Fettuccine Alfredo like Olive Garden's

1/2 cup real butter
1 pint (2 cups / 16 fl. oz.) heavy whipping cream
1 tsp. garlic powder
salt and pepper - to taste
1 dash cayenne pepper
2/3 cup fresh grated Parmesan OR Romano cheese
1 lb. box fettuccine noodles - prepared as directed
chopped fresh parsley - for garnish, optional

-In a 2-quart saucepan over medium-low heat, melt butter; add cream, garlic powder, and salt and peppers; simmer for 20-30 minutes, stirring constantly, until thick.
-Remove sauce from heat and stir in cheese. Do not heat sauce after cheese has been added.
-Serve sauce over hot fettuccine noodles and sprinkle with parsley, if desired.

Notes: Though you can’t rush this sauce, if it seems to be taking too long to thicken, stir in up to 1/4 cup cream cheese. Make sure your Parmesan or Romano is grated and not shredded; it won't melt properly if shredded. Do not use Kraft® Grated Parmesan in the canister; your Alfredo won't taste right. Either grate your own or buy the stuff from the deli.
