GREEN BEAN CASSEROLE RECIPE
I know I’m not exactly blowing anyone away with my creativity here.ย There are literally hundreds of green bean casserole recipes out there.
BUT, this is the way I always make mine, and it’s ALWAYS a hit for Thanksgiving and other holiday dinners.ย So I knew I had to share it with you all!
If you’ve never had a classic green bean casserole before, it’s green beans mixed with a creamy, seasoned mushroom sauce, baked, and topped with crispy fried onions.ย Simply put, it’s simple, but ohhhhhh so amazing and delicious.
HOW TO MAKE GREEN BEAN CASSEROLE
There’s really nothing to this ultra-easy side dish, and you’ll love the only 5 minutes of prep time!
- Pat green beans dry.
- Mix together soup, dairy and seasonings.
- Stir in green beans and some of the onions.
- Transfer to baking dish, bake until bubbly.
- Top with more onions and bake another few minutes.
COOKING TIPS FOR THIS GREEN BEAN CASSEROLE RECIPE
- Green Beans – I’ll go over the types of green beans you can use in the next section, but here I want to talk about drying your green beans.ย If you don’t pat them dry, the sauce will sort of slide right off the beans, instead of coating them.ย Trust me, it only takes a second, and it’s worth it!
- When in doubt, make moreย – this casserole is always a crowd pleaser, so if you’re on the fence about if you’ll have enough, I would make more!ย For our Thanksgiving, I end up quadrupling this recipe.ย Helpful hint: in the recipe card below, if you hover over the servings number, a toggle bar will show up.ย Slide the bar to adjust for how many servings you’ll need, and it will automatically calculate the ingredient amounts you’ll need!
VARIATIONS OF GREEN BEAN CASSEROLE
- Cheesy – add in 2/3 cup of shredded cheddar to the casserole mixture and top with another 1/3 cup of cheddar before baking.ย We love this version, and find sharp cheddar tastes amazing!
- Bacon – adding some crumbled bacon to the casserole and/or topping adds crunch and great savory flavor.
- Mushrooms – add a small can of sliced mushrooms to the casserole, or saute some sliced fresh mushrooms and add those.
- Onions (fresh) – sauteing some diced onions and adding them to the casserole mixture adds great flavor!
- Fried Onions – French’s brand are the traditional onions used, but there are bags in my grocery’s produce department (the brand is Fresh Gourmet) that have various flavors that are fabulous to use as well!ย Garlic Pepper is our favorite.
USING FRESH GREEN BEANS
I love the taste of fresh green beans, and they’re surprisingly easy to use in this recipe.
Trim the ends and cut green beans in half across.ย Place in a microwave-safe bowl and microwave for 5-6 minutes to soften.ย Pay dry and use as directed.
USING FROZEN GREEN BEANS
This is the option listed in the recipe, as it’s what I normally use to make this recipe.
Thaw or microwave for a few minutes to defrost.ย Pat dry and use as directed.
USING CANNED GREEN BEANS
Canned green beans are traditionally used in a green bean casserole, and will result in a softer texture than the fresh or frozen variety.
Drain and rinse the green beans, then pat dry and use as directed.
MAKING THIS CASSEROLE AHEAD OF TIME
If you’re making this recipe for Thanksgiving, you know that the most difficult part about good ol’ Turkey Day is finding time to make all the dishes and how to bake them so they’ll be ready at the same time!
Thankfully, green bean casserole is perfect for making ahead of time.
ASSEMBLE AHEAD OF TIME (UNCOOKED)
This is the method I use for my own holiday dinner plans, and it works perfectly.
- Assemble casserole, making sure to leave off the onion topping.ย Cover dish tightly with foil and refrigerate up to 3 days.
- Remove casserole from refrigerator for about 30 minutes.ย I usually let mine rest on the counter.
- Bake casserole as directed.ย If your dish is really cold, add another 5-10 minutes of bake time.
BAKED AHEAD OF TIME
Alternatively, you could bake the casserole ahead of time, and just reheat it when you’re ready to serve.ย This method results in a softer texture to the dish, as it’s basically baked twice.
- Assemble and bake casserole, omitting the onion topping part of the baking process.
- Let dish cool to room temperature, then cover tightly with foil.ย ย Refrigerate for up to 3 days.
- Remove casserole from refrigerator for about 30 minutes.ย I usually let mine rest on the counter.
- Bake at 350 until hot and bubbly, about 20 minutes.ย Add onion topping and bake another 5 minutes.
FROZEN
Of the make ahead options, this is my least favorite, since dairy can be tricky to freeze successfully, but if you need to make your green bean casserole more than a few days before, it’s an option.
- Use either the assembled or the baked make ahead option from above, but instead of refrigerating, freeze for up to 2 months.
- Thaw overnight in the refrigerator.ย ย Remove casserole from refrigerator for about 30 minutes.ย I usually let mine rest on the counter.
- Bake casserole as directed.ย If your dish is really cold, add another 5-10 minutes of bake time.
STORING
Leftovers (if you have any!), should be transferred to an airtight container and refrigerated for up to 3-4 days.
SLOW COOKER GREEN BEAN CASSEROLE
No oven space? No worries!ย This recipe can be adapted for a slow cooker.ย It won’t have quite the same texture, but will still taste amazing.
To make this recipe fit in a standard crockpot, double the recipe (double all ingredients), and mix everything in the crockpot, cover and cook on LOW for around 6 hours.ย I like to NOT add any onions to the casserole mixture for this version, as they get reallllly mushy.ย Just add all the onions to the top once it’s done cooking and give it a good stir.

Tripling the recipe. Baking time? Also, I’ll be using warming trays for all of my food. On TG day, how far ahead of time should I bake this if we anticipate dinner at 2? (I will assemble ahead of time uncooked). You probably can tell I’m pretty new at this! Do I put food on warming trays at room temp, or do I put them hot out of the oven? THANK YOU!
The Chunky Chef says
You’ll likely want to bake this for about 40-45 minutes, so I would bake it around 1. And put the food on the warming trays after it’s baked, so it’ll stay nice and hot ๐
Laura says
I made this last year for (Canadian) Thanksgiving and I am by no means a โcookโ they were so easy to make and turned out great, family loved them! I used frozen French style green beans and added dried onion flakes instead of fresh. When shopping I couldnโt get French onions so decided to try breadcrumbs but regular ones were out of stock so on a whim I tried panko which I had never heard of tbh! I added grated Parmesan cheese to them and it was great! Making again today for Thanksgiving tomorrow for my whole family this time. ๐ Thanks for a great recipe that I will use for years to come!
Bq says
Followed your recipe as an outline for Thanksgiving. Husband loves green bean casserole. I used fresh greens beans and followed the recipe without the soy sauce. Not ready to try something new haha. Turned out great! Thank you!
Astrid says
Can I use fresh beans instead of frozen? Do I need to pre-cook them? I don’t want them to be too mushy when the casserole is done.
Astrid says
nevermind, I scrolled to the top and found my answer. Thank you
Robbin says
Hi Amanda and Happy Thanksgiving! If I double this recipe do I need to cook it longer? I have a have a large rectangular casserole that will not increase the depth of the casserole. Thanks in advance!
The Chunky Chef says
Hi Robbin ๐ That shouldn’t increase the baking time by too much, I would add about 10 minutes to the baking time and check to make sure it’s hot throughout. Happy Thanksgiving to you as well!
Jan says
Hi! My family loves this dish! Thank you for the tips! My question is, can I use the microwave to cook the assembled dish first. Then put it in the oven with the onion topping for 5 minutes?
The Chunky Chef says
I haven’t tested cooking this recipe in the microwave, so I can’t say for certain whether it would work or how long it would take. If you do some experimenting, I’d love to know how it turns out ๐
Michelle C says
Canโt wait to make this for Thanksgiving! Iโm using a few of your recipes and know they will all be great ๐ can I use fresh green beans or you recommend thawed frozen green beans? On the bag of the frozen ones it says do not thaw before cooking so I want to confirm with you. Thanks!
The Chunky Chef says
I prefer the ease, and taste of using thawed frozen green beans, but you can use fresh. Please see the section of the post above the recipe titled “using fresh green beans” for all the details. I hope you have a wonderful Thanksgiving!
Gee says
For some reason I cannot get the serving size to increase to 18. Would just tripling the ingredients work?
The Chunky Chef says
Yes, tripling all the ingredients is what you’d need for the 18 servings ๐
Carol says
I personally love Green Bean Casserole and this version did not disappoint! I learned a thing or two: pat the beans dry was one. Also, I did the Assemble Ahead of Time (uncooked) method. I used canned, french-cut green beans. The members of my family that love GBC loved it, and those that turn their nose up at GBC just ignored it, as always! I’ll be using your method again, thanks!
Kyndra Caldwell says
So glad I came across this! I need to make it ahead of time. Do I still add the French fried onions in the mixture, and just leave off the top? Or do I leave the onions out all together til Iโm ready to bake?
The Chunky Chef says
I’ll be making this ahead of time for Thanksgiving as well ๐ I add the onions that are in the green bean mixture, but leave off the ones on top until I’m ready to bake.
Sandra says
This will be a great addition to our Thanksgiving table!
Jacque Hastert says
Nothing beats a classic like this! This is always a staple on our Thanksgiving table.

This is my husbands favorite side dish for the holidays! Love the added flavor of soy sauce! So good!
Kimberly says
Classic for a good reason, it’s hard to imagine Thanksgiving without it, yum!
