These garlic parmesan mashed potatoes are the only mashed potatoes we want to eat! They're creamy and comforting and perfect for eating by the spoonful or smothering in gravy.

We've made many varieties of mashed potatoes over the years and we have a couple of tricks. First, we boil the garlic with the potatoes in the pot to infuse them with lots of garlic flavor. We also reserve a bit of the cooking water to loosen them up and make them extra creamy.

We like our mashed potatoes a bit rustic so we use a potato masher, but you can use a potato ricer to make them silky smooth. They're delicious as-is or sprinkle in some fresh herbs like thyme or rosemary for added herbaceous flavor.

Garlic parmesan mashed potatoes ingredients

This delicious parmesan mashed potatoes recipe requires just a few ingredients. Here's what you'll need:

  • Potatoes – most potatoes taste great when mashed. Yukon gold potatoes are our favorite because they're the most buttery, but russet potatoes, white potatoes, or red potatoes all work well.
  • Garlic – we add a generous amount of garlic to the boiling potato pot to infuse them with lots of garlicky flavor.
  • Cream – or whole milk, for added moisture and to make them silky smooth.
  • Butter – salted or unsalted butter, for added richness.
  • Salt + pepper – for seasoning, add to taste.
  • Parmesan cheese – for a boost of bold, tangy, cheesy flavor.

How to make garlic parmesan mashed potatoes

Garlic mashed potatoes are an easy and versatile side dish, and they're always a hit. All you need is a few ingredients and a potato masher. Here's how to make them in a few simple steps:

  1. Peel and place potatoes and garlic in a large pot and boil them until tender.
  2. Before you drain them, reserve about a cup of the cooking water (the starchy water helps make the potatoes extra creamy). Drain the rest of the water.
  3. Give the potatoes a good mash along with the cream, butter, salt, and pepper. Add a bit of the cooking water at a time until they become ultra-creamy.
  4. Lastly, stir in the parmesan cheese and serve!
