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:
- Peel and place potatoes and garlic in a large pot and boil them until tender.
- 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.
- 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.
- Lastly, stir in the parmesan cheese and serve!

Yes, you can make them up to 3 days ahead of time and store them in the fridge. To reheat them, top them with a touch of cream and butter and warm them in the oven at 350 degrees Fahrenheit for about 20 minutes (or until warmed through). Give them a good stir and then serve.
