Grab a deep sided skillet that's large enough to fit the fettuccine.
Place the skillet on the stove over medium-high heat. Add milk, chicken broth, butter, and garlic. Bring to simmer and stir until the butter is melted. Then add the pasta.
Move the pasta around every 30 seconds or so until it is softened so it doesn't stick. This should take around 3 minutes. Once the pasta is softened, reduce the heat to medium and stir every couple of minutes.
After another 6 minutes or so, the pasta should be almost cooked but there should still be liquid covering the base of the skillet. Add in the cream and parmesan and mix.
Simmer, stirring occasionally, for about 2 minutes, until the sauce is thickened and the pasta is cooked. *If you cook it too long and the sauce goes gluggy, add a splash of hot tap water, it will go back to being silky with a few tosses.
Check the seasoning and add salt and pepper to taste. Serve immediately, garnished with freshly grated parmesan and parsley!
