Notes
- Feeding a crowd? Double the ingredients and use a 9×13 baking dish. Stir about a quarter of the crispy onions into the green bean mixture before baking, and add about 5 minutes to the initial bake time before adding the remaining onions on top.
- Try the same method with thawed broccoli or other vegetables that pair well with Alfredo sauce.
- To make this casserole more of a main dish, stir in shredded rotisserie chicken or cooked sausage.
