Step 1: Bring a large pot of salted water to a boil. Cook pasta according to package instructions until al dente. Reserve ¼ cup of pasta water, then drain.

Step 2: In a small bowl, mix all blackened seasoning ingredients. Pat the salmon dry and coat evenly with the seasoning on both sides.

Step 3: Heat olive oil and butter in a skillet over medium-high heat. Add salmon and cook for 3–4 minutes per side until blackened and just cooked through. Remove salmon and set aside.

Step 4: In the same skillet, reduce heat to medium. Add minced garlic and sauté briefly until fragrant. Pour in heavy cream and bring to a gentle simmer.

Step 5: Stir in Parmesan cheese, black pepper, and nutmeg if using. Cook until the sauce thickens slightly. Add reserved pasta water if needed to loosen the sauce.

Step 6: Add cooked pasta to the sauce and toss until fully coated. Flake the salmon into large pieces and place over the pasta or gently fold it in.
