Mashed Potato Green Bean Casserole is a delicious combination of two of my favorite Thanksgiving sides. On the bottom, a creamy layer of mashed potatoes covered by a cheesy green bean casserole.
Each one tastes incredible on its own, but even better when combined into one extraordinary side.
Best thing about the recipe?
It’s a total breeze to prepare thanks to Simply Potatoes Traditional Mashed Potatoes®.
Simply Potatoes Traditional Mashed Potatoes are made from real ingredients, fresh never frozen potatoes. You can find them in the refrigerated section of your store or learn more about them here.
No time wasted peeling potatoes. These potatoes are ready to be heated and eaten. So much prep time is saved and they are my go-to secret weapon to easily prepare a meal the whole family will enjoy.
I think you’re really going to love the way a layer of Green Bean Casserole (with cheddar cheese no less!) tastes on top of these mashed potatoes. I use fresh green beans, but you can use canned, plus a can of cream of mushroom soup, a little milk and soy sauce, and lots of French fried onions.
Trust me when I say if you’re a fan of green beans casserole and you like mashed potatoes (who doesn’t?) you are going to love this Mashed Potato Green Bean Casserole!
Type Of Green Beans To Use
I use fresh, cooked green beans that I have boiled until tender. You can use canned green beans if you prefer or frozen green beans that have been cooked according to package directions.
Add A Little Spice
To make this recipe spicy, add a pinch or two of cayenne pepper.
Make Ahead and Storage
Can be assembled ahead of time but wait to add the onion topping just before baking. Leftovers will keep in an airtight container in the refrigerator for 3 days. Reheat in a 350 degree oven to crisp the topping back up.

We always add parmesan cheese and we sometimes will add grilled onions.
I like flavoring them with garlic, butter and fresh herbs!
These potatoes have some real razzle dazzle! I could pretty much just have mashed potatoes for supper, and you’re getting me one step closer to actually being able to call them a meal and get away with it. Because people make meals out of sides, right? I wouldn’t just be eating potatoes anymore. ?
Butter and roasted garlic…..
A little cream, a fair amount of butter and a sprinkle of salt and I’m set! Especially if there’s fresh turkey gravy to ladle over them.
This looks so delicious and easy! Will have to try. Thanks for the giveaway too!
Thanks for the giveaway and great recipe. Unfortunately, I do know a kid who doesn’t like mashed potatoes and for the life of me, I can’t figure out why. I’ve tried them every kid friendly way you can imagine. Anyway, I like to add roasted garlic to my mashed potatoes. Since the munchkin won’t eat them, I only make them for the grown ups and we like lots of garlic, lol.
COPIOUS butter and rosemary. we like a little seasoned salt too. 🙂
My favorite way to flavor up my mashed potatoes is with roasted garlic.
I like to add blue cheese to mashed potatoes, so decadent!
