Instructions
Add the potatoes to a large pot and cover with water by 1 inch. Add 1 ½ teaspoons salt, then bring to a boil over high heat. Reduce heat to medium and simmer for 10-15 minutes, or until fork-tender. Drain in a colander and set aside.
3 pounds Yukon gold potatoes
Return the pot to medium heat and add 8 tablespoons butter. Cook, stirring occasionally, for 5-7 minutes, or until the butter turns golden brown and develops a nutty aroma. (Keep a close eye on this, it can turn quickly!) Remove from the heat immediately and set aside 2 tablespoons of brown butter for serving.
8 tablespoons salted butter
Add the garlic to the brown butter in the pot, stirring constantly for 30 seconds, or until fragrant. Stir in the thyme, remaining 1 teaspoon salt, and black pepper until combined.
4 garlic cloves, ¾ teaspoon dried thyme, ½ teaspoon black pepper
Return the potatoes to the pot and pour in ¾ cup of warmed milk. Mash everything together using a potato masher or large fork until smooth, adding more milk as needed to reach your desired consistency.
¾-1 cup milk
Serve immediately with the reserved brown butter, extra thyme, salt, and black pepper, if desired.

Notes
Choosing the Right Potatoes: Yukon gold potatoes are best for mashed potatoes since they have a naturally creamy texture. If using Russet or red potatoes, expect a slightly different consistency.
Perfectly Browned Butter: Watch closely—brown butter can go from nutty perfection to burnt in seconds. Remove from heat as soon as it turns golden and smells toasty.
Milk Temperature Matters: Using warmed milk helps keep the mashed potatoes silky smooth and prevents them from cooling down too much.
Make-Ahead Tip: Prep these up to 24 hours in advance. Reheat with a splash of milk over low heat, stirring until creamy.
Extra Creaminess: Swap half of the milk for heavy cream or stir in ½ cup of sour cream for an even richer taste.
