Fill a large pot with 3 quarts (12 cups) of water or broth and bring it to a boil over medium-high heat. Add the smoked ham hock, then cover and cook for 45 minutes to 1 hour until the meat is tender.
1 to 1 1/2 pounds smoked ham hock, 12 cups water or chicken broth
Meanwhile, thoroughly rinse the collard greens to remove any dirt or grit. Strip the leaves from the tougher stems that run down the center of each leaf. Stack 5-6 leaves on top of each other and slice into 1/2" to 1" pieces.
3 pounds collard greens
Add the greens to the pot with the meat, along with the onion, sugar, butter, vinegar, seasoned salt, red pepper flakes, garlic powder, and black pepper. There should be enough liquid to just cover the greens.
1/2 large onion, 1 Tablespoon granulated sugar, 1 Tablespoon salted butter, 1/4 cup apple cider vinegar, 2 teaspoons seasoned salt, 1/2 teaspoon crushed red pepper flakes, 1/4 teaspoon garlic powder, 1/4 teaspoon black pepper
Bring back to a boil, then cover and cook for another 60-90 minutes, stirring occasionally, until greens are tender.
Remove the meat from the bones, finely chop, then return the meat to the pan, discarding the bones. Taste and adjust the seasoning as needed (add a few dashes of hot sauce if you want more spice to your greens).
