Tips for the Best Instant Pot Mashed Potatoes
- Choose the Right Potato: Use starchy russet potatoes for the fluffiest, creamiest Instant Pot mashed potatoes—waxy varieties can turn gummy or gluey.
- Cut Evenly: Chop potatoes into uniform pieces about 1½ inches to ensure even cooking and avoid undercooked chunks or overcooked mush.
- Avoid Overcooking: Stick to the 10-minute pressure cook time; overcooked potatoes absorb too much water and become watery when mashed.
- Drain Thoroughly: Always drain any leftover cooking water before mashing to keep mash creamy, not watery or gluey.
- Warm Dairy Ingredients: Heat butter and milk before adding them to prevent cooling the mash and to keep texture luxuriously smooth.
- Season at the End: Add salt and pepper after mashing to better control flavor, making those comforting Instant Pot mashed potatoes taste just right.
