Preheat oven to 350°F

Melt Butter in large skillet or sauce pan. (must be big enough for all ingredients) Stir in flour until smooth. Cooking for 1 minute.

Remove from heat add seasoning, sour cream, cheese and green beans. Stir to coat well.

* my apologizes I am a cook who does not measure so if you dont want your casserole too creamy only add sour cream to your liking*

Pour mixture in a casserole pan. (I love cheese so I cover with more cheese) Top with fried onions.

Bake covered for 20 minutes, remove cover and bake an additional 20 or until golden brown and bubbly cheesy.

Stand back and watch them ENJOY!!!
