Instant Pot Small Potatoes Cooking Time & Complete Guide

Cooking small potatoes in the Instant Pot is a quick and foolproof way to get perfectly tender, flavorful potatoes with minimal effort. Whether you’re meal prepping, making a side dish, or prepping ingredients for potato salad, the Instant Pot saves time and delivers consistent results. This guide will walk you through exactly how to cook small potatoes—such as baby potatoes, new potatoes, or fingerlings—in your Instant Pot, including timing, tips, and troubleshooting.

What You’ll Need

• Instant Pot (any size, but 6-quart is most common)
• 1-2 pounds small potatoes (baby potatoes, new potatoes, fingerlings, or similar)
• 1 cup water
• Steamer basket or trivet (optional, but recommended for best texture)
• Salt (optional, for seasoning)
• Olive oil, butter, or herbs for serving (optional)
• Tongs or slotted spoon (for removing potatoes)

Step-by-Step

1. Wash the Potatoes: Rinse your small potatoes thoroughly under cool running water. Scrub gently to remove any dirt, but do not peel. Small potatoes have thin, edible skins.
2. Add Water to the Instant Pot: Pour 1 cup of cold water into the bottom of the Instant Pot insert. This is essential for building the steam needed for pressure cooking.
3. Insert Steamer Basket or Trivet: Place a steamer basket or trivet inside the pot. While you can cook potatoes directly in the water, using a basket or trivet keeps them above the water, preventing sogginess and ensuring even cooking.
4. Add Potatoes: Arrange the washed potatoes in a single layer in the basket or on the trivet. If you have more than one layer, that’s fine, but try to keep them as evenly distributed as possible for uniform cooking.
5. Season (Optional): Sprinkle with a little salt if you like, or leave plain and season after cooking. You can also add garlic cloves or herbs to the water for subtle flavor.
6. Close the Lid & Set Valve: Secure the Instant Pot lid and set the steam release valve to the “Sealing” position.
7. Set Cooking Time: Use the “Manual” or “Pressure Cook” function. For small potatoes (1-2 inches in diameter), set to 5 minutes on high pressure. For extra-tender potatoes or slightly larger ones, go up to 6-7 minutes; for very tiny potatoes, 4 minutes may be enough.
8. Build & Release Pressure: The Instant Pot will take 5-10 minutes to reach pressure before the timer starts. When the cooking time is up, quick release the pressure by carefully moving the valve to “Venting.” Stand back from the steam.
9. Check Doneness: Open the lid. Use a fork or knife to pierce a potato—it should slide in easily. If not, reseal and cook for 1-2 more minutes.
10. Serve: Remove potatoes with tongs or a slotted spoon. Toss with olive oil, melted butter, herbs, or seasoning as desired. Serve warm or let cool for potato salad or meal prep.

Common Mistakes

• Overcooking: Small potatoes cook quickly. Even one or two extra minutes can make them mushy. Stick to the recommended times and use quick release.
• Not Using a Trivet or Basket: Cooking potatoes directly in water can lead to uneven texture or waterlogged potatoes. A trivet or basket helps maintain ideal texture.
• Not Enough Water: Less than 1 cup of water can cause a burn warning and prevent the pot from coming to pressure.
• Not Checking Size: Cooking time is for small potatoes (about 1-2 inches). Larger potatoes will need more time; cut them if needed or adjust timing.
• Forgetting to Season: While potatoes can be seasoned after cooking, salting before or adding aromatics to the water can enhance flavor.

Tips

• Uniform Size: Try to use potatoes of similar size for even cooking. If you have some larger ones, cut them in half to match the smallest.
• Flavor Boost: Add a bay leaf, a few garlic cloves, a sprig of rosemary, or peppercorns to the water for subtle infusion.
• Meal Prep: Cooked small potatoes store well in the fridge for up to 5 days. Cool quickly and store in an airtight container.
• Crisp Finish: After pressure cooking, toss potatoes with oil and roast in a hot oven or air fryer for 10 minutes for crispy skins.
• Potato Salad: Let potatoes cool before tossing with mayo or vinaigrette to avoid mushiness.
• Batch Cooking: You can cook up to 3 pounds at once in a 6-quart Instant Pot. The cooking time stays the same; it may just take longer to come to pressure.

Troubleshooting

• Potatoes Undercooked: If potatoes are still firm after pressure cooking, reseal the lid and cook for 1-2 more minutes at high pressure. The pot will come to pressure faster the second time.
• Potatoes Overcooked or Mushy: Use a shorter cook time next time (try 4 minutes for very small potatoes). For now, use the potatoes for mashed potatoes or potato salad.
• Burn Warning: If you see a burn warning, ensure there’s at least 1 cup of water in the pot and nothing is stuck to the bottom. Release pressure safely, add more water if needed, and restart.
• Pot Won’t Come to Pressure: Check that the sealing ring is in place, the valve is set to “Sealing,” and there’s enough water in the pot. Also, make sure the lid is locked.
• Potatoes Stuck to Basket: Let the potatoes cool for a minute, then gently shake or use tongs to remove. Lightly oiling the basket before cooking can help prevent sticking.

Frequently Asked Questions

Can I cook different types of small potatoes together?

Yes, as long as they are similar in size. If mixing colors (red, yellow, purple), the cooking time stays the same. Cut larger potatoes to match the smallest.

Should I pierce small potatoes before pressure cooking?

No, it’s not necessary. Small potatoes rarely burst in the Instant Pot. Piercing is only needed for large or thick-skinned potatoes.

Can I cook potatoes without a steamer basket?

Yes, you can place them directly on the trivet or even in the water, but texture is best with a basket or trivet to keep potatoes above the liquid.

How do I store leftover Instant Pot potatoes?

Cool them quickly, then store in an airtight container in the fridge for up to 5 days. Reheat by steaming, microwaving, or roasting.

Can I freeze cooked small potatoes?

Yes, but texture may change slightly. Freeze in a single layer, then transfer to a freezer bag. Use within 2-3 months for best quality.

Do I need to adjust the time for high altitude?

At elevations above 3,000 feet, add 1 extra minute of pressure cook time per 1,000 feet over 3,000 to ensure potatoes cook through.

With this method, your Instant Pot will deliver perfectly cooked small potatoes every time—ready to enjoy as a side, in salads, or as a healthy snack. Experiment with seasonings, use the tips above to customize your results, and refer back to troubleshooting if you run into any hiccups along the way.
