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 in your fridge! 1/2 tsp equals about one clove of garlic.
- Onion: Make sure that this is finely diced.
- Button mushrooms: These are optional! If you dislike mushrooms, you can just take these out.
- Fresh green beans: Cut off the ends and then cut each green bean in half.
- Chicken broth: I use chicken broth because it gives a slightly added flavor.
- Cream of mushroom soup: I try using a can of low-sodium cream 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 green bean casserole recipe only takes about 25 minutes and tastes amazing! Everyone at our house loves this Thanksgiving side dish, 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 for about 8 minutes until beans are crisp and 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 the mixture to the prepared baking dish and top with french-fried onions. Bake at 350 degrees for 20 minutes, until green bean casserole is heated through.
Green Bean Casserole 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, you can 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 before and keep it covered in the fridge. Be sure to add the fried onions right before baking.

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!

This is a SUPER TASTY & elegant green bean casserole! I’m also a huge mushroom lover, but I always use Crimini mushrooms whenever a recipe calls for button mushrooms. IMO, they have a little more flavor. Also, I never frown upon using a ‘heart healthy’ canned soup in casseroles once in a while, since they have less fat & sodium than the original version. Seriously, they won’t kill you, as some ‘purists’ seem to think. That being said, pay no mind to rude & ascenine remarks as made by Marti Klinger. Her ‘secret recipe’ SHOULD be kept a secret, since I’m sure it contains a whole lot of fat & sodium which her family obviously enjoys, so she’s too embarrased to share it, but just felt like mouthing off & being critical. Your recipe is our new go-to Green Bean Casserole for holidays. Thanks for posting it 🙂
This looks great! How would you recommend preparing this ahead of time? Thank you!
Prepare the casserole ahead of time and leave in the refrigerator over night before baking. If you are baking it then storing it, let cool then place in the refrigerator until ready to serve. Warm back up before serving.
