- 8 oz crab meat
- 1 salmon fillet, cooked and flaked

How to Make Cajun Lobster Crab and Salmon Alfredo
Step-by-Step Instructions
Step 1: Prepare the Pasta Cook the fettuccine according to package directions until al dente. Reserve 1 cup of pasta water before draining. Set the cooked pasta aside while you prepare the sauce.
Step 2: Create the Alfredo Base In a large skillet or saucepan over medium heat, pour in the heavy cream and bring to a gentle simmer. Add the minced garlic and cook for 1-2 minutes until fragrant, being careful not to let it brown.
Step 3: Build the Sauce Gradually whisk in the grated Parmesan cheese, allowing it to melt completely before adding more. Continue stirring until the sauce is smooth and creamy. Season with 1 tablespoon of Cajun seasoning, salt, and pepper to taste.
Step 4: Add the Seafood Gently fold in the cooked lobster pieces, crab meat, and flaked salmon. Sprinkle the remaining tablespoon of Cajun seasoning over the seafood and stir carefully to avoid breaking up the delicate pieces. Cook for 2-3 minutes until the seafood is heated through.
Step 5: Combine and Serve Add the cooked pasta to the skillet and toss gently to coat with the creamy sauce. If the sauce seems too thick, add reserved pasta water a little at a time until you reach your desired consistency. Taste and adjust seasoning as needed.
Step 6: Garnish and Plate Transfer to serving plates and garnish with chopped green onions or fresh parsley. Serve immediately while hot.
Helpful Tips
Seafood Selection: Use high-quality, fresh or properly thawed seafood for the best flavor and texture. If using frozen crab meat, ensure it’s completely thawed and drained of excess moisture.
Cajun Seasoning Balance: Start with less Cajun seasoning and taste as you go. Different brands vary in heat level, so adjust according to your preference and tolerance for spice.
Pasta Water Magic: The starchy pasta water is crucial for achieving the perfect sauce consistency. Don’t skip reserving it before draining your pasta.
Gentle Handling: When folding in the seafood, use a gentle touch to prevent the delicate pieces from breaking apart and maintain the dish’s elegant presentation.
Temperature Control: Keep the heat at medium or medium-low when making the sauce to prevent the cream from curdling or the cheese from becoming grainy.

Notes

Seafood Substitutions: If lobster is unavailable or too expensive, you can substitute with additional crab meat or cooked shrimp. Similarly, any firm white fish can replace the salmon if preferred.
Pasta Alternatives: While fettuccine is traditional for Alfredo, penne, rigatoni, or even linguine work well with this sauce. Choose a pasta shape that will hold the creamy sauce effectively.
Make-Ahead Considerations: This dish is best served immediately after preparation. The cream sauce doesn’t reheat well, so plan to serve it fresh from the pan.
Spice Level Adjustments: For a milder version, reduce the Cajun seasoning to 1 tablespoon total. For more heat, add a pinch of cayenne pepper or hot sauce to taste.
Wine Pairing: This rich dish pairs beautifully with a crisp white wine like Chardonnay or Sauvignon Blanc, which complements the seafood without competing with the bold flavors.
