Instant Pot Mashed Potatoes (No Drain!)

Instant Pot Mashed Potatoes cook peeled, chunky russet potatoes with minced garlic and seasonings under pressure without needing to drain. The potatoes are quickly cooked in water, then mashed in the pot with milk and seasoning until creamy. This hands-free method yields smooth mashed potatoes with a subtle garlic note and no-fuss cleanup, suitable as a simple side dish.

Description

This recipe cooks peeled, cut russet potatoes along with minced garlic and salt directly in the Instant Pot with water, eliminating the need to drain after cooking. Initially sautéing the garlic in olive oil enhances its flavor, and adding water prevents burning during pressure cooking. The potatoes cook under high pressure for about eight minutes, followed by a quick pressure release.

After releasing pressure, the potatoes are mashed directly inside the pot with milk added gradually to reach desired creaminess. Seasoned with salt and pepper, the mashed potatoes achieve a smooth, creamy consistency with a mild garlic undertone, without extra steps or dishes.

This method saves time and effort compared to stovetop boiling and draining, producing reliable, fluffy mashed potatoes. Nutritional info estimates serving six. Alternatives like Yukon gold potatoes require less liquid but same cooking time.

Ingredients

Servings
  • 1 tablespoon olive oil
  • 2 garlic minced, cloves
  • 1 cup water
  • 3 pounds russet potato peeled and cut into 2-inch chunks
  • 1 teaspoon salt plus more to taste, fine sea salt
  • ¼ teaspoon black pepper ground
  • ½ to ¾ cup milk or more, as needed, of choice

Instructions

  1. Press the Sauté button on your Instant Pot, and add in the olive oil. When the pot has heated up, add in the 2 cloves of minced garlic and briefly stir them. Press the Off button right away, so the garlic won't burn.
  2. As soon as the garlic smells fragrant, add the water to prevent it from burning. Use a wooden spoon or spatula to scrape the bottom of the pot, to make sure no garlic is stuck there. (This will prevent a Burn error later.)
  3. Add in the potatoes, salt, and pepper to the Instant Pot. There's no need to stir. Secure the lid, and move the steam release valve to "Sealing."
  4. Use the Manual or Pressure Cook button on your machine to cook at high pressure for 8 minutes. It will take roughly 8 to 10 minutes for the pot to come to pressure, so it will read "On" as it heats up, and then it will start the count-down as soon as the floating valve in the lid pops up.
  5. When the cooking cycle is complete and the screen reads LO:00, immediately move the steam release valve to "Venting" to release the pressure in the pot. Make sure your hand isn't over the vent, to avoid getting burned by the hot steam. When the floating valve in the lid drops, it's safe to open the lid.
  6. Use a fork to test the potatoes, to make sure they are tender, then use a potato masher to start mashing the potatoes. Add in the milk, starting with only ¼ cup at a time, until the potatoes are as creamy as you like. I usually end up using ¾ cup total for Russet potatoes. (See notes below if you use Yukon Gold, instead.) This is also the time to taste the potatoes and add more seasonings as you like. I typically use at least 2 teaspoons of fine sea salt total for 3 pounds of potatoes, and you can add any extras you like at this point, such as butter, sour cream, chives, or fresh thyme.
  7. Once the potatoes are seasoned to your liking, you can serve them warm right away. You can also use the Instant Pot's Keep Warm setting, to keep them warm for up to 3 hours. The mashed potatoes will firm up as they sit in the pot, so be sure to check on them again just before serving. You may need to add an extra splash of milk or water, to help loosen them up again. See tips in this post for reheating any leftovers, or making them ahead of time.

Notes

  • Nutrition estimates are based on almond milk and about six servings; actual values may vary.
  • If using Yukon Gold potatoes, expect to use less liquid while keeping the same cooking time.
