Place the olive oil in the insert of the Instant Pot and turn on Sauté mode.
Once hot, add the onions and cook for about 3 minutes until starting to soften.
Add the garlic, ground beef, oregano, paprika, salt and pepper to the Instant Pot and cook until beef is browned, breaking up with a spatula as it cooks.
Add the carrots and celery and cook for another 3 minutes.
Turn off Sauté mode and add the remaining ingredients to the insert of the Instant Pot.
Close the lid, turn the dial to the "sealing" position and cook on Manual mode for 10 minutes. It will take about 10-15 minutes for the Instant Pot to come to pressure before cooking time starts.
After the 10 minutes of cooking time when the timer alerts, manually release the pressure by turning the dial to "venting".
Open the lid and stir in the fresh parsley and oregano. Season to taste with additional salt and pepper as needed and serve.
