Bring a large pot of water to a boil, add the chopped potatoes, and simmer for about 10-15 minutes until the potatoes are very tender. (The tip of a sharp knife should slide in easily.)
Drain the potatoes and set them aside.
In the same pot, melt 2 Tbsp of butter, and sautee the chopped kale over low-medium heat for 5-10 minutes until soft.
Take off the heat, add the potatoes back to the pot along with the rest of the butter, half-and-half, salt, and horseradish sauce. Mash together with a potato masher until all the ingredients are fully incorporated.
Adjust seasonings to taste, and serve with more butter if desired.
