Add sausages and sauté for 3 minutes.
6 sausages
Add crushed tomatoes, tomato paste, water, oregano, basil, garlic, salt and bay leaf. After adding these ingredients, make sure to scrape the bottom of the instant pot to avoid any burn notice.
28 ounces crushed tomatoes, 6 ounces tomato paste, 12 ounces water, 2 teaspoons garlic paste, 2 teaspoons dried oregano, 2 teaspoons dried basil, 3/4 teaspoon salt, 1 bay leaf
Seal instant pot, make sure the venting knob is set to sealed and press the pressure cook button and set the timer for 15 minutes. The mode should be normal and the pressure set to high.
IP will take between 10 - 15 minutes to come to pressure, and then the timer will start counting down.
Once it beeps, either let the IP release the pressure naturally, or do a fast release but use an oven mitt before tapping the venting knob.
Plate some pasta and either transfer the sauce to a serving bowl or serve directly out of IP container.
