In the instant pot, heat the oil on saute mode.
Add carrots, beets, potatoes, and cabbage and saute for a minute.
Add water or vegetable broth and tomato puree.
Season with salt and black pepper.
Close the lid of the IP and put it on the pressure cooker for 4 minutes.
After pressure cooking is over allow the IP to stand for 4 minutes and then force release the pressure by moving the valve to ventilate position.
Borscht is ready to serve.
As a personal preference, I take out ½ of the veggies and then blend the rest of the veggies with a stick blender.
this gives a creamy consistency soup. Then I return the veggies back into the soup and serve it topped with sour cream.
