How to Cook Diced Potatoes in Instant Pot
Making Instant Pot cubed potatoes is such a simple recipe, that you are going to wonder why you ever bothered with that cumbersome pot of boiling water.
We are going to start with cubed potatoes, add them to the pressure cooker, and let it work its magic, then follow up with a quick release to reveal perfectly boiled potato cubes that are ready for your dinner or other recipes that call for boiled potato cubes.
Step 1: Prep the Russet potatoes by washing, peeling, and cubing them into 1 ½" pieces.
Step 2: Add 1 cup of water to the bottom of the pressure cooker and insert a vegetable steamer. Place the diced potato cubes into the Instant Pot and close the lid.
Step 3: Pressure cook the potatoes for 5 minutes on high (for mashed potatoes or do 4 minutes for potato salad), the pot will take about 10+ minutes to come to pressure beforehand. After the pressure cooking has finished, do a Quick Release of the pressure. Remove the potatoes from the Instant Pot.
The Instant Pot diced potatoes will be very soft and ready to use for another recipe like mashed potatoes!
- You can use the rack that came with your pressure cooker if you don't have the steamer basket, you just want to make sure to keep the potatoes out of the water so they don't get soggy during cooking.
- The recipe as written is intended to make potato cubes soft enough to get pureed into a dish like mashed potatoes. If you want to serve these as a steamed and cubed side dish, just cook them on High for 4 minutes until cooked through and they will still hold their shape.
- For best results, be sure to cut the potato cubes as uniformly as possible.
- You can cook up to 5 lb of potatoes at a time with this method, you'll still just need to use 1 cup of water.
- Mashed potatoes are so easy to make with these Instant Pot cubed potatoes! Just mash the pot potatoes in a bowl with a fork, add 4 oz butter, and combine until the butter is melted, add ⅔ whole milk or half & half; season to taste with salt and pepper.
It depends on your end goal. If you are planning on turning the Instant Pot boiled potatoes into mashed potatoes you don't need to add salt to the water. But, if you will be serving potatoes as a cubed side dish then, yes, you should add a little salt to the water.
To dice potato cubes start with medium-sized russet potatoes, red potatoes, or Yukon gold potatoes and cut them lengthwise into 4 sections and then cut each of the sections into 1 ½ chunks.
Peeling the potatoes is optional depending on what you're using them for.
Yes, you can buy either canned or frozen diced potatoes to make Instant Pot cubed potatoes, but we do not recommend that you purchase fresh potatoes already cut since they brown easily once they are cut.
How long you cook the potatoes depends on what you're doing with the finished recipe. If you're making mashed potatoes, you'll want to cook the potatoes on high for 5 minutes before doing a quick release of the remaining pressure.
For potato salad, you'll cook the cubed potatoes for 4 minutes before doing a quick release of the remaining pressure.
