Cook the Pasta: Bring a large pot of salted water to a boil. Add the pasta and cook according to package directions. Drain and set aside, reserving a little pasta water in case the sauce needs thinning later.

Prepare the Protein:

• In a small bowl, toss the shrimp and steak strips with ½ tablespoon Cajun seasoning.

• Heat olive oil and butter in a large skillet over medium-high heat. Add the steak strips and cook until browned and cooked through, about 3–4 minutes. Remove the steak and set it aside.

• In the same skillet, add the shrimp and cook until pink and opaque, about 2–3 minutes per side. Remove shrimp and set aside with the steak.

Make the Alfredo Sauce:

• In the same skillet, melt butter over medium heat. Add the minced garlic and cook until fragrant, about 1 minute.

• Pour in the heavy cream, Parmesan cheese, black pepper, remaining ½ tablespoon Cajun seasoning, smoked paprika, and red pepper flakes. Stir to combine and bring to a simmer.

• Let the sauce simmer for 2–3 minutes, allowing it to thicken slightly.

Combine the Pasta, Protein, and Sauce:

• Add the cooked pasta, shrimp, and steak back into the skillet. Toss everything together until evenly coated in the Alfredo sauce. If the sauce is too thick, add a little reserved pasta water to reach desired consistency.

Garnish and Serve:

• Sprinkle with fresh parsley and shredded Parmesan cheese. Serve immediately.
