Step 1: Cook the Pasta
Boil a big pot of salted water and cook your fettuccine until just al dente. Reserve about 1/2 cup of the pasta water, then drain and set aside.

Step 2: Season and Sear the Steak
Pat your steak dry and season generously on both sides with Cajun seasoning, salt, and pepper. Heat 1 tbsp olive oil and 1 tbsp butter in a large skillet over medium-high heat. Sear steak 3–4 minutes per side for medium rare (adjust based on thickness). Let it rest on a cutting board while you make everything else.

Step 3: Cook the Shrimp
In the same pan (hello, flavor!), toss in the shrimp with a bit more Cajun seasoning. Sear for about 1–2 minutes per side until just pink and slightly crisped. Remove and set aside.

Step 4: Make That Sauce
Lower the heat to medium. Add 3 tbsp butter to the same skillet and sauté the garlic until fragrant (about 1 minute). Pour in the heavy cream and add red pepper flakes. Let it simmer gently for 3–4 minutes, then stir in the parmesan until smooth. Taste and adjust with salt and pepper. If it gets too thick, splash in some reserved pasta water.

Step 5: Bring It All Together
Toss the cooked pasta into the sauce and coat every strand. Slice the steak against the grain. Add shrimp and steak on top or gently fold them in. Let it all warm through for a minute or two.

Step 6: Serve Like a Boss
Plate it up, sprinkle with parsley, more parm, and a squeeze of lemon if you like a little zing. Light a candle or just turn on Netflix — either way, this is a moment.
