Fill a large pot with water and boil your potatoes for 20 minutes, or until soft. You want them to crack/break apart when poked with a fork.

Remove potatoes from the heat and drain all but ~½ cup of water in the pot.

Next, add 2.5 cups milk, onion soup mix, and cream of celery to the pot.

Mash the potatoes with a potato masher until desired consistency is reached.

Optional step: pour 3 cups of soup mixture into a high speed blender or food processor and blend until creamy. Add creamed soup back into your pot and stir with a wooden spoon or spatula. This makes for an extra creamy texture!

Once mashed and blended, continue to cook on low heat for 5 minutes. Add more milk if you want it thinner.

Divide into bowls and top each bowl with a little cheese, green onions, and additional salt and pepper to taste
