Green Bean Casserole is a classic! It’s a recipe my mom made every holiday and one of my favorites.

Then though growing up my mom never put the French-fried onions on top since she never liked them.

After I was married though my husband suggested that I add them as his mom did and we LOVED it with them.

Something about the crunch that makes it taste so good.

This recipe is nothing fancy and it’s really simple to make but it tastes amazing. Make this as a side for my Slow Cooker Turkey Breast or make it every Thanksgiving as I do!

How to make Green Bean Casserole:

This recipe is the most basic green bean casserole, but it still tastes amazing.

It’s simple to make and totally foolproof. It’s honestly one off my favorite ways to make it.

You only need three simple ingredients plus some seasonings to make this dish!

Ingredient Notes:

  • French style green beans: You could use any style but after testing I found the French style to taste and bake the best. I used them out of the can and drained the water in the can.
  • Cream of mushroom soup: You can sub this for a homemade version of cream of mushroom soup. You can also use cream of chicken or celery for the same texture, but you will get a very different taste.
  • French fried onions: I used an entire jar on top for this recipe.
  • Spices: I used Onion Powder, Garlic Powder, Salt and Pepper. You do not have to use these with the cream of mushroom soup if you do not want to!

Directions:

Step one: Preheat your oven and then prepare a casserole dish. I used a 9×13 casserole dish. 

Step two: Open your green beans and drain the water. Next mix green beans and cream of mushroom soup together.

Step three: Next add in seasoning and mix again.

I used about 1/2 teaspoon of salt and 1/8 teaspoon of pepper, but you can add these to taste.

Step four: Add this to the casserole dish and top with French fried onions. We used the entire 6 oz on top.

I like to keep them crunchy and find that mixing them in gets them soggy during baking.

If you prefer you can mix these into the casserole dish and bake.

Step five: All you need to do now is bake.

I baked mine for about 20 minutes until the casserole was warm throughout.

Cooking Tips:

Here are some helpful tips when making this green bean casserole.

Mixing:

When making this casserole I like to mix my green beans and soup together in a mixing bowl then adding it to the casserole dish.

This dish can get pretty messy to mix inside the casserole dish.

The messy sides usually tend to burn so mixing it a bowl will help with that.

Make Ahead:

This dish makes the perfect side for a big family dinner or holiday dinner.

It’s so simple to make the day of but you can mix up the day before if you need to.

Prep: I would mix and cover and place in the fridge overnight to bake in the morning.

Tip: I would not add the French-fried onions until it’s time to bake to make sure they do not get soggy overnight.

Baking: If you are leaving it in the fridge overnight, I would add an additional 5 minutes for cooking.

History of Green Bean Casserole:

Did you know this recipe was created by Campbell Soup Company in 1955?

It has been a staple at Thanksgiving Dinner’s since then, and the recipe has not changed!

Three simple ingredients and you have an American Side Dish tradition ready to go!

What substitute for Cream of Mushroom Soup can I use?

Some people are allergic to mushrooms or just do not like them.

There are a few different options to use if you do not want to use Cream of Mushroom soup.

  1. Golden Mushroom Soup – a soup offered by Campbell’s that is dairy free, but still has that great mushroom flavor.
  2. Cream of Celery Soup – for those of you who do not like mushrooms or the flavor of mushrooms.
  3. Cream of Chicken Soup – this is just a basic cream soup that would be fine to use.

Can you freeze Green Bean Casserole:

This recipe can easily be frozen. Mix your ingredients together and place in a freezer safe container or casserole dish with a lid.

Do not add the French Fried Onions if freezing. When ready to bake pull it out of the freezer and thaw in the refrigerator for about 24 hours to fully thaw.

Bake as the directions say, but you may need to add 5 or 10 minutes if it is still frozen.
