This complete guide explains boiling times for whole potatoes, diced potatoes, baby potatoes, russet potatoes, red potatoes, and more—plus tips to get perfect results every time.
How Long to Boil Potatoes? (Quick Answer)
Here are the basic boiling times:
| Type of Potato | Boiling Time |
|---|---|
| Whole large potatoes | 20–30 minutes |
| Diced potatoes (1-inch pieces) | 10–15 minutes |
| Baby potatoes | 12–15 minutes |
| Russet potatoes | 20–25 minutes |
| Red or Yukon potatoes | 15–20 minutes |
| Potatoes for mashed | 15–20 minutes |
| Potatoes for salad | 10–15 minutes |
Now let’s break it down in detail.
Boiling Times by Type of Potato
1. How Long to Boil Whole Potatoes
Whole potatoes take the longest to boil because heat must travel deeper into the potato.
Time: 20–30 minutes
Smaller potatoes cook faster, while large russets take longer.
How to Boil Whole Potatoes
- Place potatoes in a pot.
- Cover with cold water.
- Add 1 teaspoon of salt.
- Bring to a boil.
- Simmer 20–30 minutes.
- Test by poking with a fork—it should slide in easily.
Whole potatoes are best for:
- Baked-style boiled potatoes
- Potato skins
- Recipes requiring firm texture
2. How Long to Boil Diced Potatoes
Cutting potatoes into chunks speeds up boiling time significantly.
Time: 10–15 minutes
Pieces around 1 inch thick cook evenly and quickly.
Diced potatoes are perfect for:
- Mashed potatoes
- Soups
- Stews
- Curries
- Egg and potato dishes
3. How Long to Boil Baby Potatoes
Baby potatoes boil quickly because of their small size.
Time: 12–15 minutes
They become tender while staying firm enough for:
- Herbed butter potatoes
- Roasted-style boiled potatoes
- Potato salads
4. How Long to Boil Russet Potatoes
Russets are starchy and fluffy—great for mashing and baking but they fall apart easily.
Whole russets: 20–25 minutes
Diced russets: 12–15 minutes
These potatoes absorb water quickly, so avoid overcooking.
5. How Long to Boil Red or Yukon Gold Potatoes
These are “waxy” potatoes. They hold their shape better than russets.
Time: 15–20 minutes (whole or halved)
Diced: 10–12 minutes
Perfect for:
- Potato salad
- Boiled potato sides
- Soups
- Roasting after boiling
6. How Long to Boil Potatoes for Mashed Potatoes
Time: 15–20 minutes
Use diced russets or Yukon golds for creamy, smooth mashed potatoes.
Steps:
- Peel and dice potatoes.
- Start in cold water.
- Boil 15–20 minutes until very soft.
- Drain well.
- Mash with butter, milk, salt, and seasoning.
7. How Long to Boil Potatoes for Potato Salad
Potato salad needs tender but firm potatoes.
Time: 10–15 minutes
Best potatoes:
- Red potatoes
- Yukon Gold
They hold shape better than russets.
How to Tell Potatoes Are Done
Potatoes are fully cooked when:
- A fork easily slides into the center
- They break apart with gentle pressure
- The color becomes lighter
- The edges look soft
If potatoes are mushy and falling apart, you’ve overboiled them.
Tips for Perfect Boiled Potatoes
1. Start with cold water
This ensures even cooking from the inside out.
2. Salt the water
Salt enhances flavor and seasons the potatoes from within.
3. Keep pieces equal in size
Uneven pieces = uneven cooking.
4. Avoid overcooking
Mushy potatoes ruin texture, especially for salad.
5. Drain immediately
Leaving boiled potatoes in water makes them soggy.
6. Dry potatoes briefly after boiling
For mashed potatoes or roasting, let steam escape for fluffier texture.
Flavor Boost Options
Make boiled potatoes more delicious by adding:
To the water:
- Garlic cloves
- Bay leaves
- Rosemary
- Butter
- Chicken broth
After boiling:
- Herb butter
- Olive oil + seasoning
- Sour cream
- Parmesan cheese
- Lemon and herbs
These additions turn simple boiled potatoes into something special.
Why Boiling Time Depends on Potato Type
Potatoes differ in texture:
Starchy potatoes (Russets):
- Absorb water fast
- Cook faster but fall apart easily
Waxy potatoes (Red, Yukon Gold):
- Hold shape better
- Take slightly longer
New potatoes / baby potatoes:
- Small, thin-skinned
- Cook quickly
Understanding this helps you boil each type perfectly.
