While shrimp is baking, cook pasta in a large pot according to package directions. Fresh broccoli can be cooked with the pasta during the last two minutes of pasta cook time. For frozen broccoli, prepare according to package directions.
In a saucepan, cook remaining fettuccine alfredo ingredients on low heat until cream cheese is completely blended and mixture is mixed well.
Once pasta is done drain and return to pan. Add sauce and stir to coat evenly. Add cooked pasta, broccoli and shrimp. Serve.
