In a small saucepan on low heat, heat olive oil and cook minced garlic until just until fragrant and softened (about 1 minute). Set aside. The garlic will continue to cook in the now-garlic-infused olive oil.
2 Tbsp extra virgin olive oil
Meanwhile, place peeled potatoes in a large pot of slightly salted water, bring to a boil, and cook until potatoes are tender and can easily be pierced with a fork (about 15 to 20 minutes). Drain the water from the pot.
Transfer potatoes back to the pot, add in the garlic and garlic-infused olive oil, and mash them until well combined.
Add butter, salt, pepper, and cream (or milk). Mix until the potatoes are smooth and creamy.
1/4 cup unsalted butter, softened
1 tsp kosher salt
⅓ - ½ cup heavy cream, half-and-half, or milk
1 tsp ground black pepper
Taste potatoes and check for proper seasoning. Add additional salt as necessary. Serve hot.
