Preheat the oven to 400°F. Place unpeeled garlic cloves on a small piece of foil, drizzle lightly with olive oil, wrap, and roast for 20 minutes until soft.
While the garlic roasts, place the potatoes in a large pot, cover with cold water, and add a pinch of salt. Bring to a boil, then simmer for 15–18 minutes until fork-tender. Drain well.
Squeeze the roasted garlic from skins and mash into a smooth paste.
In the same pot, return the potatoes and mash until mostly smooth. Add the roasted garlic, butter, cream cheese, cheddar, milk, salt, and pepper, stirring until creamy and well combined.
Sprinkle with fresh chives before serving.
Enjoy!
