Turn Instant Pot to Sauté mode. Add olive oil, onions, carrots, salt and pepper. Sauté, stirring frequently, about 5 minutes, or until vegetables are getting soft. Add garlic and sauté for one minute, stirring constantly. Turn Instant Pot off.
Crush tomatoes with hands or cut with scissors. Add tomatoes and oregano to Instant Pot, scraping any brown bits from bottom of pot.
Turn Instant Pot to high pressure for 12 minutes. Allow 13-14 minutes for pot to come to pressure. When time is up, natural release for 10 minutes. Carefully release any remaining pressure.
Remove lid. With a stick blender, puree soup until smooth.
Stir in half and half, brown sugar, and basil. Taste, adjust seasoning, and serve.
Stove top directions: Use a large sauce pan or Dutch oven. Follow recipe as directed. Cooking times will be pretty similar.
For vegans: Substitute almond milk or canned coconut milk for the half-and-half. You can also just omit the half-and-half. The soup won't be as creamy with these changes.
Substitute approx. 4 lbs. fresh Roma tomatoes, peeled, for the canned tomatoes.
