Clean the potatoes thoroughly and then cut them into cubes. Place the cut potatoes into a large stock pot and cover them with water.
Bring them to a low boil on the stove over medium high heat. Allow them to boil for about 10-15 minutes, or until they are fork tender.
Drain the water out of the potatoes and add them back to the pot. Now add in your boursin cheese, butter, and heavy cream. Start by adding just ½ cup of heavy cream, and add more to get your desired consistency.
Use a potato masher to mash the potatoes while simultaneously blending in the cheese, butter, and cream.
Once the potatoes are a smooth-like consistency, sprinkle in the seasoned salt, garlic powder, black pepper, and garlic and herb seasoning.
Use a spoon to mix the seasonings into the mashed red potatoes until it is fully combined.
Serve right away, and enjoy!
