Pre-heat your oven to 400ºF (200ºC).
Over medium-low heat, melt the butter in a large 10-inch ovenproof skillet.
Add minced garlic and cook, stirring occasionally until the garlic is fragrant (make sure not to burn the garlic).
Add the chicken broth and simmer for 3 minutes, then add the cream.
Cook, stirring occasionally until the mixture is thickened – about 5 minutes or maybe more if you prefer a thicker sauce.
Season with salt, pepper and Italian seasoning.
Remove the cream sauce from the heat and add the green beans.
Give it a nice stir, combining the sauce and beans.
Bake the green bean casserole until bubbly, about 10-15 minutes.
Remove from the oven and top with parmesan and bacon.
Toss to combine and transfer to a serving plate or bowl, then serve the green bean casserole with bacon and parmesan immediately, or reheat as desired.
