Green bean casserole is probably my favorite Thanksgiving dinner dish of all time. Unfortunately, cream-of-mystery-franken-foods-soup is not healthy. Neither are the french-fried onions that typically grace the top of this casserole. (Note: real onions don’t turn crispy when fried by themselves … I tried … they burn)

This was one of my most requested recipes, and I’m happy to share the healthy version. I think I actually prefer this one to the processed version, though it’s been so long that I don’t completely remember how that one tasted. Either way, this one is good! It’s also free of mystery ingredients!

The Best Green Bean Casserole Recipe

The classic green bean casserole features Campbell’s canned soup and mushy canned green beans. Then the whole thing is topped off with crispy fried onions. Some conventional fried onions in a can surprisingly have fairly decent ingredients, but most still have all-purpose flour so they aren’t gluten-free. Making green bean casserole from scratch isn’t just healthier, but it tastes so much better!

It is a little time-intensive to make, but is worth the effort. You can even make it ahead of time to make prep time faster on Thanksgiving. See the directions below the recipe to make this veggie casserole dish ahead.

Prepping the Green Beans

You can use the typical canned green beans in this recipe, but I really prefer fresh. They’ll take forever to cook in the oven if they aren’t precooked though and by then the onion topping will be burnt. I’ve found that the easiest way is to lightly steam them before I add the mushroom sauce.

Another option some people like is to blanch the green beans in a large pot of boiling water and then put them in ice water in a large bowl.

If you can’t find fresh green beans frozen will also work. Lightly cook them and then drain before adding the mushroom sauce.

A Faster Option

Since originally writing this recipe, I discovered an easier way to make cream of mushroom soup at home. It reduces the time needed to make this recipe. If you opt for this version, just use the homemade cream of mushroom soup in whatever green bean recipe you use (though no need to dilute half and half with water like the canned versions).

If you’re looking to save even more time, you can always use Kettle and Fire’s Mushroom Bisque soup. It’s an amazing option to homemade and tastes great!

Servings

Ingredients

Onion Topping

  • 3 medium onions (thinly sliced)
  • 2 eggs
  • 3 TBSP heavy cream (or coconut milk)
  • 2-3 TBSP coconut flour
  • ½ cup coconut oil (or tallow)

Healthy Cream of Mushroom Sauce

  • ½ cup butter
  • 10 mushrooms (finely diced)
  • ½ cup cream (or coconut milk)
  • 4 egg yolks
  • ½ tsp garlic powder
  • salt and pepper to taste
  • of onion topping mixture from above
  • heavy cream or coconut milk (or water)

Other

  • 2 pounds fresh green beans (or 5 cans or 2-3 bags of frozen)

Instructions

For Onion Topping

  • Put the sliced onions, eggs, and heavy cream into a medium-sized bowl and mix until evenly incorporated.
  • Add the coconut flour and mix by hand until evenly coated.
  • Put coconut oil (or tallow) in a large skillet and turn on medium heat.
  • When hot, add the coated onions and evenly brown, turning occasionally.
  • When browned, remove from heat and set aside.

For Mushroom Sauce

  • In a medium saucepan, melt the butter.
  • Add the diced mushrooms and sauté until starting to brown.
  • Add cream or coconut milk.
  • Whisk in egg yolks and spices and about 1/3 of the onion topping mixture (save the rest for the end) and continue stirring until the yolks begin to cook and the mixture thickens.
  • If needed, add extra milk or water to the mushroom cream sauce to thin.

Assemble

  • Preheat oven to 325°F.
  • Lightly steam the green beans and drain to remove excess liquid. If you’re using canned green beans then drain off the liquid. Place the green beans into a 9×13 baking dish.
  • Pour the cream mixture over and mix until incorporated.
  • Top the green bean mixture with the remaining onion topping mixture and heat in the oven until the topping starts to crisp (but not burn!) and the green beans are heated.

How to Make Green Bean Casserole Ahead of Time

To make this ahead of time make the recipe according to the directions above, but don’t add the onions to the top. Refrigerate for up to several days until ready to eat. Let the casserole come to room temperature before putting it in the oven or the cold casserole dish could explode in the hot oven. Add the onions to the top and reheat in the oven until the topping is golden brown and crunchy.

    How would a prepared soup substitute into this recipe? Just replace the whole sauce making step?

    Found a great recipe last year at The Kitchn.com for the casserole. I substituted sweet rice flour for the all purpose. Gluten Free Crisp French Fried Onion Toppibg recipe from TheCountryBasket.com.
    Preparing the mushroom bechamel takes some time but well worth it!

    Hi there, love your blog! Got a question on this one. I have a family member that cannot eat mushrooms, I found a recipe to make cream of chicken sauce. After it is made, how much of that would I add to the beans to finish the casserole? Thanks in advance!

    I made a mistake when I made this recipe, but it still turned out excellent. My husband said I need to mess it up every time. So I was making this for Thanksgiving, and making your stuffing recipe at the same time. I had mixed up the stuffing spices ahead of time, and when I got to step 8 in the beans recipe to “add spices” I threw in the stuffing spices without thinking. I went with it anyways, and the spice mixture in the green bean casserole was perfect!

    Hi Katie, my husband and I are working on making the switch to healthy food with out family, and I love your blog, thanks for sharing your knowledge and insights. Where do I find Healthy Cream of Mushroom Sauce? Can I make it myself and do you have a recipe for it?

    1. Liz Avatar

      Rebecca, Im guessing that the “Healthy Cream of Mushroom Sauce” would be all the ingredients she listed under that title.
      Healthy Cream of Mushroom Sauce
      •½ cup butter
      •½ cup cream or coconut milk
      •? of onion mix above
      •8-10 mushrooms, finely diced
      •½ tsp garlic powder
      •salt and pepper to taste
      •4-5 egg yolks (You should have these left over if you are making the Sweet Potato Casserole)
      •coconut milk or water to thin

    I would like to make this for family get-togethers, but my niece and nephew are both allergic to eggs & dairy.

    What do you think would be an adequate substitute (if any exists) for the eggs in this recipe? Also instead of butter, I suppose it wouldn’t make any difference if I used margarine. I normally dislike margarine, but I have no other options when cooking for family parties because of their allergies.

    Thanks so much!

    I would like to try this too for my mom..she will love it ..thanks for such a good recipe.

    We made this for Thanksgiving, and I couldn’t believe how much it tasted like the “original” processed food version. Delicious!!!

    1. Brendark Avatar

      Also curious… I’m all paranoid I’m going to get sidetracked and burn it… :/

    Do you think I could use coconut oil in place of the butter in the cream of mushroom sauce? I can’t have any form of dairy, unfortunately, so I’m wondering what could be a good substitute. Would coconut oil alter the taste/texture too much???

    I am a green bean casserole junkie and I am excited to give this non-processed version a try. And if I’m the only one who likes it, more for me! (Though I highly doubt I will be). Thank you so much for this recipe!!

    I made this dish for Thanksgiving but I made one crucial error; I did not temper the egg yolks with a little bit of the warm sauce from the pan before adding them and the result was more like scrambled eggs than a cream sauce – WOOPS! I’m trying again on Sunday for Christmas dinner. Wish me luck and THANK YOU for this recipe!

      Oh boy. I think I just made this same mistake. But I’m sure it will still taste good!

    Hello Wellness Mama, Where can I find Tallow oil and what is the difference in that and the coconut oil? I’m trying this receipe for Thanksgiving.

    Thanks

      Tallow is basically just beef fat but butter or coconut oil would also work well

    Do you think you could prepare this the night before and then just bake it Thanksgiving day?

      Wellness Mama

      I would think so… the leftovers reheated great the next day, so making it ahead of time should be fine!

    about how many pounds of fresh greenbeans would you use to replace the cans?  I REALLY don’t like canned greenbeans.

    1. Wellness Mama Avatar
      Wellness Mama

      I’d guess about 2 pounds, though I’ve canned all the ones from our garden this year, so I haven’t used fresh in a while.

    Thank you for these Thanksgiving recipes.  I thought I was going to have to search everywhere for my Thanksgiving recipes, but knowing I can find them all here is soooo helpful! My mom will still be making her version of things…but at least I’ll have things to eat and maybe I can convert a few family members when they give these delicious foods a taste!

      It should serve about 8-10, depending on the serving size and how many other foods there are.

    Is am so excited to try this.  I am going to a pre-Thanksgiving dinner tonight and I know most of the stuff won’t be primal so it will be awesome to be able to bring my own primal recipe.  I love eating like this.  🙂  Thanks for the post.
