Start by frying your bacon until it’s nice and crisp. Once cooked, chop it into pieces and set aside — you’ll use most in the mix and some for topping.
In a large bowl combine the cream of mushroom soup, milk, softened cream cheese, and pepper. Stir until mostly smooth (you’ll be okay if there are a few small chunks).
Drain the green beans and add them into the creamy mixture. Stir in about two-thirds of the fried onions and about one-third of the chopped bacon.
Spread the mixture into your baking dish and bake at 350°F for 30 minutes. Then remove it, sprinkle the remaining bacon and onions on top, and bake another 5 minutes until the onions are golden.
