Start by putting the spaghetti to boil.
While they are boiling, start preparing the carbonara sauce.
In a pan put the bacon together with the garlic-infused olive oil. And fry it over medium heat for about 5 to 8 minutes, or until the bacon starts to become crispy.
Once the bacon is cooked, take it out and in the same pan add the cooking cream and the cheddar and parmesan cheese. (Don't discard the oil left in the pan from the bacon, cook the cream in the oil, that gives all the amazing flavor!)
Simmer the cream for about 6 to 7 minutes over medium heat. Once it starts to thicken, take it off the heat.
Drain the spaghetti and mix them together with the cream and the cooked bacon.
Serve it with some freshly grated parmesan.
