Cook pasta according to package instructions.

In a large skillet, cook the bacon until nice and crisp. Transfer to a paper towel lined plate to drain. Pour off all but 1 tablespoon of bacon fat.

Cut the chicken into bite sized pieces and add it to the hot skillet. Cook thoroughly, making sure all sides of the chicken brown. Transfer the chicken to the plate with the bacon.

In the same skillet (add olive oil if needed), sprinkle in the flour and Spicy Ranch Dry Salad Dressing mix and whisk constantly for about a minute. Pour in the milk, while whisking. Bring to a simmer and allow to cook for a couple minutes, until it thickens. Add the chicken, bacon, and Parmesan and stir until the Parmesan melts.

Once the pasta is cooked, drain it and add it to the pan with the sauce. Stir it all together and allow it to cook for an extra couple minutes just so the pasta absorbs some of the sauce. Serve with extra Parmesan.
