Ingredients for Perfect Brown Butter Garlic Mashed Potatoes

The Essentials

• 3 pounds Yukon Gold potatoes, peeled and cut into 1-inch chunks
• 1 whole garlic head
• 8 tablespoons (1 stick) unsalted butter
• 1 cup whole milk, warmed
• 1/2 cup heavy cream, warmed
• 2 teaspoons kosher salt, plus more to taste
• 1/2 teaspoon freshly ground black pepper
• 2 tablespoons fresh chives, finely chopped (optional, for garnish)

Ingredient Notes and Substitutions

For a flavor variation perfect for Christmas recipes dinner menus, consider adding 1 tablespoon of fresh rosemary or thyme to the butter as it browns. The herbs will infuse the butter with their essence, creating an aromatic holiday-worthy version.

How to Make Brown Butter Garlic Mashed Potatoes

Preparing the Garlic and Potatoes

1. Preheat your oven to 400°F (200°C).
2. Cut the top quarter off the garlic head to expose the cloves. Place on a small piece of aluminum foil, drizzle with 1 teaspoon of olive oil, and wrap tightly. Roast in the preheated oven for 35-40 minutes until cloves are golden and soft.
3. Meanwhile, place potato chunks in a large pot and cover with cold water by 1 inch. Add 1 tablespoon salt to the water.
4. Bring potatoes to a boil over high heat, then reduce to medium-high and simmer until potatoes are fork-tender, about 15-20 minutes.
5. While potatoes cook, prepare the brown butter.

Creating the Brown Butter Magic

1. In a medium light-colored saucepan (to better see the color changing), melt the butter over medium heat.
2. Once melted, continue cooking, swirling occasionally. The butter will foam, then the foam will subside, and the milk solids will begin to turn golden brown and smell nutty, about 5-7 minutes total.
3. Watch carefully as brown butter can quickly burn. When it reaches a medium amber color and smells toasty, remove from heat immediately.
4. Squeeze the roasted garlic cloves from their skins into the brown butter and mash with a fork to incorporate.
5. Add the warmed milk and cream to the butter-garlic mixture and stir to combine. Keep warm.

Bringing It All Together

1. Drain the potatoes thoroughly in a colander, then return them to the hot pot. Allow them to steam dry for 2 minutes.
2. For extra smooth potatoes, pass them through a food mill or ricer. For a more rustic texture, use a potato masher.
3. Gradually pour in the warm brown butter and milk mixture, folding gently with a rubber spatula until incorporated.
4. Season with salt and pepper, tasting and adjusting as needed.
5. Transfer to a serving bowl, top with a pat of regular butter if desired, and sprinkle with fresh chives for a pop of color and flavor.

For the perfect Thanksgiving recipes easy side dish, make these potatoes up to 2 hours ahead and keep them warm in a slow cooker on the low setting, adding a splash of warm cream just before serving to refresh the texture.

Storage & Reheating Tips

Keeping Your Mashed Potatoes Perfect

These Brown Butter Garlic Mashed Potatoes are excellent candidates for make-ahead Thanksgiving recipes. You can prepare them up to 2 days in advance and store them in an airtight container in the refrigerator.

Reheating for Best Results

The secret to perfectly reheated mashed potatoes is adding moisture back in. When reheating from the refrigerator, place the potatoes in a microwave-safe bowl, cover with a damp paper towel, and heat in 1-minute intervals, stirring between each until hot. Add a splash of warm milk or cream and a small pat of butter if needed to restore creaminess.

For larger portions, place in a buttered baking dish, cover with foil, and heat in a 350°F oven for about 30 minutes, stirring halfway through. For the ultimate convenience on Thanksgiving Day, transfer cold mashed potatoes to a slow cooker and heat on low for 2-3 hours, stirring occasionally.
