Forget about the canned mushroom soup and French’s French fried onions with enough fat to bring on a heart attack. This year, impress the fam by whipping up that famous casserole side dish from scratch. Here’s how I do it.
Classic Green Bean Casserole
Serves 10 to 12. Adapted from Cook’s Illustrated
The components of the casserole can be prepared ahead of time. Combine the beans and cooled sauce in a baking dish, cover with plastic wrap, and refrigerate for up to 24 hours. To serve, remove the plastic wrap and heat the casserole in a 425-degree oven for 10 minutes, then add the topping and bake as directed. This recipe can be halved and baked in a 2-quart (or 8-inch-square) baking dish. If making a half batch, reduce the cooking time of the sauce in step 3 to about 6 minutes (1 3/4 cups) and the baking time in step 4 to 10 minutes.
