FAQs
Can I leave the skins on?
Yes, especially if using Yukon Gold potatoes. It adds texture and nutrients.
Do I need to drain the potatoes?
No, the small amount of water used is absorbed or can be mashed in.
Can I use red potatoes?
Yes, but they’re waxier, so the texture may be a bit different—less fluffy, more creamy.
How do I avoid gluey mashed potatoes?
Use a masher or ricer, and avoid overmixing, which breaks down the starches too much.
Can I make these ahead?
Absolutely. Reheat gently and add a splash of milk or butter before serving.
Can I double this recipe?
Yes, just don’t fill the Instant Pot past the max fill line.
What if I want them extra smooth?
Use a potato ricer for the smoothest texture.
How do I make them more flavorful?
Use broth instead of water, or add roasted garlic, cheese, or herbs.
