Why You’ll Love This Recipe
Wholesome ingredients – This homemade green bean casserole is so good because it doesn’t have processed ingredients like cream of celery soup, cream of chicken soup, or french-fried onions. Everything is made with simple whole ingredients without all of the questionable additives. It is a healthy take on the not-so-healthy, classic version.
Simple and easy – This is the best green bean casserole recipe, and is one of my favorite recipes to make from scratch. Boil some green beans, fry up some onions, and throw together a creamy mushroom sauce. Then bake it all together for the tastiest dish to add to your Thanksgiving menu. The hardest part of making this dish, is refraining from snacking on all of the delicious fried onions!
Perfect side dish – Not only is this casserole dish perfect to add to your lineup of thanksgiving side dishes, it is great for any other night of the week. Pair it with a perfect roasted chicken and a salad with homemade kefir ranch dressing for a simple weeknight dinner.
Ingredients
Flour – All purpose flour is used in this recipe, but I also like to use einkorn flour in its place for the added nutrients.
Chicken Broth – Chicken broth works great in this recipe but you can also opt to make your own homemade bone broth to add more nutrients. We always like to keep some of this liquid gold on hand!

How to Make This Easy Green Bean Casserole Recipe
Step 1: Preheat oven to 400 degrees. Boil some fresh green beans for 5 minutes and then drain and place in a prepared baking dish.
Step 2: Thinly slice onions. The thinner you slice them the crispier they get.
Step 3: Preheat a cast iron skillet and add neutral oil once heated.
Step 4: To a bowl add flour, salt, garlic powder, onion powder, and fresh ground pepper. Mix together well.
Step 5: Place sliced onion into flour mixture and toss until well coated.
Step 6: Shake off any excess flour and place into hot oil. Toss with tongs until golden brown on all sides. This takes about one minute. Set aside.
Step 7: To make the sauce, heat up a cast iron skillet and add butter. Slice up mushrooms and sauté with butter in the pan.
Step 8: Sprinkle in flour and mix until there are no dry spots.
Step 9: Pour in broth and simmer for about 5 minutes.
Step 10: Add salt and heavy cream; whisk until the mixture thickens.
Step 11: Pour the sauce over the green beans and mix.
Step 12: Top with fried onions. Bake for 15 minutes.
Tips
- Slice the onions really thin, so you end up with extra crispy onions when you fry them.
- Don’t add the onions until the oil is nice and hot. I like to do one test onion to make sure before starting the cooking process.
- If you don’t have coconut oil to fry the onions, you can easily substitute it with avocado oil. I would not use olive oil because it has a much lower smoke point, and the temperature of the oil needs to be pretty hot to fry.
- Chicken broth is my go-to. Turkey broth would also work. I’ve also used beef broth, or even water with great success. You may just need to adjust the amount salt.
Recipe FAQs
This creamy green bean casserole uses a whole onion sliced up and fried, which is a great substitute for the packaged French fried onions usually used in green bean casserole recipes.
Fresh green beans are best in this classic recipe. Frozen could also be used, although it may alter the texture a bit.
If prepping your sides ahead, make the green beans and cream sauce. Allow both to cool completely. Cover the green beans in the cream sauce in your baking dish. Cover the green bean casserole well and place in the fridge up to three days. Freeze for up to two weeks.
To reheat after frozen, allow to thaw overnight in the fridge, then remove cover the next day and bake at 350 degrees Fahrenheit until hot and bubbling. While it is baking, make the fried onions. Top the casserole with the fried onions and bake for another 10 – 15 minutes. This is a great recipe to be able to prepare slightly in advance for Thanksgiving dinner.
You can store leftover green bean casserole in an airtight container in the fridge for a couple days. However, the best way to enjoy it is right away, as the onions will start to lose their crisp texture when stored.

This was a great recipe! I did sub out the heavy cream for an oatmilk creamer and used vegetable broth for family members that were vegan as well as dairy free. It turned out great!
Thank you for made from scratch recipes! Have not made this yet, but look forward to trying it now. Thanks for sharing all your recipes!!
Delicious and all homemade ingredients. It beats the soup & canned onion rings recipe by far. I will always use this recipe.
