This Classic Green Bean Casserole Recipe is the side dish everyone craves during the holidays. It’s simple to make but with a few tips, you can take this recipe from good to great! Let me show you how to make it.

How to make this Classic Green Bean Casserole Recipe

The first (and most important) tip I have for you is to use FRESH green beans, not canned. Canned just do not hold up in this recipe. I cannot stress this one enough.

Wash and trim the ends off of the green beans, then cut into bite sized pieces. Because we are using fresh green beans and they are a bit firm, I like to par cook these by blanching or steaming and then cool completely. They will finish cooking in the oven.

I also use mushrooms in this recipe. I’ve tried it with fresh mushrooms and I actually prefer canned. Just drain them and toss them into the undiluted Campbell’s Cream of Mushroom soup.

Add soy sauce.

And milk.

Season well with salt and pepper.

Add the cut green beans and give a good stir.

Spread the mixture into a baking dish.

To keep things traditional, I’m using crispy fried onions. These are very readily available in grocery stores nowadays. I put them on literally everything! Yummmy 🙂

I like to mix some in and place some on top. Bake until the soup is bubbling and the top is golden.

Allow the casserole to cool slight before serving. It will thicken a bit as it rests.
