In a large pot, bring salted water to a boil. Add the fettuccine pasta and cook according to package instructions until al dente. Drain and set aside.
In a bowl, toss the shrimp with Cajun seasoning until evenly coated.
In a large skillet over medium heat, add the olive oil. Once hot, add the seasoned shrimp and cook for 2-3 minutes per side until they turn pink and are just cooked through. Remove the shrimp from the skillet and set aside.
In the same skillet, add minced garlic and diced bell peppers. Sauté for about 2 minutes until fragrant. Then, pour in the heavy cream and bring it to a gentle simmer.
Gradually whisk in the grated Parmesan cheese until melted and creamy. Season the sauce with salt and pepper to taste.
Add the cooked fettuccine and shrimp back into the skillet with the Alfredo sauce. Toss everything together until the pasta is well coated in the sauce.
Stir in chopped green onions and let everything heat through for another minute.
Plate the Cajun Shrimp Alfredo Pasta in bowls and garnish with fresh parsley for an added pop of color.
