Olive Garden Fetuccini Alfredo

1/2 cup real butter
1 pint 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 fettuccini, prepared as directed
chopped fresh parsley, for garnish

In a 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.
-Serve sauce over hot fettuccine noodles and sprinkle with parsley.

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.
