Notes

Recipe Yield
This recipe will yield 6 - 8 servings depending on how much everyone eats. (I like about 3 servings for myself!)
Tips
  • When using fresh or frozen uncooked green beans, make sure to cook them first or they will be really crunchy. (Blanch fresh green beans for about 5 minutes or until tender, or steam frozen beans as directed on the package. )
  • Try to use very thin green beans - frozen haricot vert or canned french cut. These will get nice and soft when cooked.
  • To make a larger batch of this recipe, double (or triple) the recipe and prepare it in a 13x9-inch (or larger for 3x) baking dish. Use an entire 6-ounce container of Crispy Fried Onions, reserving 1 ⅓ cup for the topping. Increase cooking time to 40 minutes or until heated through.
  • As a fun variation, use a mix of ⅔ cup Funyuns with ⅔ cup Fried Onions. It gives the recipe a little bit of a different flavor. (You can also do all Funyuns, about 1 ½ cups will work.) You can use the Funyuns crushed or whole!
Storage/Shelf Life/Reheating
Once cooled, store in an air-tight container in the refrigerator for up to 5 days. (It will probably last a full week, but the onions will get really soggy and the quality definitely won't be as good.)
To reheat, I recommend putting a portion in a small baking dish (like the smaller one in this set) and baking it in the oven for a few minutes at around 350°F. This will allow the crispy onions to get a little crispy again.
FAQs
Can you substitute anything for the cream of mushroom soup?
You can substitute cream of celery, cream of chicken, or cream of bacon - they are all really tasty.
Can you make green bean casserole on the stove?
You can. Just mix everything together and heat it on the stovetop, over medium/low heat, stirring pretty frequently - for about 15 minutes. Serve with crispy onions on top.
Can you make green bean casserole in the microwave?
You can, but the oven is the only way to get browned, crispy onions. To make this in the microwave, bake in a covered 1 ½-quart microwave-safe dish for 8 - 10 minutes. Stir, then top with crispy onions and cook for another minute. Let stand for 5 minutes, then serve.
Do you need to butter or spray the baking dish?
No - you do not need to grease the baking dish when making green bean casserole.
Can I make this the day before to refrigerate and serve the next day?
Yes, you can make your green bean casserole the night before and refrigerate it. Just don’t put the onions on top until you are ready to bake it. This will allow the onions to stay crispy.
Can you double or triple this recipe?
Absolutely! Be sure to use a larger baking dish and you may need to bake the casserole for an extra 5 minutes.
Can you add anything else to green bean casserole?
You can add chicken, ground beef, cooked crumbled bacon, or even cheese or water chestnuts. You can also add a pinch of celery salt or smoked salt to add a new depth of flavor.
