Cook the pasta: In a large pot of salted boiling water, cook the pasta till about a minute less than required on the packet. Reserve a cup of the pasta water and drain the rest once the pasta is cooked.
Bacon: Meanwhile, heat a large saucepan and add the oil. Bring to a medium-high heat and add the chopped bacon. Fry the bacon slowly till cooked through and nicely brown (4 to 5 minutes) Remove and set aside leaving the oil in the pan.
Garlic & Shallot: Same pan, lower the heat and cook the garlic and shallot for 2 minutes or until light golden brown.
Cream: Add the cream, half of the pasta water and cook for 2 more minutes.
Combine: Stir it in to combine, a couple seconds
Pasta water: Add the remaining ½ cup pasta water.
Simmer to reduce in necessary: If your sauce is too thin (perhaps added more than needed pasta water or trying to create more sauce) let it simmer 2 to 3 minutes to get thick again.
Cheese: Add the cheese and stir it in to melt.
Cooked pasta: Add the cooked pasta and gently stir it through. Bacon: Add the bacon.
Combine: Stir the bacon through with the pasta and cream.
Black pepper: Add fresh black pepper and extra slices of cheese to serve.
