This green bean casserole recipe has been a hit at our Thanksgiving. It is a variation on a Alton Brown recipe.
Do be careful with the onions. They can burn if you don’t watch them carefully. I burned a batch by using a hotter temperature from the original recipe. I also looked away for a bit. The onions turned from brown to black, and I had to start over. On my second, and successful attempt, I cut the oven temp to 350 F, used conventional vs convection heat, and checked them every 5 minutes.
