Creating Cajun Shrimp and Steak Alfredo Pasta is a breeze if you follow these simple steps:

1. Cook the Pasta: In a large pot, bring salted water to a boil. Add fettuccine and cook according to package instructions until al dente. Drain and set aside.

2. Prepare the Steak: Season steak strips with salt, pepper, and half of the Cajun seasoning. In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Sear the steak for 3-4 minutes, cooking to your preferred level of doneness. Remove from the skillet and set aside.

3. Cook the Shrimp: In the same skillet, add the remaining olive oil and shrimp. Sprinkle with the remaining Cajun seasoning. Cook for 2-3 minutes on each side until shrimp are opaque and cooked through. Remove and set aside.

4. Make the Alfredo Sauce: In the same skillet, reduce the heat to medium. Add butter and minced garlic, sautéing until fragrant, about 1 minute. Pour in the heavy cream and stir, allowing it to simmer for 2-3 minutes.

5. Incorporate Cheese: Gradually stir in the grated Parmesan cheese, mixing until the sauce is smooth and thick, about 2-3 minutes. Adjust seasoning with salt and pepper if needed.

6. Combine Pasta and Sauce: Add the cooked fettuccine to the skillet with the Alfredo sauce, tossing to coat the pasta thoroughly.

7. Add Steak and Shrimp: Gently fold in seared steak and cooked shrimp until well distributed throughout the pasta.

8. Serve Hot: Remove from heat and garnish with chopped parsley for a touch of freshness. Serve immediately and enjoy!
