In a large frying pan saute in olive oil, 1/2 sweet onion sliced thin, three large cloves of chopped garlic and three slices pf bacon or pancetta chopped into pieces. Start with the bacon first to get it cooking. After all above ingredients is cooked add about 1/2 pound of cooked pasta to pan (or as much as you can fit so you can toss it) after adding pasta toss with heavy cream, about two cups and grated cheese until cream starts to thicken. I use the short curly pasta. Finish with chopped fresh parsley. Some people add eggs but I don’t. Finished dish should be nice and creamy but not too thick.
