If you can’t find grilling shrimp, you can use large or extra-large shrimp. Pre-cooked shrimp is fine to use if that's what you have on hand. Frozen shrimp can also be used for this recipe, but be sure to thaw and pat them dry before beginning.
You can use any kind of pasta shape you prefer for this recipe. Fettuccine, linguine, spaghetti, and angel hair are popular options.
Store leftover shrimp alfredo in an air-tight container kept in the refrigerator for up to 3 days. Reheat gently on the stovetop over medium-low heat. Feel free to add a splash of heavy whipping cream to loosen it up if needed.
