Holy moly! This green bean recipe is even better than my grandma’s version

Instructions:

Preheat the oven to 350° Fahrenheit.
Melt the butter in a medium saucepan over medium heat.
While the butter is melting, add the onion and garlic to a food processor and pulse until very fine. Add the mushrooms and continue to pulse 3-4 more times.
Add the vegetables to the melted butter with the salt and pepper. Cook for 5-10 minutes, stirring occasionally.
Add the flour and cook for an additional minute, stirring constantly.
Add the stock and evaporated milk,and stir. Cook an additional 5-7 minutes or until the soup has thickened. Remove from the heat.
Place the green beans into a large, microwave safe bowl with 3 tablespoons of water and microwave for 6 minutes.
Drain the green beans and add them to a 9-by-13-by-2-inch baking dish. Cover with the mushroom soup and sprinkle with the fried onions and all of the cheese. Bake 25-30 minutes, or until the cheese is golden brown and bubbling.
