This was a hit a Thanksgiving dinner tonight. Just one suggestion- use equal parts butter and flour (increase the butter to 3 tbsp) for the roux ;otherwise, prepare to smash up a lot of lumps of flour. Thanks for posting- I'll be forwarding it on.
This is a very tasty casserole. The sauce is creamy, the mild green chiles add a nice touch and the topping is crisp. I served it for Thanksgivings and everyone gave it 5 stars. Thanks for sharing.
I admit it, I enjoyed this green bean casserole even more than my own recipe - the white sauce is better and the crumb topping is lighter and tastier than the crust in my version. This one is a winner!
