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.

I like to add cheddar cheese to mashed potatoes.
I’m a fan of traditional mashed potatoes, but gravy and LOTS of black pepper are a must!
I like to add white cheddar cheese, garlic and siracha
I use sour cream and lots of butter!
I like to make loaded mashed potatoes sort of like loaded baked potatoes. I add: cheese, milk/cream, sour cream, chives, butter, and bacon.
Gravy for the win! But if I can’t have gravy, dill and butter are pretty great 🙂
Definitely gravy for my mashed potatoes!
Garlic, butter and salt, or if it’s Thanksgiving, gravy!
This must seem weird but I loooove some Brie melting on my mashed potatoes!!
There’s nothing like homemade gravy for mashed potatoes
