Preheat the oven to 375. Boil chopped onion and green beans (if fresh) to soften and prepare for bake. ( See, half of these beans were dark purple before boiling, they were wild bush garden beans from my yard) *If using canned green beans then skip this step! But still preheat the oven!
Add chives, garlic, seasonings, and chopped onion to small casserole baking dish.
Pour in mushroom soup and milk. Mix well. (Here You can also substitute water for milk if you like or need to )
Add beans and mushrooms to mixture and combine thoroughly. *Here you can additionally layer the french fried onions on top before baking for added flavor and texture! Cover and Bake green bean casserole in the oven for 20-25mins while you make the stuffing on the stovetop. (Or in the microwave lol)
Follow directions on the stuffing mix box; or Boil water and butter then reduce heat to low and pour in contents of stuffing mix bag. (*Here is also where you can add in the chopped green onion) Use a fork to mix and fluff. Equally spreading around the absorption of the water. Remove from heat. Remove casserole from oven.
Scoop stuffing mix out of pan and place gently and evenly on top of green bean casserole. Bake uncovered for another 15-20 mins or until stuffing starts to become golden brown and crispy on top and the casserole is bubbly around the edges! Serve and Enjoy!
