2 whole heads garlic, top third sliced off and discarded
•
olive oil
•
1 tablespoon sea salt
•
5 pounds Yukon Gold potatoes, peeled and cubed
•
1 cup sour cream
•
1 cup butter
•
1 (4 ounce) package cream cheese
•
salt and ground black pepper to taste
Instructions
Preheat the oven to 350 degrees F (175 degrees C).
Place garlic heads in a baking dish and drizzle each with 1 tablespoon olive oil.
Bake in the preheated oven until garlic is soft and brown, about 45 minutes.
Meanwhile, bring a large pot of water to a boil and stir in sea salt. Cook potatoes in salted water until tender, about 30 minutes. Drain.
Transfer potatoes to a large bowl; add sour cream, butter, cream cheese, salt, and black pepper. Cover the bowl with a lid or a piece of aluminum foil and let stand to soften butter and cream cheese, about 5 minutes.
Squeeze roasted garlic from cloves into potato mixture; mash potatoes until smooth, creamy, and thoroughly combined.
