Cook fettuccine according to directions. In large saucepan, saute onion and garlic in butter til tender. Stir in flour until well blended. Gradually stir in cream. Bring to a boil over medium heat, stirring constantly. Add broccoli. Reduce heat, simmer, uncovered, for 15 minutes or til broccoli is tender-crisp, stirring occasionally.
This was a first time recipe - and it is definitely a keeper. It was yummy and fresh broccoli was a nice addition. I love a good alfredo sauce and this was good and easy.
