This is another simple yet tasty side dish. Please feel free to use any dried herb that you like in place of the basil. Sometimes I even add a few shakes of crushed red pepper flakes to give a little "heat" to the beans. If you'd like to cut back a little on the olive oil, a few tablespoons of water in the bottom of the pan will keep the beans from drying out too much.
This may be served hot as a casserole or reduce the melted butter amount down to 2 tablespoons and serve as a cold potato salad, either way it's delicious! --- If you are serving hot as a casserole I strongly recommend to have the potatoes cooled to room temperature before using in this recipe or use cold potatoes that have been cooked a day ahead, I have even made this using about 5 cups of thawed frozen hash browns, the complete casserole may be assembled and refrigerated for up to 2 days ahead before baking although it's so delicious cold it might not even make it to the oven, and also makes a large amount which makes this *perfect* dish for potlucks --- if you are baking as a casserole use only mayonnaise such as Hellman's using salad dressing will not be as good.
My mother has been making this recipe for years. Its quick and easy and comes close to the original. I am not a big fan of the "chile". I have substitued chopped green chiles and shredded the jack cheese - which I actually prefer - but either way, this is a tasty one!
