Cheesy Mashed Potatoes

Everyone who has tasted these cheesy mashed potatoes asks how to make them. Since this comforting casserole bakes at the same temperature as my chicken bundles, I get it started in the oven and pop in the entree a little later. —Brad Moritz, Limerick, Pennsylvania

Cheesy Mashed Potato Tips

What can I put on top of mashed potatoes?

The mild, buttery flavor of mashed potatoes makes it the perfect canvas for toppings. After baking, sprinkle the top with minced green onions or chives, crumbled cooked bacon and herbs (think thyme, parsley and rosemary).

What is the best tool to mash potatoes?

We recommend using a handheld masher, a potato ricer or a fork to mash potatoes. Resist the temptation to dump the cooked potatoes into a food processor or blender. Overmixing gives spuds a gooey, gluey texture.

What vegetable goes well with mashed potatoes?

Add more color and nutrition to the table by pairing mashed potatoes with colorful vegetables, such as fresh green beans and garlic, roasted carrots with thyme or herbed peas.

    Too dense for me and I added extra liquid (half and half). Tasted good but couldn't get past the heaviness.

    Haven't yet tasted them but made them tonight. Based on smell though that's why they get that rating. Can't wait to taste them.

    So good! I cut the onions chunky and it made it taste so much better than I anticipated.

    These potatoes are creamy and delicious! They reminded me of the filling in a pierogi. I did not add cheese on top.

    First words out of my boyfriend's mouth after inhaling these heavenly taters: "I need this in my mouth, all the time, everyday, for the rest of my life." And I agreed, wholeheartedly. I didn't have any onion so I used a bit of onion powder instead ??, also added 5 strips of cooked bacon before putting it in the oven ??, and then put it under the broiler for a couple minutes after topping it with (extra) cheese at the end ???? Holy bomb. ?????? Killer recipe, thanks for sharing this little bit if heaven. ??????????

    I have been making this dish for family gatherings since it was published in 2002. 15 years later, I still get requests.

    Wow these were really delicious! A little firmer than I like my mashed potatoes though, so next time I might add some cream. But man are they good!
