Green bean casserole is a classic, tried, and true side dish that everyone loves! It’s so delicious and creamy that it just might steal the turkey’s spot as the star of the show.
This makes for a great side dish for any delicious holiday dinner! Try this Honey Glazed Ham, this Garlic Butter Herb Prime Rib, or this amazing Oven Baked Herb Turkey.
Green Bean Casserole
Is Thanksgiving even Thanksgiving if there isn’t a green bean casserole on the table? Green bean casserole is a holiday side dish MUST TRY. I have never been a green bean lover, but I can’t seem to get enough of this creamy side dish. This recipe uses fresh mushrooms salted with onions and garlic which takes this green bean casserole to the next level with amazing flavor! One of my favorite parts of this casserole is topping it with those crisp and tasty onions!
It has the best combinations of textures and tastes… It will almost make you think that this is the star of the show instead of the turkey! You can’t go wrong with having this classic green bean casserole at your next holiday meal. This pairs well with both of my turkey recipes! My Oven Baked Herb Turkey or, for a quicker cooking method, this Slow Cooker Turkey Breast. Don’t forget the turkey gravy too! Make this while your turkey is resting. Your holiday meal is going to be the talk of the town!
Ingredients for Green Bean Casserole
This recipe has some fresh ingredients that take this casserole to the next level! See the recipe card below for a list of exact ingredient measurements.
- Butter: I used unsalted butter so that I didn’t add any extra salt in the recipe!
- Garlic cloves: If you don’t have any fresh garlic cloves on hand then you can use the minced garlic that’s in your fridge! ½ tsp equals about 1 clove of garlic.
- Onion: Make sure that this is finely diced.
- Button mushrooms: These are optional! If you don’t like mushrooms then you can just take these out.
- Fresh green beans: Cut off the ends and then cute each green bean in half.
- Chicken broth: I use chicken broth because then it gives a slight added flavor.
- Cream of mushroom soup: I try and use a can of low sodium cream of mushroom soup for this recipe.
- Parmesan cheese: You can finely grate this to add to the recipe!
- Salt: This is used to enhance all of the delicious flavors!
- Black pepper: This won’t give any heat but the perfect amount of flavor.
- Crispy onion strings: These give that perfect added crunch.
Let’s Make a Casserole!
This recipe only takes about 25 minutes and tastes amazing! Everyone at our house loves it and I know that you will too!
- Preheat oven and cook vegetables: Preheat oven to 350 degrees. Melt butter in a large skillet over medium heat. Then, add onions and mushrooms and cook, stirring occasionally, until just tender. Add garlic and cook another 1-2 minutes, then remove from heat and set aside.
- Cook green beans: Place green beans and chicken broth in a medium saucepan and bring to a boil. Cook about 8 minutes until beans are crisp tender and then drain.
- Bake green beans and vegetables together: Spray a 2 quart baking dish with cooking spray. Place the soup, mushroom mixture, green beans, parmesan, salt, and pepper in a large bowl and stir to combine. Then, transfer mixture to the prepared baking dish and top with crispy onion strings. Bake at 350 degrees for 20 minutes, until casserole is heated through.
Frequently Asked Questions
- Can you use canned green beans instead? I would stick to fresh green beans with this recipe! Canned green beans tend to be mushy and tasteless once baked into the casserole, but using fresh beans cooked in chicken broth makes them perfectly crisp-tender and full of flavor! I just grab a few big handfuls of beans, chop off the ends, and cut them in half. You want them in about 1 ½ inch pieces. You will notice the flavor is so much better with fresh green beans!
- Cream of mushroom soup: Even though I use all kinds of fresh and homemade ingredients in this dish, I still stick with the classic cream of mushroom soup to bind all the ingredients together.Yes, I could make a sauce from scratch (and you totally can!) but I love using the canned soup as a shortcut. And quite frankly, I’ll take all the help and shortcuts I can get during the holidays!
- Homemade or store bought onion strings: I like to use store bought onion strings for this because, once again, it makes this so much easier! But if you have time and want to take it to the next level then you can totally make some onion strings on your own!
Can You Make This Ahead of Time?
Yes! You can make this green bean casserole 24-48 hours in advance and keep covered in the fridge. Be sure to add the fried onions right before baking.

This was FANTASTIC! It was a huge hit at Thanksgiving this past year. There weren’t even any leftovers. I will absolutely make this again. Probably before next fall!
How many lbs of green beans should I purchase? Looking forward to making this for Christmas.
This recipe uses 3 cups of green beans. So about 1-1.5 lbs!
Would shocking the green beans after cooking help or hurt when preparing a day ahead? Thank you for sharing, I will be making this today.
Can I use frozen green beans instead of fresh?
I’m wondering about that as well? I don’t see an answer though?
I recommend fresh!
Can you share what kind of onion straws you used here? They look delicious compared to my usual brand! Trying this recipe for Thanksgiving this week. Thanks!
Hi! I used my homemade onion strings! Here is the recipe! Crispy Onion Strings
i had two questions, both of which I’m going to try this weekend on a test run but I was curious if anyone else had tried/knew the answer:
1) instead of the 350 degrees for 20 mins, would it be possible to do 300 for 30 minutes? I’m using my grandmother’s sweet potato casserole and it needs 300 temp…..maybe it will be fine to buddy them up?
2) can I prep ahead of time? aka: night before: cook green beans, set to room temp and mix ingredients minus topping, and place in fridge over night – pull out thanksgiving day and set to room temp, then get ready to bake?
any ideas would be much appreciated!! I usually do French’s recipe but this sounds soooooo very much more flavorful!
I haven’t tried cooking it at a different temperature but I think that should work! You can go ahead and assemble this and cook it later, just like you stated! Let me know how it turns out, it’s a family favorite!!
Is the condensed mushroom soup cans OK to use? Mix with an equal part of water?
Yes! Just use it straight from the can.
Thanks but the recipe suggests to drain out the chicken broth, should that then go into the final baking mix?
The can of mushroom soup will go in during step 3!
I too would like to know about draining the broth from the beans. Is it that the beans will absorb enough broth after draining to not need water added to the soup? Or are we mixing the drained broth into the soup as we pile everything into the casserole dish to thin it out a bit? Im assuming just drain and discard the broth but if there is extra flavor to be had i wouldn’t wanna skip out on it.
You will just drain the beans (the chicken broth is used to cook them and add flavor) and then in step 3 you will add in a can of mushroom soup. No need to add additional liquid.
I have done so many recipes this is by far my favorite. I used homemade chicken bone broth so maybe added a little extra flavor. Kids were eating it so I snapped green beans into 3 and boiled a little extra to make sure they were soft. Whole Foods brand fried onions were great. Going to make again thank you so much!
Can you leave the mushrooms out of this recipe don’t like mushrooms.
Sure! Adjust it however you like!
