Potatoes are a kitchen staple, but getting them just right can be trickier than it seems. Whether you’re making creamy mashed potatoes, a tangy potato salad, or prepping for crispy fries, knowing how long to boil potatoes is key. Overcooking or undercooking can ruin the texture and flavor, but with the right timing, your potatoes will be perfect every time.
In this guide, we’ll cover boiling times for different potato types, sizes, and cooking purposes, plus tips to ensure consistent results.
How Long to Boil Potatoes: The Basics
Boiling times vary depending on the type and size of potato:
-
Small potatoes (baby or new potatoes): 10–15 minutes
-
Medium potatoes (cut into chunks): 15–20 minutes
-
Large potatoes (whole): 25–30 minutes
Always start potatoes in cold water, bring to a boil, then reduce to a simmer. This ensures even cooking and prevents the outside from overcooking while the inside stays firm.
How Long to Boil Potatoes for Mashed Potatoes
Mashed potatoes need to be soft enough to mash easily without lumps.
Steps:
-
Peel and cut potatoes into 1–2 inch chunks
-
Place in a pot of cold water and add a pinch of salt
-
Bring to a boil, then simmer for 15–20 minutes
-
Test with a fork—the potato should break apart easily
Tip: For extra creamy mashed potatoes, drain and mash while hot, adding butter and milk gradually.
How Long to Boil Potatoes for Potato Salad
Potato salad works best with potatoes that hold their shape. Overcooking can make your salad mushy.
Timing Guide:
-
Cut potatoes into bite-sized pieces
-
Boil for 10–15 minutes, depending on size
-
Test with a fork—should pierce easily but not fall apart
Pro tip: Use waxy potatoes (like Yukon Gold or red potatoes) for potato salad; they stay firm after boiling.
How Long to Boil Potatoes Before Frying
Boiling before frying helps achieve a crispy outside and fluffy inside.
Method:
-
Peel and cut potatoes into your desired shape
-
Boil for 5–7 minutes until just tender
-
Drain and let cool before frying
Tip: Parboiling prevents raw centers and reduces frying time.
How Long to Boil Potatoes Before Roasting
Pre-boiling can also improve roasted potatoes, giving a golden crust and fluffy interior.
Instructions:
-
Cut potatoes into chunks
-
Boil for 8–10 minutes until slightly tender
-
Drain and shake gently to roughen the edges (this creates extra crispiness)
-
Roast in the oven with oil and seasonings
Factors That Affect Boiling Time
Several things can influence how long your potatoes need to boil:
-
Potato type: Waxy vs. starchy potatoes
-
Size: Whole potatoes take longer than chunks
-
Altitude: Higher elevations may require slightly longer cooking times
Always test with a fork before draining to ensure the perfect texture.
