Cook pasta according to package directions.  While pasta is cooking, place bacon and onion in a 12 inch skillet on medium heat.  Cook until the bacon starts to turn crispy - about 5-7 minutes.

Add cream and stir until it begins to boil.  Add Parmesan cheese and stir until the cheese is melted.  Add salt and pepper to taste.

When pasta is drained, return to the pot you cooked it in or put in a large serving bowl. Pour sauce over the top and stir to coat pasta. Serve with your favorite vegetable or salad and enjoy!
