Alright, here goes my green bean casserole recipe...
Chop up a half white onion finely. Saute over medium heat until translucent in 3 tablespoons of butter. Add two tablespoons of flour and cook for several minutes until you've got a very light roux going.
Add the following to the skillet: 1 cup of sour cream, 1/2 tsp of salt, 1/2 tsp of black pepper, 1 tsp of sugar and 2 tsp of garlic powder. Stir frequently until well combined.
Remove from heat and transfer to a large mixing bowl. Stir in 4 cans of French cut green beans (drained), a cup of grated cheddar, and about a half a container of French fried onions crushed. Mix all of that very well and then transfer to a 13x9 casserole dish. Top it with another cup of shredded cheddar once in the casserole dish.
Finally, crush about 1/2 sleeve of Ritz crackers and remaining French fried onions in a bowl, and melt two tablespoons of butter. Add the butter to the cracker mixture and blend well. Spread this evenly on top of the casserole dish. If the mixture produces too much, don't overdo it. Should be a relatively thin layer that covers the whole dish.
Bake at 350 for about 30 mins, until the top is golden brown. Let it sit for 10 mins or so before digging in.
Thank me later.
