For the Creamy Alfredo Sauce

Step-by-Step Instructions

1. Cook the Pasta

1. Bring a large pot of salted water to a boil.
2. Cook fettuccine according to package directions (usually 8–10 minutes, until al dente).
3. Drain and set aside, reserving 1 cup of pasta water.

2. Prepare the Steak

1. Pat the steak dry with paper towels.
2. Rub with 1 tablespoon Cajun seasoning, plus a pinch of salt and pepper.
3. Heat a skillet over medium-high heat with 1 tbsp butter + 1 tbsp oil.
4. Cook steak for 4–5 minutes per side (depending on thickness and desired doneness).
5. Remove and let it rest for 5 minutes before slicing into thin strips.

3. Cook the Shrimp

1. In the same skillet, melt another tablespoon of butter.
2. Season shrimp with the remaining Cajun seasoning.
3. Cook for 2–3 minutes per side until pink and opaque.
4. Remove and set aside.

4. Make the Alfredo Sauce

1. Using the same skillet, add 2 tbsp butter and garlic. Sauté for 1 minute until fragrant.
2. Pour in the heavy cream and bring to a gentle simmer.
3. Lower the heat and whisk in Parmesan (and mozzarella, if using) until melted and smooth.
4. Season with smoked paprika, nutmeg, salt, and pepper.
5. If the sauce is too thick, add a splash of reserved pasta water.

5. Combine Everything

1. Toss the cooked fettuccine into the creamy Alfredo sauce.
2. Top with blackened steak slices and shrimp.
3. Garnish with parsley and Parmesan.

Tips for Success

• Don’t overcook the shrimp – they only need a few minutes.

• Use smoked paprika for an extra layer of flavor.
• Add a splash of pasta water if the sauce gets too thick.
