This Skinny Gluten Free Green Bean Casserole from scratch has the most amazing taste you can expect from a classic green bean casserole. Made with fresh green beans and mushrooms. Topped with fried onions and parmesan. No canned mushroom soup or heavy cream. Plus, onions are fried in very little oil.
I don't even remember how many times we've made this gluten free green bean casserole since I first tested the recipe. Creamy yet healthy. Whoever eats it LOVES the recipe and wants to make it for their family. This casserole is a perfect match for your Thanksgiving menu. Seeing that this casserole is a favorite one among our readers too, we decided to update this post with new photos and with a few changes in the recipe.

I used eggs in the original recipe, but after receiving several suggestions from you, I tried it without eggs and added mushrooms instead. It becomes even tastier this way! Also, I added onion rings as a final topping in this version. We love this updated version better.
This healthy Green Bean Casserole has already become one of our favorite vegetarian dishes. Green beans are my favorite summer vegetable and I mostly make Turkish Braised Green Beans , which is another great vegetarian dish. I also love to experiment new recipes with it like Fried Green Beans because I want to use fresh green beans as much as I can. You know frozen or canned green beans are not even close to the flavor of fresh one.
Ingredients
Besides fresh green beans, we need two more vegetables: Onions and mushrooms. Also, it calls for milk and parmesan, but you can use another cheese that melts well when baking. Also, to make this green bean casserole gluten free, we use cornmeal. As for the oil, olive oil is our choice for this amazing side dish but other type of oil would work fine too. Oh and don't forget salt and pepper!
The idea of this green bean casserole was born when we were enjoying our Skinny Zucchini Casserole. Glad it did! This is a super yummy green bean dish and I can’t believe how I didn’t try it before. I haven’t yet met a single person who hates green beans, but if there is someone you know, please share this recipe. It will be their turning point in the kitchen.
Dairy Products In This Casserole
This is not a dairy free gluten free green bean casserole. For one thing, it is topped with a reasonable amount of cheese. You can definitely increase or decrease the amount for your taste. Besides, unlike most recipes that call for heavy cream, I use unsweetened fat-free milk to give it a milky flavor. If you like heavy cream and don’t care about skinny recipes, use it instead.
How to Make
I use the same pan to cook everything for this casserole. First, I boil the beans and drain. I dry the pan and cook onions and mushroom in the same pan. Then I transfer the cooked beans into this pan and stir well to combine everything well.
The important thing when making this gluten free green bean casserole is to boil the green beans in the right way. So what does that mean? Put green beans in boiling salted water and cook them just for 3 minutes and transfer them immediately into a large bowl full of water and ice cubes to stop its cooking. They will keep their lovely green color this way and your casserole will look even more appealing.
I didn't use store-bought mushroom soup in this recipe. To make it skinny, healthy and tasty, I made my gluten free green bean casserole without mushroom soup. This method is way easier: Cook mushrooms and in a pan, combine them with milk and cornmeal in the same pot. Fold in the blanched green beans and bake them together in a baking pan.
Meanwhile you can prepare the onions for topping, again using cornmeal. Coat onions with cornmeal and cook in heated olive oil until brown. Top the baked green bean casserole with these onions and serve immediately.
Which Green Beans?
Fresh green beans are the best option for this recipe, but use frozen green beans if you can't find fresh. Just thaw them before using in your casserole. No need for additional cooking, so they make the recipe even easier and quicker.

Hi, just wondering if you have the old recipe also. I like both of them, but liked that the previous recipe was more loaf-like too.
Zerrin says
Hi Erin! Sorry for removing the previous recipe. There might be slight differences about the amounts but it was very similar to our Skinny Zucchini Casserole. I remember deciding to replace zucchini with green beans. That's how the previous recipe came out. Hope this helps.
Jenny says
I just pulled this dish out of the oven about 20 minutes ago! I doubled the recipe and added mushroom and extra cheese to my casserole. I'll be heading to Thanksgiving dinner in a couple of hours and I'm excited to cut into this casserole! Thanks for the recipe:)
Martha says
I know it's been almost a year, but since it's nearly that time again, I was wondering how your family/friends enjoyed the casserole.
Are you making it again this year? Would you mind giving us an update, please? I'd love to know what others think of this after they've tried it.
Was it good enough for seconds? 😁
Zerrin says
Hi Martha! I've updated the recipe myself 🙂 After receiving so many emails from readers about the changes when they made the recipe, I decided to update it with the guidance of our readers' suggestions. So the original recipe required eggs in the sauce, but this updated version doesn't. Also, lots of people recommended me to use mushrooms. As far as I know, canned mushroom soup is used in the classic green bean casserole. I prefer to make a sauce myself using mushroom, milk and cornmeal. Super creamy and yummy! Also I top it with onion rings that are fried in little oil after it is baked. As a result, I think the mushroom and onion additions make the recipe even more scrumptious.
I'd love to thank you all for the ideas to improve this recipe!

How many calories would you say are in this dish? I tried adding them up and if there are 4 servings per dish, I got the calorie count to be about 301 calories per serving. To me, that's not a skinny dish, especially if it's just a side instead of a main course. Just wondering if you used healthier ingredients to get a better calorie count? It does look tasty but I'm looking for a little less calories in my thanksgiving sides.

Hiya Zerrin! I had totally lost track of your blog until today when I ran across it again. I'm glad I did - this recipe looks really good, and we are just starting to have a lot of beans in the garden. Yum!
Zerrin says
Hi Donalyn! Great to see you back! This is one of our summer hits. How lucky you are to have fresh beans right from your garden.
