How to Make Cajun Salmon Pasta
Cook pasta, grab a skillet to cook the rest of the ingredients, and that’s all! Just follow this step-by-step to see how easy it is to make this meal come together:
- Cook the pasta
Prepare the pasta of your choice according to the package directions. Reserve 1 cup of pasta water. Drain pasta and set aside. - Prepare the salmon
Pat dry salmon fillets with a paper towel and season with salt and pepper on both sides. - Cook the veggies
In a large skillet, heat olive oil and butter over medium-high heat. Add the onions and cook for about 4 minutes, until the onions are golden. Add the garlic and stir. Add the tomatoes and cook for about 3 to 4 minutes, until the mixture simmers. Remove from the pan onto a large plate. - Cook the salmon
Add a little more olive oil to the pan, and cook the salmon for 4 to 6 minutes per side until golden/seared on each side and the meat separates easily with a fork. Remove from the pan onto the plate. - Make the sauce
Add the cream or half & half to the pan and ½ cup of the reserved pasta water. Bring it to a simmer and scrape the brown bits from the bottom of the pan, using a wooden spatula. Add the Cajun seasoning, and mix to incorporate it with the sauce. - Combine
Break up the salmon into large pieces and add them into the pan along with the tomatoes, onions, and chopped spinach. Toss the cooked pasta in, and mix to coat everything with the sauce. Add the remaining pasta water, a little bit at a time, until the sauce reaches the thickness and consistency you like. - Serve
Serve with chopped parsley and parmesan cheese, if desired, and enjoy!

WOW. This cajun salmon pasta was out.of.this world! My family devoured it. I like that it’s more affordable than other recipes because it has less salmon but you still feel like you eat a lot.
