Turn your Instant Pot to Saute. If the tomatoes are large, halve or quarter them, and place them in the Instant Pot.
Add the garlic, onions, olive oil, and salt and pepper, to the fresh and diced tomatoes and toss together until coated. Saute for 5-7 minutes, stirring often.
Turn the Instant Pot off and add all remaining ingredients, except the tortellini.
Lock the Instant Pot lid and turn the steam release vent to ‘sealing’. Set the pot to pressure cook for 5 minutes at high pressure.
Once the tortellini soup is finished cooking, allow the pressure to naturally release for an additional 10-15 minutes before opening the lid.
Blend the soup using an immersion blender.
Add the tortellini and heavy cream to the Instant Pot and turn to saute once more.
Cook for 3-4 minutes until the pasta is soft. Add salt and pepper as needed.
The tortellini soup is now ready to be served.
Ladle the soup into bowls and garnish with fresh basil leaves, freshly grated Parmesan cheese, and a drizzle of olive oil. Enjoy!
Notes
There are two main tricks to making this Instant Pot Tortellini Soup recipe a success.The first is that you want to ensure the tortellini floats freely and doesn’t get stuck to the bottom of your pressure cooker.The second tip is not to overfill your pot with too much liquid as it can prevent the pressure from building correctly.
