  1. Hey Kate! Your recipe works perfectly — before this I’ve been disappointed with Ippy mashed potato recipes! If you want to make mashed potatoes with the Ippy and then freeze them, you can sub the butter and milk with 8 ounces cream cheese and an egg. Mash in the cream cheese first, and then the egg (the potatoes are still hot enough to avoid the risk of raw egg). Put them into freezer-to-oven safe casserole dish (full recipe fits into a 3 quart or 9×13), cover, and freeze. To reheat, thaw completely and then bake for 35-40 minutes at 375°F, until top is golden. They don’t have to be frozen, either, they can be made a day or two ahead, refrigerated, and then reheated as if from defrosted. Combining your Ippy method for the potatoes (including seasoning salt) with the make ahead method leaves the Ippy available if you want to use it to make a good beef stew or need it for other dishes.
