Switch your pressure cooker to the SAUTE function and sauté onion in 1 TBSP oil for 3-5 minutes, until edges are golden and tender.
Add garlic at very end and cook 30 seconds more while stirring.
To deglaze any browned bits of onion from the pot, add vegetable broth and scrape with spatula.
Add chopped carrots, seasoning (salt, pepper, oregano, basil, and optional sugar) along with canned tomatoes and tomato paste.
Set to HIGH pressure for 15 minutes and allow to come to pressure, allowing a natural pressure release for about 10 minutes.
Use a hand held immersion blender to puree until fabulously smooth.
Lastly, give the soup a taste and adjust broth/tomato/seasoning to taste, adding any extra of whatever you prefer to get your ideal thickness and flavor.
Serve piping hot with a melty grilled cheese sandwich and enjoy!
