Mashed potatoes are such a tried and true favorite. If you are an onion lover, this is a great way to add extra flavor to the potatoes.
Peel, wash and cut the potatoes into quarters.
Place into a large saucepan and just cover with water.
Bring to a boil, then turn down to simmer and cook about 20 minutes or until the potatoes are tender.
Drain the water. Mash potatoes with milk and keep warm.
While the potatoes are cooking, in a skillet fry onions in butter until golden brown and caramelized.
Do not drain butter that the onions were cooked in.
When onions are done add to potatoes and mix well but don't over beat as potatoes become pasty if you do.
Depending on the consistency you like, may want to add more milk. Season to taste with salt and pepper.
