    Notes

    🥕NOTE: This recipe was modified 11/19/2021
    🥕You can use fresh or frozen (thawed) or canned green beans. I prefer French cut beans that are sliced lengthwise. They are more tender and cook quicker. Allow frozen green beans to thaw for 15-20 minutes before baking.
    🥕This dish can be prepared a day in advance. Pre-bake it and store covered in refrigerator. Reheat in oven (covered) at 350º for 15 minutes. Remove cover and add reserved onion rings during last 5 minutes of baking until crispy.
    🥕This dish is best enjoyed within 3 days. Store covered in refrigerator.
