See our Cooking Conversions Chart for help converting measurements!
- Bring a large pot of water to a boil. Add salt to the pot of boiling water, then bring it back to a boil.
- Add potatoes to water and boil for 20 to 25 minutes until tender.
- Drain water from the pot. Using a hand mixer on low, whip well until the potatoes are crumbly. Then, add half a stick of chopped butter to your pot with the potatoes.
- Continue mixing well until butter is fully mixed through and potatoes are creamy. Slowly add two cups of milk and salt and pepper while whipping.
- Add in melted butter if desired. Mix with spoon, then top with green onions if desired, and serve!
Instant Pot Potatoes
- Heat a 6 qt. Instant Pot and add peeled whole potatoes.
- Cover halfway with water (do not fully submerge).
- Secure the lid and cook on high pressure for 12 minutes.
- Release the pressure naturally. Carefully remove the inside pot and drain, then return to the cooker.
- Use a hand mixer on low to mash them, but be careful not to over-mix. Add in butter 1 tablespoon at a time while continuing to blend.
- When the butter melts and they're completely smooth, add whole milk. Blend well, then season with salt and pepper to taste.
- Creamiest mashed potatoes: Starting with the boiled potatoes and whipping them until fluffy, then slowly adding butter and milk, makes the creamiest potatoes. You can use a hand mixer to make mashed potatoes, but for ultra creamy mashed potatoes, pass them through a potato ricer after cooking!
- Make-ahead mashed potatoes: For a make-ahead mashed potatoes recipe you can prepare in the oven, follow the instructions above, then store until ready to serve (up to 3-4 days). When ready to serve, whisk an egg and brush it over the top. Bake at 350°F for 30 minutes, or until the top is slightly browned.
