This green bean casserole is super simple and easy to make with lighter ingredients and vegan options. There's no flour or gluten, and no crazy ingredients so you can have a delicious and healthy green bean casserole with no stress.
In a wide pot, boil the green beans for 3 minutes, then transfer to an ice bath to stop cooking. In the same pot, boil the potatoes until fork tender. Transfer to another bowl and mash with the milk until very smooth and creamy.
Drain the water from the pot and add the oil with onions and peppers on 75% heat. Cook for 2-3 minutes until the onions are translucent, then add the mushrooms, butter, and garlic. Cook until the mushrooms have wilted, then add in the mashed potatoes and parm, along with additional milk if needed. Add the salt and pepper.
In a small bowl, combine the breadcrumbs, parmesan, and oil.
In a greased 9"x 11" dish, layer the green beans and vegetables alternatively twice. Top with the breadcrumbs and bake at 400 degrees Fahrenheit for 10 minutes. Enjoy!
