• 2 tbsp olive oil
• 1½ tbsp Cajun seasoning (store-bought or homemade)
• 1 tsp garlic powder
• ½ tsp smoked paprika
• Salt and black pepper, to taste
• 1 tbsp butter (for searing)

For the Alfredo Sauce:

• 2 tbsp butter
• 3 cloves garlic, minced
• 1½ cups heavy cream
• 1 cup freshly grated Parmesan cheese
• ½ cup milk (or more to thin, if needed)
• Salt and pepper, to taste
• ¼ tsp nutmeg (optional, for depth)

For the Pasta:

• 12 oz fettuccine or linguine pasta
• 1 tbsp olive oil
• ½ cup reserved pasta water
• 1 tbsp chopped parsley (for garnish)

Cooking Directions

Step-by-Step Preparation Method

Step 1: Cook the Pasta

1. Bring a large pot of salted water to a boil.
2. Add fettuccine and cook according to package directions until al dente.
3. Reserve ½ cup of pasta water, then drain the pasta. Toss with a drizzle of olive oil to prevent sticking. Set aside.

Step 2: Prepare the Cajun Salmon

1. Pat salmon fillets dry with paper towels.
2. Rub each fillet with olive oil, then season generously with Cajun seasoning, garlic powder, paprika, salt, and pepper.
3. Heat butter in a large skillet over medium-high heat.
4. Place the salmon fillets (skin side down if applicable) and sear for 4–5 minutes per side, depending on thickness, until cooked through and slightly crisp on the edges.
5. Remove salmon from the skillet and set aside on a plate.

Step 3: Make the Alfredo Sauce

1. In the same skillet, reduce the heat to medium and melt 2 tbsp butter.
2. Add minced garlic and sauté until fragrant (about 30 seconds).
3. Pour in heavy cream and bring to a gentle simmer.
4. Stir in Parmesan cheese and whisk until the sauce is smooth and thickened.
5. Season with salt, pepper, and nutmeg (if using). If the sauce is too thick, add milk or reserved pasta water a little at a time until desired consistency is reached.

Step 4: Combine Pasta and Sauce

1. Add cooked pasta to the sauce and toss until fully coated.
2. Adjust seasoning if needed.
3. Add a splash of pasta water if the sauce thickens too much.

Step 5: Assemble and Serve

1. Plate the creamy pasta and top with a seared Cajun salmon fillet.
2. Garnish with chopped parsley and extra Parmesan cheese.
3. Serve immediately while warm.

How to Serve

Serve the Cajun Salmon Alfredo Pasta hot, with the salmon placed neatly over the creamy pasta. Pair it with a light side salad (like arugula or spinach) and a slice of garlic bread for a full meal. For a special touch, drizzle a little extra Alfredo sauce over the salmon and sprinkle red pepper flakes for added spice.

Recipe Tips

• Use freshly grated Parmesan cheese for a smoother, creamier sauce (pre-grated cheese won’t melt as well).
• Don’t overcook the salmon — it should be tender and slightly flaky inside.
• If you prefer extra spice, add a pinch of cayenne or red chili flakes to the Cajun seasoning.
• To prevent the sauce from curdling, avoid boiling the cream at high heat.

Variations

• Shrimp Cajun Alfredo: Replace salmon with shrimp for a lighter, equally flavorful twist.
• Chicken Cajun Alfredo: Substitute salmon with grilled Cajun chicken breasts for a classic version.
• Vegetarian Version: Omit salmon and add roasted bell peppers, mushrooms, or broccoli.
• Lighter Option: Use half-and-half or evaporated milk instead of heavy cream to cut calories.
• Gluten-Free Option: Use gluten-free pasta or zucchini noodles.

Freezing and Storage

• Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.
• Reheating: Reheat gently in a skillet over low heat with a splash of milk or cream to loosen the sauce.
• Freezing: Not ideal for freezing due to the cream-based sauce, which may separate upon thawing. However, you can freeze the salmon separately for up to 2 months.

Special Equipment Needed

• Large skillet or sauté pan
• Medium saucepan for pasta
• Tongs or spatula for salmon
• Whisk for sauce preparation

FAQ

Q3: What can I substitute for Parmesan cheese?
Pecorino Romano or Asiago cheese makes excellent substitutes.

Q4: How can I make it spicier?
Add a pinch of cayenne pepper or extra Cajun seasoning to the salmon rub or sauce.

Yes, but add it to the dish at the end just to warm it through without overcooking.
