Tips & Variations
- Any style of green beans works well, but French cut green beans add a nice texture.
- For a richer taste, use whole milk or even half-and-half instead of skim milk.
- Add sautéed mushrooms or chopped water chestnuts for extra flavor and crunch.
- To make it vegetarian, check the soup label or use a mushroom-based vegetarian cream soup.
Storage
Green bean casserole can be made ahead and frozen. Assemble the casserole without the crispy fried onions on top, wrap it tightly in plastic wrap, then cover with foil. Freeze for up to two weeks. When ready to use, thaw in the refrigerator overnight, then bake as directed and add the fried onions before the final baking step. Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven for best texture.
