Set your oven to 350°F (175°C). Lightly coat a 9×13 baking dish with non-stick spray.

In a big skillet over medium heat, cook the ground beef and onions until browned. Break the meat apart as it cooks. If there's leftover grease, drain it. Stir in the cream of mushroom and cheddar soups, milk, salt, and pepper. Mix well, then add half of the shredded cheddar cheese, letting it melt as you stir. Turn off the heat.

Spread the beef mixture evenly into the baking dish. Sprinkle the other cup of cheddar cheese over the top.

Stir together the biscuit mix (only the mix, not the seasoning!), milk, and shredded cheddar in a bowl until all lumps are gone. Pour this mixture over the beef layer.

Put the dish in the oven and bake it uncovered for about 50 to 55 minutes. It’s ready when the biscuit topping turns a golden brown tone.

Blend the melted butter with the included seasoning packet in a small bowl. Once the casserole is out of the oven, brush this butter mixture over the biscuit crust. Let everything settle for 5 minutes so it thickens. Sprinkle parsley on top if you’d like before serving it up warm.
