tbsp. flour and stir until you have a thick paste. Slowly add the half and half a little as a time and whisk until the flour is no longer chunky and the sauce begins to thicken. This takes approximately 5 minutes.
Remove from heat. Add 1 Tbsp. Cajun seasoning to the sauce and stir together well. Sprinkle 1/4 cup of cheese in the sauce and mix. Add the cooked pasta to the creamy sauce and mix together.. Top with chopped parsley and salmon filets and enjoy!
Expert Tip!
If you have leftovers and the pasta becomes too thick and stuck together from the fridge, add a little chicken broth to loosen it up.
Recipe FAQs
You can serve your salmon pasta topped with a salmon filet or break all the salmon up and mix together throughout the pasta. Top with fresh chopped parsley and additional parmesan cheese.
Choose salmon that looks moist with a rich color. Avoid anything dull, grey or with any obvious blemishes. Here is a great article with more information: How to Buy Salmon at the Grocery Store Like a Pro.
This is really personal choice. Farmed salmon may be higher in omega 3’s while wild caught salmon tends to have fewer calories and saturated fat. It’s much easier to find farmed salmon than it is wild. Both wild and farmed salmon are low in mercury and are both considered safe to eat.
