Peel and dice the potatoes into even-sized chunks. Place them in a large pot of salted water and bring to a boil over high heat.
Reduce heat to medium and cook the potatoes until they are fork-tender, about 15-20 minutes. Drain the potatoes and transfer them to a large mixing bowl.
While the potatoes are cooking, melt 2 tablespoons of butter in a skillet over medium heat. Add the finely diced onion and sauté until golden brown and caramelized, about 8-10 minutes. Set aside.
Using a potato masher or handheld mixer, mash the hot potatoes until smooth and free of lumps.
Add the shredded cheddar cheese, caramelized onions, 1 tablespoon of butter, salt, black pepper, and sour cream (if using) to the mashed potatoes. Mix thoroughly until the filling is smooth and evenly combined.
Taste the mixture and adjust seasonings as needed. You can add extra salt, pepper, or cheese to suit your preferences.
Let the filling cool completely before using to stuff pierogi dough. The filling can also be made ahead of time and stored in the refrigerator in an airtight container for up to 3 days.
