Peel and cut the potatoes into smaller pieces. I cut them into two or four pieces based on the potato size.
In a large pot, add potatoes and fill with cold water until it reaches the potatoes' top. Bring to boil and then reduce the temperature slightly.
While the potatoes are cooking, add cottage cheese, salt, pepper, and 2 tablespoon half-and-half to a blender and blend until smooth.
Cook the potatoes until they are fork-tender. Usually, it takes about 20-25 min after it boils. Drain the potatoes using the mash strainer to remove the excess water, then add them back to the pot.
Add butter and 2 tablespoon of half-and-half to the pot. Use a potato masher to mash the potatoes until well combined and the potatoes are creamy. Add the blended cottage cheese to the pot. Taste and add more seasoning if preferred. Serve warm!
