Notes

Casserole Recipe Yield

This recipe will yield 6 - 8 servings, depending on how much everyone eats. (I like about 3 servings for myself!)

Recipe 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 1/3 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 1/2 cups will work.) You can use the Funyuns crushed or whole!

How to Store Leftover Green Bean Casserole

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.
