                Toss in the parmesan and cheddar cheese, mixing everything so it's evenly spread out.

                Spread the biscuit batter over your green bean mixture in the dish as evenly as you can.

                Combine the biscuit mix seasoning packet with your melted butter while the dish is baking.

                Once it’s out of the oven, coat the top with the seasoned butter using a brush.

                Let everything sit for at least 5 minutes so it can soak in the butter topping.
