Cooking mini potatoes in the Instant Pot is one of the fastest, most reliable ways to get tender, flavorful potatoes with minimal effort. Whether you’re preparing a side dish for a weeknight dinner, meal prepping for the week, or need a quick addition to a potluck, the Instant Pot streamlines the process. In just a few simple steps, you can have perfectly cooked mini potatoes—creamy inside, with skins that hold their shape—ready for seasoning or mashing as you like.
What You’ll Need
- 1-2 pounds mini potatoes (red, yellow, or fingerling; whole and unpeeled)
- 1 cup cold water
- Salt, pepper, and preferred seasonings (optional, for after cooking)
- Instant Pot (any size, but times here assume a 6-quart or 8-quart model)
- Steamer basket or trivet (optional, but recommended)
- Long-handled spoon or tongs for removing hot potatoes
Step-by-Step
- Wash the potatoes. Rinse your mini potatoes thoroughly under cool running water. Gently scrub to remove any dirt. Leave the skins on for best texture and flavor.
- Add water to the Instant Pot. Pour 1 cup of cold water into the bottom of the Instant Pot insert. This is essential for creating steam and building pressure.
- Set up the steamer basket or trivet. Place a steamer basket or the metal trivet that came with your Instant Pot inside the pot. This keeps the potatoes above the water so they steam instead of boil, avoiding sogginess. If you don’t have a basket, you can rest the potatoes directly on the trivet or, as a last resort, in the water (though texture may be slightly different).
- Add the potatoes. Arrange the washed mini potatoes in a single layer on the basket or trivet. It’s fine if they’re slightly stacked, but avoid overfilling as this can lead to uneven cooking.
- Seal and set the pressure. Lock the Instant Pot lid in place, ensuring the valve is set to the sealing position.
- Pressure cook. Select the “Manual” or “Pressure Cook” setting. Set the timer for 5 minutes on HIGH pressure for small bite-sized potatoes (about 1 inch in diameter). For larger mini potatoes (up to 2 inches), set for 7-8 minutes. Note: The pot will take about 8-10 minutes to come up to pressure before the timer starts.
- Natural release for 5 minutes. Once the timer beeps, let the pressure release naturally for 5 minutes. This helps finish cooking and prevents skins from bursting.
- Quick release any remaining pressure. Carefully turn the valve to “venting” to release any remaining steam. Use a towel or long utensil to keep your hand away from the steam.
- Open the lid and check for doneness. Open the lid away from your face. Test a potato with a fork—if it slides in easily, they’re done. If not, reseal the lid and pressure cook for 1-2 more minutes.
- Season and serve. Transfer potatoes to a bowl. Toss with salt, pepper, a drizzle of olive oil, or your favorite herbs (like parsley, dill, chives, or rosemary). Serve hot as a side dish, or cool and use in potato salads.
Common Mistakes
- Not enough water: Less than 1 cup of water may cause a “burn” warning or prevent the Instant Pot from coming to pressure.
- Overcrowding: Overfilling the basket or pot can lead to uneven cooking, with some potatoes underdone and others mushy.
- Skipping the natural release: Releasing pressure immediately can cause potato skins to split and the insides to become mealy.
- Cooking too long: Overcooked mini potatoes can become waterlogged and mushy, losing their pleasant texture.
- Not washing potatoes: Dirt and debris left on the skin can affect taste and texture.
Tips
- Use similar-sized potatoes: This ensures all cook at the same rate and finish evenly.
- Flavor with aromatics: Add a few garlic cloves, sprigs of rosemary, or bay leaves to the water for subtle flavor infusion.
- Finish under the broiler: For crispy skins, transfer cooked potatoes to a baking sheet, drizzle with oil, and broil for 3-5 minutes.
- Make ahead: Cooked mini potatoes store well in the fridge for up to 4 days. Reheat in the microwave or a hot skillet.
- Try different varieties: Red, yellow, and fingerling potatoes all work well. Each has a slightly different flavor and texture.
- Perfect for potato salads: Cool cooked potatoes, cut in half, and toss with vinaigrette or mayo-based dressing for a quick salad.
- Season after cooking: Salt added before cooking can toughen skins—season after for best results.
Troubleshooting
- Potatoes are undercooked: If potatoes are still firm after opening the lid, reseal the Instant Pot and cook for an additional 1-2 minutes at high pressure, then quick release.
- Potatoes are overcooked/mushy: Reduce cook time by 1-2 minutes next time. For now, use overcooked potatoes for mashing or in soups.
- Skins are split: This usually happens if pressure is released too quickly. Next time, let pressure release naturally for at least 5 minutes.
- Water left in the pot: Remove potatoes with a slotted spoon or drain in a colander. Pat dry if needed before seasoning or broiling.
- “Burn” warning: This means the pot detected overheating, usually due to insufficient water. Always use at least 1 cup of water for a 6- or 8-quart Instant Pot.
- Pot won’t come to pressure: Make sure the sealing ring is properly in place, the valve is set to sealing, and there’s enough water in the pot.
Frequently Asked Questions
- Can I cook more than 2 pounds of mini potatoes at once?
- Yes, you can cook up to about 3 pounds in a 6- or 8-quart Instant Pot, but avoid filling above the “max fill” line. Add 1 cup of water and increase cook time by 1-2 minutes if the potatoes are tightly packed.
- Do I have to use a steamer basket?
- No, but it helps keep potatoes from sitting in water and becoming soggy. If you don’t have one, place potatoes on the trivet or even directly in the pot if needed, but results may vary slightly.
- Can I add butter or oil before cooking?
- It’s best to add butter or oil after cooking. Adding fats before pressure cooking can lead to separation or a greasy texture. Toss with melted butter or olive oil just before serving for best flavor.
- How do I store and reheat leftover mini potatoes?
- Cool cooked potatoes to room temperature, then store in an airtight container in the fridge for up to 4 days. Reheat in the microwave, oven, or a skillet with a little oil or butter.
- Can I use this method for regular potatoes?
- You can use the same technique for small whole Yukon Gold or red potatoes. For large russet potatoes, increase the cook time to 12-15 minutes and prick with a fork before cooking.
- Are Instant Pot potatoes good for mashing?
- Yes! Mini potatoes cooked in the Instant Pot mash easily. Just add butter, milk, and seasonings after cooking and mash to your desired consistency.
