Made this and love it.

Can I use the already made mashed potatoes from the grocery store?

Hi there! You can use packaged potatoes, so long as it doesn't have any sour cream in it. They need to be plain. Enjoy!

All righty!!! Thanks!

Have been making an almost identical recipe for about 45 years now ,and will try this one with the cream cheese. You just cannot go wrong with this! Even my son-in-law, who doesn't care for mashed potatoes, asks for these for every dinner.

Fantastic Side dish !! I did make one change.I used caramelized onions on the top in place of the fried onions. SOOO GOOOD!

I like the idea of the caramelized onions! My fiance does not like french fried onions so this is a great alternative!

Tried this recipe? What did you think?

Can I mix ingred. and store in refrige until I'm ready to bake it?

Hi there! Yes, the Test Kitchen believes that it's okay to prepare this recipe beforehand and store it in the refrigerator until you're ready to bake it. Enjoy!

If mashed potatoes were my thing, this might be on the menu soon. How would it be with sweet potatoes?

Hi there! The Test Kitchen does not believe that this recipe would have the same outcome if sweet potatoes were used. We recommend one of our sweet potato casserole recipes instead. :D You can find them by searching for "sweet potato casserole" in the top right corner of our homepage. Enjoy!

This looks so good!

Looks and sounds like a wonderfully delicious recipe! Pretty easy to make too! Thank you for sharing )

This recipe sounds delicious especially with the potatoes and cream cheese.

A nice comforting winter dish!

This is making me hungry, I'm sure it's a delicious casserole.

This looks wonderful and very rich (a good thing).

OMG this sounds delish! Def gonna bookmark it for future ref!

I'm excited to say I'm going to use this recipe for my pierogi's that I'm making for Christmas. I'm so fussy with potato pierogi's the basic potato and cheese just don't do it for me. I might share some o) lol

this was o.k. Almost over filled my 3 qt. dish. Makes a LOT

delicious...I too cut recipe down as only two of us...and I put peeled garlic cloves in with the potatoes while they were boiled...then it becomes cheesy and garlicy mashed potato casserole...yummy

This was a big hit!! Since I only cook for 2, I cut the recipe in half and still had leftovers ) Easy peasy!! Thank you

Glad you mentioned cutting the recipe in half. There are only two of us here too, and we are not big eaters. Thank you.

Next on my list---looks great to me

Personally, I wouldn't add the canned onion rings until the last 5 mins. of baking so the rings are just golden and not burned.

To cook potatoes, especially they are going to be mashed, I cook them in the microwave. Peel, cut up, cover with water, and a sheet of plastic wrap over the top. Time depends on how many potatoes there are. I usually use approximately 4 to 5 and zap them for about 14 minutes. Drain and then mash in the same bowl you cooked them. Of course make sure it's microwavable. I have a 2 qt. glass mixing bowl shaped like a pitcher with a handle and spout. It works perfect for the potatoes and lots of other things.

Also very good with cauliflower instead of potatoes

mmm tasted great with the brisket

can you use shredded cheddar cheese instead of cream cheese?

You can always make changes to a recipe with ingredients you prefer. It might not taste the same as the originial but then isn't that the purpose of the substitutions, to make it taste different?

sound real tasty..will try soon and let you know..thanks

Great...finally something new to do with mashed potatoes...can't wait to try and also share with my daughter and her family. They all love mashed potatoes.

I would think 5 lbs of potatoes would make more than 6 servings, does anybody know?

I think you're right. Normally, for mashed potatotes, you use one potato per person and then throw one extra in for good measure. This sounds like a casserole dish for company or potluck--serving more than six (unless they're teenagers and then who knows). This also would be good with the use of softened chive cream cheese, I think. Bon Appetit!

I halved the recipe when I made it for my 2 children and I and there was enough left over for 3 more serves. Delicious though.

As the years go on, the grands get bigger, as do their appetites. With 9 adults, I cook 4 1/4-4 1/2 lbs of potatoes for mashing, and it feeds everybody, with 2 usually having seconds. The 9 adults are 3 women and 6 men. Hope this helps

Sounds good-I think the addition of garlic and bacon bits would add a lot of extra flavor.
