Green Bean Casserole + Homemade Cream of Mushroom Soup

Green Bean Casserole is a classic Thanksgiving side dish that everyone loves! Fresh green beans mixed with homemade cream of mushroom soup and topped crunchy french fried onions then baked until golden and bubbly makes the perfect accompaniment to any holiday meal.

I didn’t have Green Bean Casserole for the first time until I was 13 or 14, (I’m originally from Canada, and 20 years ago, this classic American dish wasn’t even heard of, let alone found on any holiday table) when a family friend from America came to visit us for Canadian Thanksgiving.  They wanted to share a dish for dinner, and this was it.  They used canned green beans, a can of cream of mushroom soup and a whole heap of french fried onions.  It was absolutely delicious, and I think I asked my Mom for it at least once a week for the next few months.

We continued making Green Bean Casserole this way, and Mom still does, and it’s still the classic comfort food I remember as a kid, and love to this day.  But, classic Green Bean Casserole is not healthy.  It has a lot of processed ingredients in it, sometimes giving it that ‘canned’ taste.  I wanted to change up the recipe to make it a little healthier.  I still use the french fried onions, but I now use fresh green beans and Homemade Cream of Mushroom Soup.

What really makes Green Bean Casserole shine is fresh green beans.  Tim and cut green beans into thirds, and cook for 5 minutes in boiling salted water.  Drain, and set aside to cool.  To make Thanksgiving, or any meal prep easy, you can cut and blanch the green beans up to a week in advance.

What makes good Green Bean Casserole great is the Homemade Cream of Mushroom Soup.  It’s really easy to get started, and other than mushrooms, you probably already have everything you need already in your fridge and pantry.  We use cream of mushroom soup in so many different recipes (like Tatertot Casserole), that it’s something I always have prepared and ready to go in the fridge or freezer.  Making the soup is simple, and comes together in 15-20 minutes, and you can use it in casseroles, or enjoy it on its own as a bowl of soup. Cream of mushroom soup can be made up to a 4 days in advance, or before if you freeze it.

Using fresh green beans was my first step in recreating the classic recipe, and makes the biggest difference in the recipe.  If you’re not ready to take the plunge and make Homemade Cream of Mushroom Soup, start with the fresh green beans.  It’ll be worth every second of the extra 10 minutes it takes to prepare.

The best part about this Green Bean Casserole is that it’s another easy Thanksgiving recipe that you can make ahead of time, and just assemble and bake on Thanksgiving Day.  A couple days ahead of time, you can prepare the filling, and cover with foil, label it, and put in the fridge.  Right before baking, top with the french fried onions, and in 15 minutes, you’ll be enjoying a hot, bubbly, crispy Green Bean Casserole.
