As a busy mom and environmental scientist, One-Pot recipes are my absolute favorite! Less clean-up means we save on time and water! Total win, win in my book!

Green tip: Speaking of cleanup, if you have a dishwasher-use it! Comparing dishwashing to handwashing, using an efficient dishwasher uses 1/6th the amount of water to get your dishes clean!

And with just ten ingredients and ready in 30 minutes, this one-pot pasta recipe just ticks every single box!

Cajun Salmon Pasta Ingredients

Here’s everything you need:

  • Salmon. You can buy skinless or remove the skin before getting started. 11 ounces should be plenty to serve two, but if you’re cooking for a family of three+, you may want to get a larger cut, and slice it into individual portions.
  • Cajun seasoning. Find it at the store, buy it online, or make your own!
  • Olive oil.
  • Fresh garlic. I love to use 4 cloves of fresh garlic and mince it myself, but if you are sensitive to garlic, just use two.
  • Diced tomatoes. Canned. You can add the contents of the whole can—both the diced tomatoes and the liquid it comes in.
  • Vegetable broth. You can buy it or make your own. You could also use mushroom or chicken broth here.
  • Fettuccine. You can substitute linguine, but other shapes of pasta vary in cooking time.
  • Fresh spinach.
  • Cream. Light cream or half and half is preferred, but you can also use coconut cream!
  • Parmesan Cheese.

Sustainable Seafood

If not done correctly, salmon farming can pose a risk to our environment for several reasons. This includes, but is not limited to, the antibiotics used in salmon farms that can then leach into the surrounding environment and the depletion of other wild fish harvested to feed the salmon.

However, wild-caught salmon poses other risks, including overfishing and bycatch. Plus, there are often issues with availability and access to wild-caught salmon.

So where does that leave us when it comes to sourcing salmon sustainably?

We have two great choices: sustainably farmed salmon, or wild-caught Alaskan salmon.

Green tip: Look for Marine Stewardship Council and Friend of the Sea labels on your fish to ensure they were harvested sustainably.

Cajun Pasta with Salmon Tips and Tricks

Use a Large Sauce Pan or Shallow Pot

One of my favorite things about this dish besides the taste and how quickly it comes together is the fact that it only requires one pot. Use a large saucepan or shallow pot for best results!

It’s best to use a shallow pot or large frying pan rather than a tall and more narrow pot because you want the pasta to be completely submerged in the liquid.

Green tip: If you have an electric range, use a pot or pan that both sits flat on and matches the size of your burner to make sure you are not wasting energy.

Dry and Season Your Salmon

Whether you’re using fresh or frozen, it’s best to completely dry off your fish before coating it in the spice blend. If you are using frozen salmon, make sure to thaw it first.

The easiest way to do this is by placing your fish filets in between two paper towels and pressing them down. Drying the fish will ensure your seasoning blend sticks, and will avoid extra hot oil splatter from additional water on the fish.

Once your salmon is dry, sprinkle about 2 teaspoons of Cajun seasoning on both sides of your fish filet. Set the rest of the Cajun seasoning aside to add to your pasta later.

Fry Your Salmon First

Add your olive oil to the pan and get it hot over medium heat. After heating for about 2 minutes, carefully place your seasoned salmon on the pan and fry for about 5 minutes on both sides. The salmon should reach an inner temperature of 125°F.

Green tip: Fishing for wild-caught salmon poses risks to the environment in the way of bycatch and overfishing. While irresponsible salmon farms have negative effects on the environment, choosing fish from sustainable, organic salmon farms is the most responsible way to enjoy salmon.

If you’re looking for sustainable salmon from an environmentally conscious salmon farm that can be delivered straight to your doorstep, I highly recommend these salmon fillets. It’s important to stress that not all salmon farms are created equal.

Use The Same Pan for Your Pasta

Once your salmon is cooked on both sides, remove it from your pan and set it aside. We will cook the pasta in the same pan to take advantage of any flavor left in there from frying the salmon.

Add your minced garlic first and fry it up for a minute or two until it’s nice and fragrant. Then, you’ll add your diced tomatoes and vegetable broth.

Then, snap your pasta in half and add it to the pan with the rest of your Cajun Seasoning.

Stir Occasionally

Cover to cook the pasta for about ten minutes. Make sure to stir every so often to avoid any burning on the bottom or pasta noodles sticking together.

Add The Spinach and Cream

Next, you’ll remove the cover and add your fresh spinach and cream. Stir and continue to cook uncovered until the spinach wilts and any excess liquid cooks off.

You should be left with creamy pasta.

Add the Parmesan Last

Once you are happy with the consistency of your sauce, remove the pan from heat and add your parmesan cheese. This will add a little extra salt and thicken your sauce slightly.

Serve it Up with the Cajun Salmon

Serve up your pasta with the Cajun-seasoned pasta and voila! Easy, delicious salmon dinner!

How to Properly Store and Reheat Leftover Cajun Salmon Pasta

This Cajun Salmon Pasta will last for 3-4 days in an airtight container in the refrigerator.

The best way to re-heat it is by adding your leftovers to a baking dish and preheating your oven to 375°F. Cover completely with tin foil to trap moisture and heat the pasta and salmon in the oven for 20-25 minutes or until thoroughly heated.

If you feel your leftover sauce has thickened too much, add a little milk or cream (more veggie broth will work in a pinch, too) to add moisture back in before reheating.

If you really want a quicker + easier reheating method, you can safely reheat leftovers in the microwave covered and on high for about 3 minutes. However, the microwave tends to dry out both the salmon and the cream sauce. So, if you have the time, use the oven!

Pro Tips

  • This recipe is best with light cream or half and half, but I also tested it with coconut cream for those who have sensitive stomachs to cream. It still tasted delicious, but there was a subtle hint of coconut. It’s a great option for those who enjoy coconut, but cream or half and half is preferred to allow the Cajun seasoning to shine.

    I’m not sure what qualifies as a “serving”. Thought I would triple the recipe and have linguini for the week. Turns out 6 servings will last me until the month. Be careful and don’t end up with 9lbs of this delicious dish like I did.

    1. oh my goodness, Marcus! I’m so sorry for the confusion with the serving size. I honestly agonized over whether to put 2 or 4 servings because it’s technically two servings of salmon, but 4-6 servings of pasta and ended up going with 2. After reading your feedback, I’m going to switch it to 4! Sorry again for the confusion, but glad it tasted delicious. At least you’ll be eating good (albeit for weeks on end haha!).

  2. 5 stars
    So good! I used a heavy cream alternative and even though it had a hint of vanilla taste, it was still delicious especially with the salmon! Definitely going into the recipe collection!

    1. I’m so glad you enjoyed it, Carley! That’s great to know about the cream alternative. Thank you so much for taking the time to leave your feedback 🙂
