Have you ever made southern green bean casserole from scratch?

Store bought ingredients do have their time and place when looking for a quick cooking solution. However, a little extra effort can yield incredible homemade dishes your family will love. You will be amazed at how easy making your favorite dishes from scratch can be.

Make Holiday Cleanup and Storage Easier

When it comes to cooking and baking, I always like to use oven safe, glass baking dishes, especially for casseroles.

For this recipe I recommend using a glass baking dish with a storage lid. I have used these glass baking dishes for years. Not only have they held up well but when it comes to storing leftovers in the fridge, nothing is easier than just snapping the lid on the container.

When your baking dishes have storage lids you don’t have to mess with aluminum foil and plastic wrap which reduces waste and helps out the planet.

  • In a sauce pan. Add green beans and cover with water.

  • If using store bought French fried onions, sprinkle on top of baked green beans, return back to the oven to bake for an additional 15 minutes or until onions have crisped up and browned a bit.
  • If using regular soy sauce, eliminate the salt.

  1. Do you think you can make this a day ahead?

    1. Like with my baked macaroni and cheese recipe you can assemble the green bean casserole the day before and then bake it the next day.

      What I would do would be to do all of the steps up until it is time to bake. Put it in a disposable aluminum pan in the fridge overnight and then the next day bake the assembled green bean casserole in the oven a little longer than recommended. You will need to add an additional 10-15 minutes to your cooking time to account for the fact that the green bean casserole is cold from the fridge when baking it the next day. While the green bean casserole bakes, I would then prepare the homemade french fried onions to add to the top once it is done baking.

      Please keep in mind that if you are assembling the day before and baking the next day cold from the fridge – do not use a glass baking dish! You will need to use a metal or disposable aluminum pan because glass will shatter if it goes from really cold to really hot temperatures quickly.
