Let’s make a tradition in our house on Thanksgiving: Green Bean Casserole!

Growing up, my Mom made this every Thanksgiving. We looked forward to it every year. It was our favorite! My Mom has to make this or people complain… they are up in arms!
Now that I’m an adult, I realize this side dish doesn’t have to only be for Thanksgiving. You can make this anytime you want! It makes an excellent side for any occasion. It is so easy there’s just a few ingredients.
Green Bean Casserole | Recipe
So we have have two cans of condensed cream of mushroom soup, fresh mushrooms, we have some green beans, we have a little bit of milk (especially if you have condensed soup), and then some organic french fried onions for the top. And that’s pretty much the whole thing. It’s so easy to make.
In a mixing bowl, add a half a cup of milk.. any kind of milk you want, and then you’re just going to stir it together nicely.
My sister Suzanne has added her own touch to the recipe over the years, by adding fresh sliced mushrooms into the cream of mushroom soup… a genius idea and so easy to accomplish, especially if you buy pre-sliced fresh mushroom! Just wash your sliced mushrooms and mix them in!Â

Next up is the green beans. We like to buy frozen French sliced green beans. We think they’re the most delicious. You can do them canned, you can do them frozen, you can do them fresh. It’s whatever you prefer (and whatever you have time for really, especially if you’re preparing a whole Thanksgiving meal alongside this side dish!)
We place the green beans in a large casserole dish and spread them on evenly.
Preheat the oven to 350°F at this point, because this next part will go really fast.
Now, take this beautiful mixture of the soup, the milk, and the mushrooms and you just pour it in on top of the green beans, spreading it out evenly. Then you just just mix it up.
When everything’s nicely together, then we have some french fried onions to top everything off. We’ll put the whole can on  (the more the merrier!) Â
Spread it to the sides a little bit so the top is evenly covered.
Now you pop it into the oven at 350 degrees F for 30 minutes or until it’s it starts to bubble.
When we check on the casserole, it’s bubbling beautifully, so it’s ready to come out.
Let it cool for just a minutes or two, then it’s ready to plate up and enjoy
