Prepare your beets: Slice your beets in half, down the center, then cut both ends off. Peel beets after slicing them.
Prepare your Instant Pot: fill the bowl with 1 cup of water, then place steaming rack inside. You'll place your beets on top of the steaming rack so they won't get soggy, sitting in the water. Close lid, and set knob to sealing.If using a stovetop pressure cooker: follow same instructions as above, just heat cooker over high heat and adjust after cooker pressurizes to maintain high heat.
Cook the beets on the MANUAL setting for 15 minutes. Once cooking is finished (remember it will take about 25-30 minutes to cook), let pressure release naturally for 10-15 additional minutes before turning knob to venting to release steam. This will ensure that your beets are cooked and soft.
Open lid and pierce the larger beet with a fork. If beet feels soft, they're done. Fork will go into and come out of beet easily if it's done. If not, repeat the process. Just set timer for 5-10 minutes instead of 15.
You can discard your peels in a tabletop compost bin.
If you already have one, use your steamer basket, it's easier to get the beets out. Plus they are less likely to get soggy because they won't be sitting in the water as they're cooking.
If you'd like to cook them for longer, repeat the process. Just set timer for 5-10 minutes instead of 15.
