Tater Green Bean Casserole is a simple twist on the classic casserole. Green beans, O'Brien potatoes, cream soup, cheese, and seasoning!
TATER GREEN BEAN CASSEROLE
During the holidays, I am a side dish fanatic. Yeah, the turkey and ham is nice and all but what I look forward to the most is the side dishes. I love a good ole green bean casserole. So, I thought, how can I 'beef' it up a little without changing it too much. Y'all, I tossed in some finely diced potatoes and it turned out amazing!

FREQUENTLY ASKED QUESTIONS:
O'Brien Potatoes are frozen finely diced potatoes, onions, green and red peppers. They are found in the frozen food section of your grocery store near the hash brown potatoes.
You could substitute with shredded frozen hash browns. For this recipe, if you want to use fresh potatoes you would need to finely dice them then par-boil them so they would cook evenly with the other ingredients.
I will tell you that my entire family detest mushrooms. None of us like them and I can tell you that absolutely no one tastes mushrooms in this dish. However, you could substitute with cream of chicken or cream of potato. If you like the flavor of celery then you could even use cream of celery.
To turn this side dish into a main dish, add some protein! Add one pound of cooked and crumbled ground beef, chicken or turkey to step one of this recipe.
Yes. You can prepare this casserole as written (just don't bake it). Cover well with plastic wrap then aluminum foil to prevent freezer burn. It will last up to 3 months in the freezer. When ready to prepare, allow the casserole to defrost overnight in the refrigerator then proceed with the cooking directions below. Just don't forget to remove the plastic wrap before cooking.
Leftovers should be stored (covered) in the refrigerator for no more than 3 days.

I made this last night and it was a big hit. Since there is only two of us, I halved the recipe, added ground beef, baked it in an 11 x 7 dish and still have enough leftover for another meal. Next time I am going to switch it up and use chicken, broccoli and cream of chicken soup. Yum!!
Gayle S.
Have you tried it with one of the meats? Just wondered if it worked ok. Thanks
Brandie @ The Country Cook
Hi Gayle, I haven't but a friend of mine did it with cooked and crumbled ground beef and assured me it was a huge hit as a dinner for her family! 🙂
Heather Maves
What kind of shredded cheese do you use?
Brandie @ The Country Cook
I prefer a Colby or Monterey Jack cheese 🙂
Deb Van Driel
I saw this recipe & thought "hmmmm". My daughter's does Thanksgiving & some of us love the GBC but my son-in-law is more of a corn fan. Do you have any simple corn recipes that are rather simple that don't include onions or any big bold flavors?
Linnie
Never was a big fan of Green Bean Casserole, but I tried this for Christmas dinner and we all loved it. Really good.
Pam Adelman
Can you make head the casserole and freeze it .
Sophie
I LOVE this recipe and have been making it for holidays for a couple of years now! It's always a huge hit... so thank you for that! I have another Thanksgiving event this year that I planned to make this for, but this particular group only eats organic. I was hoping to swap out the veggies this year with fresh green beans and potatoes. Any recommendation on cook time?
Annetta
I like the idea of this recipe. Am going to try it. Also like the idea of making it into a meal by adding ground beef. I was thinking of using diced chicken or left over turkey. I like recipes like this one that you can play with.
Amanda
I made this for Thanksgiving last year and it was a big hit! Even the people that usually avoid green bean casserole tried it and loved it 🙂 I'll be making it again this year.

I'm planning to make this for a pre Thanksgiving lunch at our church tomorrow. Just wondering if it would be ok to partially thaw the taters.before cooking. Don't want the taters to over cook but want to make sure they're well done. Thanks so much and I hope you and your family have a blessed Thanksgiving!

Not a huge fan of green bean casserole, but this looks great! Gonna give it a try for sure.
Riki Connolly
Hey Judy,
My daughter never has liked green beans, so one year I changed it up and use broccoli florets instead. It's great. Make it every year since. Sometimes I add chicken or turkey from thanksgiving or ham.
Brandie @ The Country Cook
Riki - that is so creative!
Lynn Tucker
I saved a recipe from Campbell's soup a long time ago and it basically swapped out cream of mushroom soup for cream of broccoli and green beans for broccoli, and I agree, it was a great change!
Brandie @ The Country Cook
Hi Lynn - yes! I just tried a casserole that switched out green beans with a mix of broccoli and cauliflower and it was indeed delicious!!
Toni Wilson
Did you also sprinkle on some parsley with the cheese? Looks yummy. I'm going to try this!
Brandie @ The Country Cook
Yes! Just some dried parsley flakes to make it look pretty 🙂 Totally not necessary for taste though!
Carlee
What a great twist on a family favorite! We are going to have to give this a try!
Brandie @ The Country Cook
Thanks Carlee! Super easy and it combines two side dishes into one basically. Ha!
