In a large pot, add potatoes and fill with cold water until it just covers the top of the potatoes. I use a large stockpot for this so I can blend right in the pot, but you can use a smaller pot and transfer the cooked potatoes to a large bowl if that’s what you have. More on that later.
Over medium-high heat, bring the covered pot to a boil, uncover, and then reduce the temperature to medium-low. Cook for about 20 minutes, until they are quite soft and the potatoes easily take a fork sliding into them.
While the potatoes are cooking, add cottage cheese, garlic powder, 2 teaspoons of salt, ½ teaspoon of pepper, and the chicken stock to a large blender. Blend for about 2 minutes until smooth, scraping the sides of the blender as needed.
Drain the potatoes and add them back to the pot.
Add in the butter and half and half and use a handheld mixer or potato masher to mash them until very smooth.
Add the blended cottage cheese to the potatoes and mix it in by hand so the seasoning is well distributed.
Taste and add more salt if needed, I usually add another ½ to 1 teaspoon of salt.
Transfer to a platter or individual plates, top with chives.
I like to serve with any red meat, chicken, lamb, or pork dish you desire. Enjoy!
