REPIN this Easy and Delicious Casserole
You didn’t say but if I’m using russets am I supposed to peel them or mash with skins on?
Great question, if using Russets, you’ll want to peel them first. I have updated the recipe to include this information.
how do you prepare if you want to make them one night before ?
I would suggest to prepare as directed reserving the cheese for on top in a separate container. Cover and refrigerate overnight. Remove from the fridge 30 minutes before baking and cover with foil. Bake at 375°F for 30 minutes. Stir, top with cheese and bake uncovered for an additional 15 minutes or until heated through.
Best loaded mashed potatoes. We made it at Christmas and we’re making it tonight. My son (who is 14- and picky) has been begging for this dish! Thanks for all the tasty recipes and great cooking techniques!
That makes me so happy to hear! I am glad he is enjoying it.
Absolutely delicious!!!
how much to use in a 8x8pan for 2 people.
Hi Maryann! If you scroll down to the recipe card and hit ‘print’ you will be able to adjust servings to 2. I hope that helps!
Why not microwave potatoes first?
You certainly can microwave them.
Can you use instant potatoes if so how many cups of potatoes?
Yes, instant potatoes will work just fine, you will need about 6 cups of mashed potatoes for this recipe.
What is the baking dish size and baking time if you double the recipe? That doesn’t seem to change on the website when I select 2x
Looking forward to making this for Xmas eve!
A double recipe will fit in a 9×13 pan, you will need to increase the cooking time slightly as well Cristina!
Have you ever frozen it – I am not sure about that since it has dairy products in it. I have had issues with freezing anything with dairy. It becomes clumpy and weird. This recipe is so great -we are having it with a ham steak for breakfast. Mmmmm!!!
Absolutely, I make them ahead of time and freeze, you can bake right from frozen. I do approximately 350°F for about 45-55 minutes.
I made this for a pot luck and I will definitely be making it again!
Can u freeze this?
Definitely, Hannah! You can freeze this, then let thaw in the fridge overnight and bake according to the recipe instructions.
turned out awesome. used red potatoes and boiled them. So easy!
5 stars
Would packaged bacon bits work instead of cooked/crumbled bacon?
That should work just fine Trudy!
Tried it last night and we loved it.
Love the recipe, but I just kind of stir and chop the potatoes with a spoon so they are more like eating a baked potato than mashed.
This recipe is OMG sinful! It will be a go-to for special occasions.
I’ve got mine in the oven now! I make it every couple of months – so yummy! Serving along side buffalo chicken wings and a salad.
I also would like to make it in our crockpot. Do the potatoes need to be cooked first?
Yes, the recipe should be prepared up to step 3. and spread into a slow cooker instead of a casserole dish. You may need to double the recipe depending on the size of your slow cooker.
Holly you were right! Thanks! I didn’t have oven space today for our family holiday so I made this in my 9×13 crockpot and it was amazing as usual. 3 hours on low.
So glad it worked out for you Wendy!
