Cook the bacon in a large skillet over medium-high heat until crispy. Transfer to a paper towel-lined plate, let cool slightly, and chop.
In a large bowl, stir together the cream of mushroom soup, milk, salt, pepper, and soy sauce. Stir in half of the cheddar cheese and half of the cooked bacon.
Add the frozen green beans and half of the French fried onions. Stir until well combined.
Spread the mixture evenly in a casserole dish.
Bake for 30 minutes. Stir, then top with the remaining bacon, cheddar cheese, and French fried onions.
Bake for an additional 10 minutes, until heated through and the cheese is melted.
Serve and enjoy!
Notes
Refrigerate the leftovers in an airtight container for up to 5 days.
