Switch in the Instant Pot On, to SAUTE MODE for 5 mins.
Once the display shows HOT, add oil to it.
Then add finely chopped onions, minced garlic and sauté for about a minute.
If adding veggies, add now and sauté lightly. Take out before adding spinach puree. I added corn, and cooked along with pasta.
Add pureed spinach. I had spinach puree, so I used that. You can add fresh finely chopped spinach sauté for about 1 one minute.
Add sweet corns(optional) and then add pasta.
Add pasta and then add water. Since I added spinach puree, I added 1¾Cup, ¼ Cup less water. For 2 Cups pasta you can add 2 cups water when adding finely chopped spinach.
Cancel the SAUTE MODE, put on the lid and Switch on the PRESSURE COOK MODE. Set the Timer to 4 Mins. Check the time for cooking on pasta box and set accordingly .
I have used Rotini Pasta, with cooking Time 7 mins. So, Instant Pot Cooking Time for this is 4 mins.. Many people keep 1 min. less than the half of actual pasta cooking time. But for me, 4 mins gives us soft pasta that my kids like to have.
Once time is done, do the Quick Release of Pressure. Open the lid.
Add cream, black pepper powder, Italian herbs and grated cheese.
Mix everything lightly.
Serve hot.
