Step 1

To make this process as simple and smooth as possible, start by fully preparing all of your ingredients before you begin cooking. Grate your cheese, measure out all of your ingredients, and peel and prep your potatoes—then, once you start cooking, it’ll be a breeze.

Step 2

Place the potato chunks and garlic cloves into a large pot. Cover with water, add a tbsp of salt, and bring to a boil over medium-high heat. Boil until the potatoes are fork-tender, about 10-12 minutes.

Step 3

Drain the potatoes and garlic thoroughly in a colander. Return them to the hot pot and place the pot back on low heat for 1-2 minutes to help evaporate any excess water.

Step 4

Add the cubed butter while the potatoes are still warm.

Step 5

Stir in the sour cream, buttermilk, and heavy cream. Start with 1/4 cup of heavy cream and add more gradually until you reach your desired consistency.

Step 6

Fold in the freshly grated Parmesan and Asiago cheeses.

Step 7

Add the fine sea salt, white pepper, and garlic powder. Stir until the cheese is fully melted and combined with the potatoes. Taste and adjust the seasonings as needed.

Step 8

Using a potato masher, mash the potatoes and garlic directly in the pot until smooth - with the rest of the ingredients.

Step 9

If the mashed potatoes seem too thick, add a splash of warm buttermilk or cream until they’re as creamy as you like.

Step 10

Take 6 tablespoons of either unsalted or salted butter, depending on your preference, and melt it in a saucepan over low-medium heat. Once melted, add 10 cloves of roughly chopped garlic. Sauté the garlic for 1 to 1 1/2 minutes to infuse the butter with a delicious garlic aroma. This will make an incredible topping for your mashed potatoes.

Step 11

Be careful not to brown the butter or the garlic; you just want to infuse the butter with flavor. After the 1 1/2 minutes are up, strain the garlic out of the butter. Now you have the perfect garlic-infused butter to drizzle over your completed mashed potatoes.

Step 12

Transfer the mashed potatoes to a serving dish, garnish with your garlic infused butter, fresh chives, sprinkle of extra Parmesan or a pat of butter if desired, and serve warm.
