I’m going to go out on a limb and say that mashed potatoes are the best side dish! I rarely make them, though, because peeling and boiling and mashing is such a hassle.

Enter the Instant Pot. Cooking the potatoes in the Instant Pot is essentially steaming the potatoes so we can get away with using A LOT less liquid. Just enough to not get a “burn” warning, really. The potatoes steam and then the extra liquid evaporates when we mash the potatoes.

Ingredients

Potatoes: I recommend using good ol’ russet potatoes or yukon gold potatoes. Peeling is completely optional. If you choose not to peel the potatoes, make sure to scrub them well before cutting into 1 inch chunks. I have not tested this recipe with red potatoes, but I’m sure they will work well, too.

Cooking Liquid: I call for using water or vegetable stock in order to keep these potatoes vegetarian-friendly. Feel free to use chicken stock if you desire.

Garlic: For the garlic, all you need to do is smash the cloves of garlic with the side of your knife. Lay the clove on your cutting board and place the flat side of your knife on top of the clove. Using the open palm of your hand, hit the blade to squish the clove. It will break open the clove so that it will slip right out of the skin. There is no need to chop the garlic. The cloves will soften while cooking and mash beautifully with the potatoes.

Rosemary: You can use either fresh or dried rosemary. If using fresh, strip the leaves off of the sprig and pile them on your cutting board. Chop the rosemary until it is very finely minced. Measure out 1 tablespoon once chopped. If using dried, use 1 teaspoon. Dried herbs are more potent than fresh so you don’t need as much.

Milk: Feel free to use milk, half and half or heavy cream here. I use milk because it is what I have on hand. Half and half or heavy cream will add even more richness to the potatoes.

Butter: You can use salted or unsalted butter. In this savory recipe, the type of butter doesn’t matter. You will want to cube the butter into smaller pieces so that it melts into your mashed potatoes more quickly than a whole stick.

Variations of Instant Pot Mashed Potatoes

If you’re not feeling rosemary garlic, feel free to make any of the following substitutions:

  • Leave out the garlic altogether
  • Replace rosemary with chopped chives
  • Use sour cream buttermilk or cream cheese in place of the milk for a tangy flavor
  • Try olive oil instead of butter

Ingredients

  • 3 pounds Russet potatoes, peeled and cut into 1 inch chunks
  • 6 Garlic cloves, peeled and smashed
  • 1 Tbsp fresh Rosemary, finely chopped (or 1 tsp. dried)
  • 1 cup Water or Vegetable broth
  • 2 tsp Salt

Notes

Freezer Storage and Reheating

Once potatoes are fully prepared, allow to cool completely. Place in a covered container or gallon size freezer bag. Release all excess air from the bag or container and freeze. To reheat: allow potatoes to thaw in fridge overnight. Place in a microwave-safe bowl and microwave for 3-4 minutes. Stir well to reincorporate butter. Microwave for 1-2 additional minutes until heated through.

Variations

Feel free to substitute rosemary for any herb. You can also use cream cheese or sour cream in place of the milk or heavy cream.
