Wash red potatoes and cut them into quarters, leaving the skins on.
Place the potatoes in a large pot and cover them with water. Bring to a boil and simmer for about 10-15 minutes until the potatoes are fork tender.
Drain the potatoes and then return them back to the pot.
Add minced garlic, ranch seasoning mix, butter, salt, and milk. Use an electric mixer to blend the potatoes until they are light and fluffy. Gradually add the remaining milk until the mashed potatoes reach your desired consistency.
Serve immediately while warm and enjoy!
Notes
I usually use milk for this recipe but you can substitute with heavy whipping cream as well.
