Start by slicing your salmon into 1 inch cubes and place into a bowl for now. Next, in a small bowl add all of the cajun spices together: salt, pepper, onion powder, garlic powder, thyme, oregano, smoked paprika, red chilli flakes*. Add 1/2 of this cajun seasoning to the salmon and mix well to coat all sides of the salmon pieces.
Next, in a skillet over medium heat add olive oil and heat until shimmering. Add the salmon to the pan and cook on all sides until golden brown. The salmon is done when it starts to flake. Remove the salmon from the pan and place on a plate for now.
In the same pan that cooked the salmon, add the butter. Once the butter is melted, add onions and garlic and sauté for about 2 minutes, then add sun-dried tomatoes. Turn the heat down and set aside just for now.
Meanwhile, In a medium size pot add water and a hefty pinch of salt. Bring the water to a boil and then add fettuccini, save 1/2 cup of pasta water before draining. Cook the pasta until al dente and still has a bite in the middle, drain and set aside for now.
Back to the onions and garlic, turn the heat back to medium and add in white wine. Stir the wine in well, it will scrape off the bits from the bottom o the pan. Next, add the light cream, the rest of the cajun seasoning, dijon mustard and Parmesan cheese. Stir and turn the heat to low-medium low.
Once the pasta is cooked, add the fettuccini to the cream sauce followed by the pasta water. Add the juice of 1/2 lemon and spinach to the pan. Mix the pasta together until cohesive. At this point if you feel like you need more sauce, add light cream a few tablespoons at a time until it reaches desired consistency.
To serve, plate the pasta in you favourite bowls and add more Parmesan on top as well as parsley. Enjoy! 🙂
