What is the best way to mash potatoes?

I know many folks who like to use a hand mixer or potato masher. I find it’s easy to overmix with a hand mixer. Using one breaks down the starch in the potatoes making them mushy. On the other extreme, a potato masher can leave chunks of potato making the dish lumpy.

I grew up with my Mom using a potato ricer and it’s what I use to this day. There are one or two exceptions but not many. Years ago I was watching Martha Stewart and she confirmed what I’ve known all my life. A ricer is the best way to make mashed potatoes.

What type of dish do you use for baked mashed potatoes?

For best results, use a large casserole dish. Coat the dish with softened butter then put the mashed potato mixture into the prepared baking dish.

    This is such a good side dish for Christmas and Thanksgiving! I also like that the texture is a lot different from a potato bake. So if you have a highly textured stuffing, this would go really well to provide that ‘smooth’ sensation. Cheers!
