Man That’s Cooking
Ingredients
- 5 pounds russet potatoes
- 4 heads of garlic
- 1 ½ sticks salted butter
- 1 cup heavy whipping cream
- 1 cup sour cream
- 1 sprig fresh thyme
- 1 tablespoon salt
Directions
Preheat the oven to 400°F (200°C). Cut the tops off 3 heads of garlic (the side without roots) and place each on its own sheet of foil. Drizzle olive oil over each garlic head, then wrap them tightly in foil. Roast for 45 minutes or until the garlic cloves are soft and golden brown. Let the garlic cool for 10 minutes, then squeeze out the roasted cloves into a small bowl and set aside.
Take the 4th head of garlic, separate the cloves, and peel off the paper. Set the peeled garlic cloves aside to add to the pot when boiling the potatoes.
Peel the russet potatoes and cut them into 2-inch cubes to ensure even cooking. Place the cubed potatoes in a large pot, add 1 tablespoon of salt, and cover them with cold water. Add the peeled raw garlic cloves to the pot.
Bring the water to a boil over high heat, then reduce the heat to medium-low and simmer for 15 to 25 minutes, or until the potatoes are fork-tender and break apart easily. Drain the potatoes and garlic cloves in a colander, allowing them to sit for 5 minutes to release any excess moisture.
While the potatoes are cooking, melt 1 ½ sticks of salted butter in a medium-sized skillet over medium heat. Reduce the heat to medium-low, then stir in the heavy whipping cream and sour cream. Add the roasted garlic cloves and the sprig of thyme to the butter mixture, stirring gently to combine. Remove the skillet from the heat and set aside.
Discard the boiled garlic cloves from the potatoes. Use a potato masher to break down the potato chunks directly in the pot. Alternatively, pass the potatoes through a potato ricer for an ultra-smooth texture. Keep the potatoes on low heat to stay warm.
Gradually fold the butter cream mixture into the mashed potatoes, stirring gently until everything is well combined and creamy. Taste and adjust seasoning if needed. Serve warm as a side dish for your favorite main course.
