March 10, 2022

Green bean casserole is a delicious side dish that is creamy, crunchy, and rich! Most of us eat it during Thanksgiving, but it is time for us to bring the casserole into the non-holiday season. 

With its different textures and flavors, green bean casserole may look a bit intimidating. But, this 3-ingredient casserole recipe makes it super easy to make. The recipe uses some canned ingredients, but with a bit of love and care, it tastes like it was made from scratch. 

With 3 ingredients, you can have a delightful green bean casserole without all the hassle. One bite of this simple casserole recipe will convert any green bean hater! 

How to make a creamy and crunchy green bean casserole

This 3-ingredient green bean casserole recipe is so easy to make! You really just mix the ingredients together and bake it.

The biggest tip I have when making this recipe is to only use about ⅔ of the fried onions in the casserole mix. The rest of the fried onions should be added to the top of the green bean casserole at the end of baking. This will give the dish a nice bit of crunch. 

When you are done mixing the ingredients together, bake it in the oven for 45 minutes at 350F. Sprinkle on some fried onions, and your casserole is ready to go. 

If you want the fried onions to have a more caramelized taste, put the casserole into the oven for a few minutes. This step is optional, but your casserole will taste better if you follow this step.
