Variations & Tips
For a lighter version, you can substitute half-and-half for the heavy cream. If you have picky eaters, consider adding some cooked peas or spinach to the pasta for added nutrition. For those who enjoy a bit of spice, a pinch of red pepper flakes in the sauce can add a nice kick. You can also use whole wheat fettuccine or gluten-free pasta to suit dietary preferences.
