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!

  1. 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.
  2. 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.
  3. 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.
