Prepare the Salmon: Descale the salmon by scraping it with a knife. To minimize mess, place it inside a plastic bag while descaling. Pat dry and season with kosher salt.
Sear the Salmon: Heat a pan over low-medium heat with a bit of oil. Sear the salmon skin-side down for 6-7 minutes, then flip and cook for another 2-3 minutes until golden and fully cooked. Set aside.
Cook the Pasta: Boil fettuccine until al dente according to package instructions. Reserve ½ cup pasta water before draining.
Sauté the Aromatics: In the same pan, heat a little oil over low-medium heat. Sauté cherry tomatoes, garlic, and black pepper for 30 seconds until fragrant. Add spinach and cook for 1 more minute until wilted.
Make the Creamy Sauce: Pour in heavy cream and add the chicken bouillon cube. Simmer over medium heat for 3 minutes, allowing the flavors to blend.
Incorporate the Cheese & Lemon: Stir in Parmesan cheese and lemon zest, letting the cheese melt into the sauce. If needed, add reserved pasta water to loosen the sauce.
Toss in the Pasta: Add the cooked fettuccine and mix until fully coated. Taste and adjust seasoning with salt if necessary.
Finish & Serve: Stir in fresh basil, plate the pasta, and top with seared salmon. Garnish with extra Parmesan and basil if desired.
