Bring a large pot of generously salted water to a boil. Cook the fettuccine until al dente according to package directions. Before draining, reserve 1 cup of the pasta water - you'll need it later. Drain the pasta and set aside.

Heat the 2 tablespoons of oil in a large pan over medium-high heat. Add the marinated chicken and cook for 4 to 5 minutes per side, depending on thickness, until golden brown and cooked through. Remove the chicken from the pan and set aside.

In the same pan, add the butter and let it melt. Once melted, add the flour and whisk constantly for 30 to 40 seconds to cook out the raw flour taste - don't let it brown. Pour in the heavy cream and mix well.
