Cook the pasta.
Bring a large pot of salted water to boil. Cook pasta according to package instructions, undercooking by about 1 minute (it will continue to cook a bit more in the sauce).
Combine the pasta and sauce.
Add cooked pasta to the skillet over medium low heat. Pour in Alfredo sauce and toss to combine. Don’t worry if the sauce seems thin, it will thicken as it heats up.
