FOR THE ALFREDO SAUCE:
In the same skillet, melt the butter over medium-low heat. Once the butter is melted, add the cream cheese and heat until softened.
Pour in heavy cream and season with Cajun spice, salt, and pepper. Whisk to combine.
Bring to a low boil. Once boiling, decrease the heat to low and allow the sauce to simmer for 8-10 minutes, whisking occasionally. The sauce should be thick enough to coat a spoon.
Once the sauce has thickened, turn off the heat and add the parmesan. Stir until cheese is melted and combined. Taste the sauce and adjust the seasonings to your preference.
Add the pasta and toss it around to coat in the Alfredo. Toss in the steak, and shrimp and stir to combine. Serve and enjoy!
