  • How Long to Boil Potatoes for Mashed Potatoes: Not sure how long to boil your potatoes? My video explains how long it takes to boil different-size potatoes. 
  • Are your homemade mashed potatoes too thick? Add a little broth to thin them out.

🗒 Variations

  • Boursin: For a different flavor profile, use another flavor of Boursin, like basil and chive or cracked black pepper.

🗒 Substitutions 

  • Not a garlic fan? Use half of a head or omit it.
  • Cheese: Swap Boursin for cream cheese or goat cheese.
  • Herbs: Substitute any fresh or dried herbs, like chives, rosemary, sage, or thyme.
  • Dairy-Free Mashed Potatoes: Substitute Boursin with unflavored, unsweetened plant-based milk (Oat milk works best) and butter with vegan butter, like Miyoko’s oat butter.

👝 How to Store Mashed Potatoes

You can eat these mashed potatoes warm immediately after making them or prepare them a day before you serve them. 

  1. Put the mashed potatoes in a casserole dish and wrap tightly with plastic wrap.
  2. Refrigerate overnight.
  3. Preheat the oven to 350℉, and reheat, covered, for 30 minutes until warm in the center.

Homemade mashed potatoes will last for three to five days in an airtight container in the refrigerator. I don’t recommend freezing them.

🤔 Common Questions

What makes the best mashed potatoes?

Russet or Yukon Gold potatoes are my favorite for creamy mashed potatoes. You also want to use more than one dairy source, so I use cheese and butter.

What adds flavor to mashed potatoes?

There are so many things to add to mashed potatoes for flavor. I use roasted garlic, garlic Boursin, salt, pepper, and fresh herbs for this garlic mashed potatoes recipe. Using good-quality butter also helps.

Do you put hot or cold butter in mashed potatoes?

Letting the butter and cheese come to room temperature will make it easier to mix into the potatoes.
