With perfectly cooked pasta, tender leftover steak, and Alfredo sauce with my secret ingredient, you'll be making this again and again!
Set a skillet over medium heat and melt butter. In a separate pot, cook a package of pasta.
When the butter is fully melted, add in garlic, and cook for 2-3 minutes while stirring, or until fragrant.
Slowly add in the heavy cream, stirring constantly so the cream doesn't curdle.
Sprinkle in the Parmesan slowly, while stirring constantly to avoid clumps.
Add in the slices of American cheese and stir until fully incorporated.
Sprinkle with pepper and stir to combine.
Add in the pasta and sliced steak. Top with extra Parmesan and parsley as desired, and serve!
